This article describes low-cost well plates that can be used as alternative kits for microscale experiments. Although ordinary well plates are useful and convenient for microscale experiments, they are not cheap. We have developed well plates composed of plastic bottle caps with approximately 3cm diameter and cardboard containers. Plastic bottle…

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…

The double-wall paper cup is an everyday object that can be used in the laboratory to study heat transfer. The experiment described here has been done by physics students aged 12-13 years; it can also be used in a different context to prompt debate about environmental issues.

Natural products are ubiquitous in nature but do not form a large proportion of the A-level syllabuses in the UK. In this article we briefly discuss a small selection of natural products, focusing on alcohols, aldehydes and ketones, and alkaloids. We then outline two natural product experiments that are suitable for A-level chemistry clubs or…

To improve the quality of education, it is important for teachers to have an understanding of action research. Action research is 'learning by doing', which involves identifying a problem, looking for a plan to resolve it, observing how successful it is and, if not satisfied, trying again. Action research helps educators to be more effective in…

We often say that food and fuels "contain" energy, whereas energy is stored in the fuel-oxygen system generated during photosynthesis. This article suggests revised approaches to teaching that make a clear distinction between matter (food, fuel, oxygen) and energy. (Contains 1 table, 5 boxes, and 6 figures.)

Social media are a highly visible factor in the daily lives of our students. Why should teachers not take advantage of this and develop teaching and learning materials that use the designs found in such media to contextualise science learning? This article suggests some ideas for creating lab instructions using social media design as an innovative…

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…

Discusses five experimental methods used by senior high school students to provide an accurate calibration curve of magnet current against the magnetic flux density produced by an electromagnet. Compares the relative merits of the five methods, both as measurements and from an educational viewpoint. (JR)

Presents experiments, demonstrations, activities and ideas relating to various fields of biology to be used in biology courses in secondary schools. Among those experiments presented are demonstrating the early stages of ferns and mosses and simple culture methods for fern prothalli. (HM)

Describes a laboratory method suitable for senior high school classes for investigating possible mechanisms of catalytic function. The Harcourt-Essen reaction is used to demonstrate a catalytic process that can be investigated quantitatively by standard kinetic methods. (JR)

Suggests that the Friedel-Crafts reaction, used for synthesizing a wide range of aromatic compounds, is an ideal vehicle for extended senior high school project work in chemistry. Provides a theoretical discussion of the reaction, suggests a number of suitable investigations, and outlines the experimental details. (JR)
