Scientific Method
1.Ask a Question
2.Form a Hypothesis
3.Conduct a Controlled Experiment
4.Collect Data
5.Analyze the Data
6.Report Conclusions
Scientific Method
Ask a Question and form a hypothesis
What are you curious about?
What do you doubt?
What do you want to know more about?
 Must explain an observed phenomenon
 Must be testable
Methods of Science
Conduct controlled experiment
Experimental Design
 Independent variable—only one factor in a
controlled experiment can change at a
time.
 Dependent variable—results from or
depends on changes to the independent
variable.
Methods of Science
Collect Data
 Empirical Data - information gained from
observations, experience or experiment
 Quantitative data can be measurements of
time, temperature, length, mass, area,
volume, density, or other factors.
 Qualitative data are descriptions of what our
senses detect.
Methods of Science
Analyze Data
 A graph of the data
makes the pattern
easier to grasp.
 Even when a
hypothesis has not
been supported, it is
valuable.
 Go beyond simple analysis
Methods of Science
Report Conclusions
 Evaluation of whether hypothesis was
confirmed or disproved
 Summary of the science
 Analysis of the results
 Elaboration of key points
 If you did the experiment again, would you
get the same results? Why or why not?
 What are the next steps/questions
