What is density?

Density is a specific property of matter that is related to the mass divided by the volume

                                                   

Page 4: Aim: How do we calculate density?

What is the formula for density?

D = _Mass_

Volume

D = M

V

D = Density M = Mass V = Volume

Why does a penny sink in water?

Pennies are more dense than water, therefore they sink

Page 6: Aim: How do we calculate density?

Why does ice float in water?

Ice cubes are less dense than water, therefore they float

Page 7: Aim: How do we calculate density?

How will an egg float in water?

Egg in fresh water– The egg will

sink because it is more dense than the fresh water

Page 8: Aim: How do we calculate density?

How will an egg float in water?

Egg in salt water– The egg will

float because it is less dense than the salt water

Page 9: Aim: How do we calculate density?

How will an egg float in water?

Egg in fresh and salt water– The egg will be

suspended in the middle because it is the same density as the water mixture
