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 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 activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
