Exit Ticket

8. Methods for Calculating Density

9. Calculating Density
Remember, Density = mass/volume
Mass is determined using a scale
Volume is calculated several different ways

10. Finding Volume
To find the volume of a liquid, use a graduated cylinder
Make sure to read the bottom of the meniscus

11. Finding Volume Length x Width x Height
Volume of a regular object, such as a wooden block

12. 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

13. Density Water Displacement Lab
Ms. Ose will assign lab groups

14. 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

15. 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.

16. Exit Ticket
Which density problem was the most difficult?
