In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this online activity, learners find out whether they are smart enough to survive as a plant.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity, learners determine the necessary conditions for pea seed germination.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
