Fall Science Grow Pumpkin Shaped Crystals

We’re doing fall science today at Green Kid Crafts! Grow your own crystals at home with this easy STEM activity for kids. If you haven’t grown crystals at home it’s really easy and kids see results in just a couple days. The process of growing crystals is visual and kids can document their observations in class or at home as an extended learning activity.

  • Orange pipe cleaners
  • Pumpkin shaped cookie cutter
  • Twine, string or ribbon
  • Popsicle stick
  • Borax
  • Water
  • Jars

Directions For Making Crystals

  1. Bend the pipe cleaner around the cookie cutter so it forms the shape of a pumpkin and then twist the ends together.
  2. Tie string to the pumpkin
  3. Boil 2 cups of water and add 1/2 cup of Borax in the boiling water. Stir until the Borax dissolves. If it’s not fully dissolved the project won’t work as well.
  4. Hang the pumpkin shape in a jar by securing the loose end of the string to a popsicle stick.
  5. Pour the water mixture into the jar making sure the pumpkin is fully submerged.
  6. Watch the crystals grow over the next day or two.
