This experiment requires adult help. Never use a cooking range without adult permission and supervision.

In this experiment, we're going to learn about solution concentration and what happens when we super saturate a solution. We used two jars to make four rock candies in our test, but why not experiment and see what you can make?

Procedure

  1. Step 1

    Heat the water to a boil in the saucepan. Remember, adult supervision is required for this demonstration.

  2. Step 2

    Stir in the sugar at 100g increments until it is completely dissolved in the water. If the sugar is not completely dissolved, crystals will attach to the undissolved sugar, instead of the stick.

  3. Step 3

    Remove the saucepan from the stove and allow it to cool for 20 minutes. As it cools, the water won't be able to hold as much sugar as when it was boiling and will become what is called super saturated.

  4. Step 4

    Pour the solution into your jars so that they are almost full.

  5. Step 5

    If you have food coloring, add it now. It's fun to use a different color in each jar.

  6. Step 6

    Wet one of your skewers with water and roll it in a small amount of extra sugar.

  7. Step 7

    Place the skewer upright into one of your jars and put a clothespin around it, resting on the opening of the jar, so that the stick remains upright.

  8. Step 8

    Repeat step 7 with the other skewers.

  9. Step 9

    Place the jars someplace safe and wait about one week or until there are a large amount of crystals on the skewers.

  10. Step 10

    Enjoy your homemade rock candy––made with science!
