This lesson focuses on the importance of ocean exploration as a way to learn how to capture, control, and distribute renewable ocean energy resources. Students begin by identifying ways the ocean can generate energy and then research one ocean energy source using the Internet. Finally, students build a Micro-Hydro Electric Generator.
In this activity, which comes at the beginning of a 40-day sequence of activities in an energy module, students observe the transfer of solar energy to different appliances with a solar cell and investigate the effect of using different solar sources to supply energy to appliances.
This short video clip summarizes NOAA's annual State of the Climate Report for 2009. It presents a comprehensive summary of Earth's climate in 2009 and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.
In this activity students trace the sources of their electricity, heating and cooling, and other components of their energy use though the use of their family's utility bills and information from utility and government websites.
This is a polar map of permafrost extent in the Northern Hemisphere. A sidebar explains how permafrost, as it forms and later thaws, serves as both a sink and source for carbon to the atmosphere. Related multimedia is a slideshow of permafrost scientists from U. of Alaska, Fairbanks, collecting permafrost data in the field.
This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.
