WE ARE GOING TO LEARN A NEW

MEASUREMENT LANGUAGE!

ENGLISH VS. METRIC!

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!

Metric System

Mass

Liters (L)Meters (m) Grams (g)

Length Volume

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 System

Mass

Liters (L)Meters (m) Grams (g)

Length Volume

Metric Prefixes

• Kilo (k) – largest• Hecto (h)• Deca (da)• BASIC UNIT!!• Deci (d)• Centi (c)• Milli (m) – smallest

• They will never be by themselves, they have to be written with a suffix.

Length Mass Volume

Kilo + meter Kilo + gram kilo + liter

hectometer hectogram Hectoliter

Decameter Decagram Decaliter

Decimeter Decigram Deciliter

Centimeter Centigram centiliter

Millimeter Milligram milliliter

Why do we have specific prefixes for each type of measurement… Length

Km mmA big measurement A small one

Same scenario works for volume and mass• Volume – what units

(prefix + suffix) would you use to measure the volume of this?_______

• Mass - what units (prefix + suffix) would you use to measure the mass of this?_________

Which is longer?

A. 1 mile or 1 kilometer

B. 1 yard or 1 meter

C. 1 inch or 1 centimeter

1.6 kilometers

1 mile

1 yard = 0.9444 meters

1 inch = 2.54 centimeters

Metric Units

The basic unit of length in the metric system in the meter and is represented by a lowercase m.

Metric Units

1 Kilometer (km) = 1000 meters

1 Meter = 100 Centimeters (cm)

1 Meter = 1000 Millimeters (mm)

Which is larger?

A. 1 meter or 105 centimeters

B. 4 kilometers or 4400 meters

C. 12 centimeters or 102 millimeters

D. 1200 millimeters or 1 meter

Making Accurate Metric Measurements Always(MAMMA)

• You have been hired on by the esteemed company MAMMA.

• Your job is to accurately measure and weigh anything and everything in front of you!

• If you are able to complete the following tasks you will be promoted to chemist (which is a necessity to continue further in Miss Miks’ class!!)

Three parts:1. Length2. Mass3. Volume

Good luck and happy measuring!

Lesson 2: Mass

Turn to a new page!!

English vs. Metric Units

Which is larger?

1. 1 Pound or 100 Grams

2. 1 Kilogram or 1 Pound

3. 1 Ounce or 1000 Milligrams

1 pound = 453.6 grams

100 kilogram = 220 pounds

1 ounce of gold = 28,349.5 milligrams

Metric Units

Mass refers to the amount of matter in an object.

The base unit of mass in the metric system in the kilogram and is represented by kg.

Metric Units

1 Kilogram (km) = 1000 Grams (g)

1 Gram (g) = 1000 Milligrams (mg)

Which is larger?

A. 1 kilogram or 1500 grams

B. 1200 milligrams or 1 gram

C. 12 milligrams or 12 kilograms

D. 4 kilograms or 4500 grams

Kilogram Prototype Image - http://en.wikipedia.org/wiki/Kilogram

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?

_______ + ______ + _______ = ________ g70g 300g 3.35g 373.35

Let’s put out knowledge to work in the lab!

Lesson 3: Volume

Turn to a new page!!

English vs. Metric Units

Which is larger?

A. 1 liter or 1 gallon

B. 1 liter or 1 quart

C. 1 milliliter or 1 fluid ounce

1 gallon = 3.79 liters

It would take approximately 3 ¾ 1-liter bottles to equal a gallon.

1 fl oz = 29.573 ml

1 12-oz can of soda would equal

approximately 355 ml.

1 quart = 0.946 liters

Metric Units

Volume is the amount of space an object takes up.

The base unit of volume in the metric system in the liter and is represented by L or l.

Metric Units

1 liter (L) = 1000 milliliters (mL)

1 milliliter (mL) = 1 cm3 (or cc) = 1 gram*

Which is larger?

A. 1 liter or 1500 milliliters

B. 200 milliliters or 1.2 liters

C. 12 cm3 or 1.2 milliliters*

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.

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.
