Understanding Relative Density

floating or sinking when compared to water.

• volume

• solution

• relative density

• mixture

Which property is this testing?

• relative density

• solubility 

• mass

• conductivity 

If you poured 3 liquids that do not mix how could you tell which one is the most dense?

• The liquid on top

• The liquid in the middle

• The liquid at the bottom

A bobber floats on the water because it is....

• more dense than the water

• less dense than the water

• the same density as the water

• to show you when you have a bite

Objects that are more dense than water will sink and objects that are less dense than water will float.

• Physical Change

• Properties of Matter

• Physical State

• Relative Density

A student observed two types of canned soda in a tub of water. What physical property of the soda did they observe?

• relative density

• solubility

• magetism

• thermal conductivity

Describe relative density-

• how dense something is compared with a reference material

• if something conducts energy

• sinks

• has magnetism

What is Relative Density?

• a substance or object that does not allow energy to flow through it easily

• anything that has mass and takes up space

• properties of matter that can be observed, measured, or changed without changing the matter itself

• floating or sinking when compared to water
