2. Système International d'Unités
METRIC SYSTEM
Developed in 1791 and is currently used almost everywhere in the world, except the US. Our scientists, hospitals, researchers, etc use this system.
Système International d'Unités 
International System of Units or SI 10
Based on the number

4. LENGTH
is the distance between 2 points.
The standard unit is the meter. 1m = 39.4 inches
Measuring instrument meter stick ruler
Smaller objects are measured using the cm cm =1 inch
100cm = 1m
Even smaller objects are measured using the mm.
Long distances = km
1 km = .62 miles
1km = 1000m

5. Volume Standard unit is the liter = l or L. Small amounts = mL
_______mL = 1 L
LARGE amounts = kl
The amount of space an object occupies.
________L = 1 kl
How many kl is 3250L ?
3.250kl
What instrument is used to find the volume of a liquid?
graduated cylinder

6. Graduated cylinder
When measuring liquid volume it is important to read the graduated cylinder correctly. You eye should be level with the top of the liquid and you should read the bottom of the meniscus.

7. You would read this as ________
                                                            
You would read this as ________

8.                                    
How may mL is showing in these graduated cylinders?

9. Volume of rectangular solids
Width = 5cm
Height = 4cm
length cm
Formula:
V = length x width x height
Find the volume of the box. 3
200cm

10. VOLUME
What would the volume of a cube that has the l = 1cm, w = 1cm, and the h = 1cm be?
1cm3
A 1cm3 hollow cube holds __ml of H2O, therefore 1000cm3 = ____ ml or 1 ___

11. The amount of matter in an object.
MASS:
The amount of matter in an object.
Instrument used to find mass:
Triple beam or electronic balance
Standard unit is the kilogram kg
Common unit - the gram. A large paper clip masses about 1g.
Extremely small items are massed using mg for the unit.
1 g = _____ mg. How many mg would = 1kg?

12. What is the mass on the balance?

13. Triple Beam Balance The weight of a can of Diet DEW is?
                                                                                         
______________________

14. Weight A measure of attraction between two objects due to gravity
Standard unit = Newton (N)
A 1kg object is pulled to Earth at a rate of 9.8 newtons, so the weight would = 9.8N Weight = mass x 9.8 newtons (on Earth at sea level).
Note gravitational pull would be less on a mountain than at sea level, because you are farther away from the center of Earth.

15. DENSITY The amount of matter that occupies a space
D = mass (g)
volume (cm3)
48 g
2cm
3cm
4cm
V= 2cm x 3cm x 4cm
V= _______
D =
19.3 g/cm3
The density of water is 1.0g/cm3

16. TIME the interval between two events
Standard unit is the __________
Common units are minutes and hours

17. Temperature
The standard unit for temperature is the Kelvin. We use Celsius and Fahrenheit in everyday life.
