It was out turn to host Co-op this week and we did Bridges and Engineering. First we learned about why we need bridges, what makes a good bridge, the three types of bridges and what makes some bridges fail. Then we looked at some of the most famous bridges in the world on the internet. Then we built bridges or structures using a variety of textiles including Q-tips and rubber cement (they crate a flexible joint). We let the boys test them out to see how strong they were.
