description of what I did
I.D a problem and define it
The problem is to build a bridge that can support as many pennies as possible. We have to build a bridge out of 20 straws and tape, and have it support pennies. The other problem that could arise is the tape not sticking very well. That could ruin the whole project.
We thought of using a Truss bridge design for the problem. We decided to use that design because it would probable be the strongest, and the sturdiest. Also, if we tape it right the joints won't give out.
20 straws, tape, and pennies.
Testing and evaluating
We built a platform and added it to the structure. Then, we used a cup to hold all the pennies. Then, we started putting the pennies in 5 at a time.
