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

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

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 activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
