A Quick Color Lesson

process2

I was putting the dishes up and had a mad, crazy idea.  3 minutes later, voila!  Science experiment!

It didn’t quite go the way I thought it would, but hey, that’s science.  We’ll try again later.

You’ll need:

  • Baking soda
  • Food coloring or paint
  • Vinegar
  • Small container for the vinegar
  • Small containers for the baking soda – in this case, mini muffin pans.
  • Eye dropper
  • Toothpicks

materials

I put approximately 1/2 of a teaspoon of baking soda in each muffin hole.  Then I put a small dot of food coloring gel in each hole.  Because the gel is concentrated, it’s difficult to see what color it is (except for yellow.)

Our colors were red, pink, orange, blue, teal, yellow, green, and purple.

I plunked the kids down at the table and handed them an eyedropper and a cup of vinegar.  Drip drip fizzle!   As the kids added vinegar, the baking soda fizzled and the color began to expand in the cup.

We discussed chemical reactions, solutions, and dispersion.  We investigated what happened when we stirred the remaining baking soda with a toothpick.  Not too bad for spur-of-the-moment science.

The Engineer began to do some color combinations, but that ended quickly because the kids complained about the vinegar smell.  Done!

finished

The hardest part was cleaning up without splashing it on anything that would stain.
