Celius, Tevye C.; Peterson, Ronald C.; Anderson-Wile, Amelia M.; Kraweic-Thayer, Mitchell – Journal of Chemical Education, 2018
In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

Meek, Simon J.; Pitman, Catherine L.; Miller, Alexander J. M. – Journal of Chemical Education, 2016
An introductory guide to deducing the mechanism of chemical reactions is presented. Following a typical workflow for probing reaction mechanism, the guide introduces a wide range of kinetic and mechanistic tools. In addition to serving as a broad introduction to mechanistic analysis for students and researchers, the guide has also been used by…

Jones, Thomas C.; Laughlin, Thomas F. – American Biology Teacher, 2010
Natural selection and other components of evolutionary theory are known to be particularly challenging concepts for students to understand. To help illustrate these concepts, we developed a simulation model of microevolutionary processes. The model features all the components of Hardy-Weinberg theory, with population size, selection, gene flow,…

Anacleto, Joaquim; Pereira, Mario G. – European Journal of Physics, 2009
Using macroscopic thermodynamics, the general law for adiabatic processes carried out by an ideal gas was studied. It was shown that the process reversibility is characterized by the adiabatic reversibility coefficient r, in the range 0 [less than or equal] r [less than or equal] 1 for expansions and r [greater than or equal] 1 for compressions.…

de Abreu, Rodrigo; Guerra, Vasco – European Journal of Physics, 2009
The null result of the Michelson-Morley experiment and the constancy of the one-way speed of light in the "rest system" are used to formulate a simple problem, to be solved by elementary geometry techniques using a pair of compasses and non-graduated rulers. The solution consists of a drawing allowing a direct visualization of all the fundamental…

Nopparatjamjomras, Suchai; Chitaree, Ratchapak; Panijpan, Bhinyo – Physics Education, 2009
To overcome students' inaccurate prior knowledge on primary additive colours, a coloured-light mixer has been constructed to enable students to observe directly the colours produced and reach the conclusion by themselves that the three primary colours of light are red, green, and blue (NOT red, yellow, and blue). Three closely packed tiny…

Heck, Andre; Vonk, Ron – Physics Education, 2009
Physics teachers often like to discuss physics concepts with their students on the basis of simple demonstration experiments. In this article, we discuss an experiment for which one only needs a few coins of the same denomination and a wooden stick: the coins are laid alongside the stick on a horizontal surface, the stick is rotated about one of…

Iniguez, J.; Raposo, V. – European Journal of Physics, 2009
In this paper we analyse the behaviour of a small-scale model of a magnetic levitation system based on the Inductrack concept. Drag and lift forces acting on our prototype, moving above a continuous copper track, are studied analytically following a simple low-speed approach. The experimental results are in good agreement with the theoretical…

Essen, Hanno; Apazidis, Nicholas – European Journal of Physics, 2009
We study the turning point problem of a spherical pendulum. The special cases of the simple pendulum and the conical pendulum are noted. For simple initial conditions the solution to this problem involves the golden ratio, also called the golden section, or the golden number. This number often appears in mathematics where you least expect it. To…

Dewanto, Andreas; Hea, Roland Su Jong – Physics Education, 2009
We report a school project which equips students with both theoretical and practical knowledge in material physics. We construct dumpling skins from a mixture of flour and water. A series of experiments is then conducted to quantify the toughness, hardness, and tensile strength of the skins, and how they are affected by adding other materials into…

Gragson, Derek E.; Beaman, Dan; Porter, Rhiannon – Journal of Chemical Education, 2008
Two experiments are described in which students explore phase transitions and critical phenomena by obtaining compression isotherms of phospholipid monolayers using a Langmuir trough. Through relatively simple analysis of their data students gain a better understanding of compression isotherms, the application of the Clapeyron equation, the…

Peterson, Karen I. – Journal of Chemical Education, 2008
The experiment developed in this article addresses the concept of equipment calibration for reducing systematic error. It also suggests simple student-prepared sucrose solutions for which accurate densities are known, but not readily available to students. Densities are measured with simple glassware that has been calibrated using the density of…

Battino, Rubin; Letcher, Trevor M. – Journal of Chemical Education, 2008
The cryophorus dramatically demonstrates the cooling effect of evaporation. This article describes some simple and easy-to-make cryophoruses, ideal for demonstrating evaporative cooling to students at all levels. The most dramatic effects occurred with cyclohexane and benzene, with water generally freezing more slowly. (Contains 4 notes, 2 tables,…

Chyan, Yieu; Chyan, Oliver – Journal of Chemical Education, 2008
In this lab experiment, screen-printed electrode strips are used to illustrate the essential concepts of electrochemistry, giving students an opportunity to explore metal electrodeposition processes. In the past, metal electrodeposition experiments were seldom included in general chemistry labs because of the difficulty of maintaining separate…

Deschaine, J. S.; Suits, B. H. – European Journal of Physics, 2008
Normal mode solutions for the perfectly flexible hanging cord problem have been known for over 200 years. More recently, theoretical results for a hanging cord with a point mass attached were presented. Here the theoretical results are tested experimentally using high-precision techniques which are accessible for use in an introductory laboratory.…
