Claycomb, James R.; Zachary, Christopher; Tran, Quoc – Physics Teacher, 2009
Rocket experiments demonstrating conservation of momentum will never fail to generate enthusiasm in undergraduate physics laboratories. In this paper, we describe tests on rockets from two vendors that combine baking soda and vinegar for propulsion. The experiment compared two analytical approximations for the maximum rocket height to the…

Brown, Douglas; Cox, Anne J. – Physics Teacher, 2009
The value of video analysis in physics education is well established, and both commercial and free educational video analysis programs are readily available. The video format is familiar to students, contains a wealth of spatial and temporal data, and provides a bridge between direct observations and abstract representations of physical phenomena.…

Malago, Wilson, Jr.; Soares-Costa, Andrea; Henrique-Silva, Flavio – Biochemistry and Molecular Biology Education, 2009
In 1928, Frederick Griffith demonstrated a transmission process of genetic information by transforming "Pneumococcus". In 1944, Avery et al. demonstrated that Griffith's transforming principle was DNA. We revisited these classic experiments in a practical class for undergraduate students. Both experiments were reproduced in simple, adapted forms.…

Sulzinski, Michael A.; Wasilewski, Melissa A.; Farrell, James C.; Glick, David L. – Biochemistry and Molecular Biology Education, 2009
It is an extraordinary challenge to offer an undergraduate laboratory course in virology that teaches hands-on, relevant molecular biology techniques using nonpathogenic models of human virus detection. To our knowledge, there exists no inexpensive kits or reagent sets that are appropriate for demonstrating real-time PCR (RT-PCR) in an…

Betush, Matthew P.; Murphree, S. Shaun – Journal of Chemical Education, 2009
Chiral oxazolidinone chemistry is used as a framework for an advanced multi-step synthesis lab. The cost-effective and robust preparation of chiral starting materials is presented, as well as the use of chiral auxiliaries in a synthesis scheme that is appropriate for students currently in the second semester of the organic sequence. (Contains 1…

Burns, Kristi L.; Oldham, Charlie D.; May, Sheldon W. – Journal of Chemical Education, 2009
As part of a multidisciplinary course that is cross-listed between five departments, we developed an undergraduate student laboratory experiment for culturing, isolating, and purifying the biopolymer, poly(3-hydroxybutyrate), PHB. This biopolyester accumulates in the cytoplasm of bacterial cells under specific growth conditions, and it has…

Ouyang, Liming; Ge, Chongtao; Wu, Haizhen; Li, Suxia; Zhang, Huizhan – Biochemistry and Molecular Biology Education, 2009
Individual genome DNA was extracted fast from oral swab and followed up with PCR specific for codon 248 of "p53" tumor suppressor gene. "Msp"I restriction mapping showed the G-C mutation in codon 248, which closely relates to cancer susceptibility. Students learn the concepts, detection techniques, and research significance of point mutations or…

McNaught, Ian J.; Peckham, Gavin D. – Journal of Chemical Education, 2009
The method given in many publications for calculating the solubility product of potassium bitartrate is wrong in principle. A way of modifying the experimental approach and calculations to overcome the problem are presented.

Carson, Tobin M.; Bradley, Sharonda Q.; Fekete, Brenda L.; Millard, Julie T.; LaRiviere, Frederick J. – Journal of Chemical Education, 2009
Recent advances in canine genomics have allowed the development of highly distinguishing methods of analysis for both nuclear and mitochondrial DNA. We describe a laboratory exercise suitable for an undergraduate biochemistry course in which the polymerase chain reaction is used to amplify hypervariable regions of DNA from dog hair and saliva…

McKenzie, Lallie C.; Huffman, Lauren M.; Hutchison, James E.; Rogers, Courtney E.; Goodwin, Thomas E.; Spessard, Gary O. – Journal of Chemical Education, 2009
A major approach for implementing green chemistry is the discovery and development of synthetic strategies that reduce the quantity of solvent needed, eliminate it altogether, or rely on new reaction media. An increasing number of examples have demonstrated that greener reaction solvents or media can enhance performance as well as reduce hazard.…

Linn, Marcia C.; Eylon, Bat-Sheva – Routledge, Taylor & Francis Group, 2011
"Science Learning and Instruction" describes advances in understanding the nature of science learning and their implications for the design of science instruction. The authors show how design patterns, design principles, and professional development opportunities coalesce to create and sustain effective instruction in each primary scientific…

Garces, Andres; Sanchez-Barba, Luis Fernando – Chemistry Education Research and Practice, 2011
We describe an alternative educational approach for an inorganic chemistry laboratory module named "Experimentation in Chemistry", which is included in Industrial Engineering and Chemical Engineering courses. The main aims of the new approach were to reduce the high levels of failure and dropout on the module and to make the content match the…

Pardo, Richard; Parker, Jennifer – Science Teacher, 2010
In the lesson presented in this article, students learn to organize their thinking and design their own inquiry experiments through careful observation of an object, situation, or event. They then conduct these experiments and report their findings in a lab report, poster, trifold board, slide, or video that follows the typical format of the…

Nivens, Delana A.; Padgett, Clifford W.; Chase, Jeffery M.; Verges, Katie J.; Jamieson, Deborah S. – Journal of Chemical Education, 2010
Case studies and current literature are combined with spectroscopic analysis to provide a unique chemistry experience for art history students and to provide a unique inquiry-based laboratory experiment for analytical chemistry students. The XRF analysis method was used to demonstrate to nonscience majors (art history students) a powerful…

Li, Suxia; Wu, Haizhen; Zhao, Jian; Ou, Ling; Zhang, Yuanxing – Biochemistry and Molecular Biology Education, 2010
In an effort to achieve high success in knowledge and technique acquisition as a whole, a biochemistry and molecular biology experiment was established for high-grade biotechnology specialty students after they had studied essential theory and received proper technique training. The experiment was based on cloning and expression of alkaline…
