STEM-ing At Home! It's All About Chemistry!

Today’s theme for STEM-ing At Home is focused on one of our favorites —chemistry.

Become a Chemistry-Spy for the Day- Make Invisible Ink

Who wants to become a Chemi-Spy for a day?  Channel your internal spy persona with this fun STEM activity.  The kids can create secret messages as part of a scavenger hunt.

Materials:

  • Baking soda

  • Paper

  • Water

  • Light bulb (heat source)

  • Paintbrush or swab
