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, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

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 online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

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

This lesson plan enables learners to explore the differences between weather and climate.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

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

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

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

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

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

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

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.

Learners will understand the relationship between climate change and sea-level rise.

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 explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

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

This activity has three story puzzles learners can solve to learn about life in the Arctic.
