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…

Peterson, Elizabeth K.; Carrico, Pauline – Bioscene: Journal of College Biology Teaching, 2015
In this paper, we describe a two-week learning module where students tested the role of the "fruitless" gene on aggression and courtship in "Drosophila melanogaster" via team-based learning (TBL) strategies. The purpose of this module was to determine if TBL could be used in the future as a platform to implement the course…

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…

Weatherred, Wayland; Carlson, Darby J.; Carlson, Kimberly A. – Bioscene: Journal of College Biology Teaching, 2014
Proper hand hygiene accompanied with environmental surface disinfection provides a comprehensive approach to control and prevent respiratory and gastrointestinal illness in schools, hospitals, work environments, and the home. The persistent non-pathogenic Nora virus common in "Drosophila melanogaster" provides a horizontally transmitted…

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…

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…

Shanks, Ryan A.; Southard, E. Megan; Tarnowski, Laura; Bruster, Matthew; Wingate, Stacia W.; Dalman, Nancy; Lloyd, Steven A. – Bioscene: Journal of College Biology Teaching, 2011
This article describes a laboratory experience utilizing videos to engage students in hypothesis-driven experimentation in behavioral neuroscience. It provides students with an opportunity to investigate the effects of chronic methamphetamine exposure on aggression in adult mice using a resident-intruder paradigm. Instructors and students only…

Keyes, Carol A.; Subramanian, Senthil; Yu, Oliver – Bioscene: Journal of College Biology Teaching, 2009
Hairy root transformation has been widely adapted in plant laboratories to rapidly generate transgenic roots for biochemical and molecular analysis. We present hairy root transformations as a versatile and adaptable model system for a wide variety of undergraduate laboratory courses and research. This technique is easy, efficient, and fast making…

Platz, James E. – Bioscene: Journal of College Biology Teaching, 2009
Field experiments offer the opportunity for hands on experience with the scientific process. While this is true of a wide variety of activities, many have pitfalls both experimental and logistical that reduce the overall rate of success, in turn, influencing student learning outcomes. Relying on small, territorial, diurnal lizards and an array of…

Lunsford, Eddie – Bioscene: Journal of College Biology Teaching, 2008
The topic of inquiry is explored in an online freshman level introductory biology course for non-majors. The research took place in a distance learning program at a small community college in the Southeast. Students in the course were required to complete an extended guided inquiry in their homes and to communicate about their work by way of the…

Darling, Randi A. – Bioscene: Journal of College Biology Teaching, 2008
This field experiment is designed to test for despotic behavior in Mallards ("Anas platyrhynchos"), and to examine how ducks distribute themselves relative to their resources. Students present Mallards with food patches differing in profitability in order to examine whether ducks distribute themselves ideal freely or ideal despotically. Students…

Palombi, Peggy Shadduck; Jagger, Kathleen Snell – Bioscene: Journal of College Biology Teaching, 2008
Using cultured fibroblast cells, undergraduate students explore cell division and the responses of cultured cells to a variety of environmental changes. The students learn new research techniques and carry out a self-designed experiment. Through this project, students enhance their creative approach to scientific inquiry, learn time-management and…

Nicholson, Barbara J.; Halkin, Sylvia L. – Bioscene: Journal of College Biology Teaching, 2007
A laboratory exercise is presented in which students determine where metabolic heat is primarily generated in blooming eastern skunk cabbage ("Symplocarpus foetidus") plants. Students consider how color, shape, and orientation of spathes, and stage of flower maturation, may affect metabolic heat production and retention of both metabolic and solar…

Darling, Randi A. – Bioscene: Journal of College Biology Teaching, 2007
This field exercise examines the feeding preferences of Gray Squirrels ("Sciurus carolinensis"). Students present squirrels with a variety of food types in a cafeteria-style arrangement in order to test hypotheses about foraging preferences. This exercise, which is appropriate for introductory biology, ecology, and animal behavior classes, is…

Chemotti, Diana C.; Davis, Sarah N.; Cook, Leslie W.; Willoughby, Ian R.; Paradise, Christopher J.; Lom, Barbara – Bioscene: Journal of College Biology Teaching, 2006
Malathion is an organophosphorus insecticide, which is often sprayed to control mosquitoes. When applied to aquatic habitats, malathion can also influence the embryogenesis of non-target organisms such as frogs and fish. We modified the frog embryo teratogen assay in "Xenopus" (FETAX), a standard toxicological assay, into an investigative…
