Christmas STEM Projects

Holidays are a great time to pull in some themed STEM projects. Even kids who aren’t usually into science can get excited about making a reindeer fly or making a Christmas tree out of 3D shapes. Check out these fun Christmas STEM activities to try in your classroom or at home.

Speaking of making reindeer fly, there are lots of different takes on this engineering challenge. In the instructions from The Educator’s Spin on it, kids make a reindeer from recycled materials, then use a string to make it “fly.” You can also do this with a balloon, like in this version from Team Cartwright.

And that Christmas tree project? That one is from Steamsational, and it calls for making a bunch of 3D triangles you then assemble into a tree. The post includes all the tips you’ll need and a printable template for making the triangles.

Another cute idea from Steamsational is making Santa’s sleigh out of an egg carton. Give kids design challenges such as that Santa must stay in the sleigh, it should be able to move and pull weight. It’s so fun to see what kids come up with.

Science Sparks has a printable book full of Christmas-themed experiments with templates kids can cut out and use to make spinning sleighs, shadow puppets, a paper tube to test how much weight it can hold and more. These activities are really low prep beyond the printing, so they’re great when you need to fill a little time at home or at school.

If you have Legos and jingle bells you can make a simple engineering challenge by having kids build mazes that the bells can roll through. Get the details from Innovation Kids Lab. (And check out this fun book of Lego Christmas ornaments!)

Of course you can also put a Christmas spin on classic STEM activities, like making a baking soda volcano in a plastic or glass ball ornament (Little Bins for Little Hands), red and green magic milk (Fun Learning for Kids), Borax crystal ornaments (Go Science Kids) and more!

Build a Peep Launcher: Springtime STEM

When my daughter was younger she had a ton of LEGO bricks, and I’m honestly a little sad we got rid of most of them because there are so many fun things to do with LEGOs outside of the kits you bought them in.

I love seeing all the ideas people have for LEGO building challenges, and I have shared some ideas for LEGO games before, but I saw one on Pinterest the other day that I felt was worth a mention.

This one is for those ’80s and ’90s kids who spent sick days home from school watching “The Price is Right”: LEGO Plinko!

For those who don’t know about Plinko, the original was a giant peg board set up at an angle and the contestant would drop a flat disc at the top of the board. As it moved down the board it would hit the pegs and change the way it moved, and there would be different prizes in the slots at the bottom where the piece would land.

This version from Play Party Game works on the same principle, using LEGO bricks to make the game board and marbles in place of the Plinko disc since your game board isn’t flat.

You can really use whatever bricks you have for this build, and while it shows all the pegs the same size and evenly spaced, you can play with different configurations and see what happens. It’s engineering and a game!

And while you’re playing with your LEGOs, make sure to check out this post from Kids Craft Room that includes minute to win it style games you can do with LEGO. From speed sorting to tower building as fast as you can, these ideas are sure to get you thinking about different ways to play with LEGO.

And if you need even more ideas, check out my post with LEGO building challenges you can print out for kids (and adults!) to try.
