In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this lesson, learners will practice graphing and statistically analyzing data.
