The document discusses why primary teeth fall out. It notes that children in P5 class are starting to lose their first teeth. The reasons for this include making space for permanent teeth to grow in around ages 5-6, having cavities where the tooth needs extraction, or breaking a tooth. The class tracks the teeth falling out of different students. They learn about tooth types, proper brushing to prevent cavities from sugar, and the importance of teeth for speech.
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.
