National Geographic’s Little Kids website has found a fun and messy experiment to teach your little kid about the liquid and solid phases of matter. Before conducting the experiment read over all the directions with your child and have them form a hypothesis, what they think will happen. Encourage their curiosity by having them feel all the components of the experiment, water and cornstarch, before making their hypothesis. Once they have decided on their hypothesis conduct the experiment.

Here’s what you’ll need for this cool experiment:

  • Newspapers (This can get very messy!)
  • Mixing Bowl
  • 16 ounces of Cornstarch
  • Measuring Cups
  • Water
  • Blue Food Coloring (or whichever color your child prefers)

 

Experiment Procedures:

  1. Pour the 16 ounces of cornstarch into the mixing bowl.
  2. Use the measuring cups to add 1 ½ cups of water to the cornstarch.
  3. Add about 15 drops of food coloring to the mix.
  4. Here is the fun part! Use your hands to mix the experiment ingredients.

Now they you’ve made your blue goo ask your child some questions as they play with it. Was their hypothesis correct? Or was it incorrect? How does the blue goo feel? Does it feel more like the water or the cornstarch? Point out to your child that if you squeeze the blue goo in your hand it feels like a solid but if you open your hand it spreads out like a liquid. The blue goo can act as both a liquid and a solid!
