### SI UNITSA Logical Way to Measure!

A number alone is meaningless:

5 blocks from Here?

Meet me in 5….

5 Minutes?

I. Standard Units of Measurement
• Systeme International – we let the French name it
• BASE 10 system –
• 10, 100, 1000 etc.
• based on metric system
METRIC CONVERSION (STAIRCASE METHOD)

To convert to a smaller unit, move

decimal point to the right

Kilo

1000

units

Hecto

100

Deka

10

milli

0.001

units

To convert to a larger unit, move

decimal point to the left

Remember?

“King Henry Died by drinking chocolate milk”

(Kilo) (Hecta) (Deca) (base) (deci) (centi) (milli)

Derived units
• Multiply or divide standard units.
• Exs:
• Volume:
• cm3
• Density:
• grams/cm3
Graphing
• Visual display of information or data
• Type used depends on type of data

I) Line graph

• Show trends or changes over time
• Independent variable on the x-axis (horizontal)
• Dependent variable d on the y-axis (vertical)

II) Bar graphs

• Compare counted information
• Bars not connected (discrete)

III) Circle graph

• Show how some quantity is broken down into parts
Exs:
• DATA: # freshman, sophomores etc. at KHS in 2009
• GRAPH:
• BAR
• DATA:# of freshman, sophomores etc as percent of total students at KHS in 2009
• GRAPH:
• CIRCLE
