If a paper is folded in half, then it can only be folded ________ times because it will become too thick to fold.
Independent - folding the paper Dependent - how many times it actually is folded
We conclude that our hypothesis was supported or not supported based on our data.
1. The Scientific Method
2. The Awareness Test
3. What is the Scientific Method?
• An organized plan for gathering,
organizing and communicating data
• The basic steps that scientists follow in
uncovering facts and solving scientific
problems ( a plan for solving a problem).
• Six or Seven Steps - depends on source
4. What is the Scientific Method?
• Make an Observation
• Ask a Question
• Complete Background Research
• Develop a Hypothesis
• Test your Hypothesis
• Analyze the Data
• Conclusion (Report and Share)
5. Step 1: Observation
• Everything starts with an observation
• What you perceive with your senses
What can you
observe about a
piece of paper?
6. Step 2: Forming a Question
• Based on your observations
• Develop a question or problem that can
be solved through experimentation.
Can you form a
• Usually a “How’ or “Why” question
7. Step 2: Forming a Question
How many times
can you fold a
piece of paper?
8. Step 3: Complete Background
• Collect knowledge needed to know
about the subject of the experiment
• It will be used to form a
9. Step 4: Develop a Hypothesis
• Hypothesis = an educated prediction to
the answer of the stated problem
• Based on research and prior knowledge
Not a W.U.G. !
10. Step 4: Develop a Hypothesis
• A proposed answer to your question
• There is no right or wrong hypothesis
11. Format of Hypothesis
• Two accepted formats:
• Both formats include the all important
“because statement” used to justify your
12. Step 4: Testing Your Hypothesis
• This is where you conduct an experiment (a
situation specially set up to observe how
something happens or to test your
• Develop a set of repeatable methods
• The goal is to test your hypothesis by collecting
13. Step 4: Testing Your Hypothesis
• Includes variables - a quantity that is
measured or changed during the
What you are changing in the experiment
The outcome caused by changing the
independent variable, a measurement
Control Used for comparison in your experiment
Constant What stays the same from one experiment
to the next
14. Step 4: Testing Your Hypothesis
What are our variables in the paper folding experiment?
independent variable cause
dependent variable effect
15. Step 5: Collect and Analyze the
• Interpret the data you
gathered from your
• Observations, information and data are collected
from the experiment
• Organize the data and perform calculations
16. Step 5: Collect and Analyze the
• Construct charts, graphs, averages,
on the Y-axis
on the X-axis
How would you
17. Step 6: Conclusion
• Does your data support your
You just made a
Revise or make a
new hypothesis and
18. Step 6: Conclusion (Sharing)
• A summary of results,
the answer to your
• What were the possible
sources of error?
• Does your data (answer)
support your hypothesis?
Why or why not?
What conclusion can you make about paper folding?
19. What about a huge sheet of paper?
20. Why use the Scientific Method?
• A logical way to problem solve - in all
aspects of life.
• A way to share information that can be
proved or disproved.
• A way to find new information
