METRIC SYSTEM NOTES

A.     Linear Measurement ( distance )

-         To find out the length, width, or height of an object

1.    The main unit is the meter ( m )

2.    For a long distance use the unit kilometer ( km )

3.    For a short distance use the unit millimeter ( mm )

 

B.     Liquid Volume

-   How much space a liquid takes up

1.     The main unit is the liter ( l )

2.     For a large amount of liquid use the unit ( kl )

3.     For a small amount of liquid use the unit ( ml )         

 

C.     Mass ( weight )

-         To find out how much matter something has

1.    The main unit is the gram ( g )

2.    For a heavy object use the unit kilogram ( kg )

3.    For a light object use the unit milligram ( mg )

 

D.     Scientists use the Metric System instead of the English System because:

1.     It is easier.

a.     The units prefixes are the same for Linear Measurement, Mass, & Volume and easier to remember

1)    milli, centi, deci, deca, hecto, kilo

b.     The numbers are the same

1)    1, 10, 100, 1000

c.     The numbers are easier to use

1)     move the decimal to the left or right rather than divide or multiple by fractions

 

E.     The whole world uses the Metric System except for the U.S., Myanmar, & Liberia.

F.      The Metric System is the official measuring system for the U.S. for over 200 years.

METRIC SYSTEM – Temperature

Temperature – A measure of how hot something is

A.     The Celsius scale is used to measure temperature in the Metric System.                                                   English System

·        boiling point = 100   C                              212   F

·        freezing point = 0   C                                 32   F

·        room temperature = 20   C                        68   F

·        body temperature = 37   C                      98.6  F

1.     A negative sign in front of the number shows when a temperature is below freezing.  Ex.  – 12  C

2.      A thermometer is the instrument used to measure temperature.

 

B.     Temperature scale conversion

1.     Celsius to Fahrenheit                          Ex.  C = 10

a. Copy over the equation    Equation    F = (  C X 9) /5 + 32

b. Rewrite the equation,

but put in the number        Substitute  F = (10 X 9) /5 + 32

c. Multiply then rewrite the rest Solve   F = 90 / 5 + 32

d. Divide then rewrite the rest                 F = 18 + 32

e.  Add                                                          F = 50

 

C.     Temperature Activity:

1.     What is the temperature of the air in the room?

2.     What is the temperature of the water?

3.     What is the temperature of the water after ice is added?

4.     What is the temperature of the hot water?

5.     Write down five degrees celsius

6.     Write down five degrees below zero celsius
