Slide 30 / 105 Review: Development Think back to the last unit. Do you remember the two different ways that animals can develop? Click in the boxes to test your knowledge. metamorphosis Slide 31 / 105 Direct Development Offspring have similar traits as the parents. They may have the same fur/hair, coloring, body features and behaviors. Look at the traits of the three offspring below. Which one is most similar to the adult? Draw an arrow to show your choice. direct development Slide 32 / 105 Direct Development Direct development produces offspring that are very similar to the adults. Slide 33 / 105 Direct Development How are the tiger cub and tiger parent similar? These similar traits were passed on to the bears from their parents. In other words, they inherited these traits. The tiger cub inherited these traits from the parent. Slide 34 / 105 Direct Development In what ways are you similar to your father? How about your mother? You inherited these traits from each of them! Slide 35 / 105 Offspring and Parents Parents that have certain traits do not have offspring with quite different traits. Goldie Hawn (Mother) Kate Hudson (Daughter) This horse mother gave birth to an offspring with pointy ears, a tail, tan-colored hair and hooves. It did not give birth to an offspring with feathers, claws and a beak.

Differences Return to Table of Contents Slide 51 / 105 Differences Different means not the same. It is the opposite of similar. A difference is something that is not the same. It is the opposite of similarity. Can you think of one similarity and one difference of an owl and a swan? Slide 52 / 105 Differences Animals can be very different. They may have differences in their size, shape, the way they get food, or defend themselves. Animals are especially different if they are different kinds of animals. What different traits do an elephant and a cat have? Do they have the same features? Do they live in the same environment? Do they defend themselves the same way?
Slide 53 / 105 Different Traits On the next slides, find different traits among the different animals.

Slide 66 / 105 Slide 67 / 105 Use pictures in books, magazines or internet to show similarities and differences between two animals. Complete the venn diagram. Label Animal 1 Animal 2 Slide 68 / 105 Slide 69 / 105 Siblings Do you have brothers and sisters? How about cousins? You all have the same parents or grandparents. Do you look exactly the same? Parent/Offspring Differences You probably have similarities but also many differences. Return to Table of Contents Slide 70 / 105 Siblings This is true for animals as well. Siblings, who have the same parents, can look quite different from each other. Slide 71 / 105 Everyone is Unique Siblings look different from each other and are also different from their parents. The traits of the mother and the traits of the father get chosen at random so that each offspring is completely unique! There will never be another you!
Slide 72 / 105 Direct Development Offspring who experience direct development look very similar to their parents. They also are different from their parents. They can look different and have different behaviors. Slide 73 / 105 Direct Development These baby birds have different characteristics from their parents. How does this young deer look different from his father? They may look different. They may sound different. They may act differently. Slide 74 / 105 Direct Development How are these offspring different from their parents? Slide 75 / 105 Metamorphosis Offspring who experience metamorphosis are very different from their parents! Let's compare a caterpillar to a butterfly. A caterpillar changes and grows through its life cycle into a butterfly. But caterpillars don't look like a butterfly, do they? How are they different? Slide 76 / 105 Metamorphosis A tadpole is different from a frog in many ways. Explain some differences. Slide 77 / 105 20 Baby animals never look different from their parents.
Slide 77 () / 105 20 Baby animals never look different from their parents. Slide 78 / 105 Plant Differences Plants also have similarities and differences from their parents. What is the big difference between this adult tomato plant and the seedling? Size Slide 79 / 105 Plant Differences Look at these two cactus plants. It takes a saguaro cactus 65 years to grow arms. Slide 80 / 105 Plant Differences Compare these offspring and parent plants. What difference do you notice in each picture? How are they the same? How are they different? Geranium Cucumber Dandelion Slide 81 / 105 Plant Differences Adults plants are able to produce flowers, seeds and fruit. Flowers, seeds and fruit are parts of a plant that are used in reproduction, to create new offspring. Seedlings are not able to produce these parts until they grow into adults. Slide 82 / 105 21 Adult plants have different features than their young seedlings.
Slide 82 () / 105 21 Adult plants have different features than their young seedlings. Slide 83 / 105 22 Do young plants have smaller stems and leaves?

Slide 86 / 105 Slide 87 / 105 Variation is Important Return to Table of Contents Slide 88 / 105 Variation When there are differences in one specific trait, it is called a variation. Slide 89 / 105 Variation What variation do you notice in these reindeer? These are all roses but they are different colors. There is variation in the color of the roses. The size/shape of the antlers is a variation. Slide 90 / 105 Variation Click below to watch a video about wild rabbits on Rabbit Island. How many variations can you find in the rabbits? Slide 91 / 105 Offspring Have Variations Offspring are similar to their parents in some ways and different from their parents in other ways. All offspring have variations from their parents. These seeds are all from the same maple tree. They are not identical. There are small variations. What do you see?
Slide 92 / 105 Offspring Have Variations These dogs have 7 puppies. The puppies look a little like both parents. They all have different variations. Slide 93 / 105 24 A variation is a difference in a specific trait. Slide 93 () / 105 24 A variation is a difference in a specific trait. Slide 94 / 105 25 Siblings are identical to each other and their parents. Slide 94 () / 105 25 Siblings are identical to each other and their parents. Slide 95 / 105 Variations and Survival Some variations help organisms to survive or to reproduce. Toucans have a lot of variation in beak size and color. Females decide who they will mate with based on these variations. The most colorful birds will reproduce and create offspring with colorful beaks.
Slide 96 / 105 Slide 97 / 105 Variations and Survival Remember these maple seeds? The biggest seed will fly the farthest and get to a sunny spot. There is more food in the big seeds, so these sprouts will survive the best. Variations and Survival Elk use their antlers for fighting wolves. The elk with the biggest antlers will survive a fight. Suppose that these three elk are born the same year. Which one will most likely survive a fight with wolves? Why? These small variations lead to better survival for the sprouts. Slide 98 / 105 Slide 99 / 105 Variations and Survival Variations and Survival This elk has the largest antlers and so would survive a wolf attack the best. The variation in antler size allowed him to survive. He can then reproduce and pass on this trait to his offspring. Rose plants with better protection will survive. These are all rose stems. Which do you think will protect the plant best? The plant that survives will be able to reproduce and pass on this trait to offspring. Slide 100 / 105 26 Variations help some organisms to survive. 26 Variations help some organisms to survive. Slide 100 () / 105
Slide 101 / 105 27 Flounder are a type of fish that bury in the sand. The fish that is able to blend into the surroundings the best can hide from other animals and survive. Which flounder has the color variation that will help it to survive the best? Slide 101 () / 105 27 Flounder are a type of fish that bury in the sand. The fish that is able to blend into the surroundings the best can hide from other animals and survive. Which flounder has the color variation that will help it to survive the best? A B A D B C D C D Slide 102 / 105 28 When individuals have variations that help them survive, Slide 102 () / 105 28 When individuals have variations that help them survive, A they do not live very long. B they do not have healthy offspring. C they get to live and produce more offspring. D they produce very few offspring. A they do not live very long. B they do not have healthy offspring. C C they get to live and produce more offspring. D they produce very few offspring. Slide 103 / 105 Slide 104 / 105
