What is the Scientific Method? A step by step procedure that
is used to determine if a testable hypothesis is valid.
General Steps:
1) Problem/Question ( based on observations around us)
2) Research/Background Information
3) Formulate a Testable Hypothesis
4) Experimentation ( state control, variables: independent
and dependent)
5) Collect Data ( quantitative; qualitative)- tables
6) Chart and Communicate Results ( line, bar, or circle
graphs)
7) Form a valid conclusion
Group Activity One and Two
Instructions
Activity One: On the construction paper, create two columns.
Label one column : Hypothesis
Label the second column: Not Hypothesis
Discuss with your desk-mates whether each statement on each card is a hypothesis or
not. Glue each card into its appropriate column. Sit this to the side and let it dry.
Activity Two:
Create/copy the following chart off the front board onto a lose leaf sheet of paper.
Using the station cards at the lab tables ( six total), read the instructions for each card
then fill in the data table in which you have created. Turn in your Activity one
poster and your individual data tables together as a group.
Lab Safety Video
• Take notes over the safety symbols while
reviewing the short video. Your first quiz * will
have questions pertaining to lab safety. Please
listen carefully and ask questions if needed.

Examples Of an If/Then Hypothesis
Statement
If the Vitruvian Man theory is accurate, then my arm span should
equal my height.
If my arm span is equal to my height, then the Vitruvius theory is
correct.
If my arm span is not equal to the length of my height, then the
Vitruvius theory is inaccurate.
If the Vitruvius theory is accurate, then by forearm should be the same
size as my foot.
If my forearm and foot are of equal sizes in length, then the Vitruvius
theory must be correct.

Instructions/ Agenda:
September 5-6, 2012
With your desk mates, complete the lab equipment functions
worksheet. We will review this, for you will be both quizzed and
tested over this information. After this, you will view the Do’s and
Do Not’s of a Science Laboratory. Pay close attention and take notes
if needed. Remember, your Unit One quiz is next Tuesday!
Agenda:
1. Lab Equipment Worksheet- with your desk mates ( 10 min)
2. Notes: Scientific Method Continued ( 15 min)
3. Lab Safety Video ( 25 min) ( student grade conferences)
4. Closure: Course Reminders ( 5 min)
*** times may vary according to students pacing*****

Scientific Method Notes
•
Scientific method—a systematic and orderly approach to solving a problem
•
Steps of the scientific method:
•
•
•
•
•
•
1) State the problem or pose a question
2) Form a hypothesis (an educated guess)
3) Experiment
4) Collect and interpret data
5) Draw a conclusion
6) Communicate the findings
•
The conclusion should support or reject the hypothesis
Notes, Continued
• Variable—part of the experiment that changes
• Controls—parts of the experiment that stay the same; this set up of the
experiment will not be tested on
• Independent variable—the factor that a scientist changes during an
experiment; also called the manipulated variable; This goes on the X axis
• Dependent variable—the factor that changes as a result of changes to the
independent variable; also called the responding variable; This goes on
the Y axis
•
Constant: factors or conditions in an experiment that are kept the same in
in all of the trials of the experiment. ( also called the controlled variable)
More Notes….
Three Types of Science Investigations
Descriptive Investigation:
Involve describing and/or quantifying parts of a natural system. Example – observing
cells under a microscope and diagramming what is seen.
• Has a research question, procedures, and conclusion
• Used when little is known about the topic
• No hypothesis or prediction
• Key words: Observe, describe, list, identify
Comparative Investigation:
Involve collecting data on collecting data on different populations/organisms, under
different conditions (ex. Times of year, locations), to make a comparison.
• Has a research question, possible hypothesis, procedures, and conclusion.
• Can have independent/manipulated and dependent/response variables
• No control / control group
• Key words: Compare/contrast, similarity/difference, categorize
Some more notes….
Experimental Investigation:
Involve a process in which a “fair test” is designed in which variables are
actively manipulated, controlled, and measured in an effort to gather
evidence to support or refute a causal relationship. Example- Testing the
height of a ramp to determine how far a marble will roll.
• All known variables have been identified
• Has a research question, hypothesis, procedures, control, and conclusion
• Has independent/manipulated and dependent/response variables
• All factors can be held constant except the manipulated
YEAH….no more notes for the day…now pay close attention to the lab safety
video you are about to view…and take notes ( if needed) over these safety
rules…you also have the lab safety rules from your contract

1. What is matter? How can it be defined?
1. What are the three common states of
matter?
Notes ( chemistry) 9/10/12
Matter- anything that has mass and takes up space (
volume). The three most common forms of matter are
solids, liquids, and gases.
Properties of Matter
Chemical Properties- These are the properties that do
change the chemical nature/composition of matter.
Physical Properties-Properties that do not change the
chemical nature/composition of matter. The identity of
the matter stays the same; descriptions of matter.
Notes ( chemistry)-09/10/12
Examples of physical properties are: color, smell, freezing point,
boiling point, melting point, infra-red spectrum, attraction
(paramagnetic) or repulsion (diamagnetic) to magnets, opacity,
viscosity and density. There are many more examples. Note that
measuring each of these properties will not alter the basic nature
of the substance.
Examples of chemical properties are: heat of combustion,
reactivity with water, PH, and electromotive force.
