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

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

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 test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity, learners discover if carbon dioxide has an effect on temperature.

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

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

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 activity, learners will plot the distribution of various oozes using information from sediment maps.

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