Seasons Lab

.
Summary:

After yesterday’s lecture on seasons, today it was time to apply what we learned. Students completed the Seasons Lab (posted below). They used a flashlight to simulate the sun and used graph paper to simulate Earth’s surface. As the angle of the graph paper was increased, as in winter, the light became more and more spread out. Of course, this is what causes the winter drop in temperature; the sun’s energy is spread out over a large area, so it feels weaker. Students traced the area that was illuminated by the flashlight, counted up the number of squares that were lit up, and then calculated the number of watts per square. They completed the post-lab below for homework.
