Sundials

After a brief lesson about shadows, the compass rose, and the history and parts of a sundial, fourth grade scientists made a make and take sundial. Love the way this activity connects with angles. The toothpick is the gnomon. We investigated how a sundial works with a flashlight. The sundial must point to the North. Leave the sundial outside or in a sunny window to watch the passage of time.
