Alice and Bob in Wonderland are animations produced by the Perimeter Institute for Theoretical Physics. They are based around the questions that Alice has about the physical world and how these can lead to "powerful ideas" in physics, such as energy-mass equivalence and relativity. Topics include time travel, the...

Produced by the Royal Observatory Greenwich, this booklet gives instructions on a practical demonstration of the Doppler effect. The practical uses a portable speaker an audio software to calculate the change in frequency. Included is an online video that shows the demonstration and places it in the context of...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at invasive species of plants and animals. Many of them are well-known. Grey squirrels, harlequin ladybirds, buddleia, Japanese knotweed - the list goes on. Some of these aliens, or invasive species to give them...

Alison Foster has combined her education in Chemistry with her love of plants to engage in some exciting projects at the University of Oxford Botanic Gardens. This Catalyst article gives a profile of her career choices, and introduces a public engagement activity called Chemistry in the Garden.

Alison began...

This Catalyst article investigates materials used in jet engines. They must withstand high temperatures and great forces. Special alloys are used for structures such as turbine blades. The article is from Catalyst:...

Alternatives for Science Education was produced and published by the Association for Science Education (ASE) in 1979. Its sub-title, A Consultative Document, indicates its aim and status. In addition to being a document of considerable historical interest, it contains arguments of continued relevance.

The...

A Catalyst article about aluminium, a shiny silvery metal, which is extracted from its ore by electrolysis. Further addition of other metallic elements results in an alloy, which can be cast into various shapes using moulds. The article looks at the processes of extraction, casting, patterns, moulds and finishing...

The resource pack is produced by The Centre for Industry Education Collaboration (CIEC). It looks at the life-cycle and environmental impact of aluminium products.

Student activities and investigations help to illustrate curriculum science in real-life contexts. This includes:
* Constructing a cradle...

In separate documents, this resource provides guidance for teachers to plan for progression of students aged 11-16, based on the National Strategies Framework for Secondary Science Learning Objectives. Each learning objective is given further explanation under the heading ‘Pupils could learn to … ’

This Catalyst article describes an experiment with fluoride toothpaste on eggshells (as a substitute for teeth). Both teeth and eggs contain calcium compounds which can be attacked by acid. When an egg is put in vinegar the shell is weakened by the acid making it soft and more fragile. When teeth are exposed to...

Produced by the Learning and Skills Improvement Service, these materials introduce students to circuit symbols. They develop their knowledge and understanding of circuit symbols and components through a range of short, interactive learning activities. These are particularly useful to reinforce, or consolidate,...

This report, published by the Nuffield Foundation in July 2009, examines the major issues of policy and practice surrounding applied science qualifications, taking account of empirical evidence where it is available. The report is centred on the following questions:

• what is distinctive about applied...

This video provides an introduction to waves which looks at the differences between types of wave.  It would make a good revision video which discusses mechanical and electromagnetic waves with examples of each, with how particles and fields fit into the topic.  They presenter also demonstrates the difference...
