This video explores how technology has always been expected to replace teachers.  It concludes that a teacher’s purpose is not to transmit information, but to guide the social process of learning. To challenge, inspire and excite their students to want to learn.

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...

In this Core Maths task students explore the question ‘On average, how many throws does it take to throw a six?’ Through this activity students can gain an understanding of ‘expectation’ as well as learning how to calculate summary statistics when the data is given in a frequency table.

Throwing a...

A selection of resources where you can find out more about British Astronaut Tim Peake and his mission to space. 

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...

Tin cans come in a variety of shapes and sizes. In this activity students consider the net of a tin can, the formula for the total surface area and the formula for the volume of the can. The first problem requires students to express the total surface area as a function of r by eliminating h. The second problem...

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...

A Catalyst article about the study of electrical activity of the brain during sleep. The article looks at brain waves, REM (Rapid Eye Movement) and the effects of sleep deprivation.
