Turano, Morgan A.; Lobuono, Cinzia; Kirschenbaum, Louis J. – Journal of Chemical Education, 2015
Although metal spatulas are damaged through everyday use and become discolored and corroded by chemical exposure, plastic drinking straws are inexpensive, sterile, and disposable, reducing the risk of cross-contamination during laboratory procedures. Drinking straws are also useful because they come in a variety of sizes; narrow sample containers…

Cranwell, Philippa B.; Peterson, Alexander M.; Littlefield, Benjamin T. R.; Russell, Andrew T. – Journal of Chemical Education, 2015
An operationally simple, reliable, and cheap Sonogashira reaction suitable for an undergraduate laboratory class that can be completed within a day-long (8 h) laboratory session has been developed. Cross-coupling is carried out between 2-methyl-3-butyn-2-ol and various aryl iodides using catalytic amounts of bis(triphenylphosphine)palladium(II)…

Chapman, Peter; Glasser, Leslie – Physics Teacher, 2015
The mechanics of a beam balance are little appreciated and seldom understood. We here consider the conditions that result in a stable balance, with center of gravity below the fulcrum (pivot point), while an unstable balance results when the center of gravity is above the fulcrum. The highly sensitive drinking-straw microbalance, which uses a…

Bojesen, Emile – Educational Philosophy and Theory, 2015
This paper attempts to reintegrate the concept of plasticity into educational philosophy. Although John Dewey used the concept in Democracy and Education (1916) it has not generated much of a critical or practical legacy in educational thought. French philosopher, Catherine Malabou, is the first to think plasticity rigorously and seriously in a…

Teaching Science, 2015
This project is for a team of students (groups of two or three are ideal) to design and construct a model of a single-span bridge, using plastic drinking straws as the building material. All steps of the design, construction, testing and critiquing stages should be recorded by students in a journal. Students may like to include labelled diagrams,…

Crawford, Elizabeth O.; Luke, Nancy; Van Pelt, William – International Journal of Early Childhood Environmental Education, 2015
"'Do You Want Paper or Plastic?' An Inquiry into Single-Use Grocery Bags" is an inquiry-based, solutions-focused environmental education unit developed for the U.S. Fund for UNICEF. Field-tested in two U.S. southeastern regions, the unit engages students as informed change makers who investigate the production, consumption, and disposal…

Arican, Muhammet – International Journal of Science and Mathematics Education, 2018
The purpose of this study was to investigate eight preservice middle and high school mathematics teachers' solution strategies when solving single and multiple proportion problems. Real-world missing-value word problems were used in an interview setting to collect information about preservice teachers' (PSTs) reasoning about proportional…

Porat, Gilit; Kapon, Shulamit – Physics Teacher, 2018
Although the teaching of mechanics at advanced K12 levels often starts with a brief introduction to physical quantities and units, the nature and function of measurements in physics and their inherent uncertainty are hardly ever discussed. The laboratory is mainly used to illustrate the theoretical principles taught in class. This paper presents a…

Rossetti, Christian L. – Decision Sciences Journal of Innovative Education, 2018
The described exercise uses competition and the promise of a sugar-high to motivate students to appreciate the importance load management in an intermodal setting. Using material available from a local supermarket or general merchandise store, student teams load their "container" for two customers. One customer requires palletized square…

Walther, Ashley; Chai, Weiwen; Dunker, Tara; Franzen-Castle, Lisa; Krehbiel, Michelle – Afterschool Matters, 2018
Out-of-school time (OST) programs serve youth from diverse demographic backgrounds. OST programs, whose informal settings provide opportunities for experiential learning, can address this problem by implementing nutrition and food-preparation programming to improve participants' dietary knowledge and behaviors. In this article, the authors…

Tamburini, Fiona; Kelly, Thomas; Weerapana, Eranthie; Byers, Jeffery A. – Journal of Chemical Education, 2014
Paper to Plastics (P2P) is an interdisciplinary program that combines chemistry and biology in a research setting. The goal of this project is 2-fold: to engage students in scientific research and to educate them about sustainability and biodegradable materials. The scientific aim of the project is to recycle unwanted office paper to the useful…
