This resource from Physicists in Primary Schools (PIPS) supports the teaching of [b]light[/b] at Key Stage Two. A presentation introduces sources of light and how we see them, demonstrating how we see objects, reflection of light, composition of white light and primary colours. The presentation is interspersed with...

These activities, produced by Gatsby Science Enhancement Programme, help students to think about collecting and presenting information.

In this activity, students compile and edit a science book by collecting news items from print and internet sources. This allows students to think about the ways that...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Calculate momentum using p = m x v.
• Describe what happens to the motion of objects colliding head on. 
• Determine changes in momentum, Δp.         
• Explain and use...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recognise that an element symbol in a chemical equation can represent a giant covalent structure.
• Recognise that a chemical formula can represent a giant covalent structure.

The materials in this collection have been developed by the Centre for Science Education to support the network of Inspire science clubs. The materials are activities which can be used to enrich the curriculum, as part of a science club activity, or to help primary school children to understand scientific concepts...

This edition of Computer Science for Fun examines how computer science has improved the safety of medicine and hospitals and how accidents have happened in the past. The articles include:

• Therac-25 cancer therapy – safety-critical applications

• Programming magic tricks

• Human-Computer...

Work done in this Nuffield 13 - 16 module followed from the S unit called ‘Rockets and momentum’. This S unit provided enough material for eight double periods during a single-certificate science course. The teachers’ guide included eight worksheets to supplement the...

This edition of Computer Science for fun asks ‘Can Machines be Creative?’ The articles inside include:

Produced by the Science and Technology Facilities Council (STFC), this A4 colour brochure describes the leading role played by UK scientists and engineers at universities, observatories and research council establishments in the Cluster mission that is currently exploring the Earth's space environment. The European...

Design and make a seed from a newly discovered plant using junk materials.This activity provides an opportunity for creative thinking around the topic of germination and seed dispersal. It also supports the development of literacy and presentation skills. Further ideas...

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface...
