Ms. Savage's 4th Grade Science Class
We are currently ending our unit of study on animal structures and their functions and how animals have internal and external structures that function to support survival, growth, behavior and reproduction. Students have learned how animals that live in different environments have to deal with different living conditions. These conditions can limit or control what characteristics animals that live in those environments can have to survive. Some animals have structures that help them move or eat. They also have structures that help them protect the insides of their bodies.
We have been reviewing for our upcoming unit test.
