Developed by the Centre for Science Education and supported by the Astra Zeneca Teaching Trust, the Double and Triple Crossed projects aimed to bring science and history together to increase engagement in science through topic based, contextualised learning.

The project enabled thirteen science and history...

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

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...

This resource aimed at 9-11 year olds, provides a video showing  Edward Jenner's work on developing a vaccine for smallpox over 200 years ago. A follow-up activity explores how modern-day scientists make sure a new vaccine works and is safe. Children use what they have learned to...

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 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,...
