# Global Energy Balance

## Activities

Distribution of Solar Energy. NOAA. Grades 6-12. http://www.esrl.noaa.gov/gmd/education/lesson_plans/Distribution%20of%20Solar%20Energy.pdf. In this activity, students will describe and illustrate the distribution of solar energy received by the Earth.

Insolation and the Earth’s Surface. NOAA. Grades 6-12. http://www.esrl.noaa.gov/gmd/infodata/lesson_plans/Insolation%20and%20the%20Earth's%20Surface.pdf. In this activity, students will create and use a small scale model to observe the factors affecting both energy absorption and emission in Earth materials.

The Hydrologic Cycle. NOAA. Grades 6-12. http://www.esrl.noaa.gov/gmd/education/lesson_plans/The%20Hydrologic%20Cycle.pdf. In this activity, students will model the relationship between the states of matter (specifically water) and heat energy. Students will also simulate the Earth’s water cycle and evaluate/ quantify the exchange of water within the Earth’s hydrologic cycle.

## Videos

Striking a Solar Balance. NASA. Grades 9-12. http://www.youtube.com/watch?v=Pz0JBSKRhf0. This short video by NASA describes Earth’s solar energy budget and how it relates to climate change.

## General Web Resources

Climate and Earth’s Energy Budget. NASA Earth Observatory. http://earthobservatory.nasa.gov/Features/EnergyBalance/page1.php. This article by NASA provides an excellent explanation of the various components of Earth’s energy budget. Images, graphs, and diagrams provide visual support to the text.

Earth’s Radiation Budget Facts. NASA. http://science-edu.larc.nasa.gov/EDDOCS/radiation_facts.html. Bulleted fact sheet and diagram summarizing Earth’s energy budget.

Biogeochemical Cycles. Ritter, Michael E. The Physical Environment: an Introduction to Physical Geography. (2006). http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/earth_system/biogeochemical_cycles.html. This section discusses biogeochemical cycles, including the hydrologic, nitrogen, oxygen, and carbon cycles. Site also provides access to background information and a description of how these cycles are related to climate change.
