Science Buddies: Cold Room? Heat It Up With a Homemade Solar Air Heater

Humans need food, water, and warm shelter to survive. But a lot of humans depend on fossil fuels to supply gas and electricity to heat our homes. But burning fossil fuels to create energy is harmful to the environment. In this science fair project, you will build a solar air heater as an attempt to provide free heat to homes without burning fossil fuels.
