- What value do these habitats have?
Plant/Animal List (5 minutes)
- Each student will receive a list of plants and animals that are to be placed in the proper habitat.
- The class will do the first one together with the teacher.
- Each student will then individually proceed to place the rest of their list in the correct habitat.

Activity (5 minutes)
- Students will stand in a circle.
- One student will hold the end of a ball of yarn while tossing it to another student in the circle.
- Each student will hold a section of the yarn while tossing it to another student.
- Repeat this process until each student is holding a section of the yarn and the circle is crisscrossed randomly with yarn.
- The yarn will go continuously across and around the circle.
- Have one student release his section of yarn.
- Result: All of the remaining students must adjust to tighten the strands of yarn.
- Repeat with second student.
- Point out that this is similar to the interdependence of plants and animals and their habitats.
- Each component affects the other components.
Read Biodiversity Booklet (15 minutes)
- Students will choose a habitat.
- They must remove one component and then write down all of the consequences that result from the removal of the component.
