A Catalyst article examining if there are harmful chemicals in farmed fish. Oily fish such as salmon, tuna, sardines and mackerel contain plenty of protein, vitamins and the right sort of fats. They are rich in omega-3 fatty acids which are released when fats are digested. The human body uses these fatty acids to...

A Catalyst article about the Kepler spacecraft, which is used to look for extra-solar planets. Scientists are hoping to shine light on the age old question of life’s existence elsewhere in the Universe using a new space-based telescope named Kepler. Launched on 6 March 2009, Kepler is searching the sky for small,...

All life forms on Earth are based on organic biochemistry. This activity requires students to analyse an unknown soil sample (just recovered from a space mission to another planet!) and look for signs of possible indicators for life. Curriculum areas covered: • Cell biology • Food tests, including starch, sugar,...

This Science upd8 resource focuses on the chemical PFOA (perflurooctanoic acid), which is used in Teflon manufacture and is reportedly linked with an increase in the risk of developing allergies. In this activity students examine some of the evidence surrounding PFOA and consider a range of viewpoints.

Work done in this Nuffield 13 - 16 module followed from the B unit called ‘What do plants use for food’ and the S unit ‘Food chains and webs’. This X unit provided enough material for eight double periods. It could be selected to complete either a Science or a Further...

Under the Julian calendar which was being used in England at the time Newton was born on Christmas day 1642. However, under the currently used Gregorian calander...

A Catalyst article about scientists publishing their results in journals. Newspapers, magazines and TV programmes are full of stories based on science and technology. But can these articles be trusted? This article looks at the way in which scientists try to ensure that their own publications are reliable. It makes...

This Catalyst article looks at a newspaper report, which carried the headline “It’s life, but not as we know it”, following NASA’s supposed discovery of a ‘second form of life’. The scientific paper, published by the eminent journal Science, even created widespread speculation about the existence of extra-...

A Catalyst article about working in materials science and engineering, the process of deciding which material is best for each application. The structure of materials, processing them and working in jobs and careers with them are explained.

This article is from Catalyst: GCSE Science Review 2007, Volume 17,...

Students explore chicken and human health in relation to microorganisms. To do this, they will learn and use microbiological techniques to examine the microbial load of chicken meat. Then they will carry out a survey into chicken consumption, look at alternative protein sources and explore chicken husbandry at home...

Produced by JIVE (Joint Interventions), this set of information posters are for employers to illustrate how organisations can support and inspire women to enter and progress in Science, Engineering Technology and the Built Environment.

Designed for teachers and STEM Ambassadors, this guide to the James Webb Space Telescope contains sections on the design of the spacecraft and instruments, and the science objects of the mission.  Advice on which information is appropriate for primary and secondary level is included.

Hydrologists are principally involved in monitoring, managing and conserving the Earth's freshwater resources. They study the quantity, trends and implications of freshwater in rivers, lakes, reservoirs, aquifers and glaciers. They also monitor and analyse rainfall. A Levels: Geography, History, Physics
