Satellite navigation is a key technology for today’s society, allowing for global navigation on land, at sea and in the air. The technology depends upon accurate atomic clocks, which help us...

Gaia is a European Space Agency satellite, mapping one billion stars in the Milky Way. 

This worksheet uses the context of the orbit of the Gaia spacecraft to look at circular motion and the gravitational force between two bodies.  The content is suitable for GCSE and A-level Physics.

A teacher's...

From ARKive, these resources help students to learn about the Galapagos Islands, their biodiversity and conservation. Through a series of activities, students look at: the scientific history and importance of the Galapagos Islands; the species that inhabit the islands including the concept of endemic species; the...

This video demonstrates that objects accelerate towards the ground at the same rate when in a vacuum.  Acceleration due to gravity is constant for all objects.

An investigation looking at how gamma radiation is absorbed when it passes through different thicknesses of lead.  From this you can then calculate the absorption coefficient for aluminium.  When doing this investigation please ensure you have followed CLEAPSS guidance or the safety body for your country.

NASA's Gamma-ray Large Area Space Telescope, or GLAST, is a space-based telescope that looks at the universe in the gamma ray wavelengths. This telescope will study known sources of gamma rays in detail but will also discover thousands of new gamma-ray sources in its five-year mission. This resource has an image of...

This Nuffield Working with Science unit set out to foster an interest in growing things and to encourage more careful observation of detail with things as familiar as cabbages and tomatoes. Students are required to show a certain amount of practical dexterity, some...

This Catalyst article investigates how plants can be grown in orbiting spacecraft and how this may be useful in future manned space missions.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.

Catalyst is a...

This simulation allows students to pump gas molecules into a box and see what happens as you change the volume, add or remove heat, change gravity, and more. They can measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

Sample learning objectives...

The Gravity Jet Suits use five small gas turbines to create enough lift for a human to fly.  This resource explains how the gas turbines work, and how this relates to Boyle's Law.

This Catalyst article looks at how you can collect iron micro-meteorites using a magnet.
