How many kinds of tropical fish are there? Why are they called tropical fish? Are all tropical fish so bright and colorful? Do all tropical fish live in reefs? What is a reef made of? What is an artificial reef?
So many authentic driving questions. A great authentic project might be to design an artificial reef. This could incorporate many science and math goals. Another authentic project might be to create and take care of a tropical aquarium. (Or not – fish never did well in my classroom – I’m better with plants!)
