Our Place in Space: Cosmic Rays
Grades:
35
Learning Goal(s):
Students will learn how the sun affects their school by measuring the temperature at different locations around the building in the fall, winter, and spring. They will learn how to measure solar energy and look for trends in temperature and solar power over the year. These trends will then be used to investigate how energy reaches Earth from the Sun.
