For the last 3 months during IPC classes, 5th grade has been discussing the unit " Go with the flow" about rivers. We were talking about the elements of a river, the longest rivers in the world, the processes that shape rivers, the river as a habitat, and the technology connected with rivers: bridges, water wheels and dams.
However, the class decided that the best task was designing and “building” different types of bridges. The students did most of it in their free time. Just check them out. They are amazing.
Ah, these our little engineers :)
