Whether it\'s in the Yard, in the House or elsewhere...Lisa Campbell Ernst delves into how common household objects--such as soap, scissors and house keys--work. The detailed, but easy-to-understand, language describes the functioning of everyday items, and Ernst\'s meticulous and cleverly labeled pictures are fascinating. How Things Work in the House is a marvelous companion to the much praised How Things Work Around the Yard. It also stands on its own as kid-compelling non-fiction.
