On a sunny day, set a globe of the earth so that its axis points toward the North Star's position. Rotate the globe until the state in which you live is at the highest part of the globe and parallel to the ground. (The globe is now in the same position as is the earth, relative to the sun.)Locate where it is daytime and nighttime on the earth.

Place a small lump of modeling clay on the globe to represent the location of the school.

(Somebody whom we all know and love once deposited some
chewing gum onto the family globe, in the center of the Pacific Ocean and proclaimed it the Isle of Gumolia. Then, instead of doing something constructive like making a sundial, I wrote stories about things that happened there. It was fun, but they were all lies!)

Stand a toothpick straight up in the clay. The direction of the toothpick's shadow can be compared to that of a nearby flagpole, and you can see how your shadow moves throughout the day.
