Ms. Z wants to purchase new pens for School of the
Future. She needs to know which type of pens lasts the
longest. She asks the teachers if there is a type that
they like the best. Ms. Baum loves ball-point pens, Ms.
Glatzer prefers gel pens, and Mr. Lynch likes felt-tip
pens. Ms. Baum thinks if she buys gel pens, then they
will last the longest. She purchases the three types,
and she gives each type to a group of 20 students to
use and see how long they last. She writes down how
many words each pen can write before it dies. The
group with ball-point pens can write an average of
10,000 words before the pen dies; the gel pens write
5,000 words; and the felt-tip pens last for 11,000
words. LWBAT identify the stages of this scientific
method.
Step 1: State problem/ask question
Ms. Baum wants to know which pens last the longest
Step 2: Gather info
Ms. Baum asks the other teachers which pens they like
Step 3: Form hypothesis
Ms. Baum says, “If I use gel pens, then they will last the
longest.”
Step 4: Perform experiment
She purchases the 3 types of pens, gives them to
students, and records the average number of words they
can write
Step 5: Analyze data
Ball-point=10,000 words, gel pens=5,000 words, felttip=11,000 words
Step 6: Draw conclusion
Ms. Z determines that the felt tip pens last the longest and
her hypothesis is NOT supported. She rejects it.

A Scientific Method Review
Your science teacher gives groups of students 4
sets of cards/tiles. He wants to check if his
students can demonstrate developing knowledge
of the objectives he has taught so far by
demonstrating their knowledge and ability in a
group setting & to communicate results of
investigations using multiple representations.
Take a moment to look over the cards/tiles and
determine in your group a procedure that you
would use to apply to this activity. After writing
the procedure in your science notebook, do it.

3. A group of students conducted an experiment to measure the temperature of a chemical
reaction. They mixed two chemicals in a beaker and used a thermometer to measure the
temperature during the reaction. When they submitted their work, the teacher said that the
temperature they recorded was not accurate. What should the students have done to make their
data more accurate?
A. They should have conducted multiple trials to verify their first result.
B. They should have used two thermometers to measure the temperature.
C. They should have asked other groups what temperatures they recorded.
D. They should have added more of each chemical to make the reaction go faster.

The study of biology requires an understanding of many technical terms. Sometimes you
can find the meaning of an unfamiliar term by looking at its parts. In this activity you will
analyze such parts to help you understand many of the terms you will encounter in
biology. Many words have prefixes and suffixes that provide clues to their meanings. The
following table contains a list of prefixes and suffixes that are often part of biological
terms. Look at the table and study it carefully.
Use the prefixes and suffixes to form 5 biology terms.
Example Chloro - green and phyll – leaf = green leaf (substance

Distinguish between the
scientific terms: inference,
hypothesis, fact, law,
observation, principle and
theory.
Distinguish between the scientific terms: inference,
hypothesis, fact, law, observation, principle and theory.
An inference is like saying: All A's = B. and all
B's = C. Therefore all A's = C.
A hypothesis is just an idea that is testable
and can be supported or rejected by
experimental evidence.
A fact is a hypothesis that has been so
thoroughly tested and accepted that it is
assumed to be true.
A scientific law is a statement that shows
relationship between things. Ex: Gravity
An observation consists of receiving knowledge
of the outside world through our senses, or
recording information using scientific tools and
instruments. Any data recorded during an
experiment can be called an observation.
A scientific principle is a statement that explain
the 'why' and 'how' of various phenomena.
A theory is constructed from observational data
to explain that data, and to be able to predict
future outcomes.
