LEGO Balance Scale STEM Project 

---

When my son was 4 years old, it was a BIG Lego phase for him. He was so into looking at the Lego building app and followed the instruction to building what he wanted. We made a LEGO balance scale and weighed candies. It was fun, and it turned out an excellent STEM project to introduce him to how to use scale and what weight is. I want to recommend the source we used back then, but I have NO memories of which one we used… So I found some websites and some Youtube videos. Hope it helps!

Build a LEGO Balance Scale (mombrite.com)

I found this website very educational and explains with STEM learning points of view. I love they have science extensions, and you can get more detailed ideas to teach what the weight is. Great learning source!

Videos

This video’s instruction is in French. The animated step by step video helps tons when we make LEGO with preschoolers!

Happy learning!
