1. Measurements
The Metric system was developed in France during the Napoleonic reign of France in the 1790's.

2. “Weights and measures may be ranked among the necessaries of life to every individual of human society…They are necessary to every occupation of human industry.... The knowledge of them, as in established use, is among the first elements of education...”
JOHN QUINCY ADAMS - Report to the Congress, 1821

3. Which other countries, besides the U.S., do not use the metric system?
STAT FACT
Which other countries, besides the U.S., do not use the metric system?
Only a few small countries (Liberia and Myanmar) , including some Caribbean nations heavily influenced by the U.S., have not formally adopted the use of SI.
Among countries not claiming to be metric, the U.S. is the only significant holdout.

4. In any measurement system,It… must be agreed upon and cannot change
Ex: The foot.

5. Le Systeme Internationale d’Unites (SI)
1960- SI system
Based on Metric System

6. Standards 5
In a measurement system there are exact quantities that people agree to use for a certain measurement.
Ex: The meter
The speed that light travels in a vacuum 1/ of a second.
Why...This seems CRAZY!!!

7. Another Example of a Standard …..The kilogram
The official kilogram, made of platinum-iridium, remains in France at the International Bureau of Weights and Measures

8. Le Systeme Internationale d’Unites (SI)
English: International System of Units
Each measurement has a base unit.

9. Based on multiples of ten.
SI System
Based on multiples of ten.
Examples of base units
Length
Meter
Mass
Gram
Volume
Liter
Time
Second
Temperature
-Kelvin
Energy
-Joule
Electric Current
-Ampere

10. Base Units
EX:
1 Liter= 1000ml
1 gram = 1000mg
1meter= 1000mm

11. Based on Multiples of TEN
Prefixes
Prefixes are used with the base units to indicate what multiple or fraction of ten should be used.

12. Metric Conversions
A conversion is changing the way you state the same amount!
Ex: 1 dollar
4 quarters, 100 pennies, 10 dimes
1meter = 100centimeters
Simply move your decimal point.

13. Laboratory Apparatuses for making Measurements

14. LENGTH
Distance

15. Meter Stick 1m = 100 Centimeters 1m = 1000 millimeters
Length
Distance
1m = 100 Centimeters
1m = 1000 millimeters
1cm = 10 mm
Each line on the meter stick is a millimeter.

16. Meter Stick
The last digit in all measurements is an estimate digit.

17. Amount of matter in an object
MASS
Amount of matter in an object

18. Triple Beam Balance Grams

19. Space occupied by an Object
VOLUME
Space occupied by an Object

20. Length x Height x Width =Volume

21. Graduated Cylinder

Space an object occupies

25. TEMPERATURE
Kinetic Energy

26. Temperature Fahrenheit vs. Celsius vs. Kelvin
Absolute Temperature scale
Lord Kelvin ( )
1742, Anders Celsius ( )

30. Starter: How many ml are in 1 kl?
If I have L, how many ml do I have?
What is a standard?
What are some units for volume? (give 2)
What is an independent variable?
What is mass?
Marsha has three 2-L sodas. How many ml does she have total? If there are six people at dinner, how many ml can they each have (and it be equal amounts)??

31. DENSITY
Mass per unit Volume

32. Density Density: Amount of matter in a specific volume.
These 2 cubes have the same VOLUME, but they have different densities. Why?

33. Density practice problem
Which cylinder has the greatest density?
So, if I had the same amount of each cylinder (1 ml), which one would have a greater mass??
Vol: 5 ml
Mass: 10g
Vol: 25 ml
Mass: 15 ml
Density = 2 g/ml
Density = 1.7 g/ml

34. Derived Units Obtained by combining different units. Ex: Density30
Obtained by combining different units.
Ex: Density
Density is the amount of mass per unit volume.
D = m/v

35. TYPES OF DATA Quantitative vs. Qualitative31
TYPES OF DATA Quantitative vs. Qualitative
If the data collected involve observations without measurements or numbers, then it is referred to as qualitative data.
Quantitative data involves numbers or measurements.
