Challenge #5 - Build A Bridge with Let's Build

Happy Friday!

This is our last post in a five part series of engineering projects to do at home. Do you have feedback? Ideas? Send to Liz at info@letsbuildengineering.org.

Today's challenge asks children to build a bridge strong enough to hold weight. As always, details are in the video below, materials and extensions are listed below that. Send photos of your children's work to info@letsbuildengineering.org and I'll post on letsbuildengineering.org and social media.

**Make sure to watch the introductory post - especially if you're new to the engineering design process.**

* Straws or popsicle sticks (optional)

* Tape and scissors
