This video demonstrates how the gravitational potential energy of a skateboarder is converted into kinetic energy as they move down a ramp.  It discusses efficiency and how you can calculate the energy mathematically at both stages.  It also ties into SUVAT and demonstrates how an objects acceleration due to...

These technical briefs look at the ways Practical Action have helped poor communities to make the best use of their own labour and to use locally produced building materials and techniques that they can afford and manage.

Technical briefs are documents produced by Practical Action which are freely available...

These resources were originally developed to support post 16 Applied Science specifications, and include:

This resource from Wellcome Trust Sanger Institute is a hands-on classroom activity for Key Stage Two students that aims to support the teaching of topics such as microbes and hand hygiene. This interactive, practical activity demonstrates how microbes, such as bacteria and viruses, can be spread through surface...

This STEMNET resource describes the background and career of STEM Ambassador Vicki Hodges, an Attitude and Orbit Control Systems engineer working on a project to develop an unmanned spacecraft.

Having joined the Astrium graduate scheme, Vicki has moved around the company and gained experience in a variety of...

This is one of a series of focused units, from the Association for Science Education and the Design and Technology Association, to introduce students to important technologies and their applications. This unit features control systems and their applications to...

These activities, produced by The Centre for Industry Education Collaboration (CIEC), are based on a BASF chemical plant at Seal Sands, Middlesbrough. They enable students to see how and why chemical reactions are controlled in a chemical plant. The materials contain full teacher guidance, student notes and...

The enzyme lactase is widely used in the dairy industry to convert the naturally occurring disaccharide sugar lactose into glucose and galactose. In this practical students investigate the treatment of milk with lactase. Following treatment they test the glucose content of the converted milk, and compare products...

A Catalyst article looking at the use of gas and electric for cooking. The article focuses on the latest hobs which use radiant, halogen or induction electric heating, to see if they can compete with gas.

This article is from Catalyst: GCSE Science Review 2004, Volume 14, Issue 3.

Comets are considered to be time capsules containing information about the conditions of the early Solar System. In order to understand what comets are, where they come from, and their influence on the evolution of Earth, it is necessary to find out what material they contain. This teacher demonstration and student...

A case study produced by the Engineering and Physical Sciences Research Council (EPSRC) which looks at an affordable cooking stove that generates electricity and could transform lives in the world’s poorest communities. It burns biomass such as wood or dung and converts the heat produced into electricity. Over two...

A Catalyst article about the work of a scientist from the British Antarctic Survey, gathering data about climate change by studying ice cores from Antarctica. One of the areas of research was to find out whether it is possible to learn how much sea ice there was around Antarctica in the past by measuring how much...

A Catalyst article explaining how scientists have found that the overturning circulation in the Atlantic Ocean, which maintains Europe’s moderate climate, was weaker in 2004 by 30% relative to earlier estimates. What does this mean and what impact could it have on our climate? Scientists' research and their climate...
