1. Bell Work:
Pick up a bell work handout and glue it on page 44…Title it MATTER VOCABULARY.
Look over the handout and try to memorize the new key terms!
Read the definitions and add a picture to help you remember each one.

2. On Friday… You learned all about volume…again!
What’s the formula for volume?
When would you use the formula to find an object’s volume?
How could you find the volume of a rock?

3. All About Volume!
Water Displacement

4. All About Volume!
10 g/cm³

5. All About Volume!
40 g/cm³

6. All About Volume!
2 g/cm³

7. Physical Property of Matter
Density
Physical Property of Matter

8. Today’s Goals… Know the formula for finding an object’s density.
Identify the particle arrangement for objects that are very dense versus those that are less dense.
Explain a density column.

9. Density Formula:
DENSITY = mass/volume D =

10. The closer the molecules are, the denser the object it.

12. Water has a density of 1.0 g/cm³.
Will it sink or float?
If something is less dense than the liquid it’s placed in, then the object will float.
Water has a density of 1.0 g/cm³.
So…if an object has a density of 1.5 g/cm³, then the object will sink.

13. Density Column:

14. Density Column:

15. Let’s Practice…
Marble: 50 g; 5 cm³
10 g/cm³

16. Let’s Practice…
A 10.0 cm³ sample of copper has a mass of 89.6 g. What is the density of copper?
8.96 g/cm³

17. Let’s Practice…
A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block? Hint: Don’t forget to find the volume of the wood first.
1.0 g/cm³

18. Let’s Practice…
An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2 ml. The height of the water rose to 7 ml. If the mass of the stone was 25 g, what was its density?
5 g/cm³

19. Benzene Let’s Practice…
Five ml of ethanol has a mass of 5.0 g, and 5.0 ml of benzene has a mass of 45 g. Which liquid is denser?
Benzene

20. At the lab table…
Find the density of the three objects: 1) Clothes pin 2) 5 pennies 3) Wood block Record your data on an index card. Clean up thoroughly and turn in the card. Pick up the density worksheet.
