The Cat in the Hat Knows a Lot About That!

Nick and Sally are trying to jump high enough to touch the Moon. However, gravity is — according to the Cat — "what goes up must come down"; to show them just what gravity is, that means a trip to the Moon. That's where they meet Astronaut Audrey who takes them for a space walk to learn all about gravity.

Sally and Nick are playing hide and seek, but Nick keeps sneezing. Good thing the Cat's friend Cluey Looey will be able to help them.

Nick and Sally want to keep playing, but it's getting dark. The Cat takes Nick and Sally to see Astronaut Audrey, who answers why does nighttime have to come. With a trip to her space station and a large model of the Solar System, the children learn that it's the Earth's spinning near the Sun that makes it night or day.
