10 Easy Bridge Building STEM Challenges for Kids


We see bridges and drive, and walk, over them all the time. However, we typically don’t spend a lot of time thinking about how they are built or how they can hold so much weight. However, there is a lot of planning, engineering and science that goes into bridge building. Encourage kids to look at the bridges around them in a whole new way, by building their own with these 10 Easy Bridge Building STEM Challenges for Kids.

My favorite part of doing STEM challenges with my kids, and students, is watching as they build and create. I have done countless STEM challenges in the classroom over the years, and without exception, the children have always come up with ideas and solutions that I would never have thought of. Their creativity always amazes me.

Children create without preconceived ideas of what a bridge or other structure should look like. With STEM challenges, they problem solve as they experiment and learn that if something doesn’t work, it’s not a failure, but rather a learning opportunity.

As STEM challenges are becoming more and more common and encouraged in schools, it makes me very happy and excited to for our future when I see what children create.

I’m sure many of you have had a bridge building project come home from school or perhaps you remember building a bridge when you were in school. It’s a common STEM challenge because it is meaningful and there is so much learning that comes from it.

If you are looking for a hands-on STEM challenge for home, or preparing a building unit at school, or specifically a build a bridge STEM challenge, these 10 STEM bridge building challenges are a great place to find ideas!

Bridge Building STEM Challenges

STEM challenges are activities that incorporate Science Technology Engineering and Math. Ideally the activities include all of these subjects, however, any activity that focuses on at least one of these skills is a STEM activity. Recently Art has been added to some of these activities, making them STEAM activities.

Kids of all ages benefit from STEM challenges. Young children tend to play more and experiment with their toys as they build and play. Older children often start to lose this as they get older. STEM challenges are a great way to keep this engineering and hands-on experimenting alive.

For all STEM challenges remind children that simply trying and not giving up is a huge part of the activity. Even scientists and engineers experiment and are not always successful as they plan their projects. What makes them successful is that they don’t give up. They learn from what went wrong and take what they learned and implement it into their next plan.

Preparing a Bridge Building STEM Challenge

To start a STEM challenge, let children know specifically what their challenge is. For many of the STEM challenges below, it is as simple as “Build a bridge that can hold some weight” or “Build a bridge to span over a certain area”. Keep it simple, and let kids come up with their own solutions.

Many STEM challenges use simple materials to build with. This is great for hands-on projects since children are already familiar working and playing with the materials.

When doing the challenge, allow kids to come up with any solution they feel works. I am always amazed at all the different ideas and creations that children come up with.

So grab a few materials and start building!

The list below includes some ideas that include several pictures and a full description. Other ideas include a link to click for a full and complete description.

#1 Popsicle Stick Bridge Challenge

This bridge building challenge is also a great introduction to STEM challenges. Children are simply given popsicle sticks and elastics. The challenge is to build a bridge that can hold weight.

To test these bridges, the popsicle stick bridge is set across two chairs, or tables, and then weight is applied. You can add to this challenge by making different requirements. Some ideas include:

  • Specifying the length of the bridge
  • Limiting the number of popsicle sticks and/or elastics
  • Making a height requirement

Depending on the age of the children, the bridges will likely look different. Some children may show their understanding of the shapes used to make bridges, or the strongest shapes, such as triangles. They may incorporate this information into their building. It is a great opportunity to use and test this knowledge.

#2 Building Blocks STEM Bridge Building

Another really simple STEM challenge is this building blocks bridge. Simply give children plastic building blocks and a sheet of blue paper for this “Build a Bridge STEM Challenge“.

This is a great challenge because, similar to the first challenge idea above, it uses simple materials that children are already familiar with. Children likely already know how to build with and connect the pieces.

It is also a great challenge because if your children are anything like mine, they already love building with the blocks. This interest will keep kids engaged and excited about the STEM challenge.

Have children set the sheet of paper down flat and ask them to pretend that it is water or a stream. Next, challenge them to create a bridge that can go from one side to the other without touching the water, or falling in the water, and they can only use the building blocks.

This was great when I did it with children in kindergarten. No two bridges were the same!

#3 Bridge STEM Challenges

Hang onto the building blocks from the last challenge for this STEM activity. Challenge the kids to build a bridge that can hold a can of food – or several cans! There are different ideas for the materials that children can use to build with.

It’s a simple idea, but a great way to keep kids busy and problem solving as they play. Click here to view the full Hold a Can Bridge Building Activity.

#9 Play Dough Bridge Building Challenge

My kids always love playing with play dough. I wanted to incorporate their interest in this building material by using the play dough and popsicle sticks for a STEM challenge. It is an easy STEM challenge to give children because it uses familiar building materials that you probably already have on hand.

I used this activity in the fall and children were challenged to build a bridge over a ‘stream of water’ (a sheet of blue construction paper), to get a few mini pumpkins from one side, back to the pumpkin patch. My students came up with countless solutions to this STEM challenge!
