Question 2 True / False
A whale is a fish because it lives in the ocean.
TTrue
FFalse
Answer: False
Whales live in the ocean, but they are mammals, not fish. Whales breathe air with lungs (they come to the surface to breathe), they are warm-blooded, they have a little bit of hair, and mother whales feed milk to their babies. Fish breathe through gills and have scales.
Question 3 Short Answer
How can you tell if an animal is an insect?
Think about your answer, then reveal below.
Model answer: An insect has six legs and a body divided into three parts (head, middle, and back). Most insects also have wings.
The easiest way to identify an insect is to count its legs — insects always have exactly six. Their body has three sections: the head, the thorax (middle), and the abdomen (back). Spiders have eight legs, so they are not insects.
