Curated OER
Counting Animal Populations
Students learn how to count animal populations by the Mark and Recapture method. For this counting animal populations lesson plan, students begin by predicting amounts of different candies in a jar. Students then simulate using beans,...
Curated OER
Pollution Solutions
Students visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.
