Bridges made from popsicle sticks is a STEM activity for kids that will put their science, technology, engineering and math skills to the test in a playful way. These popsicle bridge ideas are great at home or in the classroom. An arch bridge with popsicle sticks can be a fun and easy project for kids and adults alike. It can serve as a simple introduction to the concepts of trusses and bridge-building, or as a challenging exercise in design and engineering. The box girder bridge design is less common than the truss and beam bridge designs, but it can be a good option for certain applications.
Step 2: Why a Warren Truss Pattern?
Use scissors to make the popsicle sticks the desired length. Next, glue the sticks together, creating the shape of the arch, and secure the structure by adding a crossbeam at the bottom. Here’s another fun video tutorial to build a truss bridge with popsicle sticks – a classic science project. You’ll be surprised by the strong shape of your own bridge. I used Instructables to search what types of bridges people were building. I used this to help me figure out which type of bridge I wanted to build.

I added the cross beams so I could add some more popsicle sticks along the sides at the top (in third photo). I added those so I could make some beams that were horizontal and on its edge. That would increase the weight it can hold. I connected three triangles at the base by putting popsicle sticks on both sides to make it as strong as I possibly could.

In 1850, Squire Whipple designed the first Warren truss bridge in America. Building popsicle stick bridges is one of my favorite activities to do in my spare time. I have built many popsicle bridges over the years, and love coming up with new designs. A huge focus of my bridges is designing blueprints that are easy to build and structurally sound at the same time. You can purchase many of my plans and blueprints in my store. It is about eighteen inches long and five and a half inches high.
We recommend this project is great for age 10 and up – younger kids will love it too, but may need more help from a parent or teacher. Just follow the step by step directions to build a Da Vinci Bridge. Connect the sides by gluing (using hot glue) the sticks following the pattern. Apply hot glue on points shown in the middle right and bottom right pictures.
Step 9: Add Stick 16
Add a seventh stick (orange one) by sliding it underneath the two red sticks. The bridge is strong when it comes to downward force but lateral force (from the sides) may cause it to topple. Moving the bridge while it stands (even slightly) could cause it to fall apart, so be careful.

This tutorial from Science Project Ideas includes easy steps to build a bridge and test it with small weights. You will then make two more with just two popsicle sticks making shorter beams. These are going to make the trusses and will form triangles. Using a 3-stick beam and a 2-stick beam that has mostly dried, attach them with the sticks making a triangular pattern.
Then glue the struts and braces across the top and bottom. (Struts are braces that meet the chords at 90° angles.) It’s essential that the trusses are exactly vertical, perfectly perpendicular to the struts and braces. Even a small amount of leaning will cause your bridge to fail prematurely. The long top and bottom members of the truss are called chords. The slanted members that tie the chords together are webs.
Connect the top and bottom of the structure. Glue 1/3 pieces to the middle of the bottom stick (seen circled in blue in the picture on the top right) of each triangle with white glue. Glue down Popsicle sticks to connect the triangles together with white glue (specific alignments seen circled in red in the picture on the left). Take 3 Popsicle sticks and lay them out in a triangle shape. Attach an end of one side stick to an end of the bottom stick with hot glue (be sure to place the side stick at a 45 degree angle). The point where the two side sticks meet should not have the sticks overlapping, but rather side by side (This is shown circled in red on the top picture on the right).
We’re going to be making a Pratt truss bridge in today’s experiment, so the design will reflect that style of bridge. We have an activity that is perfect for the little kids in kindergarten! Not only is it a fun way to learn about how bridges work, but since it’s dinosaur-themed, kids between 3 and 5 years old will be more than thrilled to make it.
Now let’s learn about truss design and make a truss bridge from Makezine. They explain how they work which is very important in modern architecture, and then shared a tutorial to make the bridge using wood. After you finish your bridge completely, wait enough time to allow the glue to dry completely before you test the bridge. Sometimes you will want to test the bridge immediately, but your bridge will not hold as much weight if you test it before the glue has cured.
In our case, since we won’t be holding quite as much weight, it’s not as crucial. You can use markers or some project paint to color the popsicle sticks before you begin assembling the bridge. Follow this video tutorial to make an easy craft of mini bridge, without leaving your home. Making your own bridges is a perfect way to teach about civil engineering in a simple way. Get two triangles and turn one upside down (One triangle should have the bottom stick facing down while the other should be facing up).
I made it for a 7th grade class extension project. There was no height limits and has to hold one hundred pounds. For your bridge to hold one hundred pounds you must do a lot of research first. The main thing that I learned was that triangles are one of the strongest geometrical shapes, and the kind of glue that you use does matter. Popsicle stick bridges can be used as a fun and interactive way of learning about construction design projects for civil engineering students. These small-scale projects can help students understand the fundamentals of bridge design, such as types of bridges, their components, and their purposes.
Once they'd dried just enough to not fall apart, I moved on. If you are interested, you can purchase the blueprints to build this bridge in my store, and you can also buy a complete kit to build this bridge. These three photos show the progression of the bridge breaking. This update to a classic design brings more realism, but with a cost. To burnish wood, vigorously rub the workpiece with handplane shavings for a glass-smooth finish.
