Shadows

 On a nice sunny day we can make shadows with our bodies and our hands.

This will only work if the sun is behind us.  We could make our shadows grow tall and shrink small and we could make scary Gruffalo shapes.

We talked about whether it is the sun that moves during each day or whether it is the earth that moves around the sun.  Which do you think is correct? (Answer: The earth moves but the sun doesn't)
