Last week we made our own food chains, and as a class made a food web. Some of the food chains were life in a swamp, ocean and mountain, and there were others also. In the food web we each picked an animal and learned what it ate and what ate it. Next we each said what our animals ate and what ate it. Then we connected yarn from one of us to another.If our animal ate theirs or if theirs ate ours. then we would drop the strings one by one as they got eaten or overpopulated and starved. This made me realize that if one thing dies out, other things do too.
