Christmas Candy Chemistry Science Experiments

Everywhere you go during the holidays, you see candy! Candy canes, chocolates, peppermints, dreams of sugar plum fairies :)  How about using all that candy for a little bit of learning?  Specifically some Christmas Candy Chemistry Science Experiments.  It’s another project where STEM gets delicious! 

Have some science fun with all that yummy Christmas candy. Christmas Candy Chemistry is STEM learning made fun and festive.

Christmas Candy Chemistry Experiments

There are a bunch of fun ways you can learn with candy this December.  We’ll start by exploring states of matter, one of the most fundamental parts of science and Christmas candy chemistry. We’re exploring melting points by making Peppermint Ornaments (or maybe I should just call them Ornamints!) by melting candy in the oven. It’s cool to watch how candy can go from solid to liquid to solid again with just some heat.

You’ll need the following supplies:

  • Oven
  • Baking sheet
  • Parchment paper
  • Metal cookie cutters
  • Non-stick spray
  • Star mint candy

Here are the easy steps (my preschooler did almost every step, except the oven, by herself!):

  1. Preheat oven to 350 ºF.
  2. Cover cookie sheet with parchment paper. Pick your cookie cutters and spray with non-stick spray and place on cookie sheet.
  3. Fill cookie cutters with candies (they don’t have to be totally full).


  1. Bake for 10-15 minutes but watch carefully because timing depends upon the cutters you are using.
  2. Let cool for a couple of minutes and punch hole for hanging with a bamboo skewer.  Once cooled completely, remove from cutters, add ribbon or twine and hang!

Chocolate States of Matter

You can also teach the kiddos about melting points while making a batch of delicious chocolate holiday bark. I love this super-loaded Christmas Bark (from Averie Cooks) for an over-the-top candy that is super-fun for kids.


Dissolving Candy Canes || Lemon Lime Adventures

Explore solubility with this festive dissolving candy cane experiment.


Candy Cane Oobleck || The Chaos and the Clutter

Feel science with a non-Newtonian fluid (It’s a solid! It’s a liquid!) when you make this minty fresh goop.


Chocolate Truffle Experiments || Relish

This science experiment may be more for the grown-ups…  Explore how different ingredients change your decadent holiday chocolate truffles.


Bend Candy Canes || The Artful Parent

I love these creative candy cane sculptures where science helps you change the candy cane’s form.


Mint Fireworks:

Next time you’re in the dollar store, grab an extra bag of star mints for a colorful experiment or use the leftovers from your Ornamints. You’ll also need a shallow plate and some water.

The Science of Candy Fireworks

The melting stripes of a star mint make a gorgeous pattern. Candy such as star mints, Skittles & M&M’s contains artificial colors called dyes that are easily dissolvable in water. As the dyes move into the water, they diffuse across the plate. The dye molecules want to travel to areas of lower concentration of dye from areas where there is a lot of dye. Eventually, the colors reach equilibrium, where all the areas have equal concentrations of dye.

Mint Fireworks Experiment Instructions:

1. Arrange the candies in a circle around the outside of the plate.
2. Pour a small amount of water into the center of the plate. Use enough that all of the candies get wet on the bottom.
3. Watch the color patterns form!
4. Repeat with another pattern of candy. How did the colors change?


Christmas Science that Keeps on Giving Long After Christmas

Whip up a batch of amazing Peppermint Marshmallows to learn about candy science. You’ll want to add these to your holiday making every year they’re so delicious!
