Video highlighting the top three bridges from the Maine Transportation Conference Popsicle Stick Bridge Contest. These bridges are quite impressive, with the winner holding 1278 pounds before breaking. The commentary on this video contains useful observations and thoughtful opinions from the video makers.
Here is the model bridge featured in my ebook, 5 Steps to Building a Model Bridge. This is the bridge seen in the photos of the step by step process of bridge construction. This video shows the last bit of the testing process in which the bridge comes to an explosive end
The Arizona Science Lab presents information on types of beams used for building bridges. They show the huge difference in resistance to bending between a flat beam and an I Beam. Then different types of truss designs are shown and explained. Afterwords the students are given supplies to build their own bridges, and this video highlights some of them. Their goal is to make a bridge which holds 50 pounds over a 2 foot span. Their materials are popsicle sticks […]

I like this video because it is pretty clear why each bridge failed. Can you see a major design issue that could be improved in most of these bridges? Notice that they do incorporate triangles, but they are missing a key member. The students were only given Cardstock Rubber […]
This video has some excellent toothpick bridges. These bridges hold an incredible amount of weight before they break. You get to see it all on video
