This Catalyst article looks at thorium - a heavy element, similar to uranium. Some people think that it could be the nuclear fuel of the future, as it can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.

This video explains how our preconceived ideas of how objects move can distort our understanding of Newton’s laws of motion, creating misconceptions.

1.            An object with no unbalanced force acting on it will naturally come to rest.

2.            An unbalanced force causes an object to move...

This video is a message to ESERO-UK from European Space Agency astronaut Tim Peake. He talks about studying STEM subjects and how he became an astronaut. The video includes images of a launch, Tim engaging in various astronaut training exercises and the International Space Station, where Tim will be for six months...

As part of the educational activities around the British astronaut Tim Peake's mission to the International Space Station (ISS), this project offers schools the unique opportunity to access and analyse ionising radiation data from the ISS. A variety of data sets will be available from the start with others being...

Produced by the Royal Observatory Greenwich, this booklet introduces time dilation and the Schwarzschild radius of a black hole. Included is an online video that discusses what is inside a black hole and how light and time behave near one. Equations for time dilation and the Schwarzschild radius are introduced and...

Purpose: An important form of investigation that can be difficult to manage in classrooms is ‘observation over time’. Fixed length lessons reduce the number of possibilities for observation to those changes that occur within minutes rather than hours. One solution to this problem is to use time lapse photography to...

A Catalyst article about neutrinos. Neutrinos are fundamental particles. They are tiny, a neutrino has a mass about one-millionth of the mass of an electron, and they have no electric charge. This article looks at the detection of these elusive particles which requires the use a giant detector. The one described is...
