Part II: Metric System Mania

BASIC UNITS
The basic units that correspond to a certain kind of measurement are:
LENGTH = _________ m
VOLUME = _________ L
WEIGHT (mass) = _______ g
Prefixes + base unit = metric system
Ex. centi + meter = centimeter

The 4 prefixes that we will use the most are
- kilo (k)
- centi (c)
- milli (m)
- micro ( or u)
Kilo Hecto Deca Basic Units Deci             Centi    Milli          Micro
Meter
Gram
Liter
Each step is either 10x larger or 10x smaller

CONVERSIONS
An easy way to move within the metric system is by moving the decimal pt
one place for each “step” desired

Ex. change meters to centimeters
1 m = 10 dm = 100 cm

If you move to the left in the diagram, move the decimal point to the left.
If you move to the right in the diagram, move the decimal point to the right.

LENGTH
1. What is the basic unit for length? ______________
2. Circle the best unit for measuring each distance:
a. Thickness of an eyelash: mm cm m
b. Length of a pencil: cm m km
3. Use a meter stick or metric ruler to find each measurement.
a. Width of this page ____________ mm or ____________ cm
b. Length of an unsharpened pencil _____________cm
4. Convert the following measurements:
a. 34 mm = _______ cm b. 3 km = _______ m
c. 234 cm = _______ m d. 35 m = _______ mm

MASS
WEIGHT: the force which gravity attracts a body
MASS: amount of matter an object contains (doesn’t matter on location on
planet)

W = mg
Weight = (mass) (acceleration on body by gravity)

5. What is the basic unit for mass? ______________
6. Circle the best unit for measuring each mass:
a. Amount of spices in a batch of cookies: mg g kg
b. Your mass: mg g kg
c. Mass of 10 pennies: mg g kg
7. Use an electronic scale to find each measurement.
a. Mass of an ink pen __________ g
b. Mass of a tack __________ g
8. Convert the following measurements:
a. 16 mg = _______ g b. 4.7 kg = _______ g
c. 12,345 g = _______ kg d. 2 g = _______ mg
TEMPERATURE
Temperature is the measure of heat intensity, or the hotness or coldness of
a substance.
U.S. uses Fahrenheit: 85°F
Rest of world uses Celsius: 30°C
Some scientists use Kelvin: 303K
(most scientists use Celsius)

°F = (1.8 X°C) + 32        ˚C= (˚F-32)/ 1.8

9. What is the basic unit for temperature? ______________
10. What are the freezing and boiling points for water on this scale?
_______ _______
11. Circle the best choice:
a. Temperature on a hot summer’s day: 0°C 35°C 90°C
b. Room temperature: - 20°C 0°C 20°C
12. Convert the following measurements.
a. 90°F = ______ °C b. 45°C = ______°F
c. 860F =_______°C d. 40°C = ______°F

VOLUME
3
1 mL = 1 cm
cm3 is pronounced “cubic centimeters.” It can also be abbreviated “cc.”
Hence, 1 cc = 1 mL (You see cc in the medical field)

13. What is the basic unit for volume? _______________
14. Circle the best unit for measuring each volume:
a. Amount of soda in 1 can: mL L
b. Water in a bathtub: mL L
15. Determine the volume for each object.
a. Use L x W x H to find the volume of a textbook ___________ cm3
b. Use water displacement to find the volume of 10 pennies
____________ ml or ___________ cm3
16. Convert the following measurements:
a. 160 mL = _______ L b. 23 kL = _______ L
c. 456 cL = _______ mL c. 120 mL = _______ cm3
TIME
17. What is the basic unit for measuring time? _______________
18. How many seconds are in:
a. 1 minute? _______ b. 6 hours? _______ c. 2 days? _______

DENSITY
DENSITY = MASS
VOLUME
- Mass per unit volume

Density is an intensive property of matter: it is the same regardless of size

19. If tap water has a density of 1.0g/ml, would the objects with the
following densities float, sink, or remain suspended in tap water?
a. 0.85 g/mL ______________ b. 1.0 g/mL _______________
c. 1.4 g/mL _______________ d. 0.92 g/mL _____________

GRAPHING

Definitions you need to know:
Independent variable: experimenter is free to choose its level.
Plotted on __ -axis.
Dependent variable: variable whose changes are explained by another
variable.
Plotted on __-axis.
Mean: Average. Sum of terms / # of terms.
Range: Maximum – minimum

Example
Kg of           # of tomato
fertilizer      plants
0               50
1               60
2               72
3               75
20. In this example, what is the independent variable? ________________

21. What axis would you plot this variable on? ______________________
