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…

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…

Hewitt, Krissi M.; Kayes, Lori J.; Hubert, David; Chouinard, Adam – American Biology Teacher, 2014
Recent reform initiatives in undergraduate biology call for curricula that prepare students for dealing with real-world issues and making important links between science and society. In response to this call, we have developed an issues-based laboratory module that uses guided inquiry to integrate the concepts of animal behavior and population…

Drits-Esser, Dina; Malone, Molly; Barber, Nicola C.; Stark, Louisa A. – American Biology Teacher, 2014
Epigenetics is the study of how external factors and internal cellular signals can lead to changes in the packaging and processing of DNA sequences, thereby altering the expression of genes and traits. Exploring the epigenome introduces students to environmental influences on our genes and the complexities of gene expression. A supplemental…

Redelman, Carly V.; Marrs, Kathleen; Anderson, Gregory G. – American Biology Teacher, 2012
In nature, bacteria exist in and adapt to different environments by forming microbial communities called "biofilms." We propose simple, inquiry-based laboratory exercises utilizing a biofilm formation assay, which allows controlled biofilm growth. Students will be able to qualitatively assess biofilm growth via staining. Recently, we developed a…

Venditti, Jennifer J.; Surmacz, Cynthia A. – American Biology Teacher, 2012
In this guided inquiry, students explore the complex hormonal regulation of the female reproductive cycle using inexpensive ovulation and pregnancy detection kits that are readily available over the counter. This hands-on activity engages students in the practice of doing science as highlighted by the "National Science Education Standards." The…

Shodell, Michael – American Biology Teacher, 2010
It is certainly widely appreciated that there is much to be gained in the fertile crosstalk between science and history--whether bringing a historical perspective into the science classroom (Wieder, 2006) or a scientific perspective to the study of history (McElvaine, 2002; Smail, 2008). Perhaps the major impetus for using history in teaching…

Riechert, Susan E.; Post, Brian K. – American Biology Teacher, 2010
The national Science, Technology, Engineering, and Math (STEM) Education Initiative favors a curriculum shift from the compartmentalization of math and science classes into discrete subject areas to an integrated, multidisciplinary experience. Many states are currently implementing programs in high schools that provide greater integration of math,…

Hochberg, Robert; Gabric, Kathleen – American Biology Teacher, 2010
The "new biology" of the 21st century is increasingly dependent on mathematics, and preparing high school students to have both strong science and math skills has created major challenges for both disciplines. Researchers and educators in biology and mathematics have been working long hours on a project to create high school teaching modules…

Marquard, Robert D.; Steinback, Rebecca – American Biology Teacher, 2009
Major advances in fundamental science are developed using model systems. Classic examples of model systems include Mendel's work with the common garden pea ("Pisium sativa"), classic inheritance work by Morgan with the fruit fly ("Drosophila"), developmental studies with the nematode ("C. elegans"), and transposable elements in maize ("Zea…

Clay, Tansy W.; Fox, Jennifer B.; Grunbaum, Daniel; Jumars, Peter A. – American Biology Teacher, 2008
The authors have developed and field-tested high school-level curricular materials that guide students to use biology, mathematics, and physics to understand plankton and how these tiny organisms move in a world where their intuition does not apply. The authors chose plankton as the focus of their materials primarily because the challenges faced…

Dahl, John; Mixter, Phil – American Biology Teacher, 2008
In delivering a core science course to pre-health-related majors, the authors sought ways to engage students, make material relevant to life-long learning, and present it in a memorable way. Their goals were to present scientific content fused with history, ethics, public policy, and art in such a way that the students would be provided a unique…

Whiteley, Andrew R.; Woolfe, Jennifer; Kennedy, Kathleen; Oberbillig, David; Brewer, Carol – American Biology Teacher, 2007
Mark-recapture techniques are commonly used by ecologists to estimate abundance of naturally occurring animals and are an important component of ecology curricula. This investigation teaches a mark-recapture technique using store-bought crickets in 10-gallon aquaria and provides an inexpensive way to teach students about mark-recapture in a real…

Baram-Tsabari, Ayelet; Yarden, Anat – American Biology Teacher, 2007
Identifying students' interests in biology can play an important role in improving existing curricula to meet their needs. An analysis of 1,751 self-generated biological questions raised by children, adolescents, and adults yielded data regarding the different age groups' interests in biology. Research limitations and applications for teaching are…

Nassif, Thomas Harttung; Zeller, Nancy – American Biology Teacher, 2006
Humans have long pondered the question of life's origins on Earth and sought to understand their place in the vast expanse of the Universe. Are they alone, in which case the inception of life is a phenomenon unique to planet Earth, or will they find signs of life on other terrestrial bodies? Today, technology allows space probes and rovers to…
