I dont know how to make this inot a science fair project: A chemical that changes color in acids and alkalis is called an indicator. Red cabbage juice turns red when in acids, like vinegar, and green when in alkalis, like soap

Hi,

Check out this link to Science Buddies Project guide for a project on measuring pH with red cabbage juice:

Hopefully that will get you started with ideas. You can also read the Science Buddies Science Fair Project Guide for general help on how to do a project:
