1. Intro to the Metric System
FORGET ABOUT THE UNITS OF MEASUREMENT THAT YOU ARE USED TO!!!

2. Agenda Quiz Drill Conversions and the Metric System Practice Exit Slip
HW: Optional

3. How many minutes are there in a day?
Drill
How many minutes are there in a day?

4. How do I convert in chemistry?
Essential Question
How do I convert in chemistry?

5. Remember: Units have to cancel diagonally
The top and bottom in a square are equivalent
You must end in the units that you want
MAKE SURE TO WRITE YOUR UNITS IN EVERY SQUARE AND IN YOUR ANSWER!!!!!!!! 

6. A cheetah has been clocked at 71 miles per hour
A cheetah has been clocked at 71 miles per hour. How fast is this in centimeters per minute?
1 mi = 5280ft in = 2.54cm

7. There are only 2 things you need to know to use the metric system:
Metric = Simple
There are only 2 things you need to know to use the metric system:
A set of prefixes
Base units of measurement for distance, weight, volume, and temperature.

8. Distance “Meters” are the standard unit of measurement for distance.
Michael Jordan is
about 2 meters tall….
and can jump over
1 meter in the air!
The average male in the U.S. is 1.77 Meters Tall
The average female in the U.S. is 1.64 Meters Tall

9. “Grams” are the standard unit of measurement for weight.
A new-born baby usually weighs
between 2, grams.

10. A 2-Liter soda bottle is our most common use “liters.”
Volume
“Liters” are the standard metric unit for volume (remember the formula for volume?)
A 2-Liter soda bottle is our most common use “liters.”

11. There are a few basic prefixes that will help us greatly:
Kilo = or 1 x 103
Hecto = 100 or 1 x 102
Deca = 10 or 1 x 101
Deci = 1/10 or 1 x 10-1
Centi = 1/100 or 1 x 10-2
Milli = 1/1000 or 1 x 10-3

12. More Prefixes… Mega = 1,000,000 or 1 x 106
Giga = 1,000,000,000 or 1 x 109
Micro = 1/1,000,000 or 1 x 10-6
Nano = 1/1,000,000,000 or 1 x 10-9
Where have you heard “nano” before?

13. Why prefixes? Weight: Kilograms, grams, milligrams Distance:
Standard metric units (grams, meters, liters) are not always the most convenient.
In chemistry, we will frequently use the following units of measurement:
Weight:
Kilograms, grams, milligrams
Distance:
Kilometers, meters, centimeters, millimeters, nanometers
Volume:
Liters, milliliters

14. Other convenient conversions
1 cm3 = 1mL
1 m3 = 1000L

15. HW
If you are unsure of how to convert to scientific notation (or want a refresher), you need to watch the video and complete the note sheet
If you do know how to convert, you DO NOT need to watch the video
