Please check your confirmation letter to ensure that the details for your excursion are correct. If there is a problem with your booking, please call the Bookings Office on 03 9392 4819. 2. Print the Explore-a-saurus exhibition map on page 5 and the exhibition description section on page 6 of the Teachers notes. These show the location of each exhibit, and describe the exhibits and the concepts that they demonstrate. 3. Copies of the exhibition map should be given to each group leader. Group leaders can then use the map to plan the order of exhibits they will see. 4. Ensure that group leaders are familiar with the Activities sections of the Education Kit. 5. Take some time in class to discuss your excursion to Scienceworks and assess student knowledge and understanding of the relevant topics. Research has shown that setting objectives for a museum visit is extremely important for students. It makes the purpose of the visit clear to them and assists their ability to focus and cooperate during the visit. Creating interest in the subject is vital to a successful and enjoyable visit to Scienceworks. What to bring to your visit to Explore-a-saurus A record of the actual number of students visiting on the day with which to inform staff upon arrival. A copy of the exhibition map on page 5 of the Teacher notes for each group leader. It is suggested that students do not bring bags to Scienceworks as there is limited storage space. A clipboard and pen can be used for working. A trolley is available for lunches in tubs or baskets. What to do during a visit to Explore-a-saurus During their visit, students can explore the activities in each exhibit. The Activities can assist group leaders in creating discussion with their group to review, reinforce or extend the ideas introduced in the exhibits. http://museumvictoria.com.au/scienceworks/education/ 4 Explore-a-saurus Teacher notes Exhibition map http://museumvictoria.com.au/scienceworks/education/ 5 Explore-a-saurus Teacher notes Explore-a-saurus exhibition description Might of a T. rex bite The jaws of some carnivorous dinosaurs could exert enormous bite pressure. Compare your physical strength to the force of a dinosaurs bite. Stand in the jaws of a Tyrannosaurus rex and push out to ‘resist the bite’. Are you strong enough to stop being eaten? Dinosaur hide and seek Like modern animals, the colouring of some dinosaurs may have acted as camouflage. This would have helped individuals blend in with their surroundings, either to hide from predators or stalk prey. By wearing different coloured and patterned cloaks, stand in front of various backdrops to see the effects of ‘disruptive’ and ‘concealing’ colouration. Ancient plants Some plants from the Mesozoic or ‘age of the dinosaurs’ are still exist today. Make a rubbing of the fossil plants and match them to their modern equivalents. Paintasaurus Research has provided us with some clues concerning the colouration of dinosaurs. This exhibit will explain how these conclusions were reached and enable visitors to colour in various dinosaurs throughout different environments. http://museumvictoria.com.au/scienceworks/education/ 6 Explore-a-saurus Teacher notes Insects trapped in time Palaeontologists can learn about the environment of dinosaurs by studying the animals and plants that lived with them. This includes looking at ancient tree resin, known as amber and observing insects trapped within it. This exhibit enables visitors to observe insects that are equivalent to those existing during the time of the dinosaurs. Six different specimens in amber can be viewed and compared under a magnifier. Toneasaurus Some duck-billed dinosaurs used complex chambers in their skulls to make noises, a bit like blowing air through a trumpet or tuba. Mimic the shapes of these cavities by joining tubes and replicate the sounds that some dinosaurs may have made. How did dinosaurs see? Some carnivorous dinosaurs had forward facing eyes and good binocular vision, while some herbivorous dinosaurs had laterallyfacing eyes and good peripheral vision. Experience the different vision of a carnivorous and herbivorous dinosaur. Munch-a-saurus Different dinosaurs had different diets. Some dinosaurs ate plants, while others ate fish or the flesh of other dinosaurs. Palaeontologist can tell what food dinosaurs ate by looking at their teeth, claws, stomachs and fossilised poo! Can you guess what these dinosaurs ate? http://museumvictoria.com.au/scienceworks/education/ 7 Explore-a-saurus Teacher notes Dinosaur eggs? Although some dinosaur eggs and rocks look similar, the presence of several features can easily distinguish fossilised eggs. There are three eggs and two rocks; can you tell which is which? Why did dinosaurs become extinct? Several theories exist regarding the extinction of non-avian dinosaurs. This exhibit demonstrates the possibility of extinction via collision of an asteroid with the Earth’s surface and the resultant dust cloud obscuring sun-light. Trackasaurus Some of the most famous dinosaur footprints come from Lark Quarry, near Winton, Queensland. Most of the tracks were made by small two-legged ornithopod dinosaurs that lived in Mid Cretaceous Period (approximately 90 million years ago). Palaeontologists first thought that one large set of footprints belonged to a meat-eating dinosaur that was possibly hunting the smaller ornithopods, resulting in a stampede. These large tracks are now thought to belong to a large plant-eating dinosaur, similar to Muttaburrasaurus. What do you think? Speedosaurus The speed of some dinosaurs can be calculated by measuring the distance between fossilised footprints and the height of dinosaur hips. This interactive enables visitors to estimate the speed of a duck-billed dinosaur by observing the height of relevant leg bones and the distance between footprints on the floor. http://museumvictoria.com.au/scienceworks/education/ 8 Explore-a-saurus Teacher notes Quizasaurus This game is for two players who adopt the name of the dinosaurs on the screen. Answer the quiz questions, based on information in the exhibition. The quiz aims to clarify misconceptions about dinosaurs and consolidate information from the exhibition. Robosaurus Make a metal model of a Tyrannosaurus skeleton move! This exhibit shows how the animatronic dinosaurs in Explore-a-saurus move through the use of compressed air. Jigasaurus This game invites players to select the correct bones and construct the skeletons of herbivorous and carnivorous dinosaurs. Choose to build a slow-moving, plant-eating Apatosaurus; a bone-crushing, meat-eating Tyrannosaurus or a bird-like Deinonychus. http://museumvictoria.com.au/scienceworks/education/ 9 Explore-a-saurus Teacher notes Dinosaurs on Show! - For more information on each dinosaur see Dinosaur Facts on page 16 • Apatosaurus (Apat-o-saw-russ) • Stegosaurus (Steg-o-saw-russ) • Tyrannosaurus (Tie-ran-o-saw-russ) http://museumvictoria.com.au/scienceworks/education/ 10 Explore-a-saurus Teacher notes • Triceratops (Try-ser-ah-tops) • Maiasaura (My-ah-sore-ah) • Muttaburrasaurus (Mut-ta-bar-ra-saw-russ) http://museumvictoria.com.au/scienceworks/education/ 11 Explore-a-saurus Teacher notes Victorian curriculum relevance Student activities and experiences in the Explore-a-saurus exhibition are relevant to Levels 1 – 4 of the Victorian Essential Learning Standards.

This is opposed to the splayed-legged stance of crocodiles and lizards. Non-avian dinosaurs (all dinosaurs except birds) lived between 230 and 65 million years ago. All dinosaurs are further grouped according to their particular hip-structure as follows: Saurischian or ‘lizard-hipped’ dinosaurs In the Saurischia, the hip bones are arranged like those of other reptiles, with one of the two bones below the hip joint pointing forwards (the pubis) and the other backwards (the ischium). Hip joint of a lizard-hipped saurischian. Saurischians include enormous plant-eating sauropods, like Apatosaurus and two-legged carnivorous theropods, such Tyrannosaurus rex and Allosaurus. Birds are also saurischians, as they evolved from small theropods. Ornithischian or ‘bird-hipped’ dinosaurs In the Ornithischia, both of the pubis and the ischium point backwards, although the pubis in latter forms projects both backwards and forwards. Other differences separating ornithischians from saurischians include the presence of a predentary, smaller antorbital fenestrae and wider hips for stability. Ornithischians include duck-billed hadrosaurs like Maiasaura; plated stegosaurs such as Stegosaurus; horned dinosaurs and their relatives, like Triceratops; domed-skulled dinosaurs like Pachycephalosaurus and small, fast-moving ornithopods like Hypsilophodon. All ornithischians are thought to have been plant-eaters. Hip joint of an early bird-hipped ornithischian. http://museumvictoria.com.au/scienceworks/education/ Hip joint of a late bird-hipped ornithischian. Note the extended pubis bone. 19 Explore-a-saurus Teacher notes Dinosaur controversies Many facts about dinosaurs are controversial. The Explore-a-saurus exhibition examines a number of issues such as: Did dinosaurs care for their young? What noises did they make? What was the colour of their skin? How fast could dinosaurs move? Explore-a-saurus also examines the extinction of non-avian dinosaurs (all dinosaurs except birds), which is expanded upon below. Why did non-avian dinosaurs become extinct? Nobody knows for sure. Many explanations have been proposed for the mass extinction event which occurred at the end of the Cretaceous Period, around 65 million years ago. Listed below are a number of reasonable explanations, as well as a few silly ones. Biological causes too large to hibernate mammals ate their eggs malformations of eggshells died of stupidity collapse of the food web too many predatory species parasites Terrestrial (non-biological) causes climate change (getting wetter, warmer, colder, drier) changes in atmospheric pressure floods earthquakes volcanic dust break up of super-continents by sea floor spreading spillage of frigid Arctic Ocean water into warm southern seas Extraterrestrial causes reversal of terrestrial magnetic field allowing flood of cosmic radiation shift of rotational poles sunspots supernovae meteorites and comets Miscellaneous causes entropy Noah's flood God's will killed by aliens http://museumvictoria.com.au/scienceworks/education/ Possible site of the meteorite impact which caused the end of the dinosaurs. 20 Explore-a-saurus Teacher notes Volcanoes, floods, earthquakes, disasters There were a large number of active volcanoes at the end of the Cretaceous, and this might have triggered global warming through the Greenhouse effect. This might have affected some of the dinosaurs, but probably not all, because dinosaurs occupied a wide variety of ecological niches. It remains a mystery why birds and some reptiles, such as crocodiles and tortoises survived while non-avian dinosaurs, pterosaurs and most marine retiles died out. Bombardment from space The rock layer that marks the end of the dinosaur era is peppered with a mysterious substance called iridium, a rare metal on Earth but very common in meteorites. This suggests that a huge asteroid, 10 to 15 kilometres across, hit the Earth, sending shock waves across the world and hurling massive dust clouds into the upper atmosphere, blocking out the sun for several months. No sunlight means no plants, which means no food for the plant-eating dinosaurs, and ultimately, no plant-eating dinosaurs for the meat-eating dinosaurs... so just about everybody goes hungry. Sounds like a crazy idea? There is a massive crater the size of Tasmania just off the Yucatan Peninsula in Central America, and it is just the right size and the right age to make scientists think it is the best explanation so far. But obviously some life survived because there is life on Earth today. Cross section of the Earth showing Tertiary, Fireball, Ejecta and Cretaceous layers Continental drift Scientists have discovered that the continents continue to move slowly. They now understand that, in the time of the dinosaurs, Australia was connected to Antarctica. This means that Australia was much further south than it is today and even though temperatures were warmer during that time, the southern parts of Australia would have endured long periods of darkness. Understanding the movement of continents over time, gives us clues about changes in weather and volcanic and earthquake action, both of which might have contributed to dinosaur extinction. The continents as we know them The geological and fossil record demonstrates that the crustal plates that make up the exposed surface of the Earth have been colliding and separating since the Earth cooled over four billion years ago. 650 million years ago Australia, Antarctica and India, moving south on one side of the planet, collided with Africa and South America moving south on the other side and formed a vast super continent named Gondwana. Two hundred million years later, Gondwana collided with the northern continents forming the supercontinent, Pangea. After more than 200 million years, various continental plates that formed Pangea tore apart again. Australia remained joined to Antarctica until the Eocene approx. 55-40 million years ago, when it separated and, attached to the southeast edge of the Indian oceanic plate, started its slow progress north. Twenty million years ago, Australia collided with Indonesia, pushing up the New Guinea highlands. http://museumvictoria.com.au/scienceworks/education/ 21 Explore-a-saurus Teacher notes Plate tectonics In the last 30 or 40 years geologists and oceanographers have amassed a vast body of evidence to support the theory of plate tectonics. It is now universally accepted that the crust of the Earth is in constant motion as 15 continental and ocean floor plates slide past, separate from, and collide with one another. Why do the plates move? We don't know with certainty but the most widely held hypothesis is that convection currents drive the plates. Warm fluids, including molten rock, tend to expand and rise as heat lowers their density. Plastic rocks (rocks which have been superheated) within the asthenosphere appear to rise towards the crust, spreading out and sinking back down as they cool. They are then rewarmed by heat generated by radioactive decay in the Earth's core, which continues the convection cycle. The slow, horizontal movement of the plastic rocks moves the relatively thin crustal rocks like rafts on a sea of hot tar. All the plates of the Earth's crust are joined to one another along their boundaries. When any plate moves it disturbs its neighbours. This can happen in one of three ways: shear, where plates slip past each other divergence, where plates separate convergence, where plates collide At shear zones a type of crustal break called a transform fault occurs. Here the rocks of two plates slide past each other with many a jerk and lurch, as the plates continually stick to one another and then break apart. Each break causes an earthquake. An example of a transform fault is the San Andreas of California where Baja California and south-western California are separating from the mainland, and moving north towards Alaska. Mid-oceanic ridges are plate boundaries where the basaltic ocean floor plates have moved apart. These divergence zones, or gaps, are constantly filled by the intrusion of basaltic lava from below. Sometimes enough lava erupts in these zones to form islands such as Iceland. The boundaries where plates meet are known as convergence zones. Generally an oceanic plate will plunge under a continental margin at a subduction zone. It is in these zones that the effect of convergence may cause uplifting and the formation of mountain ranges and volcanic island chains. It is also an area where earthquakes are generated. http://museumvictoria.com.au/scienceworks/education/ 22 Explore-a-saurus Teacher notes The Earth’s tectonic plates are constantly moving causing earthquakes, tidal waves and new islands to be formed. http://museumvictoria.com.au/scienceworks/education/ 23 Explore-a-saurus Teacher notes Fossilisation What is a fossil? The word fossil comes from the Latin fossilis, meaning 'dug up'. Fossils are the remains, moulds or traces of organisms that died a long time ago and were usually preserved in sedimentary rocks such as sandstones, silt stones and shales. Fossils provide evidence of past forms of life including; mosses, ferns, leaves, wood, pollens, shells, corals, crabs, worms, sea urchins, fish, amphibians, reptiles, dinosaurs, birds and mammals. About 250,000 different fossil species have been identified. How are fossils formed? For millions of years, life was only found in the oceans. The oldest fossils are therefore of marine organisms. When these animals died, their remains accumulated on the sea floor where they were buried by mud, sand or silt. When land animals or plants died, the soft parts usually decomposed or were eaten by scavengers. However, if the hard parts (bones, shells, wood) were covered by a sudden flood, or sand, or even volcanic ash, they might be preserved. Teeth are the hardest parts of an animal and were most likely to be preserved. Bone, wood and shell, although hard, have minute air spaces. When buried, water containing dissolved minerals may seep into these spaces and deposit minerals. Often, over millions of years, all the original bone or shell dissolves away leaving a complete mineral replacement embedded in the surrounding rock. The bones, wood and shell are then said to be petrified, or turned to stone. Rock is not the only medium that contains preserved fossils. Extinct insects have been found in fossil tree sap (amber). Animals that became trapped in natural tar pits have been beautifully preserved; mammoths and other animals that lived during the ice ages have been incorporated in ice, or frozen ground, so that flesh, hair and even stomach contents have been perfectly preserved. In some locations, scientists have also discovered impressions of skin. Sometimes, the entire animal decayed away but left a 'mould' that was then filled by sediments or minerals making a natural 'cast'. Similarly, footprints made in soft ground created moulds that were later filled, making casts. Where are fossils found? Fossils are generally rare, but can be found in road cuttings, quarries, cliff faces, river valleys and seashores - even in such places as building sites - fossil hunters (palaeontologists) can recognise sedimentary rocks that are likely to contain fossils of a particular period. Background research plays a large part in knowing where to look but luck has a major role as well. When a site has been identified as being a possible site for fossils and perhaps excavated with some success, similar rock formations may be sought in other localities. Some Victorian Sites Some of the better known localities in Victoria, where you can fossick for fossils (mainly invertebrates) include: Batesford quarry (near Geelong) but permission is required from the owners, Portland Cement. Buchan district The cliffs at Beaumaris beach but care needs to be taken as these cliffs are unstable. Fossil Beach, Mornington Wandong district Lilydale district Kilmore district Note that before removing fossils from excavation sites, permission must be acquired from the appropriate authorities. http://museumvictoria.com.au/scienceworks/education/ 24 Explore-a-saurus Teacher notes The plants that dinosaurs ate During the Triassic and Jurassic Periods, the dominant plants were non flowering forms, including cycads, ginkgoes, conifers, ferns, horsetails and quillworts. In the next large time period, the Cretaceous, flowering plants and grasses first appeared. Cycads Sometimes called 'living fossils' because they reached their peak in the Jurassic (199-145 million years ago). They received their name from a resemblance to palms. Unlike palms, however, cycads are cone bearing. They are found along the coastal areas and in isolated patches in central and south west Australia. Seeds of some species were eaten by Aboriginal people but are poisonous unless crushed and washed. Araucarias These ancient conifers are found scattered through the forests of eastern Australia. Araucarias appeared in the fossil records before dinosaurs but reached their peak in the Mesozoic. They are named after the South American Indians, Araucanos. The common names of the araucarias grown in parks and large gardens include the Hoop pine, Bunya bunya pine, Norfolk Island pine, Kauri and the South American monkey puzzle tree. Ferns Probably the most ancient plant group which still survives today. They first appear in the fossil records around 360 million years ago, in the Carboniferous period. While ferns are restricted to wet areas, they once dominated large areas of the Earth's forests and contributed much to the Earth's coal supplies. They can be propagated by vegetative means or sexually from spores. Ginkgoes Found in 270 million year old fossils. Curiously, the extensive family of ginkgoes has been reduced to just one member, the species, Ginkgo biloba. This species surprised scientists, who had thought it extinct, when it turned up in the gardens of some Chinese monasteries at the turn of the century. Female plants produce a rather quaint smelling orange coloured soft fruit. The fan shaped leaves have led people to refer to it as the Maidenhair Tree. http://museumvictoria.com.au/scienceworks/education/ 25 Explore-a-saurus Teacher notes Glossary Geological Periods Triassic (251-199 million years ago [m.y.a.]) so named because the strata that comprise sediments of this age can be divided into three distinct types. Jurassic (199-145 m.y.a.) named after the mountain range between France and Switzerland where rock strata of this age and type were first discovered. Cretaceous (145-65 m.y.a.) from the French word for chalk, cretace, which is found in rock strata of this age. Geological Eras Proterozoic means ‘earlier life’ (2500-542 m.y.a.) Palaeozoic means ‘old life’ (542-251 m.y.a.) Mesozoic means ‘middle life’ (251-65 m.y.a.) Cainozoic means ‘new life’ (65 m.y.a. - today) Biochemistry Endothermic - generating internal heat to moderate body temperature e.g. and mammals (commonly referred to as ‘warm-blooded’). Ectothermic - relying on the environment and behaviour to regulate body temperature. e.g. typical reptiles (commonly referred to as ‘cold-blooded’). modern birds Dinosaur classification Saurischia - lizard-hipped dinosaurs such as Apatosaurus, Tyrannosaurus rex, and the ancestors of modern birds. Ornithischia - bird-hipped dinosaurs such as Stegosaurus, Triceratops, Muttaburrasauru and Maiasaura. Dinosaur families Diplodcidae meaning ‘of the two-fold beams’. Hadrosauridae meaning ‘of the large reptiles’. Iguanodontidae meaning ‘of the iguana-toothed’. Stegosauridae meaning ‘of the roofed reptiles’. Tyrannosauridae meaning ‘of the tyrant reptiles’. Ceratopsidae meaning ‘of the horned-faces’. Dromaeosaurid meaning ‘running lizard’. Dinosaur The word dinosaur was coined in 1841 by Sir Richard Owen in specific reference to the only three known at the time -Megalosaurus, Iguanodon and Hylaeosaurus. The word derives from the Greek, deinos - terrible and sauros lizard. http://museumvictoria.com.au/scienceworks/education/ 26 Explore-a-saurus Teacher notes Resources Student resources Holtz, T. R.

For younger ages: Dino bones Cut out bones of dinosaur split-pin them together to form a dinosaur skeleton. http://pbskids.org/curiousgeorge/printables/dino.html Which Dinosaur is Different? A spot the difference in dinosaurs. Very young children just circle odd one out, as the students get older they can write the differences between dinosaurs, eg. Long neck, no horns. http://www.kidssoup.com/dinosaurs/a_dinodifferent.pdf For older ages: Students may make their own fossil casts (a simplified version could be made for younger years but would require a lot of assistance and be very time consuming) For all ages: What did you know before? What did you know after? This will assist teachers in discovering how beneficial excursion was. Students can also gage their own learning when they use this technique and can apply it to many topics of learning. Design your own dinosaur This activity can be adapted depending on age. Younger students may be required to draw a dinosaur, older students will need to provide a lot more information and give thought to their reasoning. ie: Create a name for your dinosaur using the table of names on page 37. What body shape and skin colour does the dinosaur have? Does it use camouflage, if so why? Is the animal an herbivore or carnivore? What sound does it make? How did it move? http://museumvictoria.com.au/scienceworks/education/ 28 Explore-a-saurus Teacher notes Activity 1: Making tracks and casts. What you need: some damp sand a long cardboard rectangle to circle the footprint a bag of dental plaster a large ice cream container for mixing a wooden spoon What to do: Either find a cooperative animal or make shoe or foot impressions in the sand. Circle the impression with the cardboard rectangle and secure with staples or paper clips. Mix the plaster according to the instructions on the bag. Pour and wait about 10 minutes for the plaster to harden. Remove the cardboard circle. The plaster cast becomes the negative impression of the footprint. To make a positive version, one needs to press the negative impression into a soft material like clay. Circle the clay impression and repeat the plaster pour. Questions: 1. Who else makes plaster impressions of footprints or tracks? 2. If there was not any plaster to fill an animal’s footprint, what must have fallen into the impression to preserve it? Extension idea: Go for a walk around the school or home and look for impressions left in concrete footpaths. What stories can the students generate from these marks? Presumably some marks are graffiti like, while animals or pedestrians may inadvertently leave others. http://museumvictoria.com.au/scienceworks/education/ 29 Explore-a-saurus Teacher notes Activity 2: A question of scale. How to increase the scale of a drawing using a grid. What you need: A drawing of a dinosaur ruler pencil eraser A3 paper for the enlargement What to do: You are going to scale up a drawing of a dinosaur using the grid method. Draw a 10 by 10 grid over your dinosaur. Decide on the ratio of enlargement for the dinosaur, would you like to scale the drawing up by a factor of two, four or ten? On the larger paper, construct the next 10 by 10 grid according to the ratio you have chosen. Transfer the elements of each square in the original photocopy to the larger grid, square by square. This is a standard method used by artists and designers to enlarge or compress the size of things they want to draw. Extension questions: Why does the surface area of an animal increase at the square of the enlargement but the mass of the animal increase at the cube of the enlargement? Palaeontologists have observed that the length of a dinosaur is often about 5 times the length of its femur or thighbone. What is the relationship to human height and femur length? Palaeontologists have also connected foot length to height, as well as stride length. Try graphing the foot length of students in your class with their heights. Was there a strong connection between the length of student’s feet and their height? http://museumvictoria.com.au/scienceworks/education/ 30 Explore-a-saurus Teacher notes Activity 3: A question of scale. What happens to weight when size doubles. What you need: models of dinosaurs plasticene set of kitchen scales What to do: When dinosaurs grew in size their weight increased at an exponential rate. This means that if the dinosaur doubled its size or dimensions, the weight increased at a cube rate, that is 2 x 2 x 2 or by a factor of 8. To test this mathematical modelling of weight increase, you will need to make a plasticene model of a dinosaur and compare its weight with a model which has been doubled in length, height and width, that is, twice as big in every dimension. • • • • Make a small plasticene model of a dinosaur, for convenience sake try to make its height and length a convenient whole number of centimeters. Weigh the plasticene model. To double the size of the original plasticene model, all components have to be twice as big. Weigh the larger plasticene model. dinosaur 1 size Weight estimate weight grams 2 Twice dino #1 3 Thrice dino #1 http://museumvictoria.com.au/scienceworks/education/ 31 Explore-a-saurus Teacher notes Activity 4: A question of scale again. Calculating the weight of a dinosaur. What you need: model dinosaurs bucket of water cotton thread a tray to catch the water which overflows from the bucket a one litre graduated jug What to do: You are going to work out the approximate weight of the dinosaur from the model. Fill the bucket of water to the very brim, this is important as you are going to immerse the model dinosaur and calculate the volume of the model dinosaur. • • • • • • Suspend the model dinosaur from the cotton thread Immerse the model into the full bucket, ensuring you catch all the water, which overflows. Measure the volume of the water displaced by the model in the graduated jug in millilitres. Calculate the weight of the displaced water, the millilitres of water displaced equals the weight of the water in grams. To calculate the weight of the original dinosaur, multiply the weight of the water displaced by the model, by the scale cubed. For example, if the model is one tenth scale and the water displaced was 400 grams or 0.4 kg. Therefore, the approximate weight of the original dinosaur would be 4 x 10 x 10 x 10 kilograms = 400 kg. http://museumvictoria.com.au/scienceworks/education/ 32 Explore-a-saurus Teacher notes Rich Learning Tasks If teachers wish their students to undertake a Rich Learning Task, they should be aware that the tasks require discussion and preparation prior to the visit to Scienceworks. This will determine which exhibits students should see. Additional work may be required to be completed when back at school, particularly if students are required to make a presentation based on the Rich Learning Task for assessment purposes. Teachers will need to decide or negotiate; Whether students will be working in groups or individually. If students are to work in groups, then teams of three to four students are best to avoid crowding around each exhibit. The Rich Learning Task resources include a team agreement/contract to assist students to explore how they can work within their teams. Teams will also need to discuss how they will collect the images/information they require for their task, during their visit. Which one or more Rich Learning Tasks are suitable for students within the class to complete? All students may complete the same activity or they may be allowed to choose one for themselves. These may be adapted to ensure that they are appropriate for each individual or group of students. The activities have flexibility to cater for individual needs and interests. A particular VELS domain could also be selected as the focus of the visit. Whether students are allowed bring digital cameras or mobile phones so they can document their experience in the exhibition for later use. Students may also be allowed to use the voice recording function on their mobile phone or mp3 player to record their observations. How students will move through the exhibition and what they might see. Taking their particular Rich Learning Task into consideration, each team should map out which exhibits may be of most relevance to completing their task, on their copy of the exhibition map. The exhibit descriptions on page 6 will help them to identify these. During their visit, they must try to get through as many of the relevant exhibits as possible and gather the information or images they need to be able to complete their task back at school. If an exhibit is ‘busy’ it is important that they try to find another one that they can use rather than just waiting for one to become free. The order in which students work through the exhibits is not important, so encourage the class to start at different places within the exhibition. Each student or team will need to decide what format their final presentation will take. For some suggestions see page 42. Rich Learning Task resources Assessment rubrics, a work log, and a team agreement/contract are included in this kit as separate PDF documents to assist teachers to assess and promote student learning. Refer to the ‘Resource’ section on the Explore-a-saurus web page. Decide which of these resources are relevant to your students’ needs and the curriculum areas you wish to cover before your visit. Spend some time in class with your students discussing the requirements associated with these materials. http://museumvictoria.com.au/scienceworks/education/ 33 Explore-a-saurus Teacher notes Create your own rubrics with your students A very useful educational activity is to allow students to develop their own rubrics for a particular task. This allows them to identify the key features or skills relevant to the task and promotes self-reflection on their work habits and skill levels. You could start this process by asking students to consider the following: What are some of the key features that you would expect to find in a really good presentation? List these. Discuss your answers with your team and together come up with a final list. Discuss your ideas with the rest of the class. Key features of Rich Learning Tasks could include: working with others organisational skills self-reflection written content visual or verbal content You may also want students to focus on particular VELS domains and dimensions. You could prepare a template (‘Make your own rubric’) and ask students to write brief statements that describe observations to be made for each feature. Use Rubrics 1 – 3 as a guide. Remember that whatever choices are made, they need to be meaningful to students and able to be measured or clearly observed. Working in teams If your students are working in teams, you may find that the sample ‘Team agreement /contract’ provided is a useful resource. By allowing all members of the team to work on the contract, students will develop an understanding of how they are responsible for working together. Developing organisational skills If you are encouraging students to enhance their organisational skills while working on the activities provided, you may find that the sample ‘Work log’ is useful. If you wish to explore the world of electronic mind mapping with your class, you may wish to consider using Bubbl.us which is a simple, free web application that allows your students to brainstorm online. The program allows you to create mind maps online and students are able to share their work. For more details go to: http://www.bubbl.us/ A similar program that has a free version is Mindmeister. For more details go to: http://www.mindmeister.com/home/premium http://museumvictoria.com.au/scienceworks/education/ 34 Explore-a-saurus Teacher notes Task 1: Design a theme park for dinosaurs. There are many things that need to be considered in the design of a theme park. Not only do you need to think about the rides that will be offered, but also what facilities you will need to provide. Some things you will need to decide on are: What menus will the food stalls offer? How will you design the toilets? What are the height and weight limits for each ride? Have you designed the layout for easy access for all sizes of dinosaurs? Do you need a locker space? How big do the lockers need to be? There are other things you will need to consider in your design. What allowances do you need to make for different dinosaurs? Have you catered for both carnivores and herbivores? The task: 1. Design the layout of the park, placing rides, shops and facilities at convenient locations. Be prepared to justify your design and placement of facilities. 2. Make a sketch of your layout, or a model of your park. 3. Present your ideas to the rest of your class. http://museumvictoria.com.au/scienceworks/education/ 35 Explore-a-saurus Teacher notes Task 2: Could dinosaurs rule the Earth? It is thought that the dinosaurs died out after the Earth was hit by an asteroid. If the dinosaurs didn’t die out and were still alive today, how would they have evolved? Would they be the dominant species on Earth? What would their relationship be with other life forms on the planet? Would humans still have evolved? Task 3: What if? An asteroid did hit the Earth and the resulting dust cloud meant that the planet had six months of darkness. What would be the effect on the food chain? Hint: look at plants as well as animals in the food chain. What would survive? How would the different species survive and would they thrive? Task 4: How does a palaeontologist know what a dinosaur looked like and how it behaved? What evidence does a palaeontologist use to decide what a particular dinosaur looked like, how it moved, what it ate? What evidence is presented in the exhibition? Is there anything that is missing? How accurate are their ideas, have they changed over time as new discoveries are made? http://museumvictoria.com.au/scienceworks/education/ 36 Explore-a-saurus Teacher notes Dinosaur names Name
