This Catalyst article explores gravitational waves which have been observed for the first time, a century after they were first predicted by Albert Einstein.

This article is from Catalyst: Secondary Science Review 2016, Volume 26, Issue 4.

This simulation allows students to visualise the gravitational force that two objects exert on each other. It is possible to change properties of the objects in order to see how that changes the gravitational force between them.

The simulation can be used to:

*Relate gravitational force to the masses...

This is one of a series of extended units, from the Association for Science Education and the Design and Technology Association, to provide in-depth coverage of a topic or an area of the curriculum. This unit was developed by the Centre for Sustainable Energy, which aimed to promote constructive energy education in...

This collection contains a selection of activities including games, quizzes, and experiments, designed to help students of all ages understand the different roles available in green careers using STEM subjects. Highlights include:

• Polar Explorer Careers Booklet - aimed at 7-11 year...

In this video collection, professionals from a variety of careers discuss what they love about their jobs, how they got involved, and what other opportunities are out there.

This collection contains a range of careers case studies from across the STEM subjects. Inspiring individuals talk about their personal journeys and explain more about the exciting careers they have chosen.

This collection provides students with information on the range of careers accessible with a STEM background. Both job-specific and general subject resources are included in this selection.

This collection aims to support teachers in the delivery of career-focussed lessons, particularly looking at green careers and how a STEM background makes positive innovation possible. Resources include both job- and subject-specific information packs, real-life careers case studies, practical experiments, and...

This collection of videos gives students a view into the different types of green careers available. A mixture of case studies and industrial context, this collection covers careers from across the STEM subjects.

This collection of resources help teachers and careers advisers introduce students to the possible career opportunities in emerging green technologies. The activities help to highlight the jobs students can do to help tackle climate change and improve the environment. 

The collection includes a set of case...

Produced by The Centre for Industry Education Collaboration (CIEC), these materials help students understand the underlying principles of electrolysis and how this process is used in the manufacture of chlorine from brine (salt solution). Students see how the technology has developed and changed the efficiency of...

This resources, from Siemens, looks at how an electric car works, the components of the system and the function of each component. Students research the charge and discharge cycles of a battery-powered device and consider the advantages and disadvantages of battery power. They look at what is meant by the capacity...

A Catalyst article about green chemistry. Many reactions take place in solution. Water is a familiar solvent but there are many others, including a rather surprising one, carbon dioxide, which is a non-polluting ‘green’ solvent. The chemical industry relies on solvents to produce many everyday products, such as:...

This information sheet gives educators background information on how the steel making process is changing in order to reduce or eliminate the amount of carbon dioxide produced in the process. It gives details on traditional steel making processes using carbon as the reductant and then discusses alternatives to...
