Choi, Annette; Wang, Mengqi; Hrizo, Stacy; Buckley, Martin S. – Biochemistry and Molecular Biology Education, 2018
Exposure of organisms to high temperatures and various chemical and physical stressors can cause protein misfolding and aggregation. In turn, this can disrupt the functions of proteins, threatening both development and homeostasis. To overcome this, cells can initiate the highly conserved heat shock (HS) stress response pathway. In eukaryotes,…

McKernan, Lisa N. – American Biology Teacher, 2015
The challenge of teaching in the sciences is not only conveying knowledge in the discipline, but also developing essential critical thinking, data analysis, and scientific writing skills. I outline an exercise that can be done easily as part of a microbiology laboratory course. It teaches the nature of the research process, from asking questions…

Rose, Chantelle M.; Adams, Jacqueline M.; Hinchey, Elizabeth K.; Nestlerode, Janet A.; Patterson, Mark R. – Science Activities: Classroom Projects and Curriculum Ideas, 2013
Pressure increases rapidly with depth in a water body. Ocean and Great Lakes scientists often use this physical feature of water as the basis of a fun pastime performed aboard research vessels around the world: the shrinking of polystyrene cups. Depending on the depth to which the cups are deployed, the results can be quite striking! Capitalizing…

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…

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…

Bell, Ellis – Biochemistry and Molecular Biology Education, 2011
A course design for first-year science students is described, where the focus is on the skills necessary to do science. The course uses original research projects, designed by the students, to teach a variety of skills including reading the scientific literature, hypothesis development and testing, experimental design, data analysis and…

Green, William P.; Trotochaud, Alan; Sherman, Julia; Kazerounian, Kazem; Faraclas, Elias W. – Journal of Chemical Education, 2009
The quantization of electronic energy levels in atoms is foundational to a mechanistic explanation of the periodicity of elemental properties and behavior. This paper presents a hands-on, guided inquiry approach to teaching this concept as part of a broader treatment of quantum mechanics, and as a foundation for an understanding of chemical…

Leang, K. K.; Zou, Q.; Pannozzo, G. – IEEE Transactions on Education, 2010
Piezoelectric actuators (or piezoactuators) are known for their nanoresolution and high-speed positioning capabilities. Therefore, they are used in scanning probe microscopes and in the design of innovative surgical tools and biomedical devices. The expected growth of engineering jobs in the nano- and bio-related fields, in which piezoactuators…

Buffler, Andy; Lubben, Fred; Ibrahim, Bashirah – International Journal of Science Education, 2009
The present study explores the relationship between students' views of the nature of science (NOS) and their views of the nature of scientific measurement. A questionnaire with two-tier diagnostic multiple-choice items on both the NOS and measurement was administered to 179 first-year physics students with diverse school experiences. Students'…

Platz, James E. – Bioscene: Journal of College Biology Teaching, 2009
Field experiments offer the opportunity for hands on experience with the scientific process. While this is true of a wide variety of activities, many have pitfalls both experimental and logistical that reduce the overall rate of success, in turn, influencing student learning outcomes. Relying on small, territorial, diurnal lizards and an array of…

Rettig, Jessica E.; Smith, Geoffrey R. – Journal of College Science Teaching, 2009
Research-like experiences range from relatively "canned" labs that are highly controlled by the instructor (such as those described in Lord and Orkwiszewski 2006) to more individually designed projects (e.g., Switzer and Shriner 2000; Wyatt 2005). This article describes a laboratory approach that allows for many of the benefits of independent or…

Furge, Laura Lowe; Fletke, Kyle J. – Biochemistry and Molecular Biology Education, 2007
Cytochrome P450 enzymes are a family of heme-containing proteins located throughout the body with roles in metabolism of endogenous and exogenous compounds. Among exogenous compounds, clinically relevant pharmaceutical agents are nearly all metabolized by P450 enzymes. However, the activity of the different cytochrome P450 enzymes varies among…

Koray, Ozlem; Koksal, Mustafa Serdar – Asia-Pacific Forum on Science Learning and Teaching, 2009
The purpose of this study was to examine the effect of creative and critical thinking based laboratory method on prospective primary teachers' creative and logical thinking abilities. This research was conducted with 90 prospective elementary school teachers who were enrolled in two classes of education faculty during the spring semester of the…

Ray, Andrew M.; Beardsley, Paul M. – Science Activities: Classroom Projects and Curriculum Ideas, 2008
Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…

Bonds, Wesley D., Sr.; Paolella, Mary Jane – American Biology Teacher, 2006
A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…
