We learned about homeostasis and positive and negative feedback cycles, and then I had the children design a machine using the principles of homeostasis. I am fairly sure these wouldn't work in real life, but they looked really cool and I had fun listening to the boys tell me about them. :)

Here is a video about homeostasis.
