Bacteria Sampling

This Bacteria Sampling interactive also includes:

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results. Then, they visit a milk processing plant and swab tanks to gather samples and repeat the experiment. Finally, pupils learn how to use the process of bacterial sampling to determine how many colonies exist.
