From microwave ovens to the toaster, Household Inventions: From Toilets to Toasters is the story behind everyday technology. How were these modern conveniences invented? What problems did they solve? How did they make life easier? Students will discover the answers in this fun and informative book that traces the development of household technology through the decades. Each interior spread pairs two items, and then asks children which came first. A chart of paired items on each spread allows children to track their answers, while a set of bonus questions in the back encourages further investigation. Full-color photographs, accessible text, fact boxes, and a timeline will make every child a technology expert.
