1. Do Now
Complete the first 12 questions on the handout called “Writing Meters, Liters, and Grams”
Remember “King Henry’s Dog Beethoven Drinks Chocolate Milk”

2. How to Construct a Line Graph
1. Independent Variable on the X axis, label with units.
2. Dependent variable on the y axis, label with units.
3. Determine the scale of the graph – (by 2, 5, 10 or more) Spread out the graph to use MOST of the paper. Count how many boxes you have and then compare to your range to determine what number to scale by.
4. Plot and connect the data points.
5. Title the graph.

3. Density Amount of matter within a given space of an object
How tightly, or loosely, packed the molecules are
More Dense = Tightly Packed
Less Dense = Loosely Packed
MORE DENSE
LESS DENSE 5

4. To calculate Density: Equation: Mass (g): Volume (cm3):
Triple Beam Balance
Volume (cm3):
Measure (L x W x H)
Water Displacement (Graduated Cylinder)

5. Density’s Label Density of Liquids or Gases: - g/mL Density of Solids:
- g/cm3

6. Example 1 What is the Density of the following Solid Object? MASScm
MASS
160.0 g
W = 2.0 cm
L = 4.0 cm

7. The lower an object floats, the more dense it is!
Relative Density
Floatation
Objects that are less dense will float on more dense objects.
The lower an object floats, the more dense it is!
Least Dense
Most Dense 12

8. Size of an object does not affect its Density

Indirect
RELATIONSHIP:
As temperature INCREASES, density DECREASES 15

10. As pressure INCREASES, density INCREASES
