Science Living things and their habitats
�Last week you were beginning to sort animals into groups based on their physical characteristics. For this lesson, we will be looking at different classes of animals and grouping them.
Mammals Fish Reptiles Birds Amphibians Look at the above words. Can you remember these from previous years in school? Try and match the class of animal to the correct definition. � An animal that is warm-blooded, grows hair/fur, has a vertebra, breathes air and usually gives birth to live young � An animal that lays eggs, has feathers, wings, no teeth, is warm-blooded and has a vertebra. � An animal that is cold-blooded, breathes air, has skin covered in scales or bony plates. � An animal that is born and breathes in water when young but lives and breathes on land when grown and is cold-blooded. � An animal that is cold-blooded, has no limbs, a vertebra and lives wholly in water.
How did you do? � Mammal - An animal that is warm-blooded, grows hair/fur, has a vertebra, breathes air and usually gives birth to live young � Bird - An animal that lays eggs, has feathers, wings, no teeth, is warm-blooded and has a vertebra. � Reptile - An animal that is cold-blooded, breathes air, has skin covered in scales or bony plates. � Amphibian - An animal that is born and breathes in water when young but lives and breathes on land when grown and is cold-blooded. � Fish - An animal that is cold-blooded, has no limbs, a vertebra and lives wholly in water.
Vertebrates All of these classes of animals have vertebrae (backbones). Scientists use this information to help with how they group animals, particularly when discovering new species. We will look at invertebrates (animals with no backbone) in the next lesson.
Activity 1. Sort these 10 animals into the correct groups. For each animal, write why you have classified them in that group. Fox Kingfisher Bullfrog Grey Squirrel Clownfish Terrapin Mako Shark Newt Blue Tit Example – I think the fox is a ______ because it has ________ and ________. Gecko
Activity - Extension 2. Make a table of the 5 classes of animals. See how many animals you can correctly put into your table. Can you do 20 altogether? How about 30? 40? Challenge yourself – there are thousands of species out there! Fish Mammals Birds Reptiles Amphibians
