Very Simple Fridge Door Alarm

Hello everyone, could someone direct me to a schematic of a simple fridge alarm circuit/schematic that gradeschoolers could follow and implement. It doesn't need to be fancy, but it just needs to be working and something that you can use to show Electronic Principles.

 

Thanks for your time!
