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

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

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 (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity, learners explore sublimation by conducting experiments with dry ice.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

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 quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

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

Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

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

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

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