Color-Changing Chemistry
Mix up some safe science and watch colors change like magic!
Marie Curie was a chemist, too. You can use a natural indicator to test how some things are acids and others are bases — with beautiful results!
What You Will Need:
Red cabbage
Water and a pot or microwave
Clear cups or glasses
Lemon juice, baking soda, vinegar, soap, etc.
Strainer and spoon
Step-by-Step Instructions:
Boil chopped cabbage in water to make purple juice. Let it cool.
Pour the purple liquid into clear cups.
Add different liquids to each cup and watch what happens!
Use a spoon to stir gently.
Write down what color each turns — pink for acid, green for base.
What to Look For:
Which items changed the cabbage juice color the most?
What color means something is an acid or a base?
How might Marie Curie have tested unknown materials?
Curie Fun Fact!
Marie Curie used chemical separation to find radium — drop by drop!
Safety Tip:
Use only safe kitchen items and ask an adult to help with boiling water.
