Lego Marble Maze

Last week we took our lego-obsessed superheroes to Legoland in Carlsbad, CA.  The boys had a BLAST while we were there and had fun building while my husband or I waited in line for rides.  That got me thinking… Lego and science?  Could there be a more perfect union?

We started our Lego explorations with a simple Marble Maze.  I had to help them get started but then they were on their own!

Here’s what you need to get started:

  • Lego or Duplo building plates
  • Assorted Lego or Duplo pieces

We used the smaller base plates for our first run but a Duplo base plate with a bouncy ball would be perfect for the younger superheroes in your life.

I showed the superheroes what a marble maze looks like on my computer and then gave them some tips to get started.  That’s it!  Easy!

Below is our first run:

My younger superhero made the one below, complete with a “blocking bridge” and a tower.

  • Build a border around the base plate to keep the marble in.
  • Make sure there is a clear entrance and exit.
  • Determine how wide the alleys need to be to accommodate the marble.
  • Determine how high the bridges/arches need to be to accommodate the marble.


Try using different size base plates, different size marbles/balls, tunnels, dead ends, obstacles, ramps, etc… the options are endless!  Have an A-MAZE-ing time building!

The Science hidden in this Activity:

Building is a wonderful way to introduce your superheroes to engineering, problem solving, creativity, etc… My boys are obsessed with Lego and sometimes they build while following the instructions (excellent for developing focus and the skill of following multi-step directions) and other times they build freely (excellent for creativity and problem solving).  Either way, it’s great for their brain!
