Science fair Project writing format:

The key to your success is to take science fair in small steps. To ensure this success follow the examples listed below. With some planning and creativity you will create a successful science fair project.


1. Question and “Writing the Purpose Statement"


The Purpose Statement should explain what it is you are trying to discover or prove. The Purpose should be written in a form of a statement. Try to make your statement original and creative.


The statement should clearly explain:


1.      The problem that you are trying to solve with your experiment.


2.    Why you want to do this experiment.


3.    How you think the information gained from the experiment will help other people.


Example of a Purpose Statement:

The purpose of this experiment was to find out how the density of plant cover affects soil erosion. I became interested in this experiment when the hillside next to our yard began to erode. The information from this experiment will help people to determine how many plants they should plant on their yards hillside.

2. Research: (Do your research on the topic to find out what work has been done so far.

Include 5 sources with written information about your topic) 

3. “Writing the Hypothesis"


The Hypothesis is an educated guess that tries to answer a question or solve a problem that you are trying to find out more about. The hypothesis is done after you do your research on a specific topic and before you do any experimenting.


The Hypothesis should follow these rules:


1.      A hypothesis is an educated guess about how things work.


2.    Your hypothesis should be something that you can actually test, what's called a testable hypothesis. In other words, you need to be able to measure both "what you do" and "what will happen."


   3.    "If____(I do this/ independent variable)___,then___(outcome/ dependent variable)______will
 because___________________________________________________________________. "

Example of a Hypothesis:

If I plant grass on the hillside thensoil it will do a better job at preventing soil erosion than shrubs. I base my hypothesis on the idea that there are more roots in the grass than the shrubs hence grass roots will hold onto the soil firmly.
Independent Variable:     _________________________________
Dependent Variable:        _________________________________
Control Variables:            _________________________________
Control Group:                 _________________________________ 
Experimental/test groups_________________________________ 



 4. “Writing the Materials List"


The materials list is a complete list of all materials including details and amounts. Be sure to include quantities (how much), length, volume, and mass. List these in metric units. Be specific in your description of the item needed. Include photos, or drawings of the materials if it helps the person to identify the material needed in the project.


The Material List should follow these rules:


1.      Be specific to amount, size and length.

2.    Listed in metric units where appropriate.


Example of a Material List:


Bad Material List:

Good Material List:

1.      Water

2.    Watch

3.    Ruler

4.    Dirt

1.      20 Liters of Water

2.    Stop watch with second hand

3.    Metric Ruler with millimeters listed

4.    3 cubic meters of potting soil

Description of Item:











5. “Procedure / Methods"



The Procedures should follow these rules:

1.      Label each step with a number or letter.

2.    Write your procedures in a cookbook format

3.    Be very specific with quantities, amounts and the order that things need to be done or completed.


Example of a Procedures / Method list:

1.      Prepare three trays by putting an equal amount of potting soil in each tray. If you are using pans or cookie sheets, spread a layer of gravel on the bottom of the pan before adding the soil. This will allow for drainage since you will be watering all three pans while the grass is growing.

2.    Set Tray 1 aside. In Tray 2, cover the soil with a layer of leaves and grass clippings. In Tray 3, sprinkle grass seed on the top of the soil.

3.    Place the three trays in a place where they are level and have similar light and temperature conditions. (The temperature must be above 50°F (10°C) for the grass to grow.)

4.    Use the sprinkling can to give each tray the same amount of water. Continue watering all three trays approximately every 3 days until the grass in Tray 3 is about .5 inches (1.25 centimeters) tall. This may take one week or longer. You may have to adjust your watering schedule depending on how fast the soil dries. Check the soil daily to see if it looks and feels moist.

6. “Writing the Results"



Writing the Results will include both text and illustrative material from the tables and charts. Use the text to explain and guide the reader through your key results, i.e., the information that answers the hypothesis you investigated. Use the tables and charts to help strengthen and explain what you are stating in your text.


Your results should follow these guidelines:


1.      Include what you wanted to accomplish and prove during your experiment.

2.    Describe and report what you discovered. Be sure to include any data that might have been collected. It is important to show this data even if it did not support your hypothesis. The process of completing the experiment with true data is what is important.

3.    The function of the Results section is to objectively present your key results, without interpretation.


Example of how to write the results:


The original purpose of this experiment was to see how a seeds germination is effected by the time of exposure to running water. The results of the experiment were that the duration of exposure to running water had a great effect on overall seed germination. (See Data Table 1). The seeds exposed to the 48-hour treatment had the highest percentage rate of germination (See Data Table 2). This was 2 times that of the 12-h group and 5 times that of our control group that was not exposed to the running water treatment.

Pointers for your Tables / Graphs:

v   Big or little? A good rule of thumb is to size your figures to fill about one-half of a page. The viewer should not have to get a magnifying glass to make out the details.

v   Color or no color? Most often black and white is preferred. The idea is that if you need to photocopy or fax your paper, any information conveyed by colors will be lost to the reader. However, for a poster presentation or a talk with projected images, color can be helpful in distinguishing different data sets. Every aspect of your Figure should convey information; never use color simply because it is pretty.

v    Title or no title? When you are making a  posters or projected images, where people may have a harder time reading the small print of a legend, a larger font title is very helpful.


7.“Writing the Conclusion"


What is a conclusion? A conclusion is a reexamination of your original hypothesis in regards to the data you have collected. Your conclusion will continue by describing how your results prove or disprove your hypothesis. Your conclusion included what questions you have developed in doing the experiment. It also includes how you might change your experiment if you were to continue this topic in order to explore those questions that you developed during the experiment.


Example of a conclusion:


My hypothesis was that grass would do a better job at preventing soil erosion on the hillside than shrubs. I base my hypothesis on the idea that there are more roots in the grass than the shrubs. The results indicate that this hypothesis should be considered false. The dense amount of shrub cover shielded the underlying dirt better than the grass. Because of the results of this experiment, I wonder if different kinds of shrubs have the same effect on preventing erosion. If I were to conduct this science fair project again I would try both deciduous as well as coniferous shrubs.


Fill in the following lines to create a successful Conclusion:


My hypothesis was ______________________________________



The Results indicate that this hypothesis should be considered




Because of the results of this experiment _____________________

“Writing the Bibliography"



What is a Bibliography? The bibliography is an alphabetical list of the sources that you used to research your topic, design the experiment and form the hypothesis.  
Research source 1:
Research source 5:

 Science Fair Guide “Writing the Abstract"


What is a Abstract? The Abstract is a summary of your science fair project. Your abstract is made up of a brief statement of the essential, or most importantly, thoughts about your project. Abstracts should summarize, clearly and simply, the main points of the experiment. Spelling, grammar, punctuation, neatness, and originality are important. It should be 250 to 300 words in length. It is one of the last parts of your science fair project that you will complete. It is an easy part if you are using a computer to record and type your journal entries and other parts of the project. If you are using a computer, then you will only have to cut and paste this information into the abstract.


Include the following to create your abstract:


1.    Your projects purpose statement.

2.   The hypothesis

3.   A description of your variables and the control / constants.

4.   A description of what variable you are manipulating (changing) in your experiment.

5.   How you went about measuring and observing the variables / controls.

6.   Your results and data collected from your experiment.

7.   Your conclusion statement.

A scientific abstract summarize your research paper in a way that helps other researchers determine whether your paper is relevant to their own work. Researchers often use abstracts to decide which papers to acquire, particularly when they are looking for research in an online database that only displays abstracts. While most abstracts are written by the main researcher, you can also use a professional service to write your abstract for you.

  1. 1
    State the purpose of the research very clearly in the first sentence. Think of the research paper as having investigated a particular scientific question. Nothing will be as useful to researchers as knowing exactly what that question was.
  2. 2
    Describe the methodology in the second sentence. The methodology is the way the researchers went about answering the question in sentence one. Methodologies can include experiments or surveys, laboratory or field work, tests on animals or human beings.
  3. 3
    Report the major findings of the research in the third sentence. The researchers would not have written the paper unless they were able to answer the question stated in the first sentence, even if the answer wasn't the one they were expecting or hoping to get.
  4. 4
    Give your interpretation of the impact of the research in the fourth sentence.Tell the reader whether the research will or should produce a change in scientific thinking or practice. In particular, what gap in knowledge has the research filled?
  5. 5
    Count your words. An effective abstract should be between 200 and 300 words long. If it's too short, you can go back and elaborate. However, you still should try to use concise language so the abstract can be easily understood.
  6. 6
    Use past tense sentences, and don't be afraid to use passive voice if necessary. Don't include references to other papers, abbreviations readers may not be familiar with, or any kind of illustration.
  7. 7
    Read the abstract as if you were another researcher deciding whether to read your paper. Do you find that the abstract has the right information to help you make that determination? If not, rewrite it.
