Scientific Method
8-1.1 Design a controlled scientific investigation.
- recognize steps appropriate for conducting a controlled investigation
- construct explanations and conclusions from interpretations of data obtained during
a controlled scientific investigation
- classify by sequencing the steps of a controlled scientific investigation
- summarize the steps in a controlled scientific investigation

• Pose a
Question
• Why won’t
my cell
phone turn
on?
• Research
information
• Consult an
expert user,
review the
user’s
manual,
research
online
• Develop a
hypothesis
• I predict that
my cell
phone will
not turn on
because it is
not charged.
• Design an
• Charge cell
experiment phone and
test
whether it
turns on
• Conduct • I plugged in my
experiment charger and
connected it to my
phone.
• Next I waited a few
minutes then tried to
power on the phone.
• Record Data
• My cell
phone did
not turn on
even after
being
charged 5
minutes.
• Analyze
Data
• Fill out a
chart of
what did or
did not
work.
• My hypothesis that my cell phone
did not work because it needed
to be charged was not supported
Conclusion because it did not power on after
being plugged in to a charger.
•State
a
• This experiment could be
improved by testing the charger
at different electrical outlets.
• Further questions I now have based
on this experiment include:
–Is my cell phone not turning on
Conclusio because:
n
• the electricity powering the
charger could not be working
• the charger could be
malfunctioning
• the phone could be permanently
damaged from water, overheating, poor battery connection

HW: Scientific Method Flow Chart
• On a new separate piece of paper create a
FLOW CHART of the scientific method steps in
order.
• Include a basic explanation of each step in
your own words.
CW
• Directions: Identify the step. Then number
them in sequential order. (10 minutes)

CW: Forming Hypotheses and
Designing Experiments
• Exit Ticket: Design an experiment for the
following below. (Do not have to copy)
• Problem: My plant is drooping toward the
floor.
• Observation: My plant was tall and sturdy last
week before I left on vacation.
• Hypothesis: If I water my plant 3 times a
week, then it will be tall and sturdy.
• Experiment: (?)
