Josie partially filled a graduated cylinder with water. She then dropped a rock into the water. The illustration below shows what happened to the level of the water inside the graduated cylinder. Which property of matter is Josie measuring?

• Mass
• Length
• Weight 
• Volume

Alisa placed a small seashell on the pan of a balance. What other tool does she need to determine the density of the seashell?

• Scale
• Calculator
• Thermometer
• Graduated Cylinder

How can you find the density of an irregular shaped object?

• weight then volume using a graduated cylinder
• weight then volume using a ruler and the formula v=l x w x h
• mass then volume using a graduated cylinder
• mass then volume using a ruler and the formula v=l x w x h

How do you calculate density?

• multiply mass times volume
• divide mass by volume
• add mass and volume
• subtract mass and volume
