1. Get an idea
for your project
Find an area that interests you. You might want to look at a list of science
fair categories to help decide. Talk over ideas with your family, teacher or
friends. Use TV commercials, magazines, newspapers, or books to get more ideas.
Think about problems around the house that you would like to solve. You can
even test household items.
2. Start a Daily
Log
Use a separate notebook or booklet as your Daily Log and divide it into two
sections: "Daily Work" and "Data."
3. Do a search
for background information
Every scientist spends time getting background information. Use the library;
write or call experts; write to companies and organizations; use the internet
on your computer. Start keeping a bibliography with complete information on
every source you used and tried to get. Good research will help you become an
expert on your topic. As an expert, you will be able to make a better
hypothesis, plan better testing, and draw better conclusions. You'll also
impress others with your knowledge when you share the results of your project
with them.
4. State the
problem in a question form
This part (often used as a title) asks what you are trying to find or show in
your investigation. Make sure your problem is one that can be solved by
testing. It must involve more than a demonstration or a collection.
5. State your
hypothesis
The hypothesis is an educated guess or a prediction of what you think will
happen during your experimentation. Use background information to help you
prepare this prediction and to explain it. The results of the test you do later
do not have to support the hypothesis in order for the experiment to be a
success.
6. Design the experiment
Determine the procedure that you will follow to test your hypothesis and record
it in your Daily Log. The procedure should explain the steps to be followed in
order to find the answer to your question or problem. Think about necessary
safety precautions that will be taken. Make a complete list in your Daily Log
of all the materials you will need.
A good procedure is very detailed - like a good recipe. This
makes it easy for other scientists to duplicate your experiment so they can
verify your results.
7. Conduct the experiment
Follow your procedure carefully to ensure fair, scientific testing. While
testing, record in your Daily Log all data by accurately observing, measuring,
describing, couting or photographing. Work safely. If
necessary, make changes in your procedure and document them in your Daily Log.
8. Repeat the procedure
The results will be more convincing and valid if you repeat the experiment as
many times as possible. For example, an experiment that uses ten plants will
give more valid results than one that tested only one or two plants. Testing
and measuring the distance a car rolled down a ramp ten times would be more
valid than testing it only one time.
9. Analyze the data (Results)
Look at the measurements you recorded in your Daily Log closely. Decide what
the results mean. Try to find explanations for your observations. If possible,
examine your results mathematically (percentages, mean, median, range, mode).
Construct graphs or tables that will go on your backboard to show the results
more clearly. The data will help you decide whether your hypothesis is
supported or should be rejected.
10. Make conclusions
Conclusions are statements telling what you found out or learned during your
investigation. This is a very important part of your project since you probably
learned a lot. They are based on the results of your experiment and your
hypothesis. Explain how the data you collected supports your hypothesis. If the
data doesn't support your hypothesis, explain why you reject your hypothesis.
Explain what further testing might be done to better answer your original
question. Tell how people might apply your findings to every day life. Can you
explain any unusual findings from your testing?
11. Communicate your results in a summary
Scientists share their findings with other scientists. Write a short (one page)
five-paragraph summary that explains the most important parts of your project.
An easy format to use is to write one paragraph that summarizes each of the
following:
Practice an oral presentation also. Be an expert on all
parts of your project so you'll be prepared to answer an interviewer's or
classmate's questions.
12. Construct a display that explains your
project
Dimensions - Exhibits will be confined to a table space and must not
exceed 2 feet from side to side, 3 feet high, and 15 inches from front to back.
Exhibits should be durably constructed and self supported.
Science Folders - all students must display two folders in
front of the backboard. The first, the science folder, should include the Daily
Log, summary, and list of materials. The following items may also be included
in the science folder: research, letters written to obtain information,
newspaper articles related to the topic, surveys, graphs, charts, pictures, and
definitions of vocabulary words. The second folder should include a report with
the bibliography.
Required Parts of the Project and Display
Question/ |
What the
students wants to find out, written in question form. The question must be
one that can be answered by doing an experiment or investigation. |
Hypothesis |
A
statement predicting what might happen as a result of doing the investigation
or experiment |
Procedure |
Steps the
student followed to complete the project. |
Results |
Explanation
of what the data means...graphs, charts, hypothesis. |
Conclusion |
An answer
to the original question that relates to the hypothesis. |
Materials |
A list of
materials used to complete the experiment or investigation. The list of
materials may be put on the display board or in the science folder. |

explanation, etc. |
Daily log |
A journal
recording of the steps and procedures of the experiment or investigation. |
Summary |
A written
explanation of the project. Include the title of the project, why the topic
was chosen, the results (what happened), how the results compared to the
hypothesis, and what was learned. |

13. Be ready to answer questions that judges
often ask
Below is a sample of questions that judges often ask students during judging
interviews. It is a good idea to practice answering the following questions
before meeting the judges:
