With this a-level video tutorial, the presenter talks about how we get the equation speed = distance / time and then looks at the differences between a distance / time and a speed / time graph.  It also demonstrates what the area under the graph represents as well as the gradient.  This can be followed by the...

A person is shown spinning around on a playground ‘carousel’ before getting off and walking away. The task is to graph the distance of the person from the centre of the carousel against time. Whilst the person is spinning on the carousel the resulting graph shows that distance is constant. This story can be used as...

A person is shown exercising using weights whilst lying on a bench.  As the weight is lifted the arms of the person curl around, so that the distance from the bench is not linear with time. As the exercise progresses it takes longer to do each bench press. Finally the weights are placed back on the resting stand....

A person is shown spinning around on a playground ‘carousel’ before getting off and walking away. The task is to graph the distance of the person from the camera against time. The resulting graph has periodicity and non-linear elements. This story can be used as a complement to ‘Distance from centre of carousel’...

A player is shown on a baseball pitch. They run around the bases before returning to the home plate. The speed varies between the different bases. The task is to draw a graph of the player’s distance from the home plate against time. The graph shows linear piecewise sections.

Distance from the home...

Produced by the Learning and Skills Improvement Service, this activity takes students through a step-by-step approach to understanding the basic principles of distance-time and velocity-time graphs. Working through the activity will help students to:
* Understand the terms distance, time, velocity and...

This resource from Farming & Countryside Education (FACE) allows students to investigate how different farmers have addressed the challenge of sustainability, and the solutions they have devised to remain in business despite the serious long-term problems faced by the sector. The farm profiles help the students...

This resource, from the Centre for Innovation in Mathematics Teaching, uses diagrams to illustrate division by a fraction and, to clarify the common misconception identified with this task, prompts students to rethink the statement, divide three by one quarter, as the number of quarters that fit into three....

This Catalyst article explores how many mammal species' bodies are adapted to cope with the great pressures involved as they dive to great depths.

A Catalyst article about people who believe that their health is affected by mobile phone radiation. The World Health Organisation has labelled this condition Idiopathic Environmental Intolerance with attribution to Electromagnetic Fields (IEI-EMF). Idiopathic describes a disease with no known cause. The article...

This Economic and Social Research Council (ESRC) school briefing looks at the effectiveness of advertising and whether it really is necessary for advertisers to use very thin models to sell their products. Counter to this view, research shows that women are just as likely to buy a product if the model is of average...

This series of Marvin and Milo cards include eight simple experiments that can be performed at home that link in to the theme of light, using: - A torch and a bottle to show total internal reflection - A glass of water to make a lens - Milk and water to show the scattering of light - Making a light bulb light up...

A Catalyst article about mobile phones. This article looks at the science behind this popular piece of technology, such as the use of radio waves, aerials and cells. The article also explains how mobile phones are able to use short aerials.
