How to plan an experiment
First, make sure you know what you’re trying to find out. In this case, it is…
To measure the optimum temperature for respiration in yeast.
There is absolutely no point in stating this again as the “aim” or “introduction”. It merely wastes time, paper, ink and
effort. What you should do first, however – before launching into a detailed description of how or why – is OUTLINE the
procedure to be used so that the reader has some idea what is going on. You could include the diagram (which, if complete
will get you P4b) at this stage. Something like this:
Outline
A sample of yeast will be suspended in glucose solution in a boiling tube. The carbon dioxide produced by respiration will
be bubbled through water and the rate of bubbling used as a measure of the rate of respiration. The reaction tube will be
kept in a water bath at a constant temperature for each run and the experiment will be repeated at a range of temperatures.
