General tips

A properly prepared lab proposal clearly states the objective(s) of your research (poses the question), clearly describes your experimental design (the precise steps you will follow), anticipates specific kinds and quantities of materials needed to perform your experiment, and indicates expected outcomes based upon your background reading and sound biological judgement, etc. By thinking through your experimental procedure and writing a good proposal, the actual implementation phase will be enjoyable and orderly. However, remember that the steps you take during the actual experiment are recorded in your log because they may not be exactly like the steps suggested in your proposal. Proposed and actual procedures may be two different things. The latter are the most important because they determine whether or not you will be able to repeat the experiment exactly as you performed it the first time. At no time will you enter actual experimental data on proposal forms. Use the logs for this (see instructions elsewhere about this). An alternative hypothesis will be included because your results may not be as predicted. The question to ask is: What should the experimental design be for a follow-up experiment if the results of the first one are negative?

Some attributes of a good proposal

  • Contains a clearly stated question that can be answered scientifically; Identifies the proper scientific name of the organism (or object of your work) and the dependent and independent variables.
  • The title is put in the form of a statement rather than a question. Thus, Question: Does temperature affect the rate of oxygen production in the aquatic plant, Elodea ? Statement (Title of work): The Effect of Temperature on the Rate of Oxygen Production in the aquatic plant, Elodea.
  • Contains a clear but brief explanation of experiment; Describes the essential plan of your research and what you hope to find out, (a brief version of your experimental design).
  • Specifies and details materials needed in kinds and numbers. Consult instructor when in doubt (a good time to finalize a proposal is at the "proposal conference" with the instructor). Poor: We will need beakers, salt and a couple of rulers. Better: Materials Needed - a. 500 ml beakers - 3 b. 10% stock solution of NaCl - 500 ml c. Meter sticks - 2
  • Methods: after reading, thinking and consulting, list step by step the process you will follow in carrying out your experiment to the best of your ability, as if you are actually performing the experiment.
  • Includes sketches of tables that will be entered into logs to receive data consistent with the methods proposed. Will the tables be suitable? Are they correctly labeled to identify the variables?
  • Includes an alternative hypothesis.

    Proposal Submission Form

    Below is components usually found in a proposal. Copy this and paste it into a word processor and fill in the blanks.


    Proposal

    Lab day and time: ______________ Group number _________________

    Group members: ____________________________________________

    Question:

    Statement of Purpose or Hypothesis:

    Materials Needed:

    Methods: Indicate step-by-step specifically what you are going to do; make sure to explicitly identify the variables by name.

    Table Design: To be entered into your individual lab notebook to receive data generated by your experiment.

    Data Analysis: Describe any special data analysis that will be necessary to prepare the data for the lab report.
