As my son has gotten older, LEGO activities have taken center stage in much of our play and learning time. Of course, all these awesome LEGO activities include science experiments and STEM challenges too! After all, LEGO is all about building, creating, exploring, and expanding the imagination.

Our LEGO STEM activities are easy to do at home or even at school because we try to use basic bricks or types of bricks you may already have. Our LEGO collection is still growing, so we don’t have everything yet 😉


LEGO Activities and Play Ideas STEAM challenges


LEGO is one of the best known toys around, but it’s so much more than a toy if you look closely. LEGO can be used to teach mathematics, science, engineering, and even technology or what’s known as STEM!

What else can LEGO do? LEGO works on developing fine motor skills. Have you seen how small some of those pieces are?

LEGO also inspires kids’ imagination and creativity. It teaches us how to problem solve, and how to use intricate details to make a design come alive.


If you take peek at some of our LEGO STEM activities below, they might seem like an unconventional way to use LEGO. We spend a great deal of time free building from a large box, but we also have some inventive ways to play with our bricks and figures too.

Think outside the brick and see how else you can use your LEGO pieces. Build a volcano for a science experiment, carve a pumpkin and make a LEGO scene, or design parachutes for Minifigures and test them out.

LEGO STEM activities can keep everyone busy in so many ways. When you want to take a break from LEGO building, why not try some of our awesome science experiments for something different!
