The videos in this collection from teachers TV are aimed at secondary school science practitioners. They contain materials that can be used in the classroom, as stimulus material.

Clips in this section cover a wide range of topics, including:
* astronomy, space and the solar system
* Earth...

Professor Sanjeev Gupta explains how scientists from many different disciplines have been brought together for the European Space Agency Aurora programme.  Scientists and engineers also speak about how exciting it is to be working on a search for life on other planets. 

This video is part of a series of ten...

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...

This Catalyst article looks at how scientists can use material recovered from archaeological sites to see how crops have been introduced to different countries over the history of farming. Three processes by which some plant material can be preserved are explained. The ratio of carbon isotopes from the collagen in...

This Catalyst article looks at salt, in particular the process of extracting salt from the sea in the salt factories of Trapani in Sicily. Located on the west coast of the island, the saline (salt ponds) were probably started by the Phoenicians around 3000 years ago. The article also looks at the structure of salt...

This Catalyst article looks at NASA's Mars Curiosity rover, the automated chemistry lab which landed safely on Mars in August 2012. Capable of analysing samples from the planet's surface and atmosphere, the rover will undertake two years of experiments in the hope of discovering even more about our neighbouring...

This pack has all you need to facilitate a structured debate on the controversial topic of whether the town centre ought to be for self-driven cars only. The structure shows students how to build a discussion and back up their opinions with facts. The pack provides outline guidance for four imagined but...

This Catalyst article looks at how the structure and properties of chocolate change when it is melted and re-solidified. An experiment is described in which the differences between solid chocolate, and chocolate which has been melted and re-hardened can be found, along with a detailed explanation of the physics...

Nathan is an environmental improvement manager at North East Lincolnshire County Council.  He looks at the impact of the council on climate change and what they can do to reduce that impact across the full range of council services.  He’s essentially an ‘eco-warrior’ for the council.

Curriculum links include...

David works for the Scottish Parliament as an environmental manager. He is responsible for trying to understand the environmental impact of the parliament, such as the amount of energy it uses.  The parliament has set itself challenging targets to reduce the amount of gas and electricity it uses through initiatives...

These materials provide examples of effective practice in equality and diversity within STEM subjects and careers. 

The non-statutory guidance containing information on what schools need to do to meet their requirements under the equality duties can be found...

The ‘Experimenting with Industry’ series was published in the mid-1980s when it presented industry-related science practicals for schools. It was developed as part of a 'teachers into industry' project organised by The Association for Science Education (ASE) on behalf...

This Catalyst article looks at life in extreme environments on Earth which can suggest how life might exist on Mars. One of the developments in recent years that really opened up scientists’ eyes to the possibility of life on Mars has been the realization of just how adaptable and versatile life on Earth is.

What is the perfect curve of a ball’s trajectory, what must the ideal turf be like, and...
