Inquiry Question: How can teachers communicate between classrooms without electronic devices.
I would create an inquiry as to how teachers could communicate with teachers from other classes efficiently without having to go to that classroom to speak to them. This would work well with speaking to other teachers in the same grade level. The students would need to create a communication system that does not require electricity to communicate. A satisfactory end goal would be creating a cup and string telephone running between the two classrooms or possibly a mail shoot system.
The inquiry would start off by introducing systems. The students would then be given the scenario that all power stations were broken and the teachers need a way to communicate from far away. Teachers could then provide options and the class must design and create the solution.
