This challenge enables pupils to model and test filters as a way of making dirty water cleaner. It can also be used to explore ways of making water safe to drink.  Curriculum links include separation techniques and pure substances.

The challenge can provide a focus for National Science and Engineering Week,...

This resource from Farming & Countryside Education (FACE) allows students to investigate how different farmers have addressed the challenge of sustainability, and the solutions they have devised to remain in business despite the serious long-term problems faced by the sector. The farm profiles help the students...

This Catalyst article explores how many mammal species' bodies are adapted to cope with the great pressures involved as they dive to great depths.

A Catalyst article about people who believe that their health is affected by mobile phone radiation. The World Health Organisation has labelled this condition Idiopathic Environmental Intolerance with attribution to Electromagnetic Fields (IEI-EMF). Idiopathic describes a disease with no known cause. The article...

This set of twelve colourful postcards provides hands on activities which link to the topics of electricity, sound, forces, and changes of state. Ideal for use in the classroom, the mini-investigations are fun to do and get children thinking about the concepts involved. They are also perfect for use in after school...

This series of Marvin and Milo cards have been pulled together for the International Year of Light 2015. They include eight simple experiments that can be performed at home that link in to the theme of light, using: - A torch and a bottle to show total internal reflection - A glass of water to make a lens - Milk...

A Catalyst article about mobile phones. This article looks at the science behind this popular piece of technology, such as the use of radio waves, aerials and cells. The article also explains how mobile phones are able to use short aerials.

This article is from Catalyst: GCSE Science Review 2005, Volume 16,...

Produced by the Science Museum, this resource sees students working in groups to explore the issues surrounding genetic testing. Students receive a sealed secret box, that contains a chance card. Opening the box represents taking a genetic test. Students have to decide whether they would want to open the box. In...

This video asks people if they believe cell phones can cause cancer.  It then considers the available evidence logically, that is types of radiation emitted by a cell phone (non-ionising) and the power rating to conclude that the radiation should not be harmful. However, recent evidence suggests that heat-shock...

This resource provides a set of videos and a practical investigation aimed at supporting working scientifically in the classroom and relating science to real world experiences. In the first video Professor Brian Cox joins a teacher to find out how to set up and run an investigation to find out if plants need soil...

A PISA in Focus study published in 2012 from the OECD (Organisation for Economic Co-operation and Development), looks at whether students perform better in science if they are encouraged to participate in extracurricular activities, such as field trips and science projects. Most countries (22 of 31 OECD countries)...

Video from the Big Picture issue on Fat, showing an experiment to discover if we favour fatty foods.

The oceans are become more acidic. This is due to an increase in carbon dioxide in the atmosphere through the ...
