I have some great news to share! There is a replacement for the old Bridge Designer which no longer works on modern web browsers. The new pony in town is called the Truss Simulator. Like before, it is freely hosted on the Johns Hopkins website, and created by Claire VerHulst. This new Truss Simulator brings … Read more

Drew’s science fair was this past Friday, and he won a special award/ribbon for a “Superior” project. I’ve attached photos of he with his tri-fold board. He built/destroyed two bridges in order to prove his hypothesis, and so built a third (as seen in the photo) to show his classmates what they’d looked like. He … Read more

A bridge is just something that helps us cross an obstacle, whether that be a river, ocean, swamp, canyon, or highway.

Here is a short, fun video showing creative bridge designs from very limited supplies. These bridges were required to be under 5oz in weight, but only had to span 8 inches. I like this video because it is pretty clear why each bridge failed. Can you see a major design issue that could be improved … Read more
Balsa wood is unique from all other woods. Its properties make it valuable to bridge builders, wood carvers, surfers, and many others. Bridge builders have to be careful, however, when using Balsa. You can’t simply pick up two pieces of Balsa with the same dimensions and expect them to perform the same.
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 … Read more
