In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

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 hands-on botany activity, learners sprout vegetables in film canisters.

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.

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 plant seeds and watch them sprout and grow inside a CD case.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

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

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

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

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

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.

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

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.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
