Project Idea
Using just a single sheet of paper (8.5 × 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

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Project Idea
Predict how tall you can build a tower using only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can tear, bend, cut, or fold the newspaper. Try it out and see how close you can come to your prediction. Can you beat your prediction? As you're building, you may come up with ideas to make a better tower. Try them out! (It's not like the materials are expensive!) Here are some variations you might want to… Read more

Research the famous collapse of the Tacoma Narrows suspension bridge. What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis. Read more

Project Idea
Maybe somewhere in your home there's a long hallway or a stairway with a light that you can turn on from either end. It's a nice convenience, but did you ever wonder how it's wired up to work that way? The goal of this project is to build a similar circuit with switches, flashlight batteries and a flashlight bulb (obviously, household circuits are not safe to experiment with). You'll need to understand the difference between connections made in series and connections made in parallel in an… Read more

Project Idea
thumbnail 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

thumbnail Alternative energy sources are a big deal these days. One such source is the wind. Find out how a wind turbine can use the power of the wind to generate energy in this science fair engineering project. You'll design various blades to find out which produces the most energy, and put the wind to work for you! Read more

Project Idea
thumbnail A bridge collapse, like that of the I-35W Mississippi River Bridge shown below, 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. #* IMG 1 *# Figure 1. On August 1, 2007 the I-35W Mississippi River Bridge collapsed killing 13… Read more
