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 series of resources from Defence Dynamics uses military contexts to teach aspects of science.

*Carbon and the Carbon Cycle- two activities look at the carbon cycle, its imbalances and how carbon, in the form of fuel, is obtained.

*Conservation - an activity which...

 These materials look at three possible projects that relate to sustainable travel.

* Communications project - students gather information and explain about ‘green’ transport policies, reducing and offsetting carbon footprints.

* Practical project - students investigate how to compare carbon dioxide...

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...

In this lesson students explore data showing how much carbon dioxide different species of tree absorb from the atmosphere.

Students interpret data, statistics, graphs and infographics and make predictions and draw conclusions in the context of considering why trees are good for the environment. Students will...

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...

One of a series of short videos from Liverpool University focusing on Carbon Dioxide levels in the atmosphere....

This resource uses the context of tornadoes in the solar atmosphere to investigate circular motion and energy changes. A hole is drilled in the bottom of a washing up bowl and orange pith can be used to track the motion of the water when draining through the bottom and creating a vortex. The Key Stage Three...

In this activity developed by the Institute of Physics, students investigate how temperature changes with distance from a heat source and relate this to planetary temperatures. After completing this activity, students should be able to:

*Understand that the temperature of a planet depends on its distance...

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.
