Charles K. Jervis

o increase students’ understanding of biology, biochemistry, and microbiology, Mr. Jervis and Ms. Jervis implement a study of cyanobacteria, unicellular aquatic and photosynthetic bacteria, and biofilms, resilient layers formed by bacterial colonies. Students identify and collect biofilms and design a system for controlled testing and monitoring of the biofilms that can be continued by future classes. Working with the biochemistry department of Virginia Polytechnic Institute and State University, students monitor and document colonization and successional changes in the biofilm. Students develop and conduct a scientific seminar to demonstrate their learning in an authentic format.
