With a sweet crystal science project, you'll do two things at once: see how crystals form in nature, and make candy!

What You'll Need:

  • Saucepan
  • Water
  • Sugar
  • Glass jar
  • String
  • Pencil
  • Popsicle stick

Step 1: With the help of an adult, boil half a cup of water in a saucepan.

Step 2: Add a cup of sugar one spoonful at a time until all the sugar is dissolved. Keep adding sugar until the solution turns into a clear syrup.

Step 3: Let the syrup cool for about 10 minutes, then pour it into a glass jar.

Step 4: Get a piece of string about six inches long. Tie one end of the string around a pencil, then tie the other end to a Popsicle stick. Put the pencil on top of the jar so the Popsicle stick hangs in the syrup.

Step 5: Set your 'crystal maker' aside. Take a look at it every day to see what's happening. In about a week, the syrup should be crystallized and ready to eat!

Now that you've grown candy crystals, you can try your hand at a more advanced crystal growing technique with the next experiment.
