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 Revised Nuffield Option aimed to help students see their experience of elements and compounds in a more unified and coherent theoretical framework. The treatment was based on experiment but emphasised theory.

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). With efforts to improve energy efficiency focused on green transport, sustainable power generation, growing your own food and reducing waste, it is often easy to forget that the very buildings we live and work in...

This Catalyst article explains how orchids have evolved over millions of years to have a close relationship with the insects which pollinate them. Like many plants, orchids rely on insects to carry pollen from one flower to another in order to reproduce. Many plants offer a reward to pollinators, and so do some...

This Nuffield 13 - 16 module is one for the start of the three-year programme. This B unit provided enough material for six double periods in the third year of secondary school (year nine). The teachers’ guide included four worksheets to supplement the students’ booklet...

Produced by the Wellcome Trust Sanger Institute, this practical activity allows students to create an origami model of DNA, demonstrating its double helix structure. The activity provides a hands-on way of learning about the structure of DNA.

Two templates are available as PDFs; a standard template with the...

This activity is designed as a ‘virtual mission’. Students will play the part of Near Earth Asteroid (NEA) scientists to the scenario of a possible asteroid impact with the Earth. By following the story of the mission (led by an automated powerpoint), students will apply their understanding of kinetic energy,...

This booklet is unusual in this series as it develops one theme, genetic inheritance, to show the use of...
