1. The Metric System

2. Classe de bonjour. Aujourd'hui nous apprendrons du système métrique.

3. International System of Units
Abbreviated SI
-Système International d‘Unités
System of units of measurement
Developed from France’s metric system.

4. What is the metric system?
Based on powers of 10
Easy to convert.
Based on something logical.-the Earth

5. What is the unit for length?
A meter.
We use a ruler or meter stick to measure length.
Never use inches!

6. What is the unit for length?
Originally the meter was 1/10,000,000 the Earth’s circumference (North pole through Paris to Equator).
10,000,000 m
10,000 km 

8. What is the unit for mass?
A gram.
We use a triple beam balance or electronic balance to measure mass.

9. What is the unit for volume?
A liter.
We use a graduated cylinder to measure volume.
Volume is the amount of space something takes up.

10. BIG What is a metric prefix?
A small word at the beginning of a bigger word.
Science has and small prefixes but they are similar to compare.
BIG

11. What are the metric prefixes?
Abbreviation
What it means
Example
KILO k
x 1000
Huge
HECTO h
x 100
Big
DECA da
x 10
Large
BASE
m, l, g
Meter, liter, gram
Normal
DECI d
1/10
Small
CENTI c
1/100
Tiny
MILLI m
1/1000
Miniscule

12. Metric Prefixes (cont.)
For REALLY big and small
Tera ,000,000,000,000 (trillion)
Giga ,000,000,000 (billion)
Mega ,000,000 (million)
Micro (millionth)
Nano (billionth)
Pico (trillionth)
Notice: in science we use multiples of 3 for scientific notation

13. What is the metric staircase?
An easy way to convert from large prefixes to small or a small prefix to a large.

14. Metric Stairs Kilo (k) Hecto (h) Deca (da) BASE Deci (d) Centi (c)
Milli (m)

15. What are the steps to convert?
Mark your base.
Mark your starting prefix point & move on the steps to the desired prefix.
Move the decimal left or right depending on which way you went on the stairs and the number of stairs.

16. Metric Stairs k h da d c m gram Liter meter — g L m g L m g L m g L m

17. 100cm = ? m 100cm = 1.00m k h da - d c m Mark your base
Mark your starting & move
Move 2 steps to the left
Move decimal 2 to the left c m m m
100cm = 1.00m

18. 10 cg = ? mg 10cg = 100mg k h da - d c m Mark your base
10 cg = ? mg k g h g da g - g d g
Mark your base
Mark your starting & move
Move 1 step to the right
Move decimal 1 to the right c g m g
10cg = 100mg

19. k h da
m,L,g d c m

21. So let’s measure!
