Although quite an advanced looking book for this age group it is exceptionally clearly written. For the older end of the 7-12 age range. Describes how the Earth is made, beginning with the structure of the Earth and plate tectonics, and continuing with how rocks are made, some principles of the physics of light, electricity, heat, sound, and so on, and concludes with a section on the solar system. It is a thorough and readable reference with a good system of cross-referencing and some good clear diagrams and photogaphs. Most of the book is in full colour.
Questions scattered through the book have answers at the back.
For the older end of the 7-12 age range. It has a magazine style layout, with short items under each heading, large coloured photographs and diagrams. It presents its information and message very effectively, without losing its way by being over-emotional. Another Survival book by Michael Bright, Pollution and wildlife , comes to the point quickly and concisely - 'Pollution kills'. It clearly explains what pollution is, shows why it kills, and how every person is responsible for disposing of their own rubbish responsibly.
