A Life in Brine

Brine shrimps can easily be kept in a jar or aquarium. This article explores some aspects of their lives which are relevant to a GCSE science course.

A Nuclear Future?

About twenty per cent of the UK’s electricity supplies come from nuclear power stations. Many of these power stations are approaching the ends of their working lives. What are the future prospects for nuclear power?

Plants and Soil Nutrients

Plants develop large surface areas both in the air (leaves) and in the soil (root hairs) to get the things they need from the environment. This article explores the relationship between plants and soil and looks at new research on fungi in soil and their involvement with the mineral nutrition of plants.

Oil Refining

Oil supplies from the North Sea and the Middle East are often in the news. This article explores how oil is extracted and refined in another part of the world and looks at the resulting human impact on the environment.
