This is a great book with a lot of information packed into its 70 pages. It is structured around a series of 'experiments' or 'projects'. Some of these can be completed with young children (e.g. project 4: making a sundial) whilst others will stretch teenagers (e.g. Project 19: Making a Dobsonian telescope).
None of the projects need specialist equipment and I used the book to guide some children aged 8 and 9 to make a simple astronomical telescope (Project 14: the lenses cost £2 from poundland. A jewelers 'Loupe' and a magnifying glass).
This book is a great treasure and has bought pleasure to everyone who has got their hands on it. Cover price is £5.95 but at the moment Amazon has them new for half price.
