This experiment provides a quick and eye-catching way to teach about the vascular tissue in plants and the structure of plant stems. It provides students with the opportunity to develop (and demonstrate) their scientific drawing skills as well as their use of a light microscope and eye-piece graticule.

This updated version of the SAPS algal balls resource is designed to support the use of practicals across 2015 A-level biology specifications.

Students measure the rate of photosynthesis in comparison to the rate of respiration. Because of this, it is possible to determine the light intensity at which the...

This Nuffield Working with Science unit was designed to enable students to investigate the sources, nature and impacts of air pollution.

Guidance for teachers and technicians appears in...

This Nuffield Working with Science unit aimed to give students the experience of designing experiments, carrying them out, and evaluating the results. The unit explores the paranormal which is a field where there are many strongly held beliefs, often unsupported by...

This Nuffield Working with Science unit aimed to draw on the popularity of bird watching to develop skills of observation and investigation.

Guidance for teachers and technicians appears in...

The core of this Nuffield Working with Science unit is made up of sections covering the preparation and testing of beer, the science of brewing, and the effects of alcohol consumption.

Guidance for teachers and...

This Nuffield Working with Science unit was intended to help students to appreciate the purposes of different types of cosmetics, to distinguish between purely decorative and 'useful' preparations, to understand the reasons for the formulations of different types of...

This Nuffield Working with Science unit featured experiments derived from forensic techniques but could only give the 'flavour' of a scientific investigation of a crime. The unit aimed to emphasise the basic needs, in a scientific investigation of evidence, of accurate...

The work suggested in this Nuffield Working with Science unit encourages the students to start thinking about efficiency by presenting them with some problems which are a familiar part of their daily lives. They are asked to investigate problems which have been chosen...

This Nuffield Working with Science unit aimed to enable students to design circuits to meet specific needs. The plan was also to help students to realise the range of electronics problems which they can solve by taking a systems approach.

This series of activities, from the Institute of Physics, help student to understand electrical resistance. What is resistance, how it can be measured, how it arises and what affects it? During the topic, resistance is related to current, voltage, type of material, temperature and light intensity. The electrical...

In this learning episode, from the Institute of Physics, students derive the equation relating electromotive force (emf), terminal potential difference, current and internal resistance. They then tackle questions about the internal resistance of a power supply.
