Hodgson, Jay Y. S.; Mateer, Scott C. – American Biology Teacher, 2015
The compound microscope is an important tool in biology, and mastering it requires repetition. Unfortunately, introductory activities for students can be formulaic, and consequently, students are often unengaged and fail to develop the required experience to become proficient in microscopy. To engage students, increase repetition, and develop…

Bouwma-Gearhart, Jana; Bouwma, Andrew – American Biology Teacher, 2015
The "Next Generation Science Standards" (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the…

Tseng, ChingMei; Chen, Shu-Bi Shu-Bi; Chang, Wen-Hua – American Biology Teacher, 2015
Guiding students to generate testable scientific questions is essential in the inquiry classroom, but it is not easy. The purpose of the BDC ("Big Idea, Divergent Thinking, and Convergent Thinking") instructional model is to to scaffold students' inquiry learning. We illustrate the use of this model with an example lesson, designed…

Schultheis, Elizabeth H.; Kjelvik, Melissa K. – American Biology Teacher, 2015
Current educational reform calls for increased integration between science and mathematics to overcome the shortcomings in students' quantitative skills. Data Nuggets (free online resource, http://datanuggets.org) are worksheets that bring data into the classroom, repeatedly guiding students through the scientific method and making claims…

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…

Sturner, Kelly; Lucci, Karen – American Biology Teacher, 2015
This inquiry-based activity for high school students introduces concepts of ecology and the importance of data analysis to science. Using an investigative case, students generate independent questions about birds, access Cornell Lab of Ornithology online resources to collect data, organize and graph data using Excel, and make claims based on…

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…

Casady, Grant M. – American Biology Teacher, 2015
Undergraduate biology labs often explore the techniques of data collection but neglect the statistical framework necessary to express findings. Students can be confused about how to use their statistical knowledge to address specific biological questions. Growth in the area of observational ecology requires that students gain experience in…

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…

Royer, Anne M.; Schultheis, Elizabeth H. – American Biology Teacher, 2014
Evolutionary experiments are usually difficult to perform in the classroom because of the large sizes and long timescales of experiments testing evolutionary hypotheses. Computer applications give students a window to observe evolution in action, allowing them to gain comfort with the process of natural selection and facilitating inquiry…

Chen, Ying-Chih; Steenhoek, Joshua – American Biology Teacher, 2014
Argumentation is now seen as a core practice for helping students engage with the construction and critique of scientific ideas and for making students scientifically literate. This article demonstrates a negotiation model to show how argumentation can be a vehicle to drive students to learn science's big ideas. The model has six phases:…

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…

Weigel, Emily G.; DeNieu, Michael; Gall, Andrew J. – American Biology Teacher, 2014
This lesson is designed to teach students that behavior is a trait shaped by both genes and the environment. Students will read a scientific paper, discuss and generate predictions based on the ideas and data therein, and model the relationships between genes, the environment, and behavior. The lesson is targeted to meet the educational goals of…

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…
