Be sure to include information like the volume of tests, instruments used and education required. Or set up a blood typing display so visitors can find out their blood type and learn about the procedures used in the laboratory. For a school career day, you could create an exhibit that explains the role of technologists, technicians and pathologists - include the education required and employment outlook. Bring an exciting message to viewers. Video tapes have been used successfully at many exhibits because it opens dramatically - then delivers a clear, easily understood message.
Demonstration is a great teaching method.
Let your audience peer down the microscope and examine slides or actually cut tissue with a microtome. Vendors may be willing to lend or donate equipment and supplies. Add an element of luck to your exhibit with a drawing for appropriate prizes. You might get donations of movie tickets or dinners for two from local theaters and restaurants. Be sure exhibit staffers are well trained, can answer questions on whatever topic you have chosen, and have the patience, enthusiasm, and charisma for dealing with guests.
