Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

Radius and Volume of Exoplanets

This activity, from the Royal Observatory Greenwich, uses data from NASA’s Kepler space probe to determine the size of an exoplanet, and provides students with an insight into the advantages and disadvantages of the transit method of exoplanet detection.

A classroom discussion, before the activity,...

Principia mission - maths in space

On December 15th 2015 European Space Agency astronaut Tim Peake launched on the six month Principia mission to the International Space Station (ISS). Principia was named after Isaac Newton’s Naturalis Principia Mathematica, describing the principal laws of motion and gravity.

Getting Gaia going

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

This worksheet guides students through some calculations on the power requirements for the Gaia spacecraft, the content is suitable for GCSE and A-level Physics.

A teacher's guide gives worked solutions.

Galaxy Zoo and the Universe

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...

Gaia's place in space

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...


These Fun-Size materials, from the Association for Science Education (ASE) are short 5-15 minute activities that enliven lessons. These are part of the SYCD AKA Science collection. They range from short games and word plays through to quick demonstrations. Fun-size is particularly useful when you are working...

Fission and Fusion: a Physics Kit

This resource, produced by SEPNet and Queen Mary University of London, uses Lego to represent the building blocks of matter. Different colour and size Lego bricks are assigned to protons, neutrons and electrons. Fusion is shown by joining bricks together and fission by breaking large collections of bricks apart....

Exploring Saturn

A Catalyst article following the journey of the space probes Huygens and Cassini, sent to explore Titan, a moon of Saturn. After a seven year journey Huygens was set to fall through the atmosphere transmitting data back to Earth via Cassini so more can be learnt about this distant moon. The article describes the...


In this activity, students are required to find a safe route through a notoriously perilous region of space called the Twilight Nebula.

They will be faced with a number of different threats but can maximise their chances of survival using a series of threat assessment readouts. Students will compare fraction...
