8A20.05 - Earth's Seasons
Place the Earth globe with the solar cell into the area lighted by the slide projector. As you tilt the Earth globe, the readings on the multimeter will change simulating the amount of sunlight received as the Earth season's change through out the year.
The Earth-Moon-Sun system will show the changing tilt of the Earth in relation to the sun as the Earth rotates around the Sun.
