In science we investigated this question. We know our own shadows move when we move. We figured out how, using a flashlight, we could make a fixed object's shadow move to be different sizes and in different positions. We learned this happened by moving the light source around. Students made the connection that the sun is a light that moves (or seems to move compared to us) and therefore causes different shadows. This activity will be a grounding activity to refer back to as we discuss why the moon looks different at different times.
