Guided-Inquiry Labs Using Bean Beetles for Teaching the Scientific Method & Experimental Design
Peer reviewed Peer reviewed
Direct linkDirect link
Schlueter, Mark A.; D'Costa, Allison R. – American Biology Teacher, 2013
Guided-inquiry lab activities with bean beetles ("Callosobruchus maculatus") teach students how to develop hypotheses, design experiments, identify experimental variables, collect and interpret data, and formulate conclusions. These activities provide students with real hands-on experiences and skills that reinforce their understanding of the…

The Tongue Map, Real or Not?
Peer reviewed Peer reviewed
Direct linkDirect link
Marshall, Pamela A. – American Biology Teacher, 2013
Students need practice in proposing hypotheses, developing experiments that will test these hypotheses, and generating data that they will analyze to support or refute them. I describe a guided-inquiry activity based on the "tongue map" concept, appropriate for middle school and high school students.

Using Trypsin & Soybean Trypsin Inhibitor to Teach Principles of Enzyme Kinetics
Peer reviewed Peer reviewed
Direct linkDirect link
Howard, David R.; Herr, Julie; Hollister, Rhiannon – American Biology Teacher, 2006
Trypsin and soybean trypsin inhibitor (Kunitz inhibitor) can be used in a relatively simple and inexpensive student exercise to demonstrate the usefulness of enzyme kinetics. The study of enzyme kinetics is essential to biology because enzymes play such a crucial role in the biochemical pathways of all living organisms. The data from enzyme…

Quantification in an Introductory Diffusion Experiment.
Peer reviewed Peer reviewed
Snow, George E. – American Biology Teacher, 1991
Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)

Motion Picture and Videotape Analysis of Behavior.
Peer reviewed Peer reviewed
Carpenter, Geoffrey C.; Duvall, David – American Biology Teacher, 1983
Use of motion pictures and videotape recordings to analyze animal behavior is described. Indicates that accuracy/amount of data available is greatly increased and that simultaneous behaviors of different animals can be studied or individual behavior patterns increased/decreased, providing observers with temporal perceptions similar to the animals…
