Hi...Dear..!! I will explain you about it !!
BUOYANCY :
The tendency of something to float in water or other fluid.
WHY DOES IT FLOATS / SINKS :
It depends on the object’s density. Density is the mass (weight) of an object divided by its volume (size).
An object which has a lower density than water (1 gram per cubic centimeter, or 1,000Kg per Cubic Meter) will float.
EXAMPLE : a block of steel will sink because it has a density of 8050Kg/cubic meter. Bamboo wood floats because it has a density of about 300.
( This is the reason to float / sink )

Buoyancy is an object’s ability to float in a fluid. This is caused by Upthrust, or a Buoyant Force acting on the object which is equal to the weight of the fluid it displaces, according to Archimedes’ Principle.
When the object has density less than 1 gcm3, then it floats on the surface of water, because. it always displaces more weight of water than its own weight. As buoyant force is more than its own weight, therefore, it floats.
When the object has density more than I gcm3, then it sinks in water, because, it always displaces less weight of water than its own weight. As buoyant force is less than its own weight, therefore, it sinks.
