A Catalyst article about food additives. Some additives are natural and some are manufactured by the chemical industry. Some, like vitamin C, can come from either natural or artificial sources. As with every other component of food all additives are chemicals. Even organic food can contain a certain number of...

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

This issue of the Big Picture, from the Wellcome Trust, looks at the role that food plays not only in human physiology but also in the individual's lives. Food is about so much more than sustenance. Food choice...

These resources cover themes of food sustainability and security. Included are technical briefs which focus on low cost approaches related to food production and preservation. Technical briefs are documents produced by Practical Action which are freely...

These videos look at how farmers in the developing world grow and transport their food, focusing on the introduction of new technologies.

Gravity goods ropeway in Nepal: A description of how a gravity goods ropeway is used to transport tomatoes down a mountainside.

The everyday context of food serves as a vehicle for engaging learners in exploring the mathematical ideas of ratios, percentages, fractions, and pie charts which are useful in their vocational areas. Students are asked to agree the main food groups that might be suitable for a healthy diet and then represent the...

These technical briefs look at how to store and preserve food in a number of different ways. This is a vital part of food security and enables farmers to provide nutritious food for a longer period to feed their families and to provide an income.

Technical briefs are documents produced by Practical Action...

Like other Nuffield Working with Science units, this topic is intended to give students an opportunity to acquire relevant scientific information, skills, and attitudes, so that they may be able to put all these to practical use.

Students learn and practice how to behave scientifically and to increase their...

What is the perfect curve of a ball’s trajectory, what must the ideal turf be like, and...

This resource suggests a number of investigations into bee behaviour which can be used to:

• develop an understanding of the interdependence of organisms in an ecosystem, including food webs and insect pollinated crops
• consider the importance of insect pollination in human food security

The Forces Sub-Collection is made up of pedagogical guidance and classroom materials for use with students. All materials were published by the Key Stage Three Strategy and the Secondary Strategy between 2002 and 2008.

This series of interactive excel sheets look the forces within strings.

The first sheet shows an adjustable mass hanging on an inextensible string, and demonstrates the fact that the tension is equal to the weight....

This resource, from Mathematics for Engineering Exemplars, shows the application of mathematics within the mechanical and electrical engineering power industry. Here students learn how statistical models are used to set alarms which detect changes in vibration above normal values. The alarms highlight that...
