Create a Critter Collage
Students create a collage. In this animal classification instructional activity, students discuss why and how scientists classify animals. Students view pictures of different animals and decide which class each animal belongs to....
Curated OER
Create a New Animal
Students understand what physical adaptations are and how they help an animal to survive. In this adaptations instructional activity, students research four animals and then make an original animal that has adaptations to make them survive.
