The Earth's temperature is driven by angle of insolation. This is a fairly simply concept: the sun's light does not strike the surface at a right angle in most locations. Rather, it strikes it at an oblique angle, and it is this angle that causes different areas to experience different temperatures. This is a required topic for the New York Regents exam, and also in many earth science curricula. It is also a useful topic for astronomy classes, helping to explain climate mechanisms when modeling other planets.
It is a hands-on activity your kids will love, and includes questions and instructions to build the equipment that you can easily incorporate into your lesson. Accept no substitutes!
This is part of a series of lessons on Earth Science and Astronomy.
