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

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

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