Almost New - appears new but is actually secondhand.
Very Good - only minor imperfections such as minor scuffs to edge or cover or a price written in pencil or shop sticker.
Standard Secondhand - Clearly been read before, but not too bad. We do not recommend these for gifting. Spines usually creased. Could also include creases or folds to cover, some writing such as in the cover or elsewhere, underlining or highlighting, but might not do. Possibly some stains or marks. Similar in general to books in any secondhand shop or charity shop.
Poor Condition - Usually this will have a specific problem such as writing inside, water damage, missing dust jacket, heavy staining, large creases or cuts. These are readable copies but not nice ones. On other websites this condition is called 'Acceptable' or 'Fair' , but we want to be more honest.
This practical book answers common questions about materials by looking at evidence and demonstrating their properties through a range of carefully chosen experiments that can be done in the classroom or at home. It covers such questions as 'What are states of matter?', 'How does heat get through materials?', 'What happens when a solid dissolves?' and 'What are chemical changes?' It also includes questions for readers to investigate further on their own. Written by a highly experienced and acclaimed science writer, the book includes links to useful websites as well as glossary, index and list of further reading.
