We discovered last time we did this unit that water bottles make great pontoons! Sebby was fascinated with all kinds of bridges at the time, so we went much more in-depth in our bridge and army engineering study than we might otherwise have. While I don't currently have anyone quite as obsessed as Seb was, spending an afternoon at the little creek building bridges is great fun for anyone!
Here are a couple videos about modern Pontoon Bridges:
We split into teams so that each team could build their own bridge. I let them figure out their own designs and how to construct them!
Gus fell in the water almost immediately, of course. Luckily it was a hot day.
Daisy and Junie's first bridge was great! Strong enough to hold several marching soldiers.
Gus soon cheered up and was happily showing me how the cut on his toe was "almost better."
Daisy and Teddy tried a different bridge design, which worked maybe even better too. It was good to have some space between the pontoons for the current to go by and put less pressure on the bridge.
Their bridge was also nice and long!
The soldiers were able to sneak over to the enemy camp for a surprise attack!
Goldie and Junie tried a second bridge after seeing Daisy and Teddy's.
It was very sturdy!
