STEM Challenge – Build a Bridge

I know building a bridge doesn’t seem like the most exciting STEM challenge, but I added a little twist to this one to make it more interesting.

STEM Challenge - Build a Bridge

What you’ll need:

LEGO, DUPLO or other building blocks

String

Craft sticks or anything else you want to use to make your bridge

Cars/weights to test it

Instructions

We built two supporting ends for our bridge and attached string as shown in the photo above to support it.

Once you’ve built the basic structure the rest is up to you. What could you use to make a strong bridge and how will you test it?
