Outdoors STEM: Build a Bridge

I was apprehensive about this project as it began, but the kids soon convinced me it was worth all of our time and the effort they were giving it.


If I had thought about it at all, I would have realized that it combined some of the subjects I am most passionate about: outdoor play, child-led education, science, problem solving, engineering, and math!  But, I'm afraid the first thing that I thought of when my kids started this project on their own was that there had to be an awful lot of germs in that murky water!

Building a bridge can be done in *so* many ways.  We drove a short distance to a beach near this ditch.  As we played in the sand, the kids were soon distracted by this ditch and they challenged themselves to build a bridge across it. They wanted to get across it, and they were going to find a way!  If you don't have access to a ditch like this, you can create your own "river" to build a bridge across.  It can be an actual tunnel-like hole with water in it or just a line in the dirt!  We also have a rock "river" in our yard with a real bridge going over it that our kids play on.  But, that's not the topic for today!

Today, I'm talking about letting your kids (or even challenging them) to build a real bridge outside.  It uses problem solving, scientific reasoning, and qualitative math to engineer a creation that they can actually use!  STEM activities are beautiful to watch unfold because you can practically see children's minds working as they solve problems:

The bridge project began when my son started taking piling rocks onto the edge of the ditch.  It only took a few minutes before he realized that he could build a bridge all the way across the water using rocks.


They piled up pretty fast.  This is wonderful "heavy work" for kids who have lots of energy or who need a sensory processing release.

He quickly recruited help from his sisters, and they had a very big pile of rocks at the edge of the ditch.


I love how they had to work together to move the"heavy" rocks that had a flatter top.  Projects that require teamwork help children learn ways to collaborate and cooperate.


Finally, the bridge was done!

It had to be crossed immediately!


We even came back a week later and it was still there!



Try building a bridge outdoors and watch all the STEM skills interact as your children use scientific reasoning to problem solve and find a way to cross their own bridges! On a bad-weather day, you can even try an indoor version where you cross blanket or pillow rivers!

Have your kiddos ever built a bridge?  I'd love to hear about it and see picures!


We are participating in the 28 Days of Hands-On STEM activities for Kids!  Check out the homepage to see a list of all the great STEM activities you can look forward to this month! 






Happy Educating, Carla

Those are some big rocks! Good on you for letting them, there is so much to learn and experience from things like this. x
