Investigating the Uses of Backyard Bacteria

Have you ever wanted to know the true structure of E.coli? Does the thought of peering into its "small world" sound exciting? Here is a lesson that allows pupils the ability to do just that. Blossoming microbiologists use microscopes to...

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

What better place to begin learning about life than with a up close an personal look at Earth's oldest living organisms; bacteria. Starting with an examination of the different classifications of bacteria, where they live, what they eat,...

Scientists question how the oceans and the atmosphere get along. An installment in a longer science series investigates this relationship and current research exploring the types of materials that oceans release into the atmosphere....

Students experiment with different bacterias that they found and make predictions of their growth.  In this investigative activity students use petri dishes to grow their bacteria then summarize what has happened. 

Students study food borne illnesses and what foods are more likely to carry them.  In this investigative lesson plan students examine harmful bacteria. 

Here is an unusual comparison: the swimming conditions of a sperm cell and a sperm whale. Introduce your physics class to the Reynolds number by sharing this video comparison during your fluid mechanics unit. Afterward, teach them to...

Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.

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.

Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.
