Whiz Kids Tell Me How Fast It Goes

The Whiz Kids are a group of children - and a dog - who explain scientific subjects in a simple and friendly way. This book gives lots of simple facts about movement in a clear and concise way. The information is brought to life by child-friendly practical experiments which allow children to see science at work for themselves. Young readers are helped to observe, explore and ask questions about movement and speed. Investigative skills are developed through the use of simple "how", "what" and "where" questions. This book introduces the concept of friction and describes how speed is measured.
