Did the princess really feel a pea under 20 mattresses? It seems hard to believe! The princess retells her epic tale and uses the scientific method to investigate. After numerous experiments, will the princess have an answer? Can science reveal the reason behind her exceptionally bad night's sleep? Each title in this series follows a simliar format: the scientific method is presented, a familiar story is retold in a humorous way, and the main character puts science to work. The third little pig demonstrates that air can move some materials more easily than others. Golda Locke shows that observation can help determine which porridge is the right temperature to eat, while a princess proves three peas cannot be felt under 20 mattresses. Every book ends with a kid-friendly experiment for readers to try on their own, such as testing whether a heavy object would have fallen from the beanstalk faster than a lighter object. The books have cartoon-style illustrations that fit the lighthearted approach. Readers are sure to notice that Red Riding Hood, the Gingerbread Boy, and other characters are at the market when Jack goes to sell his cow. VERDICT These books are an entertaining way to introduce the scientific method and would be a fun way to kick off a STEM activity.--Suzanne Costner, Fairview Elementary, TN "School Library Journal" Gloria Koster is a school librarian and an author of many children's books.
