1. 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 Amount of Matter SPACE

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

5. So now your gonna say we need more units, right? Right!!!! Units for Density Units for Density = Grams per cubic centimeter g/cm 3

6. What Do All Those Letters Mean?

7. Quick Visual Aid

8. Wanna See An Example Question? An unknown object has a mass of 15.0 grams and a volume of 5.0 cm 3. What is the density of this object? Density = Mass ÷ Volume Density = 15.0 grams ÷ 5.0 cm 3 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 cm 3 Density = 1.0 g/cm3

10. How Can We Compare Densities? Well…there are a known set of densities on record throughout the world 1.0 g/cm 3

11. Buoyancy An object’s ability to float in water Density Greater than 1.0 g/cm 3 = Density Less than 1.0 g/cm 3 =
