What will happen to an object that is more dense than the fluid
it is in?
A. It will sink.
B. It will float.
C. It will rise to the surface.
D. It will bounce out of the water.

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.
