These technical briefs look at agricultural production in many parts of the world, carried out on a small-scale by farmers. Relatively small improvements in agricultural practice can have a big impact on yield and dramatically improve the life of a farmer and their family.

Technical briefs are documents...

Air pollutants arise from natural processes and human activities. In this SATIS Revisited resource, students investigate air pollution, how it is monitored and some effects on human health. Air pollutants arise from a wide variety of sources, although they are mainly a result of the combustion process. It is easy...

This resource uses the context of long distance runner Eliud Kipchoge trying to be the first person to run a marathon under 2 hours, to look at air resistance.  The video below is a good introduction to the challenge facing Eliud. 

The presentation, which contains teacher notes, looks at the forces involved...

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 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...

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:...

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,...

Aimed at both physics students and non-scientists, this book explains Einstein's Special Theory of Relativity pictorially, using diagrams rather than equations. 

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...

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

• Apply correctly the rules for potential difference and current in a parallel circuit.
• Explain the effects of adding a component to a circuit in parallel.           
• ...

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

• Recall the rules for current and potential difference in a series circuit.
• Predict the effect that changing components in a series circuit has on current and potential difference...
