This video explains why objects of different masses fall at the same rate towards the ground. 

A heavy medicine ball is dropped at the same time and from the same height as a lighter basket ball.  They both hit the ground at the same time.

Although the medicine ball has a greater force on it, its...

This video shows the types of common misconceptions people have about heat.  A book and a metal object, that are the same temperature, are held by people.  They all say the metal object is colder. Using an IR thermometer, it is proved that a cake and its metal container are the same temperature as they are removed...

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)....

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...

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...

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...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP) and produced in partnership with the Walker Institute for Climate System Research. Climate scientists do not have a ‘climate in a test tube’ to try out their ideas, so to understand the...

From Teachers TV Lesson Planning Pack series, this video shows an example of how a lesson can introduce children to the idea of light travelling in a straight line. Rachel Dixon, a Year Six teacher at Ripple Primary School in Barking, presents her lesson on light. She aims to get her children to understand that...

This article investigates the history of models of the atom and discovers how, a century ago, scientists were devising models of the atom in an attempt to explain the limited evidence they had about the fundamental structure of matter.

The article is from Catalyst: Secondary Science Review 2015, Volume 25,...
