Problem: Always the toughest part!!

Written in the form of a question.

All research will be focused on finding an answer to the question.

The Answer to the problem should have only one answer, for example,– Yes/No– Greater/Lesser

Hypothesis

Written as an “IF……

THEN…” statement.

For example:– If plants are denied light for two months than

they will die.

If: the action of the experiment

Then: the results of the experiment

Experimentation:

The experiment must be a controlled experiment. -Control group (Compare results to)

-At least one experimental group (contains the experimental variable)

There should be at least 10 subjects in each group or it should be repeated on one subject 10 times.

DATA:Rough/Raw:– This is disorganized lists, sketches…

Smooth:– Data for each group is displayed

separately in graphs and tables

Analyzed:– Graphs and tables that compare your

experimental group with your control group

Analysis and Conclusion

These are often found together.

Conclusion:– Based on experimental results

the hypothesis is accepted/rejected.

Analysis:– Brief discussion of results and why they lead

you to accept or reject the hypothesis
