This series of interactive excel sheets investigate models involving collisions.

The first sheet simulates two particles colliding. Initial velocity, mass and resulting velocity of the two particles can be set, or a...

Produced in 2015, this resource looks at Human survival in a closed system on Mars. 

Student activities include:

• Identify the basic requirements for Human life on Earth

• Understand the concept of a closed system and understand why the Earth, a space craft and Mars are all closed systems and...

This is one of the 14 Background Books published for Stage III of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book describes developments in the applications of chemistry but takes an historical approach in some sections.
