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.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

This video provides an overview of the research of the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on converting biomass to liquid fuels.

This video highlights a team of scientists who work on reconstructing the mass extinction that occurred 250 million years ago, the end of the Permian Period. This event wiped out the majority of life on our planet, resetting the evolution of life. Clues suggest that deadly bacteria might have set off a chemical chain reaction that poisoned the Permian seas and atmosphere.

This series of activities introduces students to the technologies of batteries and fuel cells. Activities include a mix of lectures, demonstrations, and lab activities.

This short, engaging video created by NASA presents a complex topic via a simple analogy. The idea of positive and negative feedback is demonstrated by Daisyworld - a world with black and white flowers growing on it.

This activity addresses naturally occurring climate change involving ENSO (El-NiÃo Southern Oscillation). In this activity, students play the role of a policy maker in Peru. First, they determine what sort of ENSO variation is occurring. Then, they must decide how to allocate Peru's resources to manage for possible weather-related problems.

In this activity students learn how Earth's energy balance is regulating climate. This activity is lesson 4 in the nine-lesson module Visualizing and Understanding the Science of Climate Change.

Hands-on laboratory activity that allows students to investigate the effects of distance and angle on the input of solar radiation at Earth's surface, the role played by albedo, the heat capacity of land and water, and how these cause the seasons. Students predict radiative heating based on simple geometry and experiment to test their hypotheses.

This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions.
