Mike & Elijah took their bridge to the bridge-buildng co-op class--it was a competition to see which bridges could support the most weight.

Here are all the bridges that the other families in the class made. There were so many different designs. It is interesting how 100 craft sticks can be modeled into so many different designs.

Each bridge had to span at least 12 inches. The bridge was set on two saw horses and then a bucket was wired through the bridge. Weights were added to the bucket. We had 84 pounds in free weights we could add. The kids added the weight to the bucket for their own bridge.







84 pounds and no failure. Elijah's bridge moved to the second phase of testing. The intention of the class was to build a bridge and add weight until it breaks. Well, we didn't have enough weight to break some of the bridges, so those bridges get to move to the next round to be held sometime in the future. (can you see that the weight was enough to break the BUCKET?!)
