This unit is meant to be taught after second graders have learned about plants and the basic needs of plants. In this unit students will explore how plants and animals rely on each other for survival. Through concrete, hands-on, and multimedia activities, students learn about food chains, basic needs, and what is required for survival in different habitats. As a culminating activity students will choose a habitat and a natural or man-made event that occurs in that habitat. Students will then draw a picture showing what the habitat looks like before the event and make predictions about how the habitat will change, specifically how the animals will react to the change. Next, students will draw a picture showing the habitat after the event and write a newspaper article to inform the public of the changes.
