The Moon keeps one face toward us — so is it spinning, or frozen still?
You glance up at the Moon night after night and the same dark patches face you, the 'man in the Moon' never turns around to show its back. Works any clear evening, just look up.
Talk about it
- Tonight, look at the Moon and find the dark patches. They're in the same spot every night, the Moon never turns around, why not?
- Walk around a chair while always facing it. Notice you had to turn your whole body once to do it, that's exactly what the Moon does.
- Trick question for the table: is the Moon spinning, or standing still? The surprising answer is that it's spinning, just once per trip.
