LEGO Santa Sleigh STEM Building Challenge

The holidays are upon us, but that doesn’t mean learning has to stop. In fact, one of my favorite things to do is to apply STEM principles to holiday activities for kids. A holiday theme is less intimidating for kids new to STEM and it helps children see how STEM thinking can be applied anywhere! Of all the holiday STEM challenges we’ve done, I must say that this LEGO Santa Sleigh STEM Building Challenge is one of our favorites. The results from our experiment were surprising, but tickled us. You’ll soon see why below!

Challenge the kids to a LEGO Santa sleigh building game. Who can build the best sled for Santa? It's a great Christmas themed STEM activity.

Setting Up Your LEGO Santa Sleigh STEM Challenge

This STEM challenge starts with a simple idea. Why does Santa keep using a sleigh? Should he be using something more efficient and modern?

We used LEGO blocks as the building material for our sleigh-building test.

What you’ll need:

  • LEGO bricks (we used red, green, and white bricks for our sleighs and found three packages to carry and three LEGO guys to represent Santa.
  • Stopwatch
  • Paper and pencil to record your results

Building Your Sleigh Models

We decided to make three designs. We did a classic Santa sleigh, a sleigh on wheels (AKA, a car), and a cart pulled by a motorcycle. Each sleigh model had to hold both the Santa model and the package. If the kids in your crew want to make even more designs, go for it! The important thing is that the kids create and build their own designs.

Testing the LEGO Santa Sleighs

We conducted a series of experiments on each LEGO Santa Sleigh. We tested each vehicle three times for each test and averaged the results to get our final result.

  • Speed test
  • Crash test
  • Distance test
  • Safety test

Speed/Safety Test

We tested each vehicle three times. We wrote down how many pushes it took to get our vehicles down the hall, how long it took to make it down the hall, and whether the sleigh fell apart. The traditional sleigh design blew away the competition in this test.

Crash Test

We pushed our vehicles into a wall and noted which vehicle remained in tact. In our tests, the car style sleigh and the traditional sleigh were equally safe.

Distance Test

For this test, we pushed each vehicle using the same force. We then measured how far each vehicle traveled on that push. We were surprised to see that the traditional sleigh traveled farthest.

What is the Best Sleigh Design?

According to our tests, the traditional sleigh design one. It was consistently the safest, fastest, and least likely to break. The kids concluded that Santa shouldn’t go out and change his sleigh design just yet.

STEM Elements

This activity includes everything you need for a comprehensive STEM project.

Science: The scientific method is applied to answer the question.

Technology: A stopwatch is used for the tests and LEGOs only exist thanks to technology.

Engineering: The children got to build and design their own sleighs.

Math: After running the tests, math was used to determine the winner.
