Today's lesson: Making a Lego Marble Maze


Today's lesson: Making a Lego Marble Maze

Submitted by Audra Cottrell, program specialist, Girl Scouts of Central Illinois

Age range: Intermediate elementary through middle school

Use STEM (science, technology, engineering and math) skills to build a marble maze with an additional option to create a code. 

To create a marble maze, you can use an assortment of colorful legal bricks on a green base plate to build a path that the marble can roll through. If you don’t have Lego bricks at home, you can also use dominoes, straws or craft sticks to create a maze. Get creative and challenge yourself!

If you want to take it a step further, write a “code” to complete the maze. Visit to see a post that explains various levels of coding that can be applied depending on your child's age and skill level. The link also includes a free printable worksheet. 

If you are interested in more coding practice, you can check out a free smartphone app called Grasshopper. It features quick lessons that can teach users how to write Javascript, applying progressively more challenging levels. It was created by a team of coders from Google's workshop for experimental products, Area 120.
