Homeschool Science: Melting Ice

Melting Ice

Even if your area hasn’t experienced any snow this winter, you can still take advantage of this season and the teaching opportunities it has to offer. Has your child seen or heard about putting salt on ice to melt it? This experiment will help demonstrate how that method works and test what other substances can be used to melt ice. Here’s how it works:

What you’ll need:

  • Small paper cups
  • Cold water (for the ice)
  • Test substances
  • Hot water
  • Salt
  • Sugar
  • Baking soda
  • Vinegar

What to do:

  • To get prepared for this experiment, fill five paper cups with water and freeze them.
  • When the water is frozen, pop the ice out of the cups and set them on a tray or dish to catch the melting water. You can put them each in a separate dish if you’d like to keep them separate to easily see the differences.
  • Have your child put one of the test substances on one of the ice blocks. For example, sugar on one, salt on the next, and so on.
  • Your child should watch and observe, noticing which ice blocks melt faster and which hardly melt at all.
  • Write down observations, or draw pictures to demonstrate what you see.  Discuss the differences and then you’re done!
