In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this activity, children will let their imagination run wild as they design and build a new planet in the solar system.

Show your child the solar system and let them explore the stars and space by creating a painting. It's a fun and easy way capture your child's imagination.
