1. Metric Measurement

2. Types of Metric Measurement
Length
Mass
Volume
Temperature
Density
Time

3. Length Distance between 2 points Basic Unit: meter (m)
Equipment: meter sticks, metric rulers

5. Mass Amount of matter in an object Basic Unit: gram (g)
Equipment: Triple Beam Balance
Or Electronic Balance
** Weight is different than mass! Weight is mass x force of gravity. Mass is constant. Weight can change.

7. Volume
Amount of space something takes up.

8. Volume of liquids Basic Unit: liter (l) Equipment: graduate cylinder
*Always read a graduate cylinder at eye level.
Meniscus- curved upper surface of a column of liquid.

9. Volume of Liquids-cont.
Read the volume using all certain digits and one uncertain digit.
Certain digits determined from marks on cylinder
Uncertain digit is estimated.
Volume: ml

10. Volume: ml
Volume: ml

11. Volume of Solids Basic Unit: cm3 Equation: V = L x W x H Example:
V= 3cm x 3cm x 3cm
3 cm
3 cm
3 cm

12. Volume of Irregular Solids
You will use a graduate cylinder by water displacement.

13. Temperature Most scientists use Celsius (C°)
The measure of how hot or cold something is.
Basic Unit: Kelvin (K)
Equipment: Thermometer
Most scientists use Celsius (C°)

14. Density Closeness of particles(how spread apart they are)
Mass per unit volume of an object
Basic Unit: grams per cm cubed (g/cm3)
Equation: D = M / V

15. Time Interval between 2 events. Basic Unit: Seconds (sec)
Equipment: Clock or stopwatch

24. Scientific Notation A shorter way to write very large & small numbers.
Example:
300,000,000 m/s
(speed of light)
= 3.0 * 108
Coefficient Exponent
To write a number in scientific notation:
1. Put the decimal after the first digit and drop the zeroes
2. Count the number of places from the decimal to the end of the number.

25. Example 2: 0.000001 s Coefficient= 1.0 In 0.000001 there are 6 places.
Exponent: 6
Answer:
1.0 * s
Example 1:
123,000,000,000
Coefficient = 1.23
In 123,000,000,000 there are 11 places.
Exponent = 11
Answer :
1.23 * 1011

26. Scientific Notation Practice Problem 1: 1,000 000 km = 1.0 * 106 km
5, 600, 000, 000, 000, 000, 000, 000 m/s
= 5.6 *1021 m/s
Practice Problem 3: L
= 3.11 * 1014 L
