These Santa STEM Challenges might be my favourite Christmas science activities so far. Help Santa find the North Star, save the presents, make a tree and build a raft for the reindeer with these exciting STEM Challenges for Christmas.
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 1
Poor Santa seems to be in a bit of a pickle, can you help him out?
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
Did you know that 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
Did you know you can make glue from milk? You’ll need an adult to help, but it works surprisingly well.
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, you could try a giant catapult outdoors!
Santa STEM Challenge 5
- 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?
- How tall can you make the tree?
- Is it easier to build a tall tree if the base is wide?
Santa STEM Challenge 7
- What materials could 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 find out if your raft is strong enough to hold a small present without sinking.
Can you think of any more STEM challenges for Santa?
