Learning Goal(s):
Students will make observations to determine the effect of sunlight on Earth’s surface. Students will plan and conduct investigations to determine whether structures made with various materials will keep objects cool when placed in a beam of light. Students will analyze data from tests of two objects designed to solve the same problem in order to compare the strengths and weaknesses of how each performs. Students will analyze data obtained from testing different materials to determine which materials have the properties that are best suited for keeping an object cool. Students will test if solar panels and solar energy can help cool down their structure.
