The 'Whiz Kids' are a group of children - and a dog - who explain scientific subjects in a simple and friendly way. The book gives lots of simple facts about gravity, planes, air and flight in a clear and concise way. The information is brought to life by child-friendly practical experiments, which allow young readers to see science at work for themselves. In the subject of Science: Key Stage 1, the book helps young readers observe, explore and ask questions about flight. Investigative skills are developed through the use of simple 'how', 'what' and 'where' questions. The book encourages children to explore 'a range of domestic and environmental contexts that are familiar and of interest to them'. In case of Literacy: Key Stage 1, the book introduces children to the conventions of non-fiction texts. The book contains organisational features common to most reference texts: a contents page, captions, illustrations, an index and glossary. Also helps to achieve the goals of the Scottish Standard Curriculum 5-14, promoting 'positive attitudes to learning', 'knowledge, understanding and appreciation of the world' and 'skills in literacy'.
