The Next-Lab project provides free web-based resources supporting teachers in enhancing students' learning experiences. By including online laboratories, experiments otherwise difficult or impossible to perform are facilitated (e.g. crashing meteoroids into Earth). This article briefly presents the project and opportunities offered to teachers and…

We sometimes struggle with the question of whether our primary goal is for students to recall or understand answers to questions, or for students to do science and improve their "scientific temper". This article describes how an enquiry-based laboratory experiment was carried out in which the stress was on the latter. The students…

This article describes how a university and a museum have worked together to create a "How science works" workshop entitled "What's in our water?" The workshop teaches students about the continuing pollution from a disused coal mine, how the pollution is cleaned up using a state-of-the-art treatment works and how scientists…

Short reports contributed on a variety of biology topics are presented. (CP)

Short reports contributed on a variety of topics in chemistry are presented. (CP)

A variety of topics in physics are covered by these contributed teaching and laboratory equipment suggestions. (CP)

Presents a teaching unit on the Langmuir absorption isotherm suitable for advanced secondary school chemistry classes. Describes the experimental investigation of the isothermal adsorption of sulfur dioxide on charcoal, and discusses the derivation of the Langmuir equation and some applications. (JR)

Describes the procedure for making a quantitative analysis of organic compounds suitable for secondary school chemistry classes. Using the Schoniger procedure, the organic compound, such as PVC, is decomposed in a conical flask with oxygen. The products are absorbed in a suitable liquid and analyzed by titration. (JR)

Topics in biology A-level projects are briefly described. (CP)

Contends that demonstration lecturing is a valuable science teaching approach. Highlights the benefits of this technique and identifies sources of information for teachers. Provides a listing of popular science lectures suitable for chemistry classes. Describes in detail the "Major of Chemistry" demonstration. (ML)

Contains contributed suggestions in the teaching of structure and bonding and reaction rates and equilibria in the Nuffield Advanced Chemistry Project. (CP)

Describes a variety of experiments that can be performed using the disposable syringe. Among others, these include the removal of oxygen during rusting, convection in a liquid and in air, gas collection in an electrolysis cell, small scale production of a fog, and hydrogen/oxygen extraction from a voltameter. (JR)

Provides a reading list for A- and S-level biology. Contains several experiments and demonstrations with topics on: the intestine, bullock corneal cells, valences, the science of tea, automated hydrolysis, electronics characteristics, bromine diffusion, enthalpy of vaporization determination, thermometers, pendulums, hovercraft, Bernoulli fluid…
