This video considers the misconceptions people have about heat. Most people believe that something that feels hotter to the hand must be at a higher temperature. However, this is not always the case. We do not feel temperature, rather we feel the rate at which heat is conducted towards or away from our hands. Two...

This video introduces the Hubble sphere and how the rate of expansion of space can be used to explain how we see very distant objects that are travelling faster than light. The limitation to the observable universe is the particle horizon (where the time is too great for light to have reached the Hubble horizon)....

These Key Stage Three National Strategy training materials from the Department for Education are designed to run a session with science teachers to help them: *identify commonly held misconceptions (alternative conceptions, alternative frameworks) *establish the importance of models and analogies *identify...

Mission X is supported by the UK Space Agency, ESA and NASA. It is a free education programme developed by NASA scientists and fitness professional working with astronaut and space agencies across the world. Mission X uses the excitement of space exploration to inspire...

This resource is set in the context of challenges encountered in getting to, landing on and living on Mars.

The resource covers some mathematics, physics and biology:

• Launch crew: How many people can you fit in different spacecraft modules.  Mathematics.
• Launch aerodynamics: Investigate...

A Catalyst article about BepiColombo, a spacecraft which will visit Mercury, powered by a revolutionary new rocket engine technology using ion engines and using a slingshot manoeuvre to accelerate it. The development of the spacecraft is an international project and will combine exciting scientific goals exploring...

This collection of practical activities, investigations and games is all based on current lunar research. It supports many aspects of working scientifically and links to area of the curriculum including: earth and space, light and shadows, forces, materials, changes of state and rocks and soils. Activities are...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Visible light is the region of the electromagnetic spectrum with which we are most familiar. We are able to distinguish between different...

In this activity, students investigate the potential effects to health of the use of mobile phones and their transmitters, which use radio waves and microwaves to transmit information. Research can include the electromagnetic spectrum and its applications and how energy...

Microwaves are a form of electromagnetic radiation and they penetrate into human tissue. There is still a significant debate about the safety of holding even a low power microwave transmitter next to your brain or keeping it in a trouser pocket. The possibility of...

This Science upd8 resource examines what proof there is that mobile telephones are harmful. Policy makers usually follow the precautionary principle. They issue warnings at the first hint of danger. Should we take their advice? In this discussion activity, students judge the risks and the strength of the evidence...
