Chemistry Prelab Format
Chemistry is a laboratory science and involves a good deal of
experimental work in the lab. In order
for you to receive the maximum benefit from your lab work you must be prepared
to do the experiment when you arrive in class.
In addition, since lab texts could be easily damaged during lab work,
you will not be allowed to use your lab texts during the experiment. As a result, you will be required to do a
written prelab before entering the lab to do an experiment.
A prelab includes the following:
a. PURPOSE:
A very brief explanation of what you are going to accomplish in doing
the experiment. One
or two sentences will usually be enough. The first paragraph in the lab
text usually explains
the purpose of the lab.
b. EQUIPMENT LIST:
A list of all lab equipment (glassware, etc.) that you will use during
the experiment. (Do not
include chemicals used in the lab, just lab equipment). This will allow you to get everything
ready before you begin the experiment and will save you time. List the equipment in one or
two COLUMNS rather than in a paragraph.
c.
PROCEDURE:
A list of the steps you will take to complete the experiment. This should be in YOUR OWN
WORDS, and contain ENOUGH DETAIL so that you do not have to use the lab
text. Number
the steps the same as in the lab text.
d. DATA TABLE:
A separate sheet of paper to be used as a data table. The data table should be prepared ahead
so that it is ready to accept data from the experiment.
You will NOT be allowed to do the lab
activity until you have completed the prelab. Missed lab time will be made up after school or at tutorial.
