My kids want to learn about fish, but I know nothing about fish. Does anyone have anything about fish that they would be willing to share. I plan to start this in about 2 weeks. We don't have a shop or room in my classroom to make an aquaculture tank to raise fish in. I just want a quick 2-3 week lesson that would allow me to cover fish so that they will be happy and we can move onto other things that we need to cover.
