Density

A Physical Property

Density is the amount of “junk” something has in it.

• So…..Just by looking at the super ball, beach ball and the basketball, which would be more dense?

Okay, so what really is density?

• Density relates to how much mass of a material is in a given amount of volume (density = mass/volume).

• Who was the first to figure out Density?• Archimedes

And the story goes something like this?

Volume

• In science, we usually measure volume in Graduated Cylinders or beakers.

• Volume is the amount of space something takes up.
