What is the Scientific Method?

Review!

Problem or a question.

Something is needed to guide your

efforts.

The next step is the research.

Learn what other scientists have

done.

The next step is the hypothesis.

Proposed answer or solution to question or problem.

Design and do an experiment to

test the hypothesis.

Identify the variable.

Identify the independent and

dependent variables.

Analyze your results.

What do they mean?

Draw a conclusion.

If hypothesis is correct, report

results.

What if hypothesis is partially correct or

wrong?

Report results.My hypothesis is

incorrect because …

Review what was wrong, revaluate

hypothesis or experiment.

Change hypothesis or experiment.

If your hypothesis is correct, you have proved it,

right?

Science does not prove, it explains.

Is this the ONLY Scientific Method?

Was it written on the other side of Moses’

tablets?

No!

There is no one Scientific Method.

The traditional Scientific

Method has problems!

It ignores the

importance of

observation.

Not all changes are based on evidence.

For example, better math can

make more sense.

Scientists explore without

hypotheses.Science does not prove, it

explains.

Sometimes you can’t find an

answer.Science can be creative and

not follow steps.

One last observation.Hypotheses

Become Theories Which Become Laws,

Right?

Wrong!Let’s look at

what each term means.

A Law just explains what happens.

It does not tell us why it happens.

A theory is a well tested

explanation for some natural phenomenon.

A hypothesis is An idea or

question that can be tested.

Why do we use the Scientific Method?

It is a good general

explanation for how scientists

work.

That’s why we use it.Just remember,

there’s no such thing as a “Scientific Method.
