A Catalyst article about oxygen and how it is essential for most respiration, which goes on all the time in all live cells all living organisms. The article looks at how organisms get the oxygen they need from their surroundings and how it reaches cells. It also explores how oxygen transport is monitored, which of...

A multiple choice quiz on the ozone layer AS/A level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

Produced by Becta, these case studies illustrate how information communication technology (ICT) can be used to enhance teaching and learning in science. This case study looks at use of PDAs during an A-level biology field study.

PDAs, also called 'handhelds' or 'palmtop PCs', are relatively cheap and robust...

The Teaching Primary Science book Paints and materials draws upon some of the materials and techniques of artistic expression to explore ways of asking questions and finding answers in a scientific way. Each chapter contains an activity and a list of materials for...

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...

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). Does your shopping basket contain chocolate, biscuits and shampoo? If it does, you may be unwittingly contributing to the destruction of the some of the world's pristine rainforests.

Manufacturers now use...

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...

This activity has been designed to help pupils understand the different applications of satellites in the field of Earth observation. Scientists use the data collected by these satellites to monitor changes in environments across the planet.

There are three satellites that pupils can build:

• ...

Pupils will learn about materials and forces, including gravity and air resistance, in this experiment from the IET. Using Christmas as an opportunity to get practical, p...

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...

In this A-level investigation you will look at the factors that affect the properties of a parallel plate capacitor.  You can alter the area of overlap or the spacing’s between the plates to see how this impacts on the results.

These animations, from the Wellcome Trust, help to show how parasitic worms are a major public health problem.

Thriving in numerous parts of the world associated with poor sanitation or water, these parasites have devised ingenious mechanisms that allow them to enter the human body, resulting in serious...
