Classroom Microbiology Exercises
A popular class exercise compares hands before and after washing. Students press their fingertips onto agar plates, tape the lids shut, incubate them and count the colonies through the base. Settle plates opened for the same time in a classroom, a kitchen and a corridor give a second comparison. A Gridded Petri Plate makes the counting easier to follow.
Older students can pick a single colony with an Inoculating Loop Nichrome Wire and streak it onto a fresh plate to start a pure culture. All plates go through a Laboratory Autoclave before disposal.
Frequently Asked Questions
Do I mark the colonies on the lid or the base?
Turn the dish over so that the lid rests on the lit pad, and mark each colony on the base. The lid stays on, so the culture is never exposed, and each pen dot shows which colonies are already counted.
Can a single wrong count be taken back?
No. This model has only a reset key, which clears the whole count, so reset and recount if you lose your place. The pen dots on the base make a recount quick. The Microprocessor Colony Counter adds a Correct key, averaging and memory.
What is the Wolffhugel grid for?
The grid divides the dish into squares, so you can work across it row by row without missing colonies. Two students can also count the same plate square by square and compare their totals, which shows where counting errors creep in.
How do I clean the counter after a session?
Wipe the pad, grid and magnifier with a soft cloth lightly dampened with a mild lab disinfectant, never soaking the electronics. Let it dry, then keep it under its dust cover until the next class.
