Copper is isolated from a 5-cent coin with the help of electrolysis. This experiment is useful for conceptual understanding of the significance of reduction potentials in situation of competition for electrons.

The water absorption in chickpeas (dried legumes) is analyzed. The chickpea experiment serves as an introduction to the concepts of osmosis, mass transfer and diffusion.

Surface tensions gradients were generated in a thin liquid film because of the local increase in temperature, for demonstration purposes. This is performed using a simple experiment and allows different alternatives for heat generation to be used.

Complexes of pyrazole-derived ligands are very popular due to the ability of the pyrazolato anion to form bridged polymetallic compounds in which the metals are held close enough to react with small molecules or facilitate magnetic exchange. The preparation of monodentate pyrazole and 3,5-dimethylpyrazole (DMHpz) nickel species and the…

The development of an FI analyzer for chemiluminescence detection using a low-cost photoiodide is presented. The experiment clearly demonstrates in a single interdisciplinary project the way in which different aspects in chemical instrumentation fit together to produce a working analytical system.

The two things that usually attract students include sports and observing the unexpected. These activities which can be adapted for any class investigating the physical property of density, addresses both using an interactive, cross-disciplinary, open-ended investigation centered on determining mathematically whether a bowling ball will sink or…

An experiment, in which students were given the opportunity to perform molecular dynamics simulations on a series of molecular liquids using the Amber suite of programs, is presented. They were introduced to both physical theories underlying classical mechanics simulations and to the atom-atom pair distribution function.

Digital versatile disks (DVDs) have successfully made up an inexpensive but high-resolution spectroscope suitable for classroom experiments that can easily be made with common material and gives clear and fine spectra of various light sources and colored material. The observed spectra can be photographed with a digital camera, and such images can…

An experiment is conducted for obtaining quantum dots for physical or materials chemistry. This experiment serves to both reinforce the basic concept of quantum confinement and providing a useful bridge between the molecular and solid-state world.

The emergence of molecular tools in multiple disciplines has elevated the importance of undergraduate laboratory courses that train students in molecular biology techniques. Although it would also be desirable to provide students with opportunities to apply these techniques in an investigative manner, this is generally not possible in the…

Attitudes to science scales developed earlier in England have been used in and around a Pakistan city with children in Primary/Elementary Grades 4-8. The limitations of a "transferred scale" in a culturally different context are apparent in a failure to reproduce the English factor patterns, but items are identified to serve as a base…

This article presents a lesson plan in which students learn about water in solid, liquid, and gaseous phases through trade books, demonstrations, and artwork. The author illustrates the stages of the lesson plan in the sequence they were conducted in the classroom with a group of students in grades one and two. Each stage targets specific learning…

This article describes a discovery experiment for general chemistry and organic chemistry labs. Although the pinacol rearrangement has been employed in undergraduate organic laboratories before, in this application organic chemistry students act as mentors to students of general chemistry. Students work together using distillation--a new technique…

The present state of information communication technology makes it possible to devise and run computer-based e-laboratories accessible to any user with a connection to the Internet, equipped with very simple technical means and making full use of web services. Thus, the way is open for a new strategy of physics education with strongly global…

In this study our goal was to better understand the development of chemistry teachers who are involved in a continuous professional development (CPD) programme, focusing on using the inquiry approach in the chemistry classroom-laboratory, followed by protocols assembled in a portfolio that can be used to demonstrate evidence-based practice in…
