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

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!

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

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

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

Quick Visual Aid M D V

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

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!!!

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

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
