A Basic Microbiology Course for High School Students
[ILLUSTRATION OMITTED] At the high school level, microbiology is not often experienced hands-on in the laboratory Although high school students learn about the properties of microorganisms such as bacteria, fungi, protists, and viruses, and the...
Bacteria Everywhere
It's about time that we stopped being surprised by bacteria. So many articles on these organisms express amazement that bacteria are found where no life was expected to be, or are unbelievably abundant, or have unforeseen capabilities. After so many...
Effective Long-Term Culturing of Paramecia
Paramecia can be quite useful to have in a biology classroom. They provide a great opportunity for students to learn about and view firsthand a living protist that they otherwise would be able to see only in a textbook. Paramecia can be used for feeding...
Environmental Microbiology: Tannins & Microbial Decomposition of Leaves on the Forest Floor
[ILLUSTRATION OMITTED] What happens to the millions of tons of leaves that drop from trees each fall? Why do oak leaves remain intact longer than other trees' leaves? We investigate these questions in an appealing, inquiry-based series of experiments...
Human Activities & the Emergence of Pathogens
The least movement is of importance to all nature. The entire ocean is affected by a pebble. --Blaise Pascal Many infectious diseases were unknown to hunter and gatherer populations, in which the small size of groups, combined with their nomadic...
Investigation of Essential Oils as Antibiotics
[ILLUSTRATION OMITTED] Several essential oils have been demonstrated to contain antibacterial compounds. Hammer et al. (1999) found that tea tree oil has antibacterial and antiviral properties. The tea tree (Melaleuca alternifolia) is native to...
It's a Small World after All ... a Microcosm ... Tell the Kids!
[ILLUSTRATION OMITTED] They are on us, in us, and left by us in an identifiable trail on whatever we touch and wherever we go (Forensics). They cause our childhood tonsillitis, strep throat, and ear and urinary tract infections, bloom in our cuts...
Teaching Basic Lab Skills Using Diverse Microbial Communities in a Biologically Relevant Context
[ILLUSTRATION OMITTED] Traditionally, introductory laboratory courses that use microbiological techniques have a medical focus and tend to use pure cultures to teach basic lab skills (Leboffe & Pierce, 2006). Consequently, students get comparatively...
Using the Wolbachia Bacterial Symbiont to Teach Inquiry-Based Science: A High School Laboratory Series
[ILLUSTRATION OMITTED] Humans consist of approximately 10% human cells and 90% prokaryotic cells, yet the idea of studying the varied relationships between eukaryotic hosts and prokaryotic symbionts is largely ignored in introductory biology classes....
