A Catalyst article about the naming system used for biological species, devised by Linnaeus. The purpose of biological names is investigated and the article also explains how the naming system works.

This article is from Catalyst: Secondary Science Review 2009, Volume 19, Issue 3.

Produced by the Royal Observatory Greenwich, this booklet introduces the concepts of dark matter and dark energy. Included is an online video that discusses how the Universe will end, including the role of dark matter and energy. The booklet describes the composition of the Universe, this is followed by questions...

The aim of this investigation is to find the value of a number of resistors using a Wheatstone bridge.  Although this is an historical piece of equipment that has been superseded by modern methods it provides an excellent way to understand potential difference in circuits.

Sports engineers from Sheffield Hallam University and Frazer Nash are helping Team GB's wheelchair paralympians fine-tune their equipment and training regimes using advanced analysis technology. Engineers explain the relationship between science and engineering in disability sports and how inspiring it is to work...

This Catalyst article looks at agricultural plants, that are prone to many diseases, and scientists who develop new techniques to fight these diseases.

The video asks students to predict when a bungee jumper experiences maximum acceleration.  The answer is at the very bottom of the jump.  This is often counter-intuitive as the velocity at this point is almost zero. 

However, acceleration is the rate of change of velocity over time, a = ^Δv/_Δt...

This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

This Catalyst article explains why there are many anti-bacterial drugs but few antivirals. There are millions of bacteria everywhere – on skin, in the gut, and on food. Bacteria have been troubling human beings for as long as they have been around, so a lot of effort has been directed into finding ways to fight...

Produced by the Royal Observatory Greenwich, this booklet guides students to use Einstein’s mass-energy equivalence equation to determine when the Sun will become a red giant. Included is an online video that discusses how we can determine how old the Sun is. Details on the relationship between mass and energy in...

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...
