Osenkowski, Pamela; Green, Che; Tjaden, Anne; Cunniff, Peggy – American Biology Teacher, 2015
Animal dissection has been routinely practiced in American biology classrooms for decades. With technological advancements, more states adopting student choice measures, and increased awareness about ethical concerns surrounding dissection, many useful dissection alternatives have been developed. To understand the current use of animal dissection…

Hubler, Tina; Adams, Patti; Scammell, Jonathan – American Biology Teacher, 2015
The molecular basis of evolution is an important and challenging concept for students to understand. In a previous article, we provided some of the scientific background necessary to teach this topic. This article features a series of laboratory activities demonstrating that molecular events can alter the genomes of organisms. These activities are…

Setty, Sumana; Kosinski-Collins, Melissa S. – American Biology Teacher, 2015
It has been noted that undergraduate project-based laboratories lead to increased interest in scientific research and student understanding of biological concepts. We created a novel, inquiry-based, multiweek genetics research project studying Ptpmeg, for the Introductory Biology Laboratory course at Brandeis University. Ptpmeg is a protein…

Simpson, Jeff S. – American Biology Teacher, 2014
Because of shrinking budgets and computerized virtual dissection programs, many large and small institutions are closing the door on traditional and expensive cadaver dissection classes. However, many health-care educators would argue there is still a place for cadaver dissection in higher education, so the continuing challenge is to provide the…

Stuart, Parker E.; Lees, Kelsey D.; Milanick, Mark A. – American Biology Teacher, 2014
In this practice-based lab, students are provided with four Olympic athlete profiles and simulated blood and urine samples to test for illegal substances and blood-doping practices. Throughout the course of the lab, students design and conduct a testing procedure and use their results to determine which athletes won their medals fairly. All of the…

Falteisek, Lukáš; Cerný, Jan; Janštová, Vanda – American Biology Teacher, 2013
To involve students in thinking about the problem of AIDS (which is important in the view of nondecreasing infection rates), we established a practical lab using a simplified adaptation of Thomas's (2004) method to determine the polymorphism of HIV co-receptor CCR5 from students' own epithelial cells. CCR5 is a receptor involved in inflammatory…

Peters, Brenda J.; Blair, Amy C. – American Biology Teacher, 2013
Many biology educators at the undergraduate level are revamping their laboratory curricula to incorporate inquiry-based research experiences so that students can directly participate in the process of science and improve their scientific reasoning skills. Slugs are an ideal organism for use in such a student-directed, hypothesis-driven experience.…

Reardon, Ryan A.; Sharer, J. Daniel – American Biology Teacher, 2012
This report describes a novel, inquiry-based learning plan developed as part of the GENA educational outreach project. Focusing on mitochondrial genetics and disease, this interactive approach utilizes pedigree analysis and laboratory techniques to address non-Mendelian inheritance. The plan can be modified to fit a variety of educational goals…

Benskin, Jon; Chen, Sixue – American Biology Teacher, 2012
As advances in biotechnology and molecular biology rapidly expand in research settings, it is vital that we continue to prepare high school students to enter and thrive in those modern laboratories. This multistep, inquiry-based lab describes highly adaptable methods to teach students not only current molecular techniques and technologies, but…

Bokor, Julie – American Biology Teacher, 2012
Practicing correct pipetting procedure doesn't have to be boring. "Pipetting by Coordinates" is an effective way to teach necessary pipetting skills in an enjoyable manner. Students create designs as they add volumes of colored water to specific wells and gain experience using a basic biotechnology tool.

Grammer, Robert T. – American Biology Teacher, 2012
We propose a procedure for the assay of fermentation in yeast in microcentrifuge tubes that is simple and rapid, permitting assay replicates, descriptive statistics, and the preparation of line graphs that indicate reproducibility. Using regression and simple derivatives to determine initial velocities, we suggest methods to compare the effects of…

Corotto, Frank; Ceballos, Darrel; Lee, Adam; Vinson, Lindsey – American Biology Teacher, 2010
Students commonly test the effects of chemical agents on the heart rate of the crustacean "Daphnia" magna, but the procedure has never been optimized. We determined the effects of three concentrations of ethanol, nicotine, and caffeine and of a control solution on heart rate in "Daphnia." Ethanol at 5% and 10% (v/v) reduced mean heart rate to…

Herron, Sherry S. – American Biology Teacher, 2009
As described in "How People Learn," "Developing Biological Literacy," and by the Commission on Undergraduate Education in the Biological Sciences during the 1960s and early 1970s, laboratories should promote guided-inquiries or investigations, and not simply consist of cookbook or verification activities. However, the only word that could describe…

Marvel, Stephen C.; Kepler, Megan V. – American Biology Teacher, 2009
It is important for students to be exposed to the concept of osmotic pressure. Understanding this concept lays the foundation for deeper discussions that lead to more theoretical aspects of water movement associated with the concepts of free energy, water potential, osmotic potential, pressure potential, and osmotic adjustment. The concept of…

Clopton, Joe R. – American Biology Teacher, 2008
For teachers, a common difficulty when introducing scientific thinking is finding ways to engage the participation of the students. Because most scientific problems require at least some specialized knowledge to formulate and solve, it can be hard to go beyond merely discussing the steps of the scientific method and illustrating them with the…
