This video demonstrates how a 19kg flywheel, attached to a 1 metre shaft can be lifted easily when the flywheel is spinning, yet almost impossible when stationary. It appears that the rotation reduces the weight of the...

This Catalyst article describes how bacterial colonies produce antibiotics and explains how their growth depends on the medium they grow on. Over sixty years ago, a Russian soil scientist called Selman Waksman discovered that soil bacteria belonging to the Streptomyces genus produce some very useful...

Produced by Science & Plants for Schools (SAPS), this resource encourages students to investigate the effects of various antifungal treatments on the growth of yeast.

This poster looks at the nature of antimatter. One side of the poster discusses Dirac’s prediction and the subsequent discovery of antimatter, in the form of the positron. The difficulty of the storage of antimatter is explained and the use of positrons in medical imaging (PET scanners) is described. The other side...

This article discovers how geneticists are beginning to discover the significance of junk DNA. The article is from Catalyst: Secondary Science Review 2015, Volume 25, Issue 4.

Catalyst is a science magazine for students aged 14-19 years. Annual...

The project involved members of staff from the STEM subjects at the Kingswinford School working collaboratively to plan and deliver sessions to a group of Year Nine students. These sessions were held after school for an hour each week during the summer and autumn terms...

This set of ten video case studies, from around 2010, illustrate a range of technician roles that use science and mathematics. The examples feature young college students and apprentices who talk about their area of study or work and who have a clear career route in mind. 

The case studies cover:

In this podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection, Richard Hollingham reports from an unusual and somewhat cold location - onboard the British Antarctic Survey's RRS James Clark Ross which was stuck in the ice for two weeks 1000 kilometres from the North Pole. He...

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). As the map of Earth's gravity – as revealed by the European Space Agency's (ESA) sleek GOCE satellite – comes into sharper focus, Richard Hollingham speaks to a researcher who tells us what early results from the...
