This simulation demonstrates how Ohm's law relates to a simple circuit. The voltage and resistance can be adjusted to see how this affects the current. The sizes of the symbols in the equation change to match the circuit diagram.

The aim of this investigation is to see the variation of current with applied voltage for two bulbs and compare with Ohm’s Law.  The ones recommended here are a 12V lamp and a small neon bulb.  You can then plot graphs of resistance against voltage to compare the two.

This Catalyst article looks at metals and alloys which play an important role in construction at the Olympic site, both in sports equipment and in medals. Designers must consider the properties of the materials used to make both sports equipment and buildings. These include strength, density, toughness, ductility...

This resource consists of a set of tasks from the Science Assessment Tasks for More Able Students collection, produced by the Centre for Science Education. The tasks have an Olympic-inspired theme and are split into three 'quests'.

Each quest is flexible in use and freestanding in that it can be used either...

This Catalyst article looks at how computer games make increasingly sophisticated use of the laws of physics to produce convincing on-screen effects. From calculating the angle that a ball bounces off a wall to modelling the frictional forces on a rally car, physics has always played a part in the development of...

This book from the Association for Science Education (ASE) covers the history of the discovery of electrons, the underlying science and its applications.The units suggest a variety of activities, including questions, data analysis, reading comprehension and discussion.

In this video, Cathie Wells from the University of Reading talks about how she is helping aircraft conserve fuel which reduces greenhouse gas emissions by making use of high resolution forecasts of three dimensional wind speeds in the atmosphere. In the associated activity, students are asked to calculate the best...

This game invites children to work as a team to build up a sequential model of the Universe in stages, each stage being many times larger in scale than the last. The resource contains copies of the pictures (as PDF files) and detailed teachers' notes. There is a set of...

Work done in this Nuffield 13 - 16 module followed from the S unit called ‘Cars on the move’. This D unit provided enough material for eight double periods during a Further Science course and built on the content of the S units for Single Science. 

The teachers’ guide included 15 worksheets to supplement the...

Palaeontology strives to discover evidence so that we might learn more about the fossil remains of life and understand how they lived, functioned and even died. Scientists at The University of Manchester have been using state-of-the art imaging, chemical analyses and computer modelling techniques to study the...

Mechanical engineer, Tom Hunt, shows how precision machines are used to produce the PanCam instrument, which will be sent to the European Space Agency to be integrated on to the ExoMars rover.  Electronics engineer, Barry Hancock, shows the filter wheel being tested within the labs, at the Mullard Space Science...

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

• Identify a range of circuit diagrams that represent the same parallel circuit.
• Describe how to measure the voltage across the battery and across each branch of a parallel circuit...
