When Oma arrives to stay with Jake, Lizzie, and their parents, they want to make her visit extra special -- so off the family goes to Jake's birthday party, the library, the beach, and many other places. These familiar childhood excursions prompt many questions. How do candles stay on fire? How do librarians remember where all the books go? How does the sand get so hot? Curious kids everywhere want to know -- and no adult has all the answers. In the same style as the bestseller Why?, How?provides kid-friendly explanations for nearly 100 everyday mysteries. Bright, playful illustrations complement the clear text. A scrapbook-style page at the end of each chapter offers additional information in snapshots and captions. How?combines the best qualities of non-fiction and picture books to delight young readers again and again.
