Solar Water Heater

In this project, students make a Solar Water Heater for the purpose of Sun Tea. First they take a vessel that can hold at least one liter, mark off where one liter of water would be, then outfit their vessel to collect and retain the sun's energy. After making their vessel, they take data to show that their's is more efficient than a mason jar. As an extension, they could find a function that fits their data.
