The students in class P-4B studied fish and shared what they learned. They explored how fish live in water, breathe through gills, are covered in scales and propel themselves with fins. The students measured different fish, observed how objects float and sink in water, and learned that fish have an air bladder that allows them to float. They also discovered that most fish lay eggs and the young develop into small fish called fry. The class enjoyed learning about fish and was grateful for help from parents.
