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

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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

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