Engineers, scientists, and environmental groups around the globe are hard at work finding solutions to mitigate or halt global warming. One major goal of the curriculum described here, Save the Penguins, is to help students recognize that what we do at home can affect how penguins fare in the Southern Hemisphere. In addition, students learn how engineers are addressing global warming by designing energy-efficient materials. Further, they learn the science of heat transfer, design experiments to test materials, and then assume the role of engineer to design, create, and test their own energy-efficient dwellings.
