This simple investigation can be linked to standing waves and builds on work done at GCSE.  In it students look at sending a current through a wire, suspended in a magnet which causes it to oscillate.  From this they can work out the frequency of the mains supply.  They can alter wire length and tension to see if...

In this A-level investigation students can calculate the wavelength of sodium light using a Fresnel Bi-prism. A micrometre eyepiece is required for this but most of the equipment is readily available, and the worksheet provides simple guidance on how to measure this.

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the cause of friction between two objects.

• Explain how friction, generated by the interaction between two objects, can stop them from moving...

This simulation can be used to demonstrate how friction causes a material to heat up and melt. It shows how when two objects are rubbed together they heat up. When one reaches the melting temperature, particles break free as the material melts away. Sample learning objectives include: *Describe a model for friction...

This resource uses pictures for pupils to identify high and low friction forces and classify them into 'useful' and 'not useful' using a sorting grid.  This activity is designed to take place in groups to improve the speaking and listening skills of the learners. This can then be extended by asking pupils to write...

This collection of resources aims to develop an awareness of the types of wildlife found in the UK, in particular amphibians and reptiles. Providing tips on how to identify animals and where to look to find them, they also consider some of the threats these animals face and the things which may be done to help them...

Aimed at primary level, this resource contains seven activity ideas which link to work on animals, living things and their habitats and design and technology. The activities, which contain step by step instructions and photographs, are:

* Making a mini-pond
* Pond dipping
* Making a toad home...

This Catalyst article investigates the research into artificial photosynthetic systems.

With the world’s population ever-expanding, energy demand is expected to double by 2050 and triple by 2100. In only 200 years, mankind has squandered what nature has taken hundreds of millions of years to lay down as...

Produced by the Wellcome Trust Sanger Institute, this animation gives an overview of the process of protein synthesis and how DNA codes for proteins. It covers the major stages of the process starting with where DNA is found in the cell and how its information is transcribed into mRNA. It then follows through the...

This 3D animation shows how proteins are made in the cell from the information in the DNA code.
