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…

Briju, Betsy J.; Wyatt, Sarah E. – American Biology Teacher, 2015
Instructors often present Mendelian genetics and molecular biology separately. As a result, students often fail to connect the two topics in a tangible manner. We have adopted a simple experiment to help link these two important topics in a basic biology course, using red and white onions bought from a local grocery store. A lack of red coloration…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

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…

Valauri-Orton, Alexis; Bernd, Karen K. – American Biology Teacher, 2015
For many middle school students, connections between their lives and concepts like chemical reactivity, microbial contamination, and experimental sampling are not obvious. They may also feel that, even if there were connections, understanding the monitoring and quality of natural resources is something for grown-ups and beyond their…

Lampert, Evan C.; Morgan, Jeanelle M. – American Biology Teacher, 2015
Diverse communities of arthropods and microbes provide humans with essential ecosystem goods and services. Arthropods are the most diverse and abundant macroscopic animals on the planet, and many remain to be discovered. Much less is known about microbial diversity, despite their importance as free-living species and as symbionts. We created…

Pecor, Keith W.; Lake, Ellen C.; Wund, Matthew A. – American Biology Teacher, 2015
Optimal foraging theory attempts to explain the foraging patterns observed in animals, including their choice of particular food items and foraging locations. We describe three experiments designed to test hypotheses about food choice and foraging habitat preference using bird feeders. These experiments can be used alone or in combination and can…

Galloway, Katelyn; Anderson, Nadja – American Biology Teacher, 2014
"Cootie Genetics" is a hands-on, inquiry-based activity that enables students to learn the Mendelian laws of inheritance and gain an understanding of genetics principles and terminology. The activity begins with two true-breeding Cooties of the same species that exhibit five observable trait differences. Students observe the retention or…

Bowling, Bethany; Zimmer, Erin; Pyatt, Robert E. – American Biology Teacher, 2014
Although the development of next-generation (NextGen) sequencing technologies has revolutionized genomic research and medicine, the incorporation of these topics into the classroom is challenging, given an implied high degree of technical complexity. We developed an easy-to-implement, interactive classroom activity investigating the similarities…

Taylor, John R. – American Biology Teacher, 2014
This simple inquiry-based lab was designed to teach the principle of osmosis while also providing an experience for students to use the skills and practices commonly found in science. Students first design their own experiment using very basic equipment and supplies, which generally results in mixed, but mostly poor, outcomes. Classroom "talk…

Unsworth, Elizabeth – American Biology Teacher, 2014
Identification of macromolecules in food is a standard introductory high school biology lab. The intent of this article is to describe the conversion of this standard cookbook lab into an inquiry investigation. Instead of verifying the macromolecules found in food, students use their knowledge of the macromolecules in food to determine the…

Holding, Matthew L.; Denton, Robert D.; Kulesza, Amy E.; Ridgway, Judith S. – American Biology Teacher, 2014
A fundamental component of science curricula is the understanding of scientific inquiry. Although recent trends favor using student inquiry to learn concepts through hands-on activities, it is often unclear to students where the line is drawn between the content and the process of science. This activity explicitly introduces students to the…

Suwa, Tomomi; Williamson, Brad – American Biology Teacher, 2014
We present a guided-inquiry biology lesson, using the plant-rhizobium symbiosis as a model system. This system provides a rich environment for developing connections between the big ideas in biology as outlined in the College Board's new AP Biology Curriculum. Students gain experience with the practice of scientific investigation, from…

Weeks, Andrea; Bachman, Beverly; Josway, Sarah; Laemmerzahl, Arndt F.; North, Brittany – American Biology Teacher, 2014
In order to challenge our undergraduate students' enduring misconception that plants, animals, and fungi must be "advanced" and that other eukaryotes traditionally called protists must be "primitive," we have developed a 24-hour take-home guided inquiry and investigation of live Physarum cultures. The experiment replicates…

Machtinger, Erika T. – American Biology Teacher, 2014
Hands-on activities with live organisms allow students to actively explore scientific investigation. Here, I present activities that combine guided inquiry with direct instruction and relate how nutrition affects the physiology and behavior of the common housefly. These experiments encourage student involvement in the formulation of experimental…
