PURPOSE. Test the accuracy of the hypothesis that the pre-lab grades given by the TA are inversely proportional to the amount of work/preparation done.
PROCEDURE. Handed in several pre-labs done in the style required by the syllabus (type 1), which stated "a pre-lab consists of the title, date, purpose, brief procedure and data charts for the experiment." Handed in one pre-lab grade, not done in the style required by the syllabus and done with minimal effort and preparation (type 2). Compared grades from each type of pre-lab.
RESULTS AND OBSERVATIONS. Type 1 pre-labs came back with an average grade of 1.25/3. The Type 2 pre-lab came back with a grade of 3/3.

RESULTS AND OBSERVATIONS. Type 1 pre-labs came back with an average grade of 1.25/3. The Type 2 pre-lab came back with a grade of 3/3.
DISCUSSION. Type 1 pre-labs were done over the course of an hour (per pre-lab). A careful reading of the lab manual was done prior to the pre-lab writing process. Each Type 1 pre-lab was between 1/2 and 3/4 pages long and included a title, date, purpose, brief procedure and any necessary data chart. The Type 2 pre-lab was done in a five-minute window before the lab class. Minimal reading of the lab manual was done prior to the pre-lab writing process. The Type 2 pre-lab was less than 1/2 page long.
CONCLUSION. The results support the hypothesis that pre-lab grades are inversely proportional to the amount of work/preparation done.

I had a similar experience in chemistry. It pissed me off to no end.
On the other hand, once I figured it out, I has a lot more free time right before lab. =/
