Goal: The shadow of the pencil will point to the time of day.
|Glue, paper plate, pencil for marking, ruler, wooden spool, and a long pencil.
|1. Glue the spool to the middle of the paper plate. Then stand the pencil in the hole in the spool, with the point up. Draw a small arrow on the edge of the plate.
2. Find a window, or a spot outdoors, where there is sunlight for a long time--all day, if possible. Put the paper plate there. Make sure the arrow points south.
Next, look at the time early in the morning. Use the ruler to draw a line down the shadow the pencil makes on the paper plate. Write the hour next to the line you traced. Do the same thing every hour. When you have a line for each hour of sunlight, your shadow clock is finished, 1 ... 12.
