Transcript Is Your Home Well?

Home Comfort
A Model of the Scientific Method
Why are we
learning this??
Summer time spent with WellHome.

company
Doodle Sheet A
Answer these questions on your
doodle sheet.
Is your home comfortable
(temperature)? Is it too hot during
the summer and too cold during the
winter? Why do you think it is
comfortable or too hot or too cold?
Doodle Sheet B
Write 4 questions about
insulation on your doodle sheet.
Problem:
 When spraying in insulation in a roof for a
client, there was a problem. When the
insulation was installed there was room to
move around in the attic. The $2200.00
worth of insulation was removed and
replaced. How do we approach this
problem to prevent this from happening?

Driving Question:
What steps do we need to take to
solve this problem? – do not show
to students
Doodle Sheet C
What questions can we ask about
solving this problem?
OBSERVATION LAB
You will be looking at 8 different
samples. With your group
determine 6 characteristics that you
will describe the samples.
Record all your information on the
lab sheet
Record the first step in your Log
sheet:
Step 1: Using your senses to
observe interactions around the
real world.
Record this on your Log Sheet
Step 2: Ask Questions
Write this on your LOG SHEET
STEP 3:
A Hypothesis is an
explanation for a question
that can be formally tested.
a.k.a: an educated guess!
If…then…because….
In a well designed Experiment, you
need to keep all variables the same
except one.
 Independent Variable: The factor that is
changed in an experiment.
 Dependent Variable: The results of the
changes.
 Control:
same!
The factor(s) that remains the
 Controlled Experiment:
An experiment where all factors except one
are kept the same; all of these factors are
called the “controlled variables”
For Example
 Question: Which freezes faster…fresh water or salt
water?
 Hypothesis: IF I add salt to fresh water, THEN
the salt water will take longer to freeze
 Experiment:
Independent Variable: the salt that is added to the
water
Dependent Variable: the time it takes for the water
to freeze
Control: The fresh water.
Controlled Experiment: All factors, or potential
variables are kept the same, such as temperature and
amount of water

Step 4: Test Your Hypothesis
Doodle Sheet D
What are important aspects when
performing a lab experiment?
Doodle Sheet E
 When looking at data, what do we need to
do to make this information useful?
Record your answers in Doodle Sheet E.
Step 5 Record this on your LOG
Sheet
COLLECT DATA: The observations
and measurements you make in
an experiment are called Data.
Examples of data are values in pH,
temperature, measurements, color.
Record onto your LOG Sheet
Step 6: Analyze your data
Did your experiment support your
hypothesis?
Record on to LOG Sheet
Step 7: Conclusion: a summary
of the research and the results of
the experiment
Record onto LOG Sheet
Step 8: Retest
Final Assessment
 Be complete in your responses.
 Address each point on the Log Sheet
