map (example: distance from
your house to school)
2. What units would you use to
measure each of the above
items?

How do YOU measure things?
What UNITS do you use to measure?
The International System
• Abbreviated “SI” from
the French phrase: Le
Système international
d'unités
• It is the world's most
widely used system of
measurement.
• AKA the Metric System!
Prefix vs. Suffix
• The suffix is the root word
• It always comes after the prefix.
• Example: multivitamin – “multi” is the
prefix and “vitamin” is the suffix
• Prefixes by themselves don’t mean
anything.
– Example, the prefix “Un” means nothing…..
Added to unhappy means not happy.
These are the Suffixes….

Metric Units
The basic unit of length in the metric system is the
meter and is represented by a lowercase m.
Metric Units
1 Meter = 100 Centimeters (cm)
1 Meter = 1000 Millimeters (mm)

Lesson 2:
Mass
English vs. Metric Units
Which is larger?
1. 1 Pound or 100 Grams
1 pound = 453.6 grams
2. 1 Kilogram or 1 Pound
3. 1 Ounce or 1000 Milligrams
1 ounce of gold =
28,349.5 milligrams
1 kilogram =
2.2 pounds
Metric Units
Mass refers to the amount of matter in an object.
The base unit of mass in the metric system is the gram
and is represented by g.
Metric Units
1 Kilogram (kg) = 1000 Grams (g)
1 Gram (g) = 1000 Milligrams (mg)
BELLWORK 8/25/15
1. What is the length of the blue line in
millimeters?
35 mm
2. What is the length of the blue line in meters?
0.035
3. What is the length of the blue line in
centimeters?
3.5cm
4. What is the width of your desk in centimeters?
60cm

Measuring Mass
We will be using triple-beam balances
to find the mass of various objects.
The objects are placed on the scale and
then you move the weights on the beams
until you get the lines on the right-side of
the scale to match up.
Once you have balanced the scale, you add up
the amounts on each beam to find the total mass.
What would be the mass of the object measured
in the picture?
70g
300g + _______
373.35 g
3.35g = ________
_______
+ ______
BELLWORK 8/27/15

1.What is the name of the scientific
instrument you use to measure
mass?
You use a Triple Bean Balance to take mass of an
object.
2. What is the first thing you do when
you are taking the mass of an object?
Make sure the TBB is balanced before you take
the mass of an object.
Lesson 3:
Volume
English vs. Metric Units
Which is larger?
1 fl oz = 29.573 ml
A. 1 liter or 1 gallon
1 12-oz can of soda
would equal
approximately 355 ml.
B. 1 liter or 1 quart
C. 1 milliliter or 1 fluid ounce
1 quart = 0.946 liters
1 gallon = 3.79 liters
It would take approximately 3 ¾
1-liter bottles to equal a gallon.
Metric Units
Volume is the amount of space an
object takes up.
The base unit of volume in the
metric system is the liter and is
represented by L.
Metric Units
1 liter (L) = 1000 milliliters (mL)
Measuring Volume
We will be using graduated cylinders to
find the volume of liquids and other objects.
Read the measurement based on the bottom of the
meniscus or curve. When using a real cylinder, make
sure you are eye-level with the level of the water.
43
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid
attract those of the container. The glass attracts the water on
the sides.
Measuring Liquid Volume
What is the volume of water in each cylinder?
37mL
52mL
23mL
Pay attention to the scales for each cylinder.
Practice
A. 67 mL
B. 32 mL
C. 84.5 mL
D. 45 mL
E. 2.4 mL
