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...

The Nuffield Foundation provides this activity where students suggest types of function to model ozone hole data, before using a graphic calculator or spreadsheet to find at least two particular models. They then consider how well their functions model the data and what they predict for the future. The slideshow...

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...

This excel resource looks at various methods of evaluating pi, including Vièta’s formula and using the trapezium rule.

The first series of sheets include an introduction to François Vièta, his infinite product for...

This optimisation problem is an ideal opportunity to use the real-world context of logistics as an application of first fit, first fit decreasing and full bin algorthims.

In this activity students have to decide how to pack a number of items into the least number of parcels possible, within certain...

This optimisation problem is an ideal opportunity to use the real-world context of logistics as an application of a first fit decreasing algorthim.

In this activity students have to decide how to cut pieces of wood to make a shelving unit using the least number of planks of wood, within certain constraints....

This optimisation problem is an ideal opportunity to use the real-world context of logistics as an application of first fit algorthims.

In this activity students have to allocate a number of different jobs to different employees within certain constraints. As part of the task students are introduced to first...

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...

This Operational Research (OR) Society resource  invites students to analyse processes and efficiencies through a series of group challenges.

In the first activity students are asked to produce as many cups as possible by folding paper. Students are also asked to calculate the mean, variance and standard...

This group task asks students to design, build, evaluate and test paper planes.

The presentation outlines the expected outcomes and also contains teacher notes. It includes a link to a six minute BBC video about the design features involved when making paper planes.

Parabola

This file provides a well illustrated introduction to the properties of a parabola. It begins by illustrating the...

A parabola is given with the x-coordinate of the minimum point, and two points on the parallelogram shown. The points are joined and then a parallel line is drawn that is a...
