Final answer:
Changing the material of a toy can affect its ability to float in water. Density and shape play a role in determining whether an object will float or sink.
Step-by-step explanation:
Yes, changing the material of a toy can affect its ability to float in water.
Floating and sinking are determined by an object's density and shape. If the density of the toy is less than the density of water, it will float. However, the shape of the toy can also affect its ability to float. Objects that have a greater volume and displace more water will experience a greater buoyant force and are more likely to float.
For example, a wooden toy may float in water because it is less dense than water and has a shape that allows it to displace more water. On the other hand, a metal toy may sink because it is denser than water and cannot displace enough water to experience a buoyant force.
