This collection of worksheets contains some of the experiments which I have used
in my teaching. Feel free to copy them as desired, subject to the conditions below, but
please note that if you intend to use them in your institution you must make the appropriate risk assessments.
The sheets do not have a common format; some have the methods given as bulleted lists,
others are in a more traditional legato style. This is intentional. The
practicals are in no particular order of difficulty.
