1. The make up and structure of all matter!!!
Density
The make up and structure of all matter!!!

2. Anyone Ever Tell That You’re Dense?
Well, you all are…
Because you all have these two properties
You are made up of matter…which means you have MASS
You all have VOLUME…which means you take up space

3. When You Combine Mass and Volume, you get…
Density
A measure of the amount of matter that occupies a given amount of space
SPACE
Amount of Matter
DENSITY DOES NOT CHANGE!

4. Wood Wood Size and Shape Do Not Matter… Wood
As long as the type of material (wood)
stays the same…so will the Density.
Regardless of shape or size.
Wood

5. So now you’re gonna say we need more units, right?
Even An Equation M
Units for Density =
Grams per
cubic centimeter
g/cm3
D = V

6. What Do All Those Letters Mean?
Density
M =
Mass
V =
Volume

7. Quick Visual Aid M D V

8. Wanna See An Example Question?
An unknown object has a mass of 15.0 grams and a volume of 5.0 cm3. What is the density of this object?
Density = Mass ÷ Volume
Density = 15.0 grams ÷ 5.0 cm3
Density = 3.0 g/cm3

9. Your Turn!!!
An unknown liquid has a volume of 6.0 cm3 and a mass of 6.0 grams. What is the density of this liquid?
Density = Mass ÷ Volume
Density = 6.0 grams ÷ 6.0 cm3
Density = 1.0 g/cm3
GOOD JOB!!!

10. How Can We Compare Densities?
Well…there are a known set of densities on record throughout the world
Density of Water =
1.0 g/cm3
Gives Us Buoyancy

11. Buoyancy Sinks Floats An object’s ability to float in water
Density Greater than 1.0 g/cm3 =
Sinks
Density Less than 1.0 g/cm3 =
Floats
