Which do you think would have the greater volume and mass? Why? • 1 kg of feathers • 1 kg of rock 1 tonne of feathers will balance 1 tonne of Lead

Mass of 1 cm 3 of different materials

Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume.

Proof that water and ice have different densities

To find the density 1 - Find the mass of the object 2 - Find the volume of the object 3 - Divide Density = Mass Volume

Units for density Formula: M = mass M=Dx. V 3 g/cm or g/ml V= volume D = density V=M/D D=M/V

Dimension One Dimension (Length) Two Dimensions (Area) 3 Dimensions (Volume)

To find density: 1) Find the mass of the object 2) Find the volume of the object 3) Divide : Density = Mass - Volume Ex. If the mass of an object is 35 grams and it takes up 7 cm 3 of space, calculate the density.

To find density: 1) Find the mass of the object 2) Find the volume of the object 3) Divide : Density = Mass - Volume Ex. If the mass of an object is 35 grams and it takes up 7 cm 3 of space, calculate the density. Set up your density problems like this: Given: Mass = 35 grams Volume = 7 cm 3 Formula: D = M / V Unknown: Density (g/ cm 3) Solution: D = 35 g/7 cm 3 D = 5 g/cm 3

Do it yourself: Calculate the density of the following two sample of blocks

What Did we Learn 1. Density is the measure of how light or heavy a material is. 2. Density is a property of a material regardless of its shape & size. 3. Density is the mass of 1 cm 3 of a material. 4. To measure the density of a material, we need mass and volume. Density = Mass / Volume
