Easy Santa STEM Challenges

Modified: Nov 14, 2024 · Published: Dec 2, 2020 by Emma Vanstone · This post may contain affiliate links · Leave a Comment

My Santa STEM Challenges might be my favourite Christmas science activities so far. Help Santa find the North Star, save a pile of presents from crashing to the ground, make a tree and build a raft for the reindeer with these exciting Christmas STEM Activities.

Four of the challenges are now available as FREE STEM challenge cards, too! Print the cards, grab the materials and start experimenting!

Santa STEM Challenge cards

Santa STEM Challenge 1 

Poor Santa seems to be in a bit of a pickle. Can you help him out?

Santa STEM Challenge - find the North Star

Before the days of radio and satellite navigation systems, people used the stars to navigate. The North Star is a useful marker as it remains in one spot in the Northern Hemisphere. Can you find out how Santa can identify the North Star, maybe you could learn about constellations, too?

Challenge 2 – Lost Compass

Make Santa a compass STEM challenge

Did you know the Earth acts like a giant bar magnet, creating a magnetic field? Magnetised metals naturally align themselves with this magnetic field. You can utilise this effect to make your own compass.

Challenge 3 – Broken Toys

Make glue to fix the toys, Santa STEM challenge

Did you know you can make glue from milk? You’ll need an adult to help, but it works surprisingly well.

Challenge 4 

Catapult Santa STEM challenge

Lolly stick catapults are brilliant for firing objects through the air and are very easy to make using craft sticks and elastic bands. Once the catapult is made, experiment with different sizes and shapes of objects ( pom poms and ping pong balls are a good starting point ) to find out which travel the furthest.

If you think Santa might need more power than that, try a giant catapult outdoors!

Santa STEM Challenge 5

Build a shelf for the Elf Santa STEM challenge
  • How would you build a shelf?
  • What materials could you use?
  • How would you attach it to the wall?
  • Is the elf heavy?
  • How much weight can your shelf hold?

Challenge 6 

Build a tree Santa STEM Challenge
  • How tall can you make the tree?
  • Is it easier to build a tall tree if the base is wide?

Reindeer raft Santa STEM challenge
  • What materials can you use? Try cork, lolly sticks, sponges etc.
  • How can you make the raft waterproof? Experiment with kitchen foil, paper towels, paper bags and other materials.
  • Test to determine if your raft is strong enough to hold a small present without sinking.
