Description
Students will learn what types of items are and are not
biodegradable. This lesson complements Lesson 10 by
demonstrating that some types of trash will biodegrade
quickly and not become a problem in the environment,
while other types of trash stay around for a very long time.
Objectives
By the end of the activity, students will be able to list at least
two types of items that biodegrade and at least two that do
not.
