Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Young scholars are able to name one kind of harmful bacteria and why it hurts us and also name one kind of helpful bacteria and how we use it. They describe the process of growing bacterial cultures in a lab. Students create a reasonable...

Antibiotics kill bacterial growth, but widespread use results in antibiotic resistance. Researchers wonder if quorum sensing might allow us to treat bacteria without the resistance. View an animation of quorum sensing as it regulates...

Students explore scientific method and scientific investigation They conduct an investigation using bacteria and antibiotics. In addition, they verbalize their experimental results.

Students explain the benefits and harm caused by bacteria in the body. In this biology activity, students observe bacterial growth in the lab. They explain why anti-bacterial soap may not be beneficial for the human body.

Students demonstrate safe ways to handle bacteria, prepare agar plates, and grow bacterial cultures. They identify different kinds of bacterial colonies, and devise a controlled experiment.

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

A nicely formatted set of slides that logically follow and define the structure and function of the genes in Bacteria. The repressor proteins and other gene regulators are listed and diagrams support the explanations of their function on...

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....

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...
