A Catalyst article about the Kepler spacecraft, which is used to look for extra-solar planets. Scientists are hoping to shine light on the age old question of life’s existence elsewhere in the Universe using a new space-based telescope named Kepler. Launched on 6 March 2009, Kepler is searching the sky for small,...

All life forms on Earth are based on organic biochemistry. This activity requires students to analyse an unknown soil sample (just recovered from a space mission to another planet!) and look for signs of possible indicators for life. Curriculum areas covered:

• Cell biology
• Food tests, including...

This set of activities for students builds toward them being able to answer the question 'Assess whether the UK is becoming more extreme in the 21st century.'  Initially students are asked to define the terms 'rare' and 'extreme' and then order the layers of the Earth's atmosphere. This is followed by tasks to:...

This report identified the alarming disparity between the proportions of students studying mathematics beyond the age of 16.  At that time only one-fifth of pupils in England continued to study maths at any level after achieving a GCSE - the lowest of 24 developed countries. A key recommendation from the report was...

This video explains why astronauts float. The common misconception is that there is no gravity in space, yet the astronaut is in the Earth’s gravitational field.  Rather, the astronaut is falling towards the Earth (as is the spacecraft). However, their horizontal speed is 28,000km/hr. This and the curvature of the...

The aim of this activity is to encourage discussion about the nature of relationships between variables. It provides examples of relationships where there may appear to be correlation but not necessarily a causal relationship. The task is suitable for group or...

Newton is regarded as one of the most influential physicists and mathematicians of all time and his actual birthday depends upon which calendar is used. Under the Julian calendar which was being used in England at the time Newton was born on Christmas day 1642. However, under the currently used Gregorian calander...

This Unilever Laboratory Experiment, published in 1966, describes the use of steam distillation to separate oil from crushed cloves. The method for extracting the eugenol from the oil used carbon tetrachloride (tetrachloromethane) and so would need to be modified before this could now be done in schools and...

A resource from the National Centre for Excellence in the Teaching of Mathematics (NCETM) online FE magazine which is aimed at educators interested in or teaching in the further education sector or post-16 education generally.

Odd one out, is an activity that aims to promote discussion and observation,...

This resource from the further education edition of the National Centre for Excellence in the Teaching of Mathematics (NCETM) online magazine, explores how photographs could be used in lessons as starting points for mathematical discussion or exploration.

Using the context of digital devices, this article from the National Centre for Excellence in the Teaching of Mathematics (NCETM) FE online magazine, explores how students might be helped to understand how decimal numbers work by considering binary numbers and manipulating them. Tables are used to explain the link...

A Catalyst article about scientists publishing their results in journals. Newspapers, magazines and TV programmes are full of stories based on science and technology. But can these articles be trusted? This article looks at the way in which scientists try to ensure that their own publications are reliable. It makes...

This report from the Institute of Physics explores data from the National Pupil Database, looking at progression to A level physics from Key Stage Four in different types of school. In particular, it focuses on the inequalities of numbers between the girls and boys taking the subject at this level. Although girls...

This Catalyst article looks at a newspaper report, which carried the headline “It’s life, but not as we know it”, following NASA’s supposed discovery of a ‘second form of life’. The scientific paper, published by the eminent journal Science, even created widespread speculation about the existence of extra-...

A Catalyst article about working in materials science and engineering, the process of deciding which material is best for each application. The structure of materials, processing them and working in jobs and careers with them are explained.

This article is from Catalyst: GCSE Science Review 2007, Volume 17,...
