How do questions fuel the study of science?

You are walking though a field with some
friends. Suddenly, you notice that there are
frogs hopping around all over the place! You and
your friends start catching the frogs with your
hands. As you lift the first frog from the net,
you notice something. Its legs seem to be
broken. You look at your friends frog. It
seems to be injured, too. You look at another.
A frog with no eyes? Wait a minute! These frogs
arent injured. Theyre deformed!
1995

The friends, like almost all scientists, begin
their research by noticing something about the
natural world and then by asking questions about
what they observe. Why was asking questions
important in the case of the frogs?

It All Starts with a Question!
Who? What? When? Where? Why?

• The Scientific Method
• Observation
• Question
• Collect Data
• 4.Form a Hypothesis (From Collected Information)
• 5.Test the Hypothesis
• 6. Analyze Results of Data
• 7. Draw Conclusions/Communicate Results
• Check out chart on pg. 17 in book.

5
Ask a Question

• Identify the Problem
• Decide what you
• want to know

6
Collect Data

• Observe
• Measure
• Do research

7
Form a Hypothesis
If .then... statement!
I believe that if I take light away from the
plant at my house they will NOT die!

• Designing a test
• Identifying Variables
• -Control
• - Experimental
• State the Hypothesis

8
Experiment/Test the Hypothesis

• Select a control group and experimental group
• Determine how these variables will be
  measured/controlled
• Do the experiment

9
Variables

• Independent
• The one factor that your changing in your
  experiment.

• Dependent
• Is what your measuring in your experiment.

• Constant
• All the factors that are kept the same.

10
Analyze Results of Data

• Observe
• Record
• Organize
• Gather

11
Draw Conclusions

• If wrongreform hypothesis
• If rightredo experiment to prove!

I was right! I am a genius!

Drawing ConclusionsScientific Validity

1. Hypothesis Guess
2. Theory A hypothesis that has been supported
   over a long time, but never proven.
3. Law A theory that has been tested, validated,
   and proven true.
