LEGO Zip Line Challenge

Our first ever super simple homemade LEGO zip line was immediately a hit! Why not add to it! SO we came up with another great idea using an actually pulley mechanism. This cool LEGO Zip Line Challenge is a great STEM activity for kids of all ages to have fun with and learn something from. We love easy LEGO activities!

LEGO ZIP LINE ACTIVITY FOR KIDS

Just a few simple materials are all you need to get started. STEM activities can be simple to do and set up at home! You can really make this LEGO zip line activity as easy or as complicated as you like depending on what you want to build and where you want to test it.

In my experience, kids love building things that go! This is the PERFECT challenge for crafting and creating something that goes with problem solving opportunities along the way. Also check out our self propelled car projects for kids.

Building this LEGO zip line is an awesome project for the kids that’s screen free. A great boredom buster for an inside day or a neat physics lesson for the classroom! Around here we look for cool hands-on ways to play and learn at the same time.

HOW TO MAKE A LEGO ZIP LINE

Check out the photos below to see how we crafted this cool LEGO zip line. We built a floor, a roof, two side walls, and an attachment piece to add the pulley. However, this is a STEM challenge, so try designing your own too!

We attached the rope to 2 fixed points in the house. You could also try it outside but keep track of the pieces if you have a crash landing! Test out different angles with the rope to explore force and motion.

Do different angles increase or decrease speed? Can you increase or decrease speed halfway through? Test out different designs to see which ones hold up better too! You can read more about the science of the zip line in our first post.
