Principles of Chemistry Laboratory

The Unwritten Rules

• If an experiment works, something has gone wrong.

• When you don't know what you're doing, do it neatly.

• Experiments must be reproduceable, they should fail the same way each time.

• First draw your curves, then plot your data.

• Experience is directly proportional to equipment ruined.

• Always keep a record of your data. It indicates that you have been working.

• To do a lab really well, have your report done well in advance.

• If you can't get the answer in the usual manner, start at the answer and derive the question.

• In case of doubt, make it sound convincing.

• Do not believe in miracles: rely on them.

• Team work is essential, it allows you to blame someone else.

• All unmarked beakers contain fast-acting, extremely toxic poisons.

• No experiment is a complete failure. At least it can serve as a negative example.

• Any delicate and expensive piece of glassware will break before any use can be made of it.
