1. oneone CS-6C Objective: To measure the mass and volume of an irregularly shaped solid in order to calculate its density. CSI Note: Can you apply what you know to find the density of solids? HAVE YOU FOLLOWED THE STEPS FOR STARTING CLASS?? Drill: 1. Get a Lesson Sheet from the SET. 2. Complete the Drill portion only.

2. oneone CS-6C Examine the objects in the bag in your tote. Predict the density of each object in your Drill Book. How did you come up with your predictions?

3. oneone CS-6C Density = Mass ÷ Volume

4. oneone CS-6C Discussion Question How can you determine the density of your objects? a.Think b.Small Group Discussion c.Open Discussion

6. oneone CS-6C Lab Experiment: The Density of Solids

7. oneone CS-6C Get Materials One Way Street Cup of Water Graduated Cylinder Skim Procedures

8. oneone CS-6C 1. Record the name of the object in the data chart.

9. oneone CS-6C 2. Zero the triple beam balance.

10. oneone CS-6C 3. Place the solid on the triple beam balance, and determine its mass.

11. oneone CS-6C 4. Record the mass in the data chart. (2)

12. oneone CS-6C 5.Using a cup, add between 30mL and 60mL of water to the graduated cylinder.

13. oneone CS-6C 6. Record the volume of water in the data chart as your starting volume. (4)

14. oneone CS-6C 7. Carefully slide the object into the graduated cylinder.

15. oneone CS-6C 8. Record the total volume in the data chart. (3)

16. oneone CS-6C 9. Calculate the object volume by subtracting the starting volume from the total volume. (3 – 4)

17. oneone CS-6C 10. Record the object volume in the data chart. (5)

18. oneone CS-6C 11. Calculate the density of the object by using the formula. (2 ÷ 5)

19. oneone CS-6C 12. Record the density in the data chart. (6)
