Divided into sections, the book starts with fast facts on topics including the rock cycle, crystals, ores, fossils, and rocks from space; and the book ends with charts of rock facts and record breakers. Using this information, you can complete the puzzles in the main part of the book, plus there are hands-on activities such as growing your own stalactite and testing the hardness, streak, and specific gravity of rocks you have collected. Finally, test your new-found knowledge with the quick quizzes (with answers supplied, but no peeking!). You can keep track of your achievements throughout with a star-chart to fill in every time you finish a page. Note to parents: The Eyewitness Project Book series is devised and written with the expert advice of educational and reading consultants and is designed to appeal to children aged 8 years and up.
