In this lesson students learn about the physical, chemical and bacterial contamination of food at different stages of processing and production. They also learn about positive micro bacterial changes, such as in the production of yoghurt and some cheeses, and the conditions in which micro-organisms survive and...

This Science upd8 resource focuses on the chemical PFOA (perflurooctanoic acid), which is used in Teflon manufacture and is reportedly linked with an increase in the risk of developing allergies. In this activity students examine some of the evidence surrounding PFOA and consider a range of viewpoints.

In this Revised Nuffield Chemistry option, ideas about proton and electron transfer were used to explain the decay of stonework and the corrosion of metals. Practical investigations explored the physical and chemical changes that can lead to the breakdown of stone as well as the factors that determine the rate of...

This set of careers posters introduce science apprenticeships, highlighting that students can gain qualifications such as degrees whilst working for top chemical, pharmaceutical and health science companies and being paid. Each poster has the same...

This Science upd8 activity focuses on sulphur, which is usually the element fingered for the blame when it comes to pollution. Students research sulphur to get the low down on this "Jekyll and Hyde" chemical; then act out a trial of the suspect element.

These resources are provided by the Nuffield Foundation who, in 2007, commissioned a team from the University of Oxford to review the available research literature on how children learn mathematics. The resulting review is presented in a series of eight papers.

Paper 1 Overview - summarises...

A Catalyst article looking at the chemicals that are in plants and trees and the role they play in the life of the plant. Starting with photosynthesis the article moves onto naturally occurring chemicals and explains why plants need fertilisers. Growing salad crops hydroponically is also examined.

Using this resource, from Defence Dynamics, students work as the Operations Team for a Royal Air Force (RAF) squadron on Quick Reaction Alert (QRA).

Presented with a series of imaginary scenarios, students have to review and plan routes for a number of aircraft facing different crises.

The lesson aims...

This is a worksheet which looks at various factors which effect the scaling up of laboratory processes to industrial scale in the commercial manufacture of dyes.  Students look at

• costs of the raw materials for each dye 
• the percentage yield 
• size of reaction vessels  
• energy...

This booklet contains a range of suggested activities and contexts for teaching kinetics A level. Curriculum links include catalysis, activation energy, activation enthalpy, enthalpy profile, enzymes, rates, Boltzmann, Arrhenius, rate equations, half-life and reaction mechanisms.

Although produced to support...

In this activity, produced by Gatsby Science Enhancement Programme, students are presented with a range of graphical information.

Students are presented with a graph about atmospheric oxygen levels at different altitudes. They are asked questions about the graph and also pose questions to their fellow...

Towards the end of the Revised Nuffield Advanced Chemistry course, students made a four week study of a science that was based on chemical principles. The principal purpose of this section of the course was to enable students to see something of the scope of a related subject, and to appreciate its dependence upon...

As in the previous editions, students of the Fourth Edition of Nuffield Advanced Chemistry were required to undertake a four-week study of an applied aspect of science which was based on chemical principles. The main purpose of this section of the course was to help students to see something of the scope of a...
