Mars Express

A Catalyst article about the idea of life on Mars. Scientists involved with the Mars Express mission aim to find out more and will try to establish if there ever has been life on Mars. The article looks at the miniature devices that they will employ on the mission. 

This article is from Catalyst: GCSE...

Marble-ous Ellipses

In order to understand the orbits of planets, comets and other celestial bodies, it is necessary to examine the principles of how gravity, and the velocity of an object, interact to produce an orbit. It is a common misconception among students that planetary orbits are circular. This practical activity gives a...

Magnetic Math

This series of activities from NASA take a mathematical approach to looking at magnetism. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 14 to 19 years.

The problems were created to be authentic glimpses of modern...

Lunar Exploration

Produced by the Royal Astronomical Society, this information booklet looks at how our knowledge of the Moon has been built up through observation, unmanned exploration and the lunar landings of the Apollo missions. Sections include: * Experiments on the Moon * Moon rocks * Structures on the lunar surface * Beneath...

Living in Space

Produced by FootageVault, these videos from NASA illustrate the effects of apparent weightlessness as astronauts live and work in space. Clips include astronauts in Skylab, the Space Shuttle and the International Space Station. The clips can be used to illustrate forces, movement and how objects behave in...

Little Green Men

This resource was funded by the Spacelink Learning Foundation and written by Sheffield Hallam University. It is aimed at students between 14 and 16 years of age. The resource investigates the idea of alien life, and consists of eight exercise sheets for students:

*Earth Calling looks at messages that have...

Lift Off!

This resource, from the European Space Agency, contains exercises in physics and chemistry based on real space data, designed for secondary schools. The exercises and data were developed and checked by ESA space scientists and engineers. They are most appropriate for students at Post 16 level. There are a total of...

Life in the Universe

Produced by the Royal Astronomical Society, this booklet examines the possibility of extraterrestrial life in the Universe. Many astronomers believe that there is life out there, but where is it? Is there life comparatively nearby, in our Solar System, or do we have to look to planets beyond the solar system that...

Life in the Freezer

If there is life elsewhere in our solar system it’s likely to live in a pretty cold environment. In this resource, students investigate the effect of antifreeze on the freezing point of water and how it can allow fragile cells to survive extreme cold. In the video, Judith Green explains how students can plan an...

Life in the Balance?

A Catalyst article about Earth’s biodiversity much of which appears to be teetering on the brink of a man-made extinction crisis. Scientists have suggested that, unless urgent action is taken now, many species will disappear in the next 50 years. This article looks at some of the issues involved.
