3. Everyday Requirements
You must bring a notebook with you everyday
You must bring a pen/pencil with you everyday
Don’t bring your text unless I tell you

4. Keys for Chemistry Success
Read the text when it’s assigned……then read some more
Take notes during lecture and content review
Read
Ask questions, especially about the labs and exams
Complete all assignments
Get to a good start by turning in everything and staying organized

5. Behavior during Labs Be careful
If you break something, immediately report it to Mr. Button
If it was an accident, no fee
This isn’t free time – it’s time to accomplish tasks
All students must participate

6. The Metric System in Chemistry
Things we will be measuring during the first lab:
Length
Time
Volume
Mass
Density
Temperature

7. Length Not often used in chemistry but useful to practice
A measurement of the distance between 2 points
Standard unit of measure is the meter (m)
Other useful units are the millimeter, centimeter and the kilometer
Milli = 1/1000
Centi = 1/100
Kilo = 1000

8. Time
A measurement of the interval between 2 separate events (tough to define)
The standard unit of measure is the second
Other useful units are milliseconds and minutes.

9. Unit Conversion
These types of calculations are done frequently in Chemistry
Going from meters to millimeters
Going from days to seconds
Example

10. Mass A measurement of the amount of matter in an object
The standard unit of mass is the gram.
Other useful units are the milligram and the kilogram
A balance is used to measure mass

11. Volume A measurement of the amount of space an object occupies.
The standard unit of volume is the liter.
Another useful unit is the milliliter.
There are different ways to measure volume. You can measure it using length measurements or by using devices like a graduated cylinder

12. Volume Important ideas
A milliliter is the same thing as a cubic centimeter. In other words, if an object has a volume of 12 cubic centimeters it also has a volume of 12 milliliters.
1 milliliter of water has a mass of 1.0 gram (at 4.0o Celsius)

13. Density A measurement of an object’s mass as it relates to its volume.
In other words, a liter of gold is much heavier than a liter of water because gold has a greater density than that of water.
The standard unit is grams/milliliters or grams/cubic centimeters.

14. Density The density of water is 1.0 grams/mL or 1.0 grams/cm3
If an object’s density is greater than 1, it will sink in water
If an object’s density is less than 1, it will float on water

15. Temperature A measurement of the amount of heat energy in an object.
The standard unit is degrees Celsius
Water freezes at 0oC.
Water boils at 100oC.
