Creative Christmas STEM Activities Your Children Should Try!

10 minute read

STEM needs to be where kids are.

Whether that's at home, during Christmas, or in the TV shows they're watching, STEM can never be an afterthought if you want to raise successful kids. 

That's why apart from school, kids rolling up their sleeves and doing hands-on learning at home is the best way for them to gain a deeper and more detailed understanding of STEM. That's the reason why STEM activities exist. The goal of these hands-on projects is to draw out children's inquiries and promote in-depth investigations

This Christmas, make the most out of the celebration by adding a holiday twist to their STEM activities. We listed outstanding holiday arts & crafts as part of your kid's ultimate STEM-themed Christmas celebration. Check out how to do the Creative Christmas STEM activities below!

1. Christmas Ornament Making Project

Christmas Ornament Making Project

Instead of buying ornaments online, why not create them with your kids? This would be a splendid avenue to extract some artistic juices and learn some milk-plastic chemistry! This Christmas STEM activity deals with making plastic using milk and vinegar (don't worry, it's environmentally safe!). 

While these two seem like the most unconvincing partners, you'll be amazed at the result! You can find the in-depth recipe for this easy DIY Christmas craft below.



  • 1 cup of milk

  • 4 tablespoons of vinegar

  • 1 mug/cup

  • Paper towels 

  • Paint and brushes

  • Cookie cutters, shape mold, markers (optional)



  1. With the pan, HEAT one cup of milk on a stovetop until it begins to steam (Alternatively, you may heat the milk using a microwave at 50% power for 3-5 minutes. It should have a similar temperature.).

  2. PLACE 4 tablespoons of vinegar in a mug or cup.

  3. POUR the steaming milk into the mug. This process should form whitish clumps called "curds".

  4. STIR the mixture with a spoon slowly for several seconds.

  5. Once the mix starts to cool down, SCOOP all the curds with a spoon and transfer them over some paper towels to dry. Eliminate the liquid that's left from the mug.

  6. FOLD the edges of the paper towel towards the ball of curds to absorb all excess liquids.

  7. Within an hour after extracting the curds, you may now MOLD, SHAPE, PAINT, and DESIGN your milk plastic. 

If you need to see how to do this STEM craft, here is an instructional video:

Here are some awesome designs of this DIY Christmas craft. STEAMpoweredfamily molded their milk-plastic ornament into a Santa and painted it accordingly. 

On the other hand, Science Buddies created a diverse collection of milk-plastic decor shapes.

2. Building Gingerbread Houses

Building Gingerbread Houses

The following Christmas STEM project deals with some engineering and fine motor skills in children. After all, the E in STEM stands for engineering. So why not put kids' creativity to the test with some gingerbread house challenge?

The goal of this Christmas craft for kids is to unleash their inner artists while infusing engineering concepts to create the perfect build. Plus, all of you can munch on the masterpiece afterward, so it's a win-win!



Note: Whatever materials you use for this DIY Christmas craft is your choice. Listed below are the ones my kids and I used when we did this holiday STEM project! Feel free to buy the same or choose your own building tools.

  • Structure and pillars (Gingerbread, graham crackers, pretzel sticks)

  • Glue (Frosting, melted chocolate, melted marshmallows)

  • Random candies for decoration



Kids call the shots when making the building. You may guide them but let your children take the lead. The point here is that they have a fantastic time with this Christmas STEM activity.

  1. PLAN the design of the building your kids wish to create. A printed illustration might help. We recommend a nativity design to add some Christmas-themed feel to the project.

  2. USE graham crackers or PREPARE your gingerbread dough for the materials used. The former is more straightforward and significantly easier to do than baking your dough. 

  3. ESTABLISH the base first and work your way upwards. 

  4. FILL your gingerbread house with candies to add some color and life.


3. Edible Stained Glass

Edible Stained Glass Activity

Nothing screams Christmas than spending the holidays in church. But with the blizzard starting to build up, maybe we can take the church feel at home? This December STEM activity brings the stained glass aesthetics of cathedrals into your own hands!

The edible stained glass project is a fun STEAM project that uses chemistry and geometry. You will need the right temperature to get the best consistency and good command of shapes for accurate designs. Check the recipe for this holiday Christmas craft below!



  • Hard candies like Jolly Ranchers (assorted colors)

  • Pretzel sticks 

  • Aluminum foil



  1. LAY a layer of aluminum foil over that table to serve as your workstation.

  2. MAP out the skeleton of your edible glass design using pretzel sticks.

  3. PLACE your Jolly Ranchers on a microwaveable bowl and heat at 50% power for 2 minutes at a time.

  4. TAKE the bowl out and MIX your melted candy to prevent them from sticking to the bowl.

  5. REPEAT steps 3 and 4 as needed until you get the molten glass consistency.

  6. SCOOP the candy with a spoon and spread over appropriate areas in your edible glass design.

  7. If your candy hardens, you may REHEAT them at 30 second-intervals to avoid burning.


4. Flying Reindeer Straw Art

Flying Reindeer Straw Art

The next Christmas STEM craft idea is pretty simple to make. You can get all the supplies you need for this craft in your nearest department store. In this activity, kids get to create their reindeer design and get that art flying, just like Santa's reindeer! Plus, you can produce an incredible STEM challenge out of this easy DIY art project.



  • Paper Straw (with red and white)

  • Printed or drawn picture of a reindeer (or any critter you like!) on a 2" x 3" paper

  • Plastic pipette

  • Glue (preferably glue gun)



  1. PRINT out or DESIGN your flying reindeer (or any critter). 

  2. CUT the long stem of the plastic pipette but leave around half an inch of the stem intact to the bulb draw (head).

  3. The opening of the pipette must be wide enough to fit your paper straw snuggly. Feel free to TRIM more from the pipette stem until your kid gets the perfect fit.

  4. GLUE the design you made to the bulb draw using a glue gun or stick glue.

  5. INSERT the paper straw inside the small opening of the pipette.

Here is an instructional video to help you out, but in this tutorial, they used a bat instead of a reindeer:


What happens next?

The trick here is for your kids to blow through the paper straw as strongly as they can. The pressure from their breath gets trapped in the bulb draw, causing the pipette to propel into the air. In the eyes of your preschoolers, it looks like the reindeer are flying. This is the secret behind this simple, easy DIY Christmas STEM craft!


5. Christmas Science Lava Lamp Bottle 

Christmas Science Lava Lamp Bottle

What good are DIY Christmas crafts for kids if they can't put them on display? This next art project is a fun way to teach children about density, and it looks so beautiful, you'd want it on display this holiday season! So bring the fascinating beauty of lava lamps to a simple STEM Christmas art project.



  • Plastic bottle (Ideally, VOSS water containers for added aesthetic feel)

  • Baby oil

  • Water 

  • Festive food coloring (green, red, yellow, blue)

  • Alka-Seltzer tablets



  1. FILL around ⅓ of the plastic bottle with baby oil.

  2. MIX your water with the food color of your choice.

  3. POUR the colored water gently into the plastic bottle containing baby oil until ⅔ of the bottle is filled. Let your kids note what happens when you pour the water over the oil.

  4. DROP a tablet of Alka-Seltzer into the colored water and oil mixture and see the lava lamp magic come to life.


So what happened here?

Oil is less dense than water. That's why water seeps down to the bottom of the bottle. When you add Alka-Seltzer to the mix, the interaction between water and the tablet creates air pressure that pushes water upwards. But the water again subsides down the bottle since it is denser than oil. This trifecta of effects creates the lava lamp-like aesthetics! 

What little bins for little hands did with their Christmas lava lamp looks pretty astonishing!
