Abstract:: Students test whether the color of a material affects how much heat it absorbs. Students will place an ice cube in a box made of colored paper (one box per color; white, yellow, red and black), which they will place in the sun. The students will make prediction as to which color will melt the ice cube first. They will record the order and time required for the ice cubes to melt.

Let the Sun Shine!

Abstract:: Students learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity. Students investigate the thermal energy storage capacities of test materials. They learn about radiation and convection as they build a model solar water heater and determine how much it can heat water in a given amount of time. In another activity, students build and compare the performance of four solar cooker designs. In an associated literacy activity, students investigate how people live "off the grid" using solar power.
