In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

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

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 plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
