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…

Kao, Robert M. – American Biology Teacher, 2014
A major challenge in teaching organ development and disease is deconstructing a complex choreography of molecular and cellular changes over time into a linear stepwise process for students. As an entry toward learning developmental concepts, I propose two inexpensive hands-on activities to help facilitate learning of (1) how to identify defects in…

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…

Howard, Ava R. – American Biology Teacher, 2014
Use of real specimens brings the study of biology to life. This activity brings easily acquired plant specimens into the classroom to tackle common alternative conceptions regarding life, size, complexity, the nature of science, and plants as multicellular organisms. The activity occurs after a discussion of the characteristics of life and engages…

Simmons, Alexandria D.; Larios-Sanz, Maia; Amin, Shivas; Rosell, Rosemarie C. – American Biology Teacher, 2014
Anyone who has taught an introductory biology lab has sat at their desk in front of a towering stack of lengthy lab reports and wondered if there was a better way to teach scientific writing. We propose the use of a one-page format that we have called a "mini-report," which we believe better allows students to understand the structure…

Offner, Susan – American Biology Teacher, 2014
New phylogenomic tools have made it possible to construct a robust phylogenetic tree of mollusks. This tree can be used to teach important evolutionary principles.

Green, Michelle L.; Novakofski, Jan; Green, Ryan W.; Manjerovic, Mary Beth; Mateus-Pinilla, Nohra – American Biology Teacher, 2014
Providing both introductory information and biosecurity protocols in laboratory, farm, and field settings is central to student learning and safety. However, even when clear protocols are provided, students do not fully understand the consequences of their actions. We present a crime scene that requires evidence investigation to improve basic…

Scherer, Yvette D. – American Biology Teacher, 2014
In this activity, students are given the opportunity to combine skills in math and geometry for a biology lesson in the cell cycle. Students utilize the data they collect and analyze from an online onion-root-tip activity to create a paper-plate time clock representing a 24-hour cell cycle. By dividing the paper plate into appropriate phases of…

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…

Cohen, Joel I. – American Biology Teacher, 2014
A standard part of biology curricula is a project-based assessment of cell structure and function. However, these are often individual assignments that promote little problem-solving or group learning and avoid the subject of organelle chemical interactions. I evaluate a model-based cell project designed to foster group and individual guided…

Calmer, Joseph; Straits, William – American Biology Teacher, 2014
As a science teacher, I regularly use outside reading assignments (e.g., news articles) to help develop my students' understanding of topics addressed in my anatomy class. However, I have found that in simply reading texts, students often fail to (1) understand the context of the science discussed, (2) make the connections between ideas…

Hudson, Margaret L. – American Biology Teacher, 2014
Heart valves play a vital role in efficient circulation of the blood, and the details of their physical structure are related crucially to their function. However, it can be challenging for the learner to make the mental connection between anatomical structures of valves and the changing pressure gradients that the valves experience and come to an…

Romero, Chris; Choun, James – American Biology Teacher, 2014
This activity provides students an interactive demonstration of the electron transport chain and chemiosmosis during aerobic respiration. Students use simple, everyday objects as hydrogen ions and electrons and play the roles of the various proteins embedded in the inner mitochondrial membrane to show how this specific process in cellular…

Chudyk, Sarah; McMillan, Amy; Lange, Catherine – American Biology Teacher, 2014
This article contains an original 5E lesson plan developed from conservation genetics research on the giant North American hellbender salamander, Cryptobranchus alleganiensis alleganiensis. The lesson plan provides background information on the hellbender, reviews basic genetics, and exposes students to the scientific process that is used during…

Romesburg, H. Charles – American Biology Teacher, 2014
This article explains four kinds of inquiry exercises, different in purpose, for teaching advanced-level high school and college students the hypothetico-deductive (H-D) method. The first uses a picture of a river system to convey the H-D method's logic. The second has teams of students use the H-D method: their teacher poses a hypothesis…
