A series of images representing double helix images.

• DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

A Catalyst article about Charles Darwin's home and in particular his study which is open to the public. Visiting information is included in the article which puts into context the importance of this room in his work.

This Catalyst article looks at how people lived in the past, archaeologists look at the items (artefacts) these cultures left behind. Using chemical analysis of residues in the artefacts an enormous amount of additional information can be gleaned. This article investigates early dairy farming. Analysis of tiny...

From the Microbiology Society, this resource contains information about biofilms. These are communities of microbial cells attached to a surface. For example, the slime lining plugholes and drains or the rough deposit that can coat teeth at the end of the day. The information clearly describes: * What are biofilms...

Computer modellers use computers to help them understand how the world works and to help predict what might happen in the future. Sea ice modellers use computer software to simulate how ice freezes, melts and moves and how different things such as ocean temperature affect it. A Levels: Maths, Further Maths, Biology...

A Catalyst article about the working life of Dr Gillian Lockwood, a reproductive biologist who specialises in IVF. The article looks at the ethical issues surrounding fertility treatments for problems such as polycystic ovary syndrome.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue...

This Pedagogics resource displays a quote from Dr Haim Ginott entitled "I have come to a frightening conclusion".

Marine biologists study organisms in the world's oceans, ranging in size and complexity from viruses to whales. They examine how these organisms interact with the environment and with each other and measure the effects of human activities and environmental changes on marine ecosystems. A Levels: Biology, Maths,...

This article introduces Laura Waters, who is a chemist at Huddersfield University with an interest in both doing scientific research and communicating her work to a wide audience.

The article is from Catalyst: Secondary Science Review 2015, Volume 25, Issue 4.

Microbiologists study microorganisms including bacteria, viruses, fungi, algae and protozoa. They are involved in many areas of work, including pharmaceuticals, cosmetics, water and agriculture. A Levels: Biology, Maths, Chemistry

Geosciences, or geology, are the scientific study of the structure, evolution and dynamics of the earth and its natural resources. A Levels: Biology, Geology, Chemistry

A Volcanologist studies the impact of volcanoes on the atmosphere and our planet as a whole. Volcanologists often work to try to understand how to better predict eruptions and minimise the effects on people arising from them. They may use computer modelling or satellite imagery and often work on or around volcanoes...
