This video models refraction using a vehicle travelling from a concrete surface to a grass surface and shows how the forward wheel slows and so the vehicle changes direction.

A diagram is then constructed to develop Snell’s law, i.e., the angle of incidence (from air) is proportional to the angle of...

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

• Recognise that as a transverse wave travels forward, the medium through which it travels does not.
• Describe the movement of each ‘particle’ of a transverse wave as the wave moves...

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

• Identify the shadow made by an object

• Describe how light travels in straight lines

• Explain how shadows are formed

• Explain how light...

A Catalyst article about a brilliant new light source under construction in the heart of the Oxfordshire countryside - the Diamond Light Source. Diamond will be a source of synchrotron light. Many of the everyday commodities people take for granted, from chocolate to cosmetics, from revolutionary drugs to surgical...

Inspired by the theme of the Victorians, this activity supports the teaching of design and technology in context by looking at the key events that defined the Victorian era, and how they have influenced engineering developments and society today.

In this classroom activity learners will learn about the...

This resource provided by Siemens contains three lessons which link to various aspects of energy production and electricity. The lessons are:

• The magic of making electricity - Pupils find out how electricity can be produced and used. They look at examples of hand crank technology and...

From the Institute of Physics, this resource provides extensive teacher guidance and suggested classroom activities to support the teaching of:

* Seeing with light
* Modelling light with ray diagrams
* Reflection and refraction
* Colours of two kinds

Each topic is explored from the...

In this activity, students see how the primary colours of light turn white when mixed together. There is a brief description of the visible spectrum and how animals can see UV light, with some questions for students to answer.
