This Catalyst article investigates the research into artificial photosynthetic systems.

With the world’s population ever-expanding, energy demand is expected to double by 2050 and triple by 2100. In only 200 years, mankind has squandered what nature has taken hundreds of millions of years to lay down as...

This resource, from the Royal Observatory Greenwich, begins with a video that names and describes some the different layers of the atmosphere, with the aim of explaining where the ...

This unit looks at 'geoengineering', which is the implementation of large-scale interventions into the Earth's climate to reduce the impact of climate change. This includes the removal of carbon dioxide from the atmosphere or reflection of solar...

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...

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface...

This short video from Liverpool University focuses on carbon dioxide...

This Catalyst article looks at NASA's Mars Curiosity rover, the automated chemistry lab which landed safely on Mars in August 2012. Capable of analysing samples from the planet's surface and atmosphere, the rover will undertake two years of experiments in the hope of discovering even more about our neighbouring...

A Volcanologist studies the impact of volcanoes on the atmosphere and our planet as a whole. Volcanologists often work to try to understand how to better predict eruptions and minimise the effects on people arising from them. They may use computer modelling or satellite imagery and often work on or around volcanoes...

Produced by the Science and Technology Facilities Council (STFC), this wall chart describes the space mission to Mars, the experiments aboard, whether there is water on Mars, Britain's Beagle2 lander and the search for life on Mars. Mars Express was the European Space Agency’s first mission to Mars. Its role is to...

This Catalyst article investigates the healing of the ozone layer. The ozone layer in the upper atmosphere was damaged by CFCs, used in refrigeration. A ban on their use has allowed the layer to start recovering.

This article is from Catalyst: Secondary Science Review 2016, Volume 27, Issue 1.

A great deal of space exploration is performed by autonomous craft. They have mapped remote planets and even landed to send surface data back to Earth. Satellites have changed the world of communication, earth observation and, through global positioning systems, everyday navigation. This collection, with...

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...

In this unit from the Geology: Structure of the Earth series, produced by Northumberland County Council, students discover more about the Earth's internal structure. In a series of tasks, students investigate the true shape of the Earth, gravity and how geologists use it, movements of the Earth and what happens...
