Level 1: Wind and bubbles

Air and fluids · level 1 of 8 · rough age 5-6 (a guide for parents; anyone can start anywhere)

You cannot see air, but it is real stuff all around you. This first level shows how to tell it is there, what wind is, why bubbles hold air, and how wind pushes kites and sails. At the end you meet the thin, dusty air of Mars and its spinning dust devils.
