This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at how scientists are using fish scales to figure out why the UK salmon population is falling; and how carbon dioxide emissions from power stations could be used to make household bricks.

Salmon numbers...

Produced by the Learning Skills Improvement Service (LSIS), this case study tackles the theme of progression through STEM subjects. By Newham Adult Learning Service, it describes an action research project that aimed to capture progression and learner voice data from a sample of learners who had recently completed...

A Catalyst article looking at how living organisms can act as biological indicators of problems in the way the environment is managed. Skylarks and other birds are disappearing from farmland. The article looks at how the statistics have been obtained, how and why bird numbers have declined and what can be done to...

This Catalyst article introduces Tom Denbigh who describes how he has worked as a volunteer on scientific projects to gain experience before his degree course.

Produced by Rolls-Royce, this series of case studies illustrates the wide range of career opportunities that are opened up for students with skills in science, technology, engineering or mathematics. They can be used to give careers advice and guidance to students as well as to illustrate the curriculum principles...

Produced by Rolls-Royce, this entertaining video clip takes the form of an animated rap which describes a range of career opportunities open to students with skills in science, technology, engineering or mathematics (STEM). It makes a good...

Following the successful rendezvous of the Rosetta spacecraft, with comet 67P, this Catalyst article explains how a smaller spacecraft will land on the surface of the comet. Philae is due to land on the comet on 12 November 2014, the first ever attempt to land an object on the surface of a comet.

This resource looks at life-cycle analysis and how it is used to work out the environmental impact of different products.

This resource can be used as an introductory exercise into mathematical modelling. The problem is to decide on the winning team in a race. Students need to examine the data and decide on a model to determine the winner.

A basketball and a 5kg medicine ball are dropped simultaneously. Which one hits the ground first? It seems obvious that the heavy one should accelerate at a greater rate and therefore land first because the force pulling it down is greater. But this is forgetting inertia - the tendency of mass to resist changes in...
