### Density

Measure the mass and volume of a variety of objects, then place them into a beaker of liquid to see if they float or sink. Learn to predict whether objects will float or sink in water based on their mass and volume. Compare how objects float or sink in a variety of liquids, including gasoline, oil, seawater, and corn syrup.

#### LEARNING OBJECTIVES:

• State the SI units used for mass and volume.
• Measure the volumes of irregular objects using water displacement.
• Discover that density can be measured.
• Predict whether an object will float or sink by measuring its mass and volume.
• Define the relationship among mass, volume, and density.
• Calculate the densities of irregular objects.
• Compare the densities of liquids.

#### VOCABULARY:

• density, mass, matter, volume
