Darling, Randi – Bioscene: Journal of College Biology Teaching, 2014
Evolution is a unifying concept within biology. In fact, Dobzhansky, a noted evolutionary biologist, argued, "Nothing in biology makes sense except in the light of evolution" (Dobzhansky, 1973). However, often students have misconceptions about evolution. There are a number of available activities where students use tools (representing…

Jones-Held, Susan; Paoletti, Robert; Glick, David; Held, Michael E. – Bioscene: Journal of College Biology Teaching, 2010
In this article we describe a multi-week investigative laboratory in microbial ecology/diversity and nitrogen cycling that we have used in our introductory biology course. This module encourages active student involvement in experimental design, using the scientific literature and quantitative analysis of large data sets. Students analyze soil…

Parent, Beth A.; Marbach-Ad, Gili; Swanson, Karen V.; Smith, Ann C. – Bioscene: Journal of College Biology Teaching, 2010
Scientific literature was used to give a research oriented context to our immunology lab course. Immunology lab, a senior level course (60 students/year) was formerly taught in a traditional mode, with exercises aimed at learning lab protocols. To engage students in understanding we connected the protocols to their use as reported in research…

Rauter, Claudia M. – Bioscene: Journal of College Biology Teaching, 2010
This laboratory exercise investigates the influence of population density on offspring number and size in burying beetles. Students test the theoretical predictions that brood size declines and offspring size increases when competition over resources becomes stronger with increasing population density. Students design the experiment, collect and…

Lassiter, Christopher S. – Bioscene: Journal of College Biology Teaching, 2010
Monohybrid crosses are taught in biology labs across the country using peas and corn. Students studying monohybrid crosses using zebrafish ("Danio rerio") would encounter a new model organism, and those interested in human or veterinary medicine would have increased interest. To this end, our college has implemented a laboratory exercise at the…

Kowles, Richard V. – Bioscene: Journal of College Biology Teaching, 2010
Cell water relationships are important topics to be included in cell biology courses. Differences exist in the control of water relationships in plant cells relative to control in animal cells. One important reason for these differences is that turgor pressure is a consideration in plant cells. Diffusion and osmosis are the underlying factors…

Smith, Geoffrey R. – Bioscene: Journal of College Biology Teaching, 2010
Using module-based courses has been suggested to improve undergraduate science courses. A course based around a series of modules focused on major environmental issues might be an effective way to teach non-science majors about ecology and ecology's role in helping to solve environmental problems. I have used such a module-based environmental…

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…

Ronsheim, Margaret L.; Pregnall, A. Marshall; Schwarz, Jodi; Schlessman, Mark A.; Raley-Susman, Kathleen M. – Bioscene: Journal of College Biology Teaching, 2009
We describe a new approach to teaching introductory biology. Our introductory experience for undergraduates is a laboratory course that is entirely inquiry and discovery based. We introduce our students to fundamental concepts in biology in the framework of three multi-week laboratory modules, each of which is an open-ended investigation of a…

Cooper, Michael; Dhawale, Shree; Mustafa, Ahmed – Bioscene: Journal of College Biology Teaching, 2009
A straightforward and inexpensive laboratory experiment is presented that investigates the physiological stress response of zebrafish after a 5 degree C increase in water temperature. This experiment is designed for an undergraduate physiology lab and allows students to learn the scientific method and relevant laboratory techniques without causing…

Nordell, Shawn E. – Bioscene: Journal of College Biology Teaching, 2009
Incoming freshmen frequently struggle with the transition from high school to collegiate academics. This appears to be particularly evident in the sciences. Students often lack the self assessment skills and metacognition skills required to self-identify problems with their academic learning strategy. This does not allow them to diagnose and…

Feizabadi, Mitra Shojania – Bioscene: Journal of College Biology Teaching, 2009
The importance of including concepts, examples, and techniques from mathematics and the physical and information sciences in biology courses to fulfill the need of today's undergraduates has been the principle motivation for developing interdisciplinary biology-focused courses. Although this movement started many years ago, developing and offering…

Miller, William R.; Mitchell, Colleen; Miller, Jeffrey D. – Bioscene: Journal of College Biology Teaching, 2009
We challenged an Aquatic Biology class to find a way to access, observe, and record aquatic habitats and organisms without causing disruption. Using off the shelf components the class was guided in the design and assembly of a remote controlled, video broadcasting, data collecting, floating vehicle based on a molded goose decoy. GOOSE-CAM or…

Naples, Virginia L.; Miller, Jon S. – Bioscene: Journal of College Biology Teaching, 2009
Understanding homology is fundamental to learning about evolution. The present study shows an exercise that can be varied in complexity, for which students compile research illustrating the fate of homologous fish skull elements, and assemble a mural to serve as a learning aid. The skull of the most primitive living Actinopterygian (bony fish),…

Pontelli, Enrico; Pinto, Jorge; Qin, Xiaoxiao; He, Jing; Bevan, David; MacCuish, Norah; MacCuish, John; Chapman, Mitch; Moreland, David – Bioscene: Journal of College Biology Teaching, 2009
One of the difficulties in teaching basic molecular biology concepts to the students with little biological background is the lack of hands-on exercises that combines the challenges of the concepts with visualization and immediate feedback. BIOPS Interactive is a web-based interactive learning environment for molecular biology that complements…
