Today's activity was ice chalk mixing. To create ice chalk, I mixed equal parts corn starch and water in a muffin pan, added food coloring, and froze with a craft stick inside.
I imagined they'd be able to paint with them, but it didn't quite work that way. We dunked them in water and they started to melt a bit, but still they were useless for drawing. However, we turned it into a great color mixing activity! This was a fun way to demonstrate how yellow and blue make green, red and blue make purple, red and yellow make orange, and so on. They really enjoyed mixing the colors and seeing all the combinations they could make.
I'll need to work on the recipe to make ice chalk that actually draws, but this was a fun and educational activity for this hot summer day!
