Students isolate three species of bacteria using the plate streak method, implement sterile microbiology techniques, and produce pure cultures of each microorganism at the end of this exercise. They write a descriptive paragraph for each...

Students experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables the student to determine the originator of the "epidemic." They transfer live bacteria by hand contact, then...

Students use an experiment that allows them to experience a small scale "epidemic", demonstrating the ease with which disease organisms are spread. Students determine the originator of the epidemic. They transfer live bacteria by hand...

In this irradiation worksheet, students simulate the effects of irradiation on bacteria growth by using UV light. Then students complete 6 short answer questions.

Young scholars observe intra-species variation by completing standard microbial streaking procedures. They collect data from which they draw observations and complete a worksheet.
