Student Instructions
Using only two sheets of paper, build a strong bridge that will reach across a 6-inch gap. The bridge must be at least 3 inches wide. Using the attached "Bridge Designer's Notebook", design 3 different bridges - one at a time. 1. Think about bridges that you have seen. Can you make something that has the same shape out of paper? 2. Experiment! Make a paper bridge across the gap between two books. 3. Put pennies on your bridge, one at a time. Observe what happens when pennies push downward. 4. Keep adding pennies until the bridge collapses. 5. Record observations onto "Bridge designers notebook" 6. Reflect - think about how you could change your bridge so it's better at fighting the downward push. 7. Change your bridge and try again. 8. Build at least 3 different bridge designs. Keep track of your designs and data in your designer's notebook.
