By constructing a model of the constellations in the zodiac, students can learn about the relative motion of the Sun and the Earth. Students can find their own star sign and discover how the view from the Earth will change as the Earth orbits the Sun. The model allows them to see how the night sky changes over a...

On 30th June in 1908 the largest asteroid in recorded history smashed into Earth in Siberia. This date is now used as an opportunity to highlight the risks of asteroids to equipment in space and the Earth; and their positive effects such as their role in the formation of the solar system and asteroid impact sites...

On 14 January 2005, the European probe Huygens entered the atmosphere of Titan - one of Saturn's moons. Based on this major event in space exploration, ESA offers a cartoon-style teaching aid with fact sheets for teachers to use in the classroom. The factsheets are available for use with different aged students -...

This collection contains a selection of videos relating to themes concerning climate change.

The first collection focuses on the rise in Carbon Dioxide levels in the atmosphere over time. The second resource offers three perspectives on...

Because of the shape of the Earth’s orbit around the Sun, it is farther away from the Sun in July than it is in January. Still, we have colder days in January than in July. How is this possible? Through this mystery, students will investigate the orbit of the Earth around the Sun and its influence on solar energy...

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 takes a slightly different slant on how plants can help reduce the build up of carbon dioxide in the atmosphere and thereby help prevent climate change.  In the video Ben Ainslie, Olympic gold medallist and driver for the Great Britain SailGP Team, explains how seagrass can be used to reduce carbon...

Classroom Space was developed by the University of Leicester with a grant from the Particle Physics and Astronomy Research Council (PPARC). It was designed to use the context of space science and astronomy to teach science in the secondary school curriculum. The resources are: * Water on Mars? * Weathering on the...

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...

These resources from the European Space Agency climate change initiative education resource pack allow students to learn about how the ocean circulation has an impact on the climate. This redistribution of heat around the Earth 'planetary heat pump' supplies warmer water to the poles and influences the rate at...

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...

Astronauts have been taking photographs of the Earth from space for over 50 years and Earth Observation scientists have used satellite images for a similar amount of time.

The EO Detective activities aim to demonstrate how a vantage point in space, such as the International Space Station, provides a unique...
