Building with LEGO® is pretty cool and great for LEGO STEM activities!  This time, my son wanted to try out a zip line like we had seen in a book. I knew there would be several interesting concepts he could explore through hands on play!  Check out our collection of over 40 unique LEGO activities for kids.  So many great ways to incorporate LEGO into a STEM environment!

Build A LEGO Zip Line For Simple Physics

Science is everywhere! You don’t need to purchase a fancy science kit to set up awesome science activities for you kids. We love to do STEM activities using simple items from around the house, with inexpensive materials and supplies you may already have on hand!

This LEGO zip line activity is truly the perfect way for kids to look at ordinary items in new ways and invent something different with them. Science doesn’t just come in a box, well today maybe a LEGO box!

Getting started with a LEGO zip line. My son’s idea was to build something for a LEGO® guy to sit in as he zipped down the line. This is a great opportunity to test out those master builder skills!

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.

Helpful STEM Resources To Get You Started

Here are a few resources to help you introduce STEM more effectively to your kiddos or students and feel confident when presenting materials. You’ll find helpful free printables throughout.

How To Make A LEGO Zipline

Also check out our LEGO zip line with a homemade pulley system.

Supplies:

  • Basic LEGO bricks
  • Parachute cord or string

Instructions:

I helped him start by putting a LEGO mini-figure on a base and suggested that he build up and around him! When he reached the top, I told him he needed to leave a space for our parachute cord to slide through. He wanted to use two curved pieces, but they are not necessary.

So now that you have your LEGO® man safely secured in his contraption, it’s time to set up your LEGO zip line.

How To Secure Your Zip Line

Our First Zip Line

We actually started by securing the parachute cord to the door handle and then securing the other end on the railing of our 2nd floor balcony.

My son was very excited….until it crashed and broke.  Here’s a good time to explore some scientific concepts like slopes, gravity, force, etc !

Make sure to ask questions!

  • What makes the man travel faster down the zip line? 
  • Is a steep slope better?
  • What happens to the LEGO® man when he gets to the end?

For our first zip line, the angle of the slope was too great, gravity pulled it down very fast, there was no breaking method or friction to slow him down, and the force that he hit the wall with broke him apart! Read more about our zip line fun below.

Our Second Zip Line

We cut the parachute cord shorter. Again I attached it to the door handle, but I showed him how we could be the other anchor for the zip line.

By keeping tension on the line and raining our arm up and down, we could control the slope of the zip line. He loved that he could use the lego zip line to make the LEGO® man travel back and forth.

If my son did not keep the cord tight however, the LEGO® man was stuck. Great hand-eye coordination activity too!

Build a quick and simple LEGO® zip line with just a couple of items! Next time maybe we will add a pulley system, but for now this playful, easy LEGO® zip line was perfect for afternoon play. The discoveries made will last a lifetime!

What You Can Learn Through Hands-on Play

  • Speed up the LEGO man by increasing the angle of the slope.
  • Slow down or stop the LEGO man by reducing the angle of the slope.
  • Return the LEGO man by decreasing the angle of the slope.
  • Gravity works to pull the LEGO man down the zip line but the angle of the slope can work against gravity.
  • Tension on the cord is needed to maintain travel along your zipline.
