A Bridge Too Far?

Grade 7/8 straw bridgeGrade 7/8 straw bridge

The grade 7/8 science class at Foremost School is learning about structures and forces. In order to put the theory to work in a practical setting they constructed bridges of their own design using only drinking straws, paperclips and tape.

Working in groups they were give a set amount of materials to construct their design. The parameters were that it had to be at least 30cm long, be at least 5cm above level and transport a golf ball unassisted from one end to the other.

There were a lot of excitement during the design and construction phase, however, some trepidation when it came to the testing phase. No one wanted to volunteer their bridge to go first. They started second-guessing their designs.

Some of the bridges were successful and others were not quite as successful. The students all had ideas about how they could have improved their bridges and that was what this lesson was really trying to show them.

One day maybe one of these students will design a real bridge that you will someday travel. That would be outstanding. I hope they use something stronger than drinking straws for that bridge.
