1. *HINT: Liquid Densities
HW: Finish density packet. Bring in a rectangular candy bar or healthy snack bar for tomorrow’s lab. CE#13-16 due Friday!
Do Now: /29/16
Take out your density Gizmo
Fill in the Gizmo data sheet using your completed gizmo
*HINT: Liquid Densities
Water = 1.0g/cm3
Oil= 0.9 g/cm3
Sea water= 1.03g/cm3
Gasoline= about 0.75g/cm3
Corn Syrup=1.37g/cm3
3) Get ready for current events

2. Current Events

3. Density Gizmo Gasoline, oil, water, sea water, corn syrup 0.8g/cm3

4. Did Everyone See the MAKERSPACE Commercial???

5. mass volume “stuff” Density Notes: Formula: Density = Mass
Density: the ___________of the material in a given _____________ (the amount of _____________ in an area).
Formula: Density = Mass
Volume
Units: g/cm3 OR g/mL
*(The more matter found in a particular area, the higher the density. Density never changes even if you cut something into 1000 pieces!!!)

6. Problem:
If a sample of rock has a mass of 120g and a volume of 60cm3, what is the Density of the rock?
Use the formula: D = M V
 Answer: ( don’t forget to show work and units!) 1 2 3

7. Density Practice Worksheet
Working with your lab partner, measure the mass and volume of a cube, then use that information to determine its density.

8. Page 36
The density of water is 1.0g/mL
The two different units you can use to represent density are g/cm3 OR g/mL
It is a physical property. Density is comparing the weight of a substance to the weight of water, and weight is a physical property.

9. D= M v
D= 116g
6mL
= 19.3g/mL 4 5
0.2
2000
They are both used to show units of density (g/cm3 OR g/mL).
