Carolyn Porco: Could a Saturn Moon Harbor Life

In this talk, courtesy of TED, Carolyn Porco shares exciting new findings from the Cassini spacecraft's recent sweep of one of Saturn's moons, Enceladus.

Samples gathered from the moon's icy geysers hint that an ocean under its surface could harbour life. Scientists were initially excited by the discovery...

Autonomous navigation

Dr. Mark Woods explains how the rover technologies must be partly autonomous, since the signals from Earth to Mars take too long for every command to be send from Earth.  The technologies developed for space, also have applications on Earth.

This video is part of a series of ten which look at the one of the...

Mission X: train like an astronaut

Mission X is supported by the UK Space Agency, ESA and NASA. It is a free education programme developed by NASA scientists and fitness professional working with astronaut and space agencies across the world. Mission X uses the excitement of space exploration to inspire students to learn more about nutrition,...

Martian Death Rays

Could there be life on Mars? Perhaps so, although the high intensity of UV light means that it is unlikely to be found on the surface. The experiment demonstrates how bacteria grown on agar plates can be killed off by UV exposure. Curriculum areas covered: • Microbiology • Cell biology • Aseptic technique The video...

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...

Learning Outside the Classroom

Part of the Great Lesson Ideas series, this Teachers TV video looks at how secondary science topics can be taught away from the classroom. It shows at ideas for three great day visits.

These include:

• The Goonhilly Satellite Earth Station, in Cornwall, to learn about satellites, space and...

Is There Life In There?

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 starch, sugar,...

I Am a Star

This resource is based around the chemical composition of the human body and the origin of elements in the universe. Students can input a mass in the spreadsheet to see what proportion of their mass is from elements created in the Big Bang, in stars and in supernovae. Graphs are also shown for the relative...

How the Leopard Gets Its Spots

The animal kingdom contains an abundance of exquisite natural patterns from the stripes of an angelfish to the spots of a leopard. But how do these arise during early development? This Catalyst article looks at Turing mechanisms as a way of explaining how patterns develop as an animal grows.

In 1952, Alan...
