Need more LEGO® STEM ideas? She was having too much fun lining up all her LEGO® girls on the bridge to care about the bridge’s functioning! Oh well, she’s only 4.īesides being a fun STEM challenge, our bridges provided all kinds of entertainment! The bridge on the left held an amazing amount of weight! Janie’s bridge (on the right) wouldn’t hold much weight, but she didn’t want to reinforce it at all so we didn’t. You can take the challenge a step further by testing how much weight the bridges will hold. The supports of a bridge that go into the ground are called the piers or piles. If you reinforce your bridge with a layer of overlapping plates, it will be much stronger. Just one layer of LEGO® bricks won’t be very strong or hold much weight. The bridge’s beam, or the horizontal part of the bridge, needs to be strong and able to hold a lot of weight. You can also discuss what it means to reinforce something. They must do this using only drinking straws. Kids can learn about the concept of a bridge’s span. In this activity children are challenged to build a bridge 50cm wide to support the weight of a food tin. There’s all kinds of great vocabulary to discuss while building bridges. For the older kids, I probably would have made the river a little wider to make it more challenging. I was shooting for this activity to be an appropriate level for Janie (4) and Jonathan (6). You may want to draw your river wider (or narrower) based on your kids. It really doesn’t matter what exact bricks they are as long as you have a good assortment of bricks and plates (flat bricks). You’ll want to have an assortment of bricks for this challenge. We easily fit all of our bridges onto one river, and the kids still had room to work. If you’re doing this activity with a group, I would suggest one poster board for every 3-4 students. I grabbed two sheets of poster board to use with 4 of my kids. I decided to use poster board as an easy way to create a river.

In order to build a bridge, kids need to have a visual goal of the distance their bridge should span. I love activities like this because they are beneficial and engaging for a wide range of ages. Here’s a fun STEM building challenge for kids! Set up this bridge building activity and challenge kids to construct a sturdy LEGO® bridge that spans the width of the river.
