The Jurassic Coast is Britain's only natural World Heritage site, a tangible time-line that takes one through 185 million years of history in 95 miles of coast. It provides individuals with a world-famous educational resource and an unrivalled outdoor classroom that has played a key role in the study of earth sciences. The author is keen to ignite…

Provides instructions and advice on growing the edible mushrooms (Agaricus bisporus) in school. Also suggests several classroom activities using these mushrooms. (JN)

Background information on the biology of aphids is supplied. Using this information in a wide variety of investigations, many involving equipment and techniques available in the school laboratory, can be carried out. An appendix lists possible projects. (Author)

Describes a field exercise which links ecology and taxonomy in the teaching of the species concept. Two common hedgerow plants (red and white campions) are used as a pair of "species" that are normally distinct. Plants of intermediate character can be encountered, and the status of these plants is investigated. (Author/JN)

Describes outdoor biology activities in a woodland area at a private boys school in England. Activities included studies of areas within the woods, winter trips, and wood and pond animals. Includes comments on preparing for and teaching the activities. (Author/JN)

Telecom link is a structured design exercise concerned with building a telecommunications link between London and Amsterdam. Designed for A-level physics, the simulation requires a minimum of 10 hours. Aims of the exercise, design specifications and technical aspects, and summaries of four possible technologies used in the simulation are…

Describes a chemistry "trail" (similar to a nature trail) which focuses on chemical phenomena in the environment. The trail includes 20 stops in and around a local school. Types of phenomena examined include building materials, air pollution, corrosion of metals, swimming pools, and others. Additional activities are also suggested. (DH)

Describes water-related activities in an elementary school science project. Activities focus on mini aquaria, permanent aquaria, water toys, sea power, imagination, and village ponds. (DH)

Suggests a threefold rationale for practical work in science: in developing laboratory skills, in learning to work as a scientist, and in acquiring a feel for phenomena. Three types of pupil practical work (exercises, investigations, and experiences) are then discussed. (Author/JN)

Discusses some of the problems encountered in teaching electronics in British secondary schools with regard to understanding certain concepts. Describes some ways of teaching the concept of potential in a secondary electronics course. (TW)

Discusses methods used in the biological assessment of river quality and such indicators of clean and polluted waters as the Trent Biotic Index, Chandler Score System, and species diversity indexes. Includes a summary of a river classification scheme based on quality criteria related to water use. (JN)

Describes a soap bubble motor, house insulation models, using hot-water bottles as heat sources, solar mobile, surface tension boat, evaporative cooling experiments, six activities on heat, and a magic trick based on friction. Also discusses using the Cambion Electronics Kit to introduce junior high students to the subject. (JM)

The shore crab (Carcinus maenas) is an excellent subject for school study, both in the field and the laboratory. It is easily collected and maintained and can be used for a wide range of investigations. Some background details are given and possible areas of investigation suggested. (Author)

Provided are activities and demonstrations which can be used to teach infants about the nature of air, uses of air, and objects that fly in the air. The latter include airships, hot-air balloons, kites, parachutes, airplanes, and Hovercraft. (JN)

Presents a method for calculating age specific expectation of life for human populations by examining obituary entries in newspapers, tombstones, and parish records. Examples are given which illustrate large differences between the sexes, social classes, and dates at a given locality. (Author/CS)
