Tracking the Sun

Materials Required:

1. A cardboard box
2. Thin poster board
3. Adhesive tape
4. Safety pin
5. A brick
6. A sunny day
7. Scissors
8. Unlined white paper
9. Clock
10. Pencil
11. An adult handling a penknife

When the sun seems to move across the sky everyday, it actually means that the earth turns on its axis. With the help of a special charting box, we can actually track this movement for a long period of time.

Take a cardboard of about 2 feet square and then remove the top flaps of it. Make the side with the opening facing you and place the box on its sides. Now at the top of the box, get an adult to cut a small hole for you, at about the middle of the box. Close up the hole, by placing a thin poster board over the hole and tape it to place. Now, very carefully make another hole in the center of the poster, with the help of your safety pin. Make sure that it passes through the hole that you have earlier made on the board.

Now on the other side of the board, tape a white paper on the bottom of it. Take the box out on a sunny day and point it towards the sun. In case the sun is not exactly overhead, please use a brick to tilt the box towards it. The paper will capture a small dot of sunlight on it. Use the pencil to mark the spot on the paper. Now, check a clock and write down the time next to the spot. Keep marking the spot where the sunlight hits every half-hour and write down the time. After quite some time, study the marks on the paper. While you may feel that you have marked the sun’s movement, due to the stagnant position of the sun, it was the earth’s movement that was actually tracked.
