data and results
A summary of the data you have collected (graphs, tables, charts, photos, etc.); all your observations from the experiment
conclusion
the answer to your question; a summary of what you have learned from an experiment
Example of a problem
How does the amount of water in a bottle affect the sound made when the bottle is tapped?
Example of a Hypothesis
If the amount of water is more, then the sound will be lower when the bottle is tapped.
Variables
Change one thing when you test your hypothesis. Keep everything else the same.
Experiments
Test your hypothesis. You may need to do this step more than once to see if the results are the same each time.
scientific method
a series of steps that scientists use to answer questions and solve problems
Problem/Question
always in form of a question; the question we are trying to answer by doing the experiment
hypothesis
An educated guess
control group
part of an experiment that does not contain a variable; all conditions are kept normal; used as a COMPARISON
independent/manipulated variable
factor in an experiment that a scientist purposely changes; the cause
dependent/responding variable
the factor that changes (measured) as a result of the experiment; the effect
Data
Organize into charts, tables, drawings, and diagrams. You can decide what the information means.
Conclusion
Compare your results and hypothesis. Decide if your hypothesis is right or wrong. Tell what you decide.
