In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
