This booklet contains a number of very briefly described algorithms, which students are then expected to analyse, develop an algorithm for and then implement in a language of their choice. Each section contains success descriptors at three different levels which could be adapted to meet the requirements of an...

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...

This puzzle contains five pieces of information about people shaking hands at a party. The task is to establish the number of people at the party and determine who shook whose hand.

Alien Invasion is a set of four interactive lessons about a full-scale alien attack that coincides with a class visit to Manford City. To set the scene and support the lessons, live television news bulletins, radio broadcasts and telephone messages help to develop the story line. The invasion leads to a series of...

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...

These activities, from Eurostemcell, introduce students to the science of stem cells and explore four basic themes in stem cell biology: 1. What is a stem cell? – what stem cells can do; types of stem cell 2. Where do embryonic stem cells come from? – the blastocyst; cell culture; IVF 3. Why bother with stem cells...

This activity introduces pupils to algorithms and gives them the opportunity to create and debug simple programmes using bee-bots. Throughout the three activities pupils will be taught that algorithms are clear step-by-step instructions before programming a bee-bot to follow their own inventive algorithms to reach...

This physics extension module from the Salters' Science course deals with binary digital electronic devices, taking a systems approach. Ideas of input, output and control are considered and the concept of feedback. The use of logic gates to control switches and latches...

In this project, students investigate and compare the waterproof and breathability properties of a range of fabrics used in clothing designed for sailing. They will find out about the different fabrics used in wet weather sailing gear. In particular, how breathable waterproofs work and what advantages and...

This resource explores how there can sometimes be conflict between people and animals in some habitats and how the World Land Trust's conservation partners work to protect local people as well as animals such as Indian elephants and Bengal tigers. Pupils are encouraged to think about what they might do to support...
