There is nothing that makes a kid feel more like a real scientist than making a red cabbage indicator and using it to determine whether household solutions are acidic or basic. Experimenting with a homemade pH indicator is a fantastic hands-on way to introduce children to real world acid/base chemistry. It is one of our favorite kitchen science experiments!
What is a Red Cabbage pH Indicator?
Indicators are chemical compounds that change color when added to a solution to show whether the solution is neutral, acidic, or basic. Red cabbage contains a chemical called anthocyanin that makes a very colorful (and safe!) homemade indicator.
The kids LOVE watching the color change right before their eyes!
