Browning, Samantha; Urschler, Margaret; Meidl, Katherine; Peculis, Brenda; Milanick, Mark – Bioscene: Journal of College Biology Teaching, 2017
We describe a 3-hour session that provides students with the opportunity to review basic lab concepts and important techniques using real life scenarios. We began with two separate student-engaged discussions to remind/reinforce some basic concepts in physiology and review calculations with respect to chemical compounds. This was followed by…

Ryan, Amy B.; Elwess, Nancy L. – Bioscene: Journal of College Biology Teaching, 2017
This investigative laboratory activity engages students in observing, recording, graphing and analyzing pulsation rates in a commonly used laboratory organism, blackworms. This activity stresses how various drugs can impact the pulsation rate in blackworms at varying concentrations. In addition, we have incorporated two new ways to view the…

Cross, Chrissy J. – Bioscene: Journal of College Biology Teaching, 2017
In the undergraduate biology laboratory, many freshmen are apathetic towards the content of the course. Curriculum based reader's theater (CRBT) is an instructional method that can increase interest the students in the content of the course while improving student communication, collaboration and understanding. This research is an examination of…

Berkes, Charlotte; Chan, Leo Li-Ying – Bioscene: Journal of College Biology Teaching, 2015
We have developed a semester-long laboratory project for an undergraduate immunology course in which students study multiple aspects of macrophage biology including differentiation from progenitors in the bone marrow, activation upon stimulation with microbial ligands, expression of cell surface markers, and modulation of cytokine production. In…

Kudish, Philip; Schlag, Erin; Kaplinsky, Nicholas J. – Bioscene: Journal of College Biology Teaching, 2015
We developed a multi-week laboratory in which college-level introductory biology students investigate Mendel's stem length phenotype in peas. Students collect, analyze and interpret convergent evidence from molecular and physiological techniques. In weeks 1 and 2, students treat control and experimental plants with Gibberellic Acid (GA) to…

Nogaj, Luiza A. – Bioscene: Journal of College Biology Teaching, 2014
A nine-week laboratory project designed for a sophomore level molecular biology course is described. Small groups of students (3-4 per group) choose a tumor suppressor gene (TSG) or an oncogene for this project. Each group researches the role of their TSG/oncogene from primary literature articles and uses bioinformatics engines to find the gene…

Basey, John M.; Maines, Anastasia P.; Francis, Clinton D.; Melbourne, Brett – Bioscene: Journal of College Biology Teaching, 2014
We examined the effects of documenting observations with digital imaging versus hand drawing in inquiry-based college biodiversity labs. Plant biodiversity labs were divided into two treatments, digital imaging (N = 221) and hand drawing (N = 238). Graduate-student teaching assistants (N = 24) taught one class in each treatment. Assessments…

Pearce, Amy R.; Sale, Amanda Lovelace; Srivatsan, Malathi; Beck, Christopher W.; Blumer, Lawrence S.; Grippo, Anne A. – Bioscene: Journal of College Biology Teaching, 2013
We developed an inquiry-based biology laboratory exercise in which undergraduate students designed experiments addressing whether material from the neem tree ("Azadirachta indica") altered bean beetle ("Callosobruchus maculatus") movements and oviposition. Students were introduced to the bean beetle life cycle, experimental…

Belanger, Rachelle M.; Conant, Stephanie B.; Grabowski, Gregory M. – Bioscene: Journal of College Biology Teaching, 2013
Rats can be used as a model organism to teach physiological concepts in a laboratory setting. This article describes a two-part laboratory that introduces students to hypothesis testing, experimental design, the appropriate use of controls and surgical techniques. Students perform both a castration and sham-control surgery on male rats and test…

Roy, Nicole M. – Bioscene: Journal of College Biology Teaching, 2013
RNA interference (RNAi) is a powerful technology used to knock down genes in basic research and medicine. In 2006 RNAi technology using "Caenorhabditis elegans" ("C. elegans") was awarded the Nobel Prize in medicine and thus students graduating in the biological sciences should have experience with this technology. However,…

Hallyburton, Chad L.; Lunsford, Eddie – Bioscene: Journal of College Biology Teaching, 2013
The history of learning biology through distance education is documented. A review of terminology and unique problems associated with biology instruction is presented. Using published research and their own teaching experience, the authors present recommendations and best practices for managing biology in distance-based formats. They offer ideas…

Fingerut, Jonathan; Orbe, Kristina; Flynn, Daniel; Habdas, Piotr – Bioscene: Journal of College Biology Teaching, 2013
As part of a biomechanics course aimed at both upper-division Biology and Physics majors, this laboratory exercise introduces students to the ingenious ways in which organisms vary the composition and form of support and defensive structures such as bone and shell to maximize their strength while minimizing the energetic cost needed to produce…

Daggett, Melissa A. F. – Bioscene: Journal of College Biology Teaching, 2012
A number of current reports are challenging educators of undergraduate biology students to increase the role, interactions and approaches of other disciplines. The goal stated in these reports is to produce a college graduate with the skills and competencies to solve pressing global problems such as producing ample food, fuels, and making health…

Shultz, Jeff – Bioscene: Journal of College Biology Teaching, 2011
I have devised a method with which a molecular size standard can be readily manufactured using Lambda DNA and PCR. This method allows the production of specific sized DNA fragments and is easily performed in a standard molecular biology laboratory. The material required to create these markers can also be used to provide a highly robust and…

Hill, Brent J. F.; Goodman, Ian; Moran, William M. – Bioscene: Journal of College Biology Teaching, 2011
Most undergraduate physiology texts describe veins simply as reservoirs for blood and conduits for return of blood to the heart. This article describes a laboratory exercise that can be performed by students to demonstrate that veins are much more than reservoirs and conduits for blood flow: they possess a dynamic rhythmic contraction. In this…
