Both bears have large paws with sharp claws. The two bears also have things in common that you cannot see in the picture. The mother and her cub hunt seals for food. They are both good swimmers. They also have an excellent sense of smell. _ offspring: the Parents and offspring of child or offshoot other organisms are also alike from a parent in many ways. They share 1 trait: an internal or external characteristic or feature certain features, or traits. Many of these traits help organisms survive in their environment. For example, a polar bear's fur helps it blend in with the snow and keep it warm in its cold habitat. Her sense of smell helps the mother bear find food when she is hunting. Why do parents and offspring have so many traits in common? How are these traits passed from one generation to the next? What features do organisms inherit from their parents? reproduction: Many living things inherit, or get, certain traits from their parents. the process by Inherited traits are passed from parent to offspring during which parents reproduction. Many external features of an organism are inherited. make offspring This is why different groups of organisms look so different. Think about types of birds. A flamingo inherits long legs and a long, curved neck from its parents. An eagle inherits sharp claws and a sharp, curved beak from its parents. Plants also pass on inherited traits such as leaf shape and size. For example, a maple leaf is wide. A fern leaf is long and narrow. These leaf shapes are inherited from the parent tree.

For example, some organisms, such as plants, inherit the ability to make their own food. Cats such as lions and tigers inherit the desire to hunt for food. House cats may hunt birds or mice, even though their owners give them pet food! Scientists think that even facial expressions are inherited. People who are born blind still naturally smile and frown, even without seeing other people do it. What features are learned behaviors? Not all features are passed from parent to offspring. Think of animals that can do tricks. Some dogs will sit, stay, or roll over if humans give them commands. Some dolphins can jump through rings. These behaviors did not come from the organisms' parents. These behaviors are learned. Learned behaviors are changes made by an organism in response to its environment. Parents or other adults can help teach their offspring learned behavior. For example, human parents often teach children certain manners, like sitting up straight or saying please. Children are not born with these manners. They have to learn them. The same is true about reading. Reading is not an inherited trait. Adults teach other humans to read. Look at the picture of the seal. What is one feature that the seal inherited from its parents? What is one feature that it learned? sti Many parts of an organism's physical appearance are inherited. However, some physical features are not inherited. For example, if an organism cuts or burns itself, it may develop a scar. This scar did not come from its parents. The same is true of a broken bone or dying your hair a different color. Those changes came from an interaction with the environment. This physical feature will not pass on to the next generation. Think of your own physical features. Do you have any that came from interactions with the environment? • 01'44, AcceIera:te Learning' © 2013-2014 Accelerate Learning - All Rights Reserved 88448 48484 48 4 Let's learn about inherited traits and learned behaviors in your class. 1.

Career Corner: Animal Breeders Why do some sheep produce more wool than others? Why do some dogs have floppy ears and some have pointed ears? In many cases, humans have changed the traits these animals have over time. Humans that work with animals' inherited traits are called animal breeders. Animal breeders change inherited traits by choosing which animals should reproduce. The breeders choose animals that have valuable traits. The goal is for these parents to pass on their valuable traits to their offspring. Sometimes breeders choose two parents with very different features in order to produce offspring with a unique mix of traits. Animal breeders work with many different types of animals. For example, they breed horses to produce offspring that are very fast and can run in horse races. Animal breeders also breed farm animals. They try to create offspring that produce more of the goods that humans use, such as milk and wool. Breeders also work with threatened species in zoos. They try to make sure the animals produce offspring. In this way, they try to help the species continue. lirOPA Accelerate F 1, 4 earning- © 2013-2014 Accelerate Learning -All Rights Reserved 3r What Do You Know?

Before the interview, brainstorm a list of questions to ask about inherited traits and learned behaviors. Recall that inherited traits are features passed genetically from parent to child and learned behaviors are actions that a child learns to do from experience or instruction. For example, students may ask about inherited traits like eye color, hair color, hair texture, or dimples. They may ask about learned behaviors such as playing sports or instruments. Students should ask the parent and child the same questions in order to compare their traits and behaviors. Make sure students do not ask about any issues that are too personal or sensitive. You may wish to share the questions beforehand with the relative you are interviewing. Here are some questions to discuss with students: • In what ways are the parent and child alike? Which of these features are inherited and which are learned? • Why might the parent and child share certain learned behaviors? • What traits might the child pass on to his or her offspring? Go with students to conduct the interview. Have students record their responses in a notebook. After the interview, help students complete a Venn diagram showing which features the parent and child share and which features they do not. ,T lkdk 2 Aul erxte © 2013-2014 Accelerate Learning - All Rights Reserved a r ing.

We are going to the aquarium!" 3 Lenny was surprised. "You mean, like the aquarium we have in my classroom?" 4 Lenny's dad chuckled. "No, that aquarium is just a small tank. The one I am talking about is a place where we can go to look at marine life. It is like a zoo for fish and other water animals." 5 Lenny loved animals, so as soon as breakfast was finished, he was ready to go. He and his dad walked to the city train and then rode to the aquarium. There, they saw many different types of animals, such as clownfish and seahorses. There was even a tank where Lenny could touch different animals and plants. 6 Lenny's favorite at the aquarium was the lionfish. It had beautiful stripes and pointy spines. 7 One of the marine biologists stopped when he saw Lenny staring into the lionfish tank. 8 "You really like that one, huh?" said the scientist. "It's my favorite, too. Hi, I'm Dan." 9 "Hi, Dan. I am Lenny. What does it eat?" asked Lenny. 10 "It eats other fish. Lionfish inherit a weapons system from their parents. See those spines? Those are full of venom, and the lionfish is a very efficient predator. It herds other fish into a corner, attacks, and then swallows them whole. In fact, a lionfish can eat 20 small fish in under 30 minutes." 11 "Whoa!" said Lenny. 12 "I, just got back from the Caribbean," said Dan. "I saw a lot of lionfish there. They are causing a lot of damage to the fish in the reef."

But the information card says that lionfish are from the Pacific Ocean and the Indian Ocean. They are both far away from the Caribbean." 14 "Good thinking," said Dan. "Do you have any idea how the lionfish could have ended up so far from their natural home? What's your hypothesis?" 15 "Maybe someone had a lionfish as a pet and didn't want it anymore. Maybe they just let it go in the water?" responded Lenny. 16 "You are close. We think the lionfish showed up in 1992. That is when Hurricane Andrew came through. We think that the hurricane damaged a private aquarium allowing six lionfish to be released into the sea." 17 "How could only six lionfish cause such a problem for the other fish?" said Lenny. 18 "Well," said Dan. "As I said, the lionfish has inherited traits that make it a very effective predator. The Caribbean reef fish were not used to lionfish. They had not learned behaviors that would allow them to escape the lionfish. So, those six lionfish multiplied into a big population. The problem has really grown!" 19 Lenny looked back at the lionfish drifting in the water. It was still beautiful, but now Lenny understood how dangerous a predator it could be. 20 10.4, 4 ccelerate A A Learning- © 2014- 2015 Accelerate Learnlng - An Rights Reserved READING SCIENCr 4.10B: Traits Organisms and Environments Why did Lenny's dad chuckle when Lenny said, "Like the aquarium we have in my classroom?"

He realized that Lenny thought all schools had aquariums. What do you think Dan probably does at his job? 2 A He sells tickets to the aquarium. He cleans the tanks at the aquarium. He studies marine life. We can't tell from the information in the story. Why is the lionfish such a successful predator in the Caribbean? 3 A It has spines that hold venom.

A True. Only six escaped from the aquarium during the hurricane. False. The lionfish in the Caribbean probably had offspring, who also had offspring, and so on. False. All of the lionfish are dead. This question cannot be answered with the information from the passage. 5 How do Lenny's feelings about the lionfish change over the course of the passage? A The lionfish is Lenny's favorite, but as he learns more about it, he understands it can also be dangerous. Lenny does not like the lionfish until he learns what a dangerous predator it can be. Lenny thinks the lionfish is neat, but he loves it even more when he realizes it is dangerous.

Background Information It's definitely a tough world out there, and all creatures have their own special way of protecting themselves from predators. All animals need to eat to survive but must also be aware of being eaten themselves. To protect themselves, animals have certain defense mechanisms that help them survive in the wild. Some of these are inherited traits and some of them are learned traits. Guiding Points Design a page for a book about animals with strange traits. 1. Choose one animal and identify its strange traits. 2. Determine if each of the traits are learned or inherited. 3. Describe how the traits are used in the wild. Fun Facts A horned lizard can shoot blood from its eyes from a distance of three feet. The hairy frog, or "horror frog," intentionally breaks its own bones to produce a set of cat-like claws. 4 A Accelerate Learning- Inherited means it is passed on from the parent to the offspring. For instance, a dart frog secretes a poisonous chemical from its skin. If it is eaten, it will cause its predator to get very sick. This makes it a very unwelcome meal. This type of trait is passed on from generation to generation. Some animals rely on learned traits or behaviors. Have you ever heard of "playing possum"? When a possum feels threatened or is frightened, it will roll over on its back and pretend to be dead. This will put off its attacker and give it a chance to get away. A possum is not born with this behavior. It has to learn it. There are many bizarre and strange defense mechanisms in the animal kingdom. For instance, a sea cucumber will squirt its insides out to defend itself and then grow a new stomach! © 2014 -2016 Accelerate Learning - All Rights Reserved 31. 4.10B: Traits Organisms and Environments PROJELLi -BASED [EARNING Student Checklist Presentation Content Organization • I included details covered in the Key Concepts as well as other important concepts I learned. • I organized my final presentation with an introduction, body, and conclusion. • My project has a neat appearance.
