When you drop a coin in a glass of water, it sinks, but when you place a bigger wooden block in water, it floats. Explain. Class 8

Answer:

A coin sinks in water because its density (mass per unit volume) is greater than that of water. A wooden block floats because its density is less than that of water, causing it to be buoyed up by the water.
