Straightforward Science is just what its title suggests--a straightforward introduction to key science subjects. Each book explains the main scientific principles involved and shows how they work--from our everyday world to outer space. 'Food Chains' introduces the basic science behind food chains and presents experiments to show how they work. Clear photographs and diagrams complement the text, and simple experiments involve the reader in the search for knowledge.
