Project Must Use Scientific Method
  • Observation- Select a topic.
  • Question- Ask a question about what you observe.
  • Hypothesis- Predict an answer to your question.
  • Method - Decide on a way to test the hypothesis.
    The outcome must be measurable.
  • Result- Conduct experiment using defined method
    and record the results. Always repeat research
    to confirm results.
  • Conclusion- State whether your prediction was
    confirmed or not and try to explain your results.

Getting Started
  • Selecting a Research Topic
  • Choose a topic of interest
  • Realistic
  • (student abilities, knowledge, resources and
  • Select topic matches closely to SAE
  • Seek a topic that can be expanded
  • National winning projects (long term 2-3 year
    with performed replications more data

Selecting a Topic
  • Get Ideas Resources
  • Websites search
  • Current newspaper, magazines, Educational TV
  • Librarians, Federal, State, County and Local
  • Visit a university and speak to professors or
    graduate students involved in topic
  • Contact industrial firms doing research in topic

Present Research
  • Effect of Colored Mulch on Tomato Root Growth

  • Don't hesitate to ask. If you are interested,
    most people will assist you.
  • It is very important to keep a complete
    bibliography of all material found and a list of
    people who helped.

Question After you decide on a topic, you need a
Narrow down your field of research. It is
important to focus on one question. Some
Guidelines What have you always wanted to know
in that area? Choose a question that can be
answered with a YES or a NO. What are
researchers asking in that area?
Rememberthe first requirement of a scientist is
  • If a world-class physicist can spend hours
    figuring out the way curve balls work and the
    speed at which they work best, don't assume any
    question you come up with is too lowly to

Construct Theory Base
  • Search for items that will enable you to build an
    argument that the proposed research project is
    necessary and will make a contribution to the
    body of knowledge that already exists
  • Internet
  • Books
  • Magazines
  • College of Agriculture
  • Experiment Stations
  • Extension Service
  • Agribusiness

Students Research Proposal
  • Statement of the problem
  • Purpose and objectives of research
  • Summary of previous research
  • Method How experiment will be set up in order
    to solve the problem
  • Data collection Procedures for collecting and
    analyzing data
  • Assumptions what is your best guess hypothesis
    concerning the outcome of the experiment
  • Limitations Define any limitations that might
    impact outcome
  • Definition of Terms for person reading paper
    with no previous knowledge of subject area
  • Bibliography

  • What do you think may be the answer to your
    question, how the project will turn out?
  • The hypothesis is the possible answer you will
    try to prove or disprove.
  • There is no right or wrong answer here.
  • As the project progresses, try to determine if
    hypothesis is true.

Decide on a procedure method How will you go
about doing the experiment?
  • Method will be the process by which the
    hypothesis is proved or disproved.
  • Compile a list of all the materials needed to
    conduct investigation. Keep track of costs.
  • While doing experiment, keep very accurate
    records of all steps tests performed.
  • Record failures as well as successes.

Record your results
  • Use a notebook to record all information or data.
  • Make charts and graphs, draw pictures or use
    videotape to show results.
  • Give facts, not opinions.
  • If experiment uses measurements, then give those
    exact measurements.
  • Do not use terms like about, more or less, close
    to, etc.

Record the Results
  • What was the result of the experiment?
  • Have you eliminated all variables?
  • (conditions which could affect the answer but for
    which you are not testing)
  • Repeat experiment to ensure accuracy validity.
  • It is recommend that experiment be repeated a
    minimum of 8 times to validate.

Conclusion Write a final report summarizing your
question, research methods and conclusion.
  • The conclusion is the answer to your question.
  • Should be clear, concise and stick to the point.
  • Resist the temptation to jump to conclusions.
  • What did your project teach you?

Conclusionaddress these questions
  • If you were to do your experiment again, would
    you get the same results?
  • Can there be differences? Why?
  • What happened when you tested your hypothesis.
  • Even if the experiment proved your hypothesis
    wasn't true, you've learned something. What is
    your project's importance?
  • What have you learned?

  • Prepare a winning display

Winning Display
  • Prepare a display to give your audience a quick
    overview of
  • the question you asked, the method you used, the
    result you got, and the conclusion you came to
  • Draw charts, diagrams or illustrations to explain
    your question, methods and results
  • A neat and organized poster will obviously
    communicate your work better than a sloppy,
    disorganized one.

Include within Display
  • Notebook
  • Includes the nitty-gritty details of the
  • Make sure it is complete the information in it
  • Demonstration Materials
  • Items that illustrate a scientific principle,
    equipment or materials used, or enable others to
    retrace your steps
  • Hands-on" will make an exhibit more interesting
    and help others understand your discovery
  • Use photographs to illustrate your work if your
    experiment involves valuable equipment or animals
    dangerous chemicals that are not allowed

Horticulture Related Agriscience Projects

  • Study of plant life, agronomy, horticulture,
    forestry, plant taxonomy, plant physiology,
    pathology, genetics, hydroponics, algae, etc.
