24 Days of Christmas STEM Activities – Countdown to Christmas with our list of holiday STEM projects for hands on learning.
Christmas is coming and the kids are getting EXCITED! To keep them focused and motivated young scientists during this crazy time of year, I’ve put together 24 days of Christmas STEM Activities. This idea was a HUGE hit in October as we counted down to Halloween, so we are doing it again with a STEM Christmas. I’ve gathered up lots of cool science, tech, math and engineering activities to keep little ones busy. I even pulled out a couple of chemistry projects that my son is super excited about. I hope you enjoy our 24 Days of Christmas STEM Activities and it inspires your young scientists this holiday season!
NOTE: This list has been expanded and updated. Now with more than 24 STEM holiday challenges!

Instead of organizing by date, I decided to organize by type of activity. That way you can pick and chose what works best for you. Enjoy!
Christmas Science Activities
Crystal Wreaths – Create gorgeous ornaments that twinkle and sparkle on the tree using simple bits of garland and an easy science experiment.
Dissolving Candy Canes – A simple, fun experiment. Which liquid will dissolve the candy cane the fastest? Practice your scientific investigation skills with this activity.
Bending Candy Canes – After dissolving your candy canes why not challenge yourself to see if you can bend your candy canes into new shapes?
Rudolf Races – A physics challenge that kids of all ages love! Have a blast building and setting off your Rudolf to see who wins the race to save Christmas!
Snowy Christmas Tree Science – Such a fun idea! Kids love playing with oobleck and this activity gives them the challenge of building (engineering) a village before pouring oobleck over the structures and materials to see how it reacts. I know this will keep my kids busy for a long time!
Candy Cane Play Dough Soap & Bubble Bath – Make your own play dough soap and bubble bath using a very simple process even young kids can do. Scented with peppermint and shaped like candy canes these make a wonderful activity for the season.
Christmas Optical Illusions – We are really enjoying exploring our senses right now, and this Christmas activity has some illusions that are going to play games with your eyes! Can you believe what you are seeing?
Christmas Light Color Mixing Science – Color mixing theory is a wonderful connection between STEM and STEAM. We love bringing a little Arts into our STEAM work at STEAM Powered Family and this activity is a simple and fun way to explore colors.
Jumping Tinsel Static Experiment – What child doesn’t love playing with static electricity? At a recent science fair my kids spent over 30 minutes just playing with static. It is so much fun and really easy to do at home. Tinsel makes a fantastic tool for demonstrating the powers of static.
Simple Snow Science – The best part of Christmas is when it’s a white Christmas with lots of snow. This simple science activity explores the properties of the white fluffy stuff.
Christmas Chemistry Activities
Science Christmas Ornament Project – Milk plastic chemistry is the first step in this process to make extremely durable, beautiful ornaments. Start by making your very own plastic using items you have in your kitchen right now!
Christmas Tree Chemistry – This activity was so much fun and love making their Christmas tree creations erupt! I love that this activity brings in a little art to our STEM work.
Slime Balls Christmas Gifts For Kids – Slime is a wonderful sensory activity and an exploration in polymers. With this activity kids make beautiful ornaments filled with slime that they can gift to their friends. Perfect!
Christmas Slime For Hands-On Play and Fun with polymers – This slime recipe is perfect for the holidays! Kids will be kept busy for ages as they explore all the goodies in this slime. A great sensory and play experience.
Grow the Grinch’s Heart – this is a good old fashion vinegar and baking soda reaction with a fun twist and tie in to the story of the Grinch.
Want to try something that will really get kids excited about chemistry? Try some Candy Science and learn about the chemistry behind candy making while making irresistibly delicious candies like caramels, fudge, lollipops and more! The sweet treats are perfect for the holiday season and success in this science lab is soooo sweet!
Christmas Math Activities
Grow A Christmas Tree Math Game – This fun math game will be perfect for a snowy afternoon while we sit around drinking hot chocolate, having some fun and learning too!
Snowflake Symmetry – Understanding symmetry is an important skill in math and the holidays are a great time to practice these skills. In this activity symmetry is studied with snowflakes.
Christmas Tree Symmetry Activity – Another great symmetry activity, this one using Christmas trees and is a more simple design, great for younger children.
Math Garland Christmas Countdown – I love this idea! It’s like a math advent calendar. Perfect for the season!
Christmas Tech & Circuits
Christmas Keyboard Ornament – Got a kid that loves to tinker and a few old keyboards around? Why not use those old keyboards in this tinkering activity that has kids tearing apart old keyboards to explore the inner workings, then using the keys to create a one of a kind ornament.
LED Light Up Ornament – We love our LEDs and circuits but Circuit-Tree can be a bit challenging for some children. This activity is a more simple circuit design.
Christmas Bell Binary Key Chain – Love this fun activity that kids can do to create key chains with secret messages coded into them with binary code. What a fantastic gift idea!
Christmas Engineering Challenges
Christmas Egg Drop – Egg drop challenges are new to us. I have quite a severe egg allergy, but I really love the engineering challenge in this activity. Maybe we will get a break in the weather and can do it outside. I would love to see what my kids would build!
Gum Drop Christmas Tree Build – Building a tree with candy is a great way to add a little something to your gingerbread house projects! Challenge kids to build a tree that is stable and beautiful.
Build Tinkering Trees – Using nuts and bolts to build a tree? I know my boys are going to go crazy for this activity! Tinkering with those kinds of items is always fun and this will be a great way to spend an afternoon.
Ice Lantern Engineering – These lanterns are gorgeous and so much fun to make. The perfect outdoor decor to welcome your guests.
Icy Christmas Tree Engineering – We had so much fun building our Ice Dino structure, this holiday version is going to be a big hit! I love the idea of freezing things in the water for a beautiful finished product.
Christmas Tree Cup Tower Build – I know we are going to have days where the kids are housebound due to the weather and hyper! This challenge is going to be fantastic for those days. I can see many hours being spent building and knocking down their structures.
The Final Christmas STEM Activity – Day 24
And we will wrap up our 24 days by spending the final day with the best Christmas STEM activity of them all! We will be tracking Santa’s progress around the world! My boys love following him on Norad. Even though my oldest is no longer a believer, he still enjoys seeing the names of all the different places in the world and calculating how much longer until Santa arrives at our house!
There are some great additional activities you can add to your Norad Tracking here!
