Scientific Method Review
You have now worked on two labs—
paper airplanes and cabbage juice pH.
What are the five steps of the
Scientific Method.
What is important to remember
about each?

Turn to your shoulder partner
and discuss the characteristics of
an acid.
Then list at least three acids.
After coming to an agreement,
write your answers on your warmups.
Characteristics:
Examples:

Characteristics:
Dissolves Metals
Tastes Sour
pH less than 7
Examples:
Lemon Juice
Apple Juice
Vinegar

•Turn to your shoulder
partner and discuss the
characteristics of a base.
•Then list at least three bases.
•Next figure out the
other name for a
base.
After coming to an
agreement, write
your answers on
your warm-ups.
Tuesday, September 13, 2011
Characteristics:
•Slippery
•Bitter taste
•pH greater than 7.0
Examples:
•Baking Soda
•Detergent
•Oven Cleaner
Base = Alkaline

If a liquid has a pH of 7.0, it is said to be:
A. A base
B. An acid
C. Neutral
D. Alkaline
Tuesday, September 13, 2011
If a liquid has a pH of 7.0, it is said to be:
C. Neutral
Water and fresh milk
are neutral liquids, thus
have a pH of 7.0.

Use each of the pH vocabulary words in a
sentence.
acid
base
pH scale
alkaline
neutral
Example:
Lemon juice is an acid
because it has a pH of less than 7.
Remember
Base = Alkaline
Wednesday, September 14, 2011
Use each of the pH vocabulary words in a
sentence.
acid
base
pH scale
alkaline
neutral
Examples:
Lemon juice is an acid because it has a pH of less than 7.
An alkaline and an acid of equal strength would neutralize each other.
Ammonia is a strong base and feels slippery.
Distilled water is neutral with a pH of exactly 7.
The pH scale is helpful in telling how acidic or alkaline a substance is.
Remember
Base = Alkaline

Why would a scientist test the
pH of a river?
Use the following words in your answer:
Base, acid, pH, and organism

Multiple Meanings: Concentration
Concentration (noun)
Concentration (noun)
1) The focus a person gives to a task.
2) The amount of a substance (liquid, powder, solid) in
a given volume.
Example: The boy showed great
concentration during the chess game.
Use the word concentration in your
answer to this question:
What is an activity that you must
have a great deal of concentration to
do?
Example: After the oil spill, the concentration of oil
in the Gulf was so high that it killed fish.
Use the word concentration in your answer to
this question:
What do energy drinks have a high
concentration of?
