Methods for Calculating Density
Calculating Density
 Remember, Density = mass/volume
 Mass is determined using a scale
 Volume is calculated several different
ways
Finding Volume
 To find the volume of a
liquid, use a graduated
cylinder
 Make sure to read the bottom
of the meniscus
Finding Volume
 Length x Width x
Height
 Volume of a regular
object, such as a
wooden block
Finding Volume
Water Displacement Method
- Read the initial volume of water in a
graduated cylinder
- Place object into cylinder
- Read the final volume of water
- Final – Initial = Volume of the object
Density Water Displacement Lab
Ms. Ose will assign lab groups
Lab Safety/ Clean Up
 No closed toe shoes or aprons are required
 If you spill, clean the water with a paper towel
 When you finish collecting data, return the lab area as you
found it
Density Practice
When you finish the lab activity begin working on
the Density practice problems. Whatever problems
you do not finish will become your homework.
Exit Ticket
