testing bridges


We continue to progress through our Engineering is Elementary: Designing Bridges unit, this time testing out the strength and failure modes of various bridge designs. We tested three different designs, and then improved upon the strongest design to make it even stronger! Our strongest design, using just cardboard bricks as the abutments and card stock as the span, supported over 1 kilogram! Pretty cool.


Here are the three designs we tested:

 It was such a gorgeous day, that after building bridges and learning about Helen Keller, we had to go outside and play!
