How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

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

Earth Atmosphere Composition
Source Institutions
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.

Trees: Recorders of Climate Change
Source Institutions
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
Signs of Change: Studying Tree Rings
Source Institutions
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

Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

Automotive Emissions and the Greenhouse Effect
Source Institutions
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.

Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

Hot Stuff!: Investigation #3
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.

Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
