Homeschool Science: Erupting Moon Rocks

moon rocks

Teaching your child about space? This experiment is an awesome way to discuss both moons and chemistry. Plus, it’s just about as fun to set up as it is to actually complete the experiment! Just remember to be prepared for a bit of a mess. Here’s how it works:

What you need:

  • Baking soda
  • Water
  • Black/silver glitter
  • Black liquid watercolor paint or food coloring
  • Squeeze bottles
  • Vinegar

What to do:

  • You’ll want to start out by making your moon rocks. Mix two cups of baking soda with about ¼ cup of water. Make sure you add the water slowly. You only want to make the baking soda stick together and you don’t want it to dissolve in the water.
  • Add a little bit of food coloring or paint, plus the glitter, to the baking soda and mix. You might want to have your kids do this with their hands.
  • Have your child use the mixture to form small balls. They should hold their shape, and these will be your moon rocks!
  • Leave the rocks out to dry until they are completely firm.
  • When the rocks are ready, fill your squeeze bottles with vinegar. Place the moon rocks in a container. Spread them out a bit so that you can have some control over the eruptions.
  • Now, use the squeeze bottles to squirt vinegar onto each moon rock. The vinegar will combine with the baking soda in the rocks to create sparkly explosions!
