TOPIC: Measurement
Aim: Explain can we convert measurements?
Do Now:
Identify the units used to measure the following:
HW: Ditto – Density (on back of your density notes).
Measurement UnitsLength
Mass
Volume of a regular solidVolume of a liquid
Density of a solid
Density of a liquid
Announcements:
1.Measurement test is rescheduled for Tuesday, October 18th.
2.Your Scientific Method test will be returned tomorrow to go over it. You will have a Scientific Method Quiz this Tuesday, October 11th.
3.We will discuss how to do your bibliography for your research on Friday. That will be due on Wednesday, October 12th.
A cube is 1 cm on each side and has a mass of 2 grams. Will it float?
a. yes
b. no
c. The only way to tell is to put it in water.

• Comes BEFORE the unit
PREFIX
•Kilo = x 1000–1 kilometer (km) =–1 kilogram (kg) =–1 kiloliter (kl) =
1000 meters
1000 grams
1000 liters
•Centi = 0.01–1 centimeter =
–1 centigram = 0.01 meter
0.01 gram
•Milli= 0.001–1 millimeter =
–1 milligram = 0.001 meter
0.001 gram

Base (m, L, g)
DECI (d) CENTI
(c) MILLI (m)
EXAMPLES1. 100 mm = ? cm
100 mm = 10cm
Move 1 to the left
2. 34 km = ? m
Move 3 to the right
34 km = 34,000 m
3. 257 cm = ? hm
Move 4 to the left
257 cm = 0.0257 hm

Let’s summarize…
1. What do the each of the following prefixes stand for?
a) Kilo
b) Centi
c) Milli
2. What is the order of units on the conversion table?
3. How will you know which way to move the decimal?
4. How will you know how many places to move the decimal?
