Welcome to a new series called educational challenges your family can do at home this summer before school starts back in the next few weeks. If you are looking for some fun engineering challenges for your children, I’ve got something to share with you. Simply using toothpicks and gumballs, youth will build a small bridge. It’s a quick lesson for youth to learn about the characteristics of different bridges and understand how to best create their bridge during the challenge. Once they compose their build, they can test the bridge with each other.
In order to complete this challenge (based on 10 kids), you only need four things – two packs of 100 toothpicks, four packs of gumballs, and random materials to test the strength of the bridge. I like to use washers.
- Discuss common problems needed to be addressed when building a bridge.
- Show pictures of real bridges and discuss the design features they have in common.
- Encourage youth to draw a design of a bridge and design a prototype using the materials. This is the fun part! You can set a limit to the number of materials or give them no limits at all. It’s really up to you!
- Once they complete their bridges, they can test their strengths using your measurement tool of choice.
