The Moon That Seems to Follow
A nearby tree can seem to race past. The Moon can seem to come with you. This short experience turns that familiar puzzle into a way to notice viewpoint and distance.
Begin with a guess, compare near and far objects, then test what appears to move when you do.
IgniteBegin with the strange part
Give the puzzle room before you explain it.
Offer one puzzle. Leave room for a guess.
When you can see the Moon from a safe place, ask, "If we walked to the other side of this street, would the Moon move past that tree?" Wait for a guess.
Another way to begin
If your child has noticed the Moon from a car, ask, "Why do nearby things seem to rush past while the Moon seems to come along?" Let the question stay open.
No Moon needed. Look through a window at a nearby object and a faraway building. Ask, "Which one would change place more if we took three big steps sideways?"
