Climate change poses the single largest, global threat to life on Earth, and yet the United States and our schools lag far behind the international community in educating and acting responsibly to mitigate the causes and effects of a warming planet. This online course for grades 3-7 teachers uses excellent platforms developed by NASA and the EPA to educate about the science of climate change in kid-friendly, interdisciplinary ways. Youthful graphics, games, lesson samples that cut across science, social studies and math, virtual expeditions to places where climate change is visible, CO2 footprint calculators and more make this a rich learning environment from which grades 3-7 teachers will develop their own units and themes—whether that’s oceans, birds, butterflies, fish, trees, fresh water supplies.  Many of your common science units can be modified with a climate change perspective (ie ocean life, plants and animals).
