This resource has been developed by Leslie Beissel and Yvonne Cole as part of their requisite coursework for the Graduate Diploma in Secondary Education at Charles Darwin University. The idea for developing the resource stemmed from a need identified by FrogwatchNT for teachers to be adequately equipped to impart information about the importance of frogs and the environment and to prepare students for the arrival of Cane Toads. Given that such a large amount of information about frogs and Cane Toads already exists, the focus of the kit is to provide activities, worksheets and handouts to assist a teacher deliver a unit of work on frogs and Cane Toads. The driving force behind developing this resource was our passion for native frogs coupled with a personal interest in caring for the environment and our disquiet over how the arrival of Cane Toads in the Top End could be addressed. We relied on our knowledge and experience gained from many years employment in the fields of science, natural resource management and environmental education. The development of this kit would not have been possible without the support and advice of several experts in the field. We would like to personally acknowledge the following people: • Louise Fogg (Department of Employment, Education and Training) • Jan Herman (FrogwatchNT) • Suzanne Hyde (Nhulunbuy Christian School) • Graeme Sawyer (FrogwatchNT) • Kate Smith (Museum and Art Gallery of the Northern Territory) • Iolanthe Sutton (Charles Darwin University) • Teaching Staff at Marrara Christian School We hope that by providing this resource teachers are encouraged to discuss the arrival of Cane Toads with students, promote the importance of being actively involved with community organisations such as FrogwatchNT and help young people become responsible global citizens. Leslie Beissel and Yvonne Cole Fantastic Frogs and Terrible Toads Teacher Resource Kit 2 INTRODUCTION Fantastic Frogs and Terrible Toads: A resource kit for teachers seeks to provide a range of activities and ideas to assist teachers raise awareness of the importance of frogs and inspire students to take action to limit the impact Cane Toads will have on native fauna. Each section suggests learning activities that will enhance student’s knowledge of frogs and Cane Toads and encourage students to take action in their local environment. Each of the six sections is comprised of a series of activity sheets and handouts. These are prefaced with key questions that will be addressed in the section as well as a brief description of each activity (including answers where necessary). Activities will assist students meet a range of SOSE, Science and Learning Technology outcomes. A broad range of activities are suggested including word puzzles, comprehension exercises, paper craft, community activities, excursions and internet activities. The activities are mostly suited to middle and upper primary aged children, however children of all ages will benefit from learning about frogs and the threats Cane Toads pose. Fantastic Frogs and Terrible Toads Teacher Resource Kit 3 Overview of activities Section 1: Fantastic Frogs Activities focus on general facts about frogs such as the life cycle and diet of frogs, as well as some of the features that are unique to amphibians. Section 2: Frogs and the Environment Activities explore the habitat requirements of frogs, the concept of frogs as bioindicators, reasons for world-wide decline in frog populations and suggest practical ways to create a suitable habitat for frogs at school or home. Section 3: Northern Territory Frogs Activities encourage students to access information about frogs found in the Northern Territory. Students will learn how to identify frogs by learning to look out for distinguishing features and recognize common frogs by their call. Ideas for finding out more about frogs are also provided. Section 4: Terrible Toads Activities highlight differences between frogs and Cane Toads and provide specific information relating to the introduction and advancement of cane toads in Australia and the Northern Territory. Section 5: Combating Toads Activities are designed to get students to consider the impact Cane Toads are likely to have on native fauna as well as exploring methods available to combat toads. Section 6: Frog Fun Suggestions for a range of activities that can be used to compliment the delivery of sections 1-3 are offered. Activities can be used to introduce the topic of frogs (which will be especially useful for lower primary classes). The activities suggested would also suit a program for a ‘frog day’ to promote environmental awareness. Fantastic Frogs and Terrible Toads Teacher Resource Kit 4 Curriculum Mapping The primary curriculum focus of the resource kit lies within the learning areas of SOSE and Science. Relevant Northern Territory Curriculum Framework Learning Area links are outlined below (Table 1). In addition to the SOSE and Science curriculum focus, the resource may also provide an avenue for students to demonstrate the Essential Learnings outcome of Constructive Leaner 4. If students undertake activities that rely on using the internet (such as Activity 3.3) this may also contribute to Learning Technology outcomes. Indicators for each learning outcome are up to the discretion of individual teachers and will vary depending on the section(s) of the resource delivered and activities undertaken.

Teachers will need to access information relevant to the section(s) of the resource they plan to deliver prior to undertaking activities with students. Here are some suggestions: • Most school libraries have a range of books on amphibians. These will range from reference books to children’s stories to field guides. • Palmerston, Darwin and Taminmin public libraries also have a range of books on amphibians. • The DEET Education Library also has over 20 books and videos relating to frogs and Cane Toads. • There is a large amount of information on frogs available on the internet. Some of the interesting, fun, useful and/or student friendly sites we encountered include: www.frogwatch.org.au www.frogs.org.au www.qmuseum.qld.gov.au/features/frogs www.qmuseum.qld.gov.au/features/frogs/canetoad.asp www.allaboutfrogs.org/froglnd.shtml www.frogs.wwf.org.au/ www.amonline.net.au/factsheets/canetoad.htm www.canetoads.nt.gov.au www.nationalparks.nsw.gov.au/npws.nsf/Content/Cane+toads www.nationalparks.nsw.gov.au/npws.nsf/Content/Frogs www.itg.lbl.gov/Frog/ Fantastic Frogs and Terrible Toads Teacher Resource Kit 6 1.0 Fantastic Frogs Key Questions • • • • • What is an amphibian? How does an amphibian differ from other animals? What are the general physical characteristics of frogs? What are the different stages of a frog’s life cycle? What do frogs eat? Suggested Activities 1.1 Frog Features The aim of this activity is to introduce students to some specific features of frogs. The activity sheet is designed for use in upper primary. Students need to read a series of descriptions of ‘frog features’ and then match the description with the name of the feature. 1.2 Frog Facts By completing a series of addition, subtraction, multiplication and division calculations, students can fill in the missing words of four ‘Frog Facts’. Given the level of mathematics required, this sheet is suitable only for upper primary. Answers: 1. Toads; 2. Water and Tadpoles; 3. Toads and Cane Toad; 4. Breathe, Wet and Live. 1.3 Frog Life Cycle Diagram This activity provides a basic outline of the different stages of the life cycle of frogs. Students can write (or cut and paste) the label for each stage of the life cycle into the correct box after the teacher has explained the life cycle using other resources. 1.4 Life Cycle of Frogs This activity sheet is suitable for all ages. The table with the different stages of the frog life cycle can be filled in using reference books or observations of eggs/ tadpoles. Lower primary school children could draw a picture in the box instead of writing about the different stages. 1.5 Life Cycle Word Search Students search words relating to the life cycle of frogs. Left over letters placed at the bottom of the page provide students with the word ‘Metamorphosis’. 1.6 Frog Food This activity is designed to help students know the different types of food frogs eat. Designed for lower primary, students draw or write some of the different creatures frogs might eat. 1.7 Frog Food Word Search This word search will provide students with a good understanding of the diet of frogs. When all the words have been found, left over letters complete a statement about what frogs eat. This activity could be completed after a lesson using reference books to research what frog eat. Answer: ‘Frogs eat any live food they can swallow’. Extension Activities Get students to prepare a tank ready to house a frog for a week. Collect a frog from a local pond or wetland and have the frog in the class for the week. Make and record observations. Return the frog to the creek. Collect tadpoles from a creek. Make observations about the following: • Growth: How fast does a tadpole grow? How does its body change as it metamorphoses into a frog? How old will it be when it develops gils, arms, legs, and a tail? Record prediction and observations. Create a timeline. • Behavior: How does the tadpole behave throughout a day? Does its behavior change at different times? If you have more than one tadpole, can you observe a difference in behavior? Place a foreign object in the aquarium to see if it has an effect on the tadpoles behaviour. • Diet: How much does a. tadpole eat? Does it always eat the same thing? What happens to the food when it is swallowed? Fantastic Frogs and Terrible Toads Teacher Resource Kit 7 1.1 Frog Features Most people know that frogs are plumpish with broad heads, no tails and have long, strong back legs. Frogs have many more amazing features, some of which are listed below. See if you can match each description on the left with the name of the feature on the right. Frogs are different from other vertebrate in that they are members of the zoological class called Amphibia. This means they spend part of their life under water, breathing through their gills, and part on land, breathing with lungs. Slimy Skin Some frogs have adhesive disks on the tips of their fingers and toes which help them climb. On smooth surfaces these act like suction cups. Earthmovers Frogs absorb most of the moisture they need through their skin. Frogs also rely on getting extra oxygen (in addition to what they get from their lungs) from water by absorbing it through their skin. Leap Frog Frogs go slimy when they secrete mucus to keep their skin moist. Even with slimy skin, frogs need to stay wet. If there is no water to jump into, frogs can get moisture from dew or burrow underground. Feet for swimming Frogs can launch themselves over 20 times their own length using their big strong legs. Sticky Pads for Climbing Frogs that burrow into the sand to keep moist in the heat have stubby clawlike fingers that are adapted to digging. Amphibians Some frogs have webbing between their toes that make it easier for them to move through water.

Why are frogs important indicators of environmental health? What are the threats to frogs? How can we create a frog friendly habitat at home or school? Suggested Activities 2.1 Home Sweet Home The aim of this activity is to introduce the concept of a habitat (where an animal lives, feeds and breeds). Discuss the basic requirements for animals to survive (eg. shelter from predators/ extremes of temperature, access to food and water etc). 2.3 Environmental Health Fact Sheet This fact sheet outlines the concept of frogs as bio-indicators and provides useful background information for teachers. It is designed to be used with the ‘Environmental Health Crossword’ and is suitable as a handout for middle to upper primary students. 2.4 Environmental Health Crossword The crossword is a comprehension activity to be used after students have read the ‘Environmental Health Check Fact Sheet’. Please refer to Figure 1 for solution to crossword. H F A R B The ‘Home Sweet Home’ handout provides some basic facts about frog habitats. After reading the information, students draw and label the ideal habitat for ground dwelling frogs and tree frogs. Discuss with students what habitat characteristics they have drawn and why. I Instruct students that they will be creating a polluted habitat and a healthy habitat by pasting pictures on habitat posters. Provide each student (or group of students) with 1 healthy habitat and 1 polluted habitat poster (enlarged onto A3 paper) and a set of habitat characteristics. Instruct students to cut out pictures and paste them on the habitat posters. When completed, ask students to explain why they put certain pictures on each habitat.

Students are given the opportunity to state some of the pollution (rubbish in waterways, farm chemicals or pesticides, household chemicals such as soaps and detergents, oil spills, industrial waste etc) or other threats to frogs. Fantastic Frogs and Terrible Toads Teacher Resource Kit 15 2.0 Frogs and the Environment 2.6 Threats To Frogs Fact Sheet This fact sheet outlines the five major threats to frogs and provides useful background information for teachers. It is suitable as a handout for middle to upper primary students. After reading the fact sheet, students could develop a poster of ways to reduce threats to frogs (as suggested on the fact sheet). 2.7 Frog Friendly Environment The final activity in this section is to encourage students to create a frog friendly habitat at school or in their own backyard. The information sheet is designed to be discussed in class and used to guide the development of a frog habitat at school and/or home. Fantastic Frogs and Terrible Toads Teacher Resource Kit 16 2.1 Home Sweet Home Read the information below and draw the perfect home for the two frogs in the frame. Frogs can live almost anywhere and are found in most areas of Australia, even in arid and alpine areas. Frogs are most common in warm, moist tropics where there is plenty of fresh water. Streams, ponds, dams, swampy areas, creeks and flooded depressions all provide good habitat for frogs. Frogs are most active at night. During the day frogs rest under rocks and logs, in hollow trees, reeds, small shrubs or other debris, or climb trees or burrow themselves underground.

Frogs are a very good symbol of the health of our environment because they are so sensitive to environmental changes. The disappearance of many species of frogs is a sign that something is going wrong with the environment. A bio-indicator is a living (bio means life) creature that is indicating or telling you something about the area that it lives in. It can be something positive (good) or negative (bad). For example, having lots of frogs in an area tells you and scientists that the environment is healthy and complete for the frogs. If for some reason frogs are suddenly missing from an area or their population is declining (shrinking), then this is telling you that their environment is changing. Sometimes bio-indicators can be used to show us that the quality of the air we breathe or water we drink may not be of a high quality. Frogs are good bio-indicators because they: spend part of their life cycle on land and some in water. have a permeable skin (which allows substances to move relatively freely into its body). absorb and concentrate (make stronger) toxins in their fatty tissue. ‘Frogs are a symbol of the health of our environment’ In your own words explain what this means.

Fantastic Frogs and Terrible Toads Teacher Resource Kit 22 2.5 Threats to Frogs Like all living creature, frogs have natural predators – or enemies in the wild. There are lots of different predators that will eat frogs, such as snakes, lizards, birds, and other small mammals. Even in water; frogs, eggs and tadpoles might be eaten by fish or other frogs! But the largest enemy that frogs have isn't a predator, it is something humans have created. Can you guess what it is? If you need a hint, unscramble the letters below! L U O T L P N I O _ _ _ _ _ _ _ _ _ Draw or write some 3 types of pollution or other threats to frogs. Fantastic Frogs and Terrible Toads Teacher Resource Kit 23 2.6 Threats to Frogs Fact Sheet In recent years, scientists have become increasingly aware of a worldwide decline in the numbers of frogs. Frogs are certainly disappearing in Australia. Eight frog species have become extinct in the last 25 years, and several more are likely to become extinct in the near future. A range of factors are responsible for the decline in frog populations and include: destruction of natural habitat; increases in ultra-violet radiation (and the decrease of the Ozone layer); pollution; introduction of new predators or competitors into breeding areas; and diseases. Habitat destruction: Clearing large areas of native vegetation (for housing and agriculture), logging of forests, drainage of wetlands or allowing cattle to graze in them and other disturbances such as fire which reduces the amount of bush for frogs to shelter in, have left frogs with fewer areas to live and breed in. A frog's habitat is the environment in which it feeds, shelters and breeds and if it cannot find suitable habitat, it will die. So it's hardly surprising that habitat loss is one of the greatest threats to frogs. Depletion of our Ozone Layer: Increases in ultra-violet (UV) radiation as a result of the earth's thinning ozone layer may also have lethal affects on amphibians. Experiments in the laboratory and in the field have shown that UV radiation interferes with the development of eggs in some species. Increased UV levels may have even worse effects in higher elevations, where levels are already high. Pollution: Frogs are very vulnerable to chemicals and other contaminants in our waterways. Frogs generally spend part of their life-cycle in water, and their moist skins are especially sensitive to pollution. Frogs breath and drink through their skin, so pollution has a really devastating effects on them. This is particularly true in their developmental stages. In addition, chemicals can interfere with a frog's natural ability to fight off diseases and infection. Competition and Predators: Sometimes creatures that aren’t normally found in an area are introduced to that area. This can spell big trouble for local frogs. For example, Cane Toads were introduced to Queensland in 1935 and have spread through Queensland and into New South Wales and the Northern Territory. They have no natural predators here in Australia and in some areas have reached plague proportions. They prey on other frogs and compete with native frogs for food and habitat. Diseases: Scientists think the decline and disappearance of some frog species in Australia and overseas may be partly due to a disease caused by a fungus which attacks a frog's skin. Since frogs use their skin in respiration, this makes it difficult for the frog to breathe. The fungus also damages the nervous system, affecting the frog's behaviour and eventually killing them. Help! We need to stop frogs disappearing. Choose one of the threats to frogs and create a poster with tips about what people can do to reduce the threat!

How can the Frogwatch website be used to find out about frogs in the NT? Where can you learn more about frogs or see frogs? Suggested Activities 3.1 Flip the Frog (Memory Game and Activity Sheet) The aim of this activity to for students to realise that there are many different species of frogs, each with distinguishing features. Print two copies of each of the three pages of ‘Frog Cards’ using a colour printer and cut out each card. It is preferable that each page is printed onto card or laminated. Before instructing students to play ‘memory’ with the cards, it would be useful to talk to students about the different frogs on the page and get the students to talk about some of the differences between the frogs. Upper primary students can complete the activity sheet before playing ‘memory’. In small groups or individually, students are to compare and contrast the frogs and try and find a ‘distinguishing feature’ for each frog, which then recorded on the activity sheet. As students play memory, suggest that they read the name of the frog out-loud before turning them back over or collecting their pair. NB. The frog cards could be kept as a reference for other activities (such as discussing the difference between frogs and cane toads). 3.2 Frog Research Using the Frogwatch website, students are to research a frog and record their findings. On the website (www.frogwatch.org.au) click on ‘Frog Lists’. Choose a frog and click on its name. A table with ‘Details’ of the frog will appear. Look through each of the menus (‘Description’, ‘Distribution’, ‘Observations’, Images and Calls’). Record this information in each of the boxes on the worksheet. If time permits, students could create a poster by cutting and pasting the boxes on a larger sheet of paper and drawing/printing the frog. NB: Field guides could be also be used to find out specific information about the frog chosen. 3.3 Frog Calls The aim of this activity is to draw student’s attention to how frogs can be easily identified by their call and to develop skills that will improve their listening skills and ability to distinguish between different calls. After logging on to the Frogwatch website and following instructions provided, students are to listen to and record the phonetics of several frog calls on the activity sheet. NB This activity is suitable for upper primary school children. Computers with internet access are required. 3.4 Finding NT Frogs This activity provides information about locating frogs and can be used as a handout for students to take home to encourage them and their families to locate frogs in their local area. The advice would also assist teachers locate frogs on a school camp or specific frog-finding excursion.

You will learn so much more about frogs if you get the chance to see some live frogs. Here are some tips to help you get up close to some frog friends and find out more about them! Join FrogwatchNT. Frogwatch host regular cane toad/frog information sessions. They are usually advertised in the NT News or you can log on to www.frogwatch.org.au to find out if there are any meetings in your area. You can even register with Frogwatch and be notified of frog related events via email! Visit the Territory Wildlife Park. There is an amphibian display showcasing some of the Northern Territories frogs and tadpoles. It may be a good idea to check with them before your visit to find out what frogs are on display and if there are any talks scheduled. The Parks and Wildlife Service hold ‘Parks Alive’ events. These are advertised regularly in the NT News. Or you could contact them to find out when the next event is. Contact the Museum and Art Gallery of the Northern Territory to see what exciting displays they have in the Museum and Discovery Centre. Get out and find some frogs! Frogs are easy to find in the Top End, especially in the wet season… …all you need is a torch! Search around your house. Get a torch each and you can go ‘spotlighting’ for frogs at night. Can you hear the frogs calling? Are there any on your windows and walls catching insects? Are they visiting the pond or pool in your backyard? If there are 2 or 3 people, all point your torch beam at the spot you think the croaking is coming from. The point where all the light beams intersect is where the frog is hiding. Why not have a go. See if you can find that croaking frog using this method called ‘triangulation’. You could also go on a night expedition to a swamp, creeks or wetland one evening. These are exciting places to go spotlighting. Some possible locations include the Botanical Gardens, Knuckey Lagoons, Howard Springs and Fogg Dam. Or perhaps a large culvert beside the road! The following tips will help make finding frogs safe and enjoyable for you and the frogs! If you find a frog, it is best just to watch. Picking them up might harm them as they can absorb substances from our hands which will harm them. Leave any frogs where you found them. They are used to the environment they have been living in and they might not easily adjust to a new home! Make sure you read all warning signs about Crocodiles. Be careful near creeks and culverts, especially if there has been recent heavy rainfall. Be prepared for your visit. Make sure you cover-up with long trousers and a long sleeve shirt to avoid mosquitoes. If you are using insect repellent do not handle any frogs. It might poison them.

They were introduced from Central and Southern America. 3000 cane toads were released in sugar cane fields near Cairns in 1935. Cane toads were released to act as a biological control for sugar cane beetles. These beetles were stunting or killing the sugar cane in their grub stage by eating the roots of the plant. Cane toads did not eat the cane beetles as they were expected to. Within 10 years of their release, an insecticide was developed that effectively controlled the beetle problem. Cane toads can survive in temperatures between 5-40OC. When it is very hot or cold cane toads shelter by digging in the ground or hiding under logs. Cane toads are active at night and in the warmer months of the year. Cane toads can lose 50% of the water in their body before they will die of dehydration. This means toads tolerate dry conditions better than most frogs. Cane toads need pools of water to lay their eggs. In the tropics toads grow very quickly. By the age of one, they can produce 8000-35000 eggs each time they mate. Fantastic Frogs and Terrible Toads Teacher Resource Kit 39 4.5 Terrible Toad Crossword 1 1 2 3 4 5 2 6 7 3 4 8 5 6 Across 1.

Fantastic Frogs and Terrible Toads Teacher Resource Kit 40 4.6 Advancement of the CANE Toad For the past 60 years, cane toads have been expanding their territory in Australia, and are capable of colonising at least four of the mainland Australian states. Since their introduction in North Queensland, cane toads have spread rapidly, south into New South Wales, with one isolated community in Port Macquarie, and west into the Northern Territory. They have recently (July 2005) been sighted in the Botanical Gardens in Darwin. The cane toad's advance is only limited by environmental factors, such as the availability of water for breeding, tolerable temperatures, suitable shelter, and an abundance of food. The unlimited food source, suitable environment and low rates of predation allow for rapid reproduction and spread. The natural rate of spread of the Cane Toad is about 30-50 km/year in the Northern Territory and about 5 km/year in northern New South Wales. The range of the cane toad now includes coastal Queensland and associated inland areas, coastal northern New South Wales to just north of Lismore, coastal Northern Territory from the Queensland border to the south bank of the Roper River (Map 1). Map 1: Current distribution of Cane Toads (where they are found). On a separate sheet of paper, answer the following questions using the information on cane toad distribution and the toad map above. How many states are cane toads living in? How far do you think they might travel over the next 70 years? Draw your ideas on the map. Why do you think they have not moved into Victoria? Have you seen any toads in the Northern Territory?

What can be done to reduce toad numbers? Suggested Activities 5.1 Toad Free Zone The activity sheet contains a range of questions for students to answer using the ‘making your yard a toad free zone’ brochure. It will provide students with information they can then use to reduce the number of toads around their home. 5.2 Toad Trap Students use their knowledge about cane toads and follow a step by step process (outlined on the activity sheet) to design a cane toad trap. It might be useful for students to use the internet to research range of cane toad traps currently available (eg. www.frogwatch.org.au) to get some ideas or to use for comparison with their own design. 5.3 Toad Poster Starters The activity sheet lists facts relating to cane toads which are grouped under four key topics. Students could use the facts provided to construct a poster, PowerPoint slides or basic webpage, or as a basis for further research (which would be ideal for a group project). The students could undertake research using reference books, pamphlets and/or the internet. If findings are presented as a poster or on PowerPoint slides, this could be presented to the whole class. 5.4 The Cane Toad in the NT The aim of this activity is for students to be able to identify the impact of cane toads. After a class discussion, students are to record ‘impacts’ on their activity sheet. Middle and lower primary students could use the sheet to record ‘impacts’ using a brief description/explanation or a few words or by drawing a picture. Upper primary students could use the activity sheet to record findings from research on the impacts of toads (either using recent articles (in newspapers or research updates like Savannah Links) or the internet. The key impacts of toads include: • Native animals poisoned (eg. mammals such as quolls, reptiles such as crocodiles and monitors, fish etc) • Decline in the number of native animals (through poisoning and/or competition) • Toads prey on native animals • Compete with frogs for resources (toads breed more frequently, lay more eggs, eats more etc) • Frog numbers decline • Pets poisoned • Nuisance to humans 5.5 Mind Mapping Students use the image of a Death Adder that has been poisoned by a cane toad as the central theme for a mind mapping exercise. On completion, students could choose one of their ideas and explain it to the class or the person sitting next to them. 5.6 Toad Action Ideas to get involved in the community and start combating toads are provided in this information sheet.

How will fencing help stop Toads? 5. Draw a fence and label the specifications (material, height etc) that will make it suitable for keeping Toads out. Fantastic Frogs and Terrible Toads Teacher Resource Kit 45 5.1 Toad Free Zone Fantastic Frogs and Terrible Toads Teacher Resource Kit 46 5.2 Toad Poster Starters Why are cane toads a problem in Australia? • Toads compete with native animals for food and shelter (they take away food and shelter for native frogs, small mammals as there are usually lots of them) • Toads kill most types of native animals and pets as they are poisonous at all stages of their life cycle (eggs, tadpoles, toads). Most animals that try to eat the toad are poisoned and die quickly. • Toads eat native animals (they eat frogs, lizards, snakes, small mammals and eggs of ground dwelling birds) • Toads are free from predators/diseases in Australia. In their country of origin there are animals/diseases that limit cane toad numbers. • Toads can survive in almost any environment in Australia. • Toads can breed at any time in the year. Native frogs do not breed as often or lay as many eggs as cane toads. Frogs may be out-competed in physical numbers very quickly. • Toads live very happily in suburbia. They eat dog food as well as anything else! How can cane toad numbers be controlled? • Physical control. Collecting adults (mustering), pulling cane toad egg chains out of a water body and letting them dry on the bank in full sunshine. Trapping, toad proofing dams/ ponds. • Biological control. Several suggestions are being looked into. Dahl’s water frog (NT frog) eats cane toad tadpoles without dying. The lavender beetle is not eaten by native frogs. Cane toads love eating them and then die. Scientists are also looking at microbiological internal parasites that may slow down toad health and breeding. • Ecological control. These solutions have not yet been proven to be successful, but are worth mentioning. Scientists are looking at producing large numbers of sterile male toads to be released in the environment. Or genetically modifying cane toad egg production to only produce male cane toads. How do you handle cane toads? • Carefully! As little as possible. Only pick them up if it is really necessary. • With plastic gloves on. They secrete poison from the glands on the back of their neck that can be absorbed through your skin. Cane toad poison can kill people. • Keep them away from your face. • Keep your little brothers, sisters and pets away from cane toads. Tell your parents where to find the toad in your garden so they can get rid of it quickly. • Cats and dogs die from eating/mouthing cane toads. If a dog grabs a cane toad you should contact a vet for instructions. • Dispose of toads humanely in a plastic bag in the freezer for a day. Toads can be buried deeply as fertilizer in the garden or well wrapped in the rubbish (so animals at the tip don’t get to it before it decomposes). What can cane toads be used for? • Medicine. Scientists are still investigating. • Leather. There is a cane toad leather industry that makes wallets, key rings out of cane toad parts. • Scientific experiments. Freshly killed cane toads make excellent dissection material for school students. • Entertainment. Cane toad races for charity. Fantastic Frogs and Terrible Toads Teacher Resource Kit 47 5.3 Toad Trapping There are a few things we can do to reduce the numbers of cane toads. One way is to trap cane toads. Using the information you know about Cane Toads, design a trap that will stop them being a nuisance in your backyard!. STEP 1: To make a trap that really works you need to think about how toads move, what they’re attracted to etc. List what you know about toads here: STEP 2: List some of the material that could be used to make a trap. STEP 3: Write down how the toads will get in (eg. fall, jump, attracted) STEP 4: Explain how the toads will stay in the trap STEP 5: Draw the trap STEP 6: How will you know your trap is successfully reducing the impact of toads? Have a look at some of the commercially available traps at www.frogwatch.org.au How does yours compare?

Fantastic Frogs and Terrible Toads Teacher Resource Kit 50 5.6 TOAD ACTION Cane toads are becoming part of life in the Top End but you don’t just have to sit at home and let them take over. Here are some ideas to take into your community to help combat toads! Community Frog Night Organise a ‘Toad Muster’ You could host a community advertised ‘Frog and Toad Awareness Night’ Some ideas for the night could include: • Display all the work the children have completed on frogs and toads • Live frog and toad displays • Invite a guest speaker from Frogwatch, Parks and Wildlife, Territory Wildlife Park or NT Museum to come and give a talk and set up information. • Invite local nurseries to set up some of their water plants and pots as an attractive display and advertisement for their business. They could even sell plants on the night. • Invite a local wildlife group (such as RANA) to display/sell amphibian and frog friendly books. • Sell jelly frog cups, frog cupcakes and drinks to raise money for the school. • Frog colour-in competitions • Frog craft activities • Ideas presented in the section “Fantastic Frog Fun”. Select a cane toad infested site (perhaps even your own school or property), call all your friends, get together after dark and collect as many toads as you can. Think about feeding the mustering party with a BBQ and prizes for the ‘biggest toad’ and person who collects the most toads’ Walk Against Toads The school children could hold a walkathon to raise money to buy a cane toad trap for their school. Sponsorship could be per lap of the school or sporting ovals. Research Trapping Program on Cane Toad Numbers Trapping toads lowers the overall breeding population in our community. Toad numbers can be significantly lowered by a trapping program. With the trap bought from the proceeds of the “frog and toad awareness night”, you could start trapping toads at your school or a local wetland. You could have different classes trap for a month and collate the information on how many toads were caught, which was the best time of year to catch them, the number of males compared to females, the best place to locate the trap etc. There are many aspects that could be monitored and hypothesised about. Toadathon A “toadathon” could be generated for families to donate an amount for each toad caught in the trapping program mentioned above. Fantastic Frogs and Terrible Toads Teacher Resource Kit 51 6.0 Fantastic Frog Fun This section offers ideas for activities that can be used to compliment the delivery of Section 1 to lower primary classes. Activity ideas could be used to introduce the topic at frogs, as a reward at the conclusion of the program or as extra activities throughout the program. The activities would also be suitable if your class decides to host a ‘frog day’ to promote environmental awareness. Frog Fun Ideas • Frog dress-up day • Frog craft (refer to activity sheets) • Frog Facts quiz • Frog masks (see below) • Cooking with Frogs (see below) • Frog songs (see below) • Frog story-books (see below) Frog Songs Some popular frog songs include: • Frog jumped out of his pond one day • Der-glumph went the little green frog • Two little speckled frogs • Frog went walking on a summers day Frog story-books There are a range of popular children’s book with stories about frogs available from most school and public libraries. These include: • Tiddalik the Frog • ‘Lester and Clyde’ (series of books) • Picasso the Green Tree Frog Frog Masks One simple way to make a mask is to cut a paper plate in half. The flat side sits across the child’s cheek (with a small area cut out for the nose to make it more comfortable). The mask can be coloured or painted green, and egg-carton cups could be used above the eye-hole to make ‘bulging eye. Elastic can be stapled either side of the paper plate to hold the mask in place. Frog Cup Cakes Decorate pre-cooked cupcakes as follows: 1. Make a butter icing mix (adding food dye to make green icing). 2. Ice Cupcake. 3. Cut marshmallows in half lengthways and widthways (so you end up with a thin slice of marshmallow in a semicircle). 4. Push a dark coloured smartie onto each piece of marshmallow and position 2 on each iced cupcake to make ‘bulging eyes’. 5. Position a smartie on the cupcake for the mouth 6. Enjoy! NB: Cupcakes could be baked in class if time and resources permit. Frog in a Pond. The jelly will need to be made early in the day so it has time to set (alternatively they can be made the afternoon before and used the next day). 1. Each child is to receive one jelly cup with a Freddo Frog embedded in it. Each cup holds about 200ml of jelly, so you will need to calculate how much jelly you will need for your class. 2. Make up jelly in one lot following instructions. 3. Plastic cups should be placed on a tray or container that fits easily into the fridge. Pour 200mL of jelly into each cup. 4. Refrigerate jelly until it is cool, but not set. 5. Place Freddo Frogs in the jelly. 6. Jelly will set around the chocolate frogs. 7. When jelly is set, enjoy! Frog prizes You may like to include prizes for activities. You could use Freddo Frogs or Frog lollies or novelty frog toys (from Souvenir Shops). Fantastic Frogs and Terrible Toads Teacher Resource Kit 52 6.1 Origami Frog Make your own jumping frog using a piece of paper. All you need is: a piece of A4 paper or light card a pair of scissors a texta or crayon. 1. Make a square piece of paper by folding one corner of a piece of paper over to the adjacent side. 2. To finish making the square, cut the rectangle, overlapping the triangle. Open up the triangle and you have a square. 3. Fold the opposite sides together then unfold. Repeat folding the other sides. Open into a square again. 4. Fold each of the four corners to the centre point. 5. Fold each of the two top edges to the centre line. 6. Fold the triangle at the bottom upwards. 7. Fold each of the bottom two corners to the middle of the bottom edge. 8. Fold the bottom portion upwards (along the dotted line shown). 9. Fold the top half of the lower rectangle downwards toward yourself. This forms the frog's legs. 10. Give your frog a head by folding a small part of the upper point downwards. Draw two eyes. To make your frog jump, push down on the "X" and slide your finger away from the frog. Images and instructions sourced from http://www.enchantedlearning.com/crafts/origami/frog/.
