This collection consists of six field work investigations which relate to the curriculum areas habitats, interdependence and adaptation and the environment. Each survey includes a workbook, field guide and identification guide where appropriate.

The surveys are:

This revised Nuffield Chemistry option began with everyday plastics and sought to demonstrate, measure and explain their properties. Thermoplastics were distinguished from thermosets and the differences explained in terms of the structure and bonding of polymers. A historical section showed how natural materials...

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.

Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use an oscilloscope to measure potential differences that vary with time. The clip shows how to set up the oscilloscope and explains how the vertical displacement corresponds to a potential difference. The...

This resource, provided by the Association for Science Education (ASE), is a pick and mix collection of activities enabling students to create their own stunning scents from scratch. Besides a collection of experiments for making and testing fragrances, there is extension material on applying the particle model to...

Fragrances are full of science, and this activity provided by ASE will enable students to create their own stunning scents from scratch. This resource offers a different way of approaching separating mixtures by linking with other sensory and particle model ideas. Effective use of diagrams, clear explanations and...

Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use a gold-leaf electroscope, zinc plate and an ultraviolet light source. The zinc plate is placed onto the top of the electroscope and it is given a negative charge.

The electroscope can be discharged...

A Biotechnology and Biological Science Research Council (BBSRC) fact sheet and investigation for students aged 10 to 13 which investigates the process of photosysnthesis in plants. The resource describes the process of photosynthesis and the plant structures involved, before showing how photosynthesis can be...

In this practical investigation, students measure the rate of photosynthesis in plants from different habitats (sun and shade), and then consider what this demonstrates about leaf adaptation.

When leaf discs are...
