This document discusses a class project about an irisated fish named Peix Irisat. The students take care of Peix Irisat, feeding it and changing its water daily. They also learned that fish can live in both saltwater and freshwater, as well as cold or warm water. The students observed Peix Irisat both inside and out, and discovered that fish come in a wide range of sizes. They role played being fish by making bubbles. Peix Irisat lost some scales, so the students helped it look for them.
