All you need is a base plate and a handful of basic bricks. Make it as easy or complicated as your imagination wants. It is so fun to build a LEGO marble run and it is a perfect example of a STEM activity using basic bricks. Combine design and engineering for a STEM idea that will provide hours of fun and laughs! We love simple LEGO building ideas!
Make A Kids Marble Run
You don’t need a giant collection of bricks to build a marble run or marble maze, but you do need a marble or two. Build it simple or build it extreme, but don’t lose your marbles over it!
This Lego marble run is so easy to build and super fun to play with for quite a few ages, at least 5 to 70 to be exact!
Of course you can also make a marble run or marble maze with cardboard tubes, pool noodles, or a paper plate! A magnet maze is a fun alternative to try!
What Is STEM For Kids?
STEM sounds complicated, but it isn’t! Once you get how science, technology, engineering, and math (STEM) mingle, you can see how it applies to so many of the science and STEM activities you already love.
The best STEM activities encourage your kids to use at least 3 of the 4 pillars of the STEM acronym (science, technology, engineering, and math) to tackle their projects head-on, challenge what they know, and build character. The lessons STEM can teach our kids are priceless!
Have you played around with science with your kiddos? If you haven’t, you are in for a real treat. And if you have, you already know how much fun STEM activities are…
Unlock your kids’ curiosity, and spark their inner inventor! The world of science and STEM is AMAZING with these hands-on science experiments and STEM activities!
You don’t have to be a rocket scientist to share STEM with your kids. We have everything you need: simple-to-follow activities, low-prep ideas, easy-to-digest science information, and inexpensive supplies.

Extension: Turn It Into A STEM Project
If you want to extend the activity as part of a STEM lesson for older kids, you can have them research design ideas and draw a preliminary design before they start building. Is their marble run design possible? Does it need some tweaking?
You can also set out additional mini-challenges for kids who have built marble runs already and need a greater challenge when it comes to designing a marble run.
Also, if you have several base plates handy, can the kids build a mega LEGO marble run?
Fun Marble Run Variations
Here are some additional marble run challenges to try or elements to add:
- Include a set amount of turns the marble must make before it reaches the finish line.
- Create a tunnel or other feature the marble must travel through.
- Build a ramp for the marble to go up and back down again.
- Add in a door for the marble to roll through.
- Create obstacles the marble must avoid.
DIY Marble Run
Supplies:
- Basic LEGO bricks
- Marbles
- LEGO Base Plate
Instructions:
Now grab your pieces and let’s get started! The key to success is to make sure the marble can fit everywhere you want it to fit!
The best way to start your LEGO marble run is to build a frame around the outside of the baseplate leaving two holes, one for the start and one for the finish. Use your marble to measure as you go!
Add a piece, remove a piece, you might find a corner too tight for the marble to roll through, so you will need to rethink the design and change it around!
It can become a really cool problem-solving activity. You could make just one path that will work to get to the finish, or you can make several!
