What is an example of a dense material?

• Gold

• Lead

• Aluminum

• Wood

Objects that are less dense than water will

• sink

• float

• dissolve

• evaporate

These rocks will

• float.

• sink.

• dissolve.

• erode.

What is density?

• Density is the mass of an object divided by its volume.

• Density is the weight of an object divided by its height.

• Density is the volume of an object divided by its mass.

• Density is the mass of an object multiplied by its volume.

What is the formula for calculating density?

• Density = Mass + Volume

• Density = Mass - Volume

• Density = Mass / Volume

• Density = Mass × Volume

What happens to a rubber duck in water?

• It sinks because it is heavier than water.

• It floats because it is less dense than water.

• It dissolves in water.

• It changes color in water.

If an object has a density less than water, it will

• sink

• float

• dissolve

• break apart

Anything that takes up space is

• mass

• weight

• volume

• density

Why does oil float when poured into water?

• Oil is less dense than water.

• Oil is heavier than water.

• Oil has a higher boiling point than water.

• Oil is more viscous than water.

What does it mean if an object is neutrally buoyant?

• It sinks to the bottom of the fluid.

• It floats on the surface of the fluid.

• It neither sinks nor floats; it stays suspended in the fluid.

• It moves up and down in the fluid.
