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.

These two activities, from the Royal Observatory Greenwich, involve using the website Galaxy Zoo to classify five samples of ten galaxies. The results are recorded in a table and presented in the form of a bar chart for each sample. These can be drawn on paper or plotted using...

Produced by the Royal Observatory Greenwich, this teacher led booklet gives instructions on using the GalaxyZoo website to investigate the different types of galaxies in the Universe. It uses the context of galaxy classification to develop analysis and statistical skills and requires that the students have access...

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.

The Games and Activities sub-collection contains two resources with activities including modelling a lunar landscape using light and shadow and ordering things in space sequentially.

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 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.

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 book looks at several aspects of gears and gearing: * Chain drives * Belt drives * Spur gears * Compound spur gears * Worm gears * Contrate and helical gears * Cams * Design and build problems Gears and Gearing was one of the Science at Work series. All the booklets in the series were highly illustrated with...
