We're here to help you navigate STEM learning at home while schools and camps are closed due to COVID-19.

Here are some resources to guide your at home learning:

Investigate what makes a strong and stable bridge design. Build and test a paper bridge, or use a free online tool to create bridges that can stand during earthquakes, or design trusses (frameworks to support bridges).

Bridges are big and beautiful structures, but they also need to be safe for the people who cross over them every day. Building a bridge that is safe and secure is a challenge to civil engineers. But the job is even more challenging if you live in earthquake country! Find out how engineers are solving this problem as they build a new bridge over the San Francisco Bay in California. Try some of your own Bay Bridge designs. Will your bridge design take the shake of a quake? Read more

Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more
Science Fair Project Idea
Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails… Read more

Build model bridges and then deliberately destroy them? Who'd be crazy enough to try that? Read more

A bridge collapse, like that of the I-35W Mississippi River Bridge, can be a major disaster. Bridges that cannot hold enough weight to do their intended job can be a serious public safety issue. And if they collapse, they can also cause economic damage due to costly rebuilding and people and companies scrambling to figure out how to circumvent the months of traffic impacts. Figure 1. On August 1, 2007 the I-35W Mississippi River Bridge collapsed killing 13… Read more

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online simulation software to analyze the distribution of load-bearing forces in each design. Then you'll build and test prototypes of each design.
