What is it?
This “Streak Plate” interactive is based on the 4th lab exercise for this class. You must sterilize a wire loop, acquire a bacteria sample, and drag it across a petri dish, thrice, in order to create clumps of pure bacteria. This interactive ends with an image of the growth results, and a checklist of the various (dozens of) steps.
The real world lab requires an overnight incubation period, and students often make mistakes along the way, so it was ideal to let them practice on their own.
