Could purple tomatoes help us be healthier?

The Citizen Science project was a collaboration between @Bristol's Education team, the University of Bristol, teachers and scientists. Funded by the Wellcome Trust, a series of activities engage both teachers and students in discussions about biomedical science.

This collection contains a range of teacher...

This Catalyst article looks at the discovery of the Arctica Islandica, a mollusc which carries a record of past environments in the banding of its shell. In 2006, scientists collecting material from the seabed off the north coast of Iceland found some clam shells which remarkably were found to have come from...

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...

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 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...

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 explores how high-speed photography can reveal how mosquitoes can keep dry while flying in the rain.

To find out how mosquitoes survive impacts with raindrops, a group of engineers from Georgia Institute of Technology (USA) developed a system which allowed them to photograph collisions...

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

This Catalyst article investigates how plants can be grown in orbiting spacecraft and how this may be useful in future manned space missions.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.

Catalyst is a...

This resource is based around the chemical composition of the human body and the origin of elements in the universe. Students can input a mass in the spreadsheet to see what proportion of their mass is from elements created in the Big Bang, in stars and in supernovae. Graphs are also shown for the relative...

These resources were developed by the Gatsby Science Enhancement Programme and the Centre for Science Education at Sheffield Hallam University in order to demonstrate new ways that ICT can be used to enhance practical work in science. Research scientists use computer technology in both the collection and the...
