Research-Based SAE Programs

Two Types of Research SAEs

You conduct a true experiment in an attempt to solve a problem or learn new knowledge.

You study a problem. Because of the nature of the problem, you cannot perform an experiment.

experimental saes
Experimental SAEs
  • An extensive activity where the student plans and conducts a major agricultural experiment using the scientific process. The purpose of the experiment is to provide "hands-on" experience in:
    • 1. Verifying, learning or demonstrating scientific principles in agriculture.
    • 2. Discovering new knowledge.
    • 3. Using the scientific process.
experimental sae
Experimental SAE
  • Experimental activities are particularly suited for those in agricultural classes where there is a strong emphasis on biotechnology or agriscience. Even in more traditional agricultural programs, experimental SAE activities can provide students whose career goals are in the areas of agriscience with valuable learning experiences.
experimental sae characteristics
Experimental SAE Characteristics
  • There is a control group
    • This is a group of subjects (plants, animals, etc.) that receive no special treatment.
experimental sae characteristics6
Experimental SAE Characteristics
  • There is one or more experimental groups
    • This group (or groups) receive the experimental treatment(s).

Experimental SAE Characteristics
  • Randomization is used
    • Subjects are randomly assigned to groups (both control and experimental groups). If you were doing an experiment with 20 plants, you would randomly divide the plants into two groups of 10.
    • You would randomly pick which group of plants would be the control group and which would receive the experimental treatment.
steps in conducting an experiment
Steps in Conducting an Experiment

1. Identify the problem to be investigated

  • What do you have an interest in?
  • Is there some problem in your community that needs attention?

2. Conduct a thorough review of the literature

  • Read articles in magazines, research journals and on the internet to see what is already known about the problem.
  • Interview people who may have specialized knowledge in the area.
  • Summarize what you have learned.

3. Design the Experiment

  • What will need to done to answer the research question?
  • What treatment(s) will be used?
  • Where will the experiment be conducted?
  • What supplies and materials are needed?
  • How long will it take?
  • What procedures will be followed?

4. Formulate a hypothesis

  • This is your educated guess about the outcome of the experiment.
  • The hypothesis should be directional
    • Treatment A will produced more pounds of gain than treatment B.
    • The experimental group will remain fresh longer than the control group.
    • The weeds sprayed with treatment A will die more quickly than the weeds sprayed with treatments B and C.

6. Collect the Data

  • Regular observations and measurements will need to be made

7. Analyze the data and arrive at conclusions

  • What do all your data (numbers and measurements) mean?
  • What conclusions can be drawn from you experiment?
    • Did one treatment work better than the others?
  • What are your recommendations?

8. Prepare the final report

  • The final report can be a written document describing your research. In writing the report, you should follow the seven steps outlined up to this slide. You will probably want to use charts and graphs to depict your data.
  • A display (like those used in science fairs) is also a good way to show what has been done.
research terminology
Research Terminology
  • Independent Variable – the variable you manipulate, the treatment
    • Temperature
    • Light
    • Acidity
    • Nutrients
    • Soil type
    • Time
    • Magnetic Field
research terminology16
Research Terminology
  • Dependent Variable – the measurement resulting from the application of the independent variable. This is normally some unit of measure.
    • Gain in weight
    • Percent survival
    • Distance traveled per gallon

  • Determining the strength of welds using different welding methods.
experimental sae23
Experimental SAE
  • A quality experimental SAE should:
    • Have specific objectives
    • Follow the scientific process
    • Involve a number of steps
    • Focus on an important agricultural/scientific issue, question or principle
    • Be of sufficient size and scope to assure a quality learning experience
    • Require a moderate to substantial time commitment on the part of the student
    • Be supervised by the teacher
non experimental sae programs
Non-Experimental SAE Programs
  • Some times it is not possible to conduct a true experiment with a control group. Yet, the problem still needs to addressed. Research can still be done.
  • The student gathers and evaluates data from a variety of sources and then produce some type of finished product.
non experimental sae programs25
Non-Experimental SAE Programs
  • A variety of activities can be conducted as analytical or non-experimental SAE projects.
  • The approach taken may be that of:
    • An investigative reporter
    • A detective
    • A journalist
    • An archeologist
    • A documentary producer
non experimental sae examples
Non-Experimental SAE Examples
  • Developing a marketing plan for an agricultural commodity.
non experimental sae examples27
Non-Experimental SAE Examples
  • Writing a series of newspaper articles.
non experimental sae examples28
Non-Experimental SAE Examples
  • Preparing a land use plan for a farm.

non experimental sae
Non-Experimental SAE
  • A non-experimental SAE has all the rigor and steps of an experimental SAE except there is no control group.
    • One will still:
      • Identify a problem
      • Review the literature
      • Develop a plan
      • Conduct the activity
      • Analyze the data
      • Prepare a final report
ffa and research saes
FFA and Research SAEs
  • There are two major FFA programs that recognize student achievement in conducting agriscience SAE programs:
    • Agriscience Student
    • Agriscience Fair
