Creating Salt Crystals

Creating Salt Crystals

There is something fascinating about taking common objects and creating something new with them. My son and I had a great time experimenting with rocks, salt, and water to see what would happen.

Ages:
4 - 9
Est. Time:
<30 mins

How we did it:

Materials List

  1. salt (1/4 cup)
  2. water (1/2 cup)
  3. rocks / stones (5)
  1. We started by heating up the water in a pot on the stove on high.

  2. Then we added the salt to the mixture.

  3. The next step was to stir the salt and water until there was only a little salt left in the pan. I stuck right by my son's side as he stirred as I do any time he is working on the stove. As he gets older, I will back off a little, but for now I stay right beside him.

  4. While I gave the salt mixture a final stir or two, my son placed the five stones into a shallow pan.

  5. I then poured the hot liquid over the stones. Eventually, crystals started to form--how exciting!
