Forgotten Genius

Forgotten Genius

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or physical change: mixing vinegar and metals (chemical), baking soda and vinegar (chemical), antacid tablets and water (chemical), cabbage juice indicator and acids and bases (chemical), sodium polyacrylate and water (physical), and cornstarch and water (physical). Connections are drawn to everyday chemical reactions in the "Changes in Everyday Life" handout.
