Diffraction

Practical use of diffraction gratings include emission spectra as well as explorations of the wave-particle nature of light and the interference patterns that emerge.

Diffraction of laser light

In these short videos, Michael de Podesta explains how a laser can be used to show the diffraction and interference of light. Using a laser pen in the classroom, the wave nature of light is demonstrated as a thin wire is used to generate an easily-seen interference pattern.

Two versions of the video are...

Diffusion

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the intrinsic motion of particles and diffusion phenomena...

Diffusion and the Cell Membrane

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

• Use ideas about the needs and life processes of cells to explain the role of the cell membrane and why it must be selectively permeable.

• Recall that substances are...

Dig1t Deals is a card game based on ‘Top Trumps’, where children convert measurements in order to compare metric lengths, weights and capacities.

• Measurements used in the game:
• millimetres, centimetres & metres
• millilitres & litres
• Kilograms & grams

This series provides a close-up view of the human body and how it works. Each book in the series looks at one aspect or function of the body.

The illustrations include full-colour artwork and photographs that use the latest medical techniques. For ages 8 to 12.

A new series which introduces the body to children. Photographs with artwork superimposed show readers how the inside of the body looks and works. Special features on maintaining good health through a balanced diet and exercise, as well as information on issues relevant to each title.

Digestion outlines the...

Carol Bryan uses diagrams and photographs to explain how food is digested in the process of digestion, how digestion works in humans and how digestion works in some animals.

This title explains the process of digestion in both humans and a number of animals. Flaps have been written for parents, teachers or classroom assistants to help children gain a better understanding of the digestive...
