A Catalyst article about why human beings need salt (sodium chloride) in their diets to survive, but too much can be toxic. Where does salt come from, and what is it used for? This article looks at salt extraction and mining in England, the domestic and industrial uses of salt as well as its molecular structure....

This activity allows pupils to learn how to analyse samples on Mars. Students are given the opportunity to use targeted information in areas of astrobiology and geology, to work out what their rovers have found on Mars surface and to think like a geologist as they investigate stratigraphy (layers or rocks) using...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), reporters find out how satellites have revolutionised our understanding of climate change.

They provide a completely different perspective on how planet Earth works, which was impossible before the...

A great deal of space exploration is performed by autonomous craft. They have mapped remote planets and even landed to send surface data back to Earth. Satellites have changed the world of communication, earth observation and, through global positioning systems, everyday navigation. This collection, with...

Traditional cooking stoves burn fuel and produce a lot of smoke which is a major cause of pollution, leading to problems locally for the people using the stoves and also globally as a probable cause of retreating glaciers. According to the World Health Organisation, four million people worldwide die each year from...

This video describes the key differences between vectors and scalars.  It explains that vectors depend upon both magnitude (amount) and direction, whereas scalars are dependent upon magnitude and are independent of direction.

Examples of vector quantities are listed as: displacement, velocity, acceleration,...

This animation, from the Wellcome Trust, illustrates how several species of the Schistosoma parasitic worms exploit humans and fresh water snails. The parasites use rivers and streams to transfer between the two animals, using each for a specific phase of its life cycle...

This document from the Department of Education looks at how St Gregory's Catholic Science College uses weekend detentions to deter behaviour. The resource explores the Saturday detentions and the visibility of senior staff, as part of the managing behaviour and bullying in schools case studies.

Behaviour...

This collection of resources look at many different investigations that can be undertaken with A-level students and covers many required practical pieces of work, alongside other activities which offer alternatives to commonly used work.  Lots build on the work students will have done lower down in school and cover...

This guide, from the National STEM Learning Centre and Network, draws on the advice of a number of experienced senior science technicians on how to set up a technician network. A local science technician network is a great way to share expertise, solve problems, gather ideas and to carry out cost effective...

This collection of science resources is from the evolving Government agencies that have maintained and developed the National Curriculum and associated assessments, tests and examinations, advising the Secretary of State for Education on these matters.
