Beskrivelse
Key science concepts, such as mass, weight, and density are explained through engaging, accessible text. Labeled photographs introduce readers to a range of scales and balances, including triple-beam balances, spring scales, and digital scales. Handy tips and discussions on which situations each tool tends to be used in provide pivotal information for readers. An experiment they can do at home, using a small scale or balance and common kitchen ingredients, is also included.
