Part of the Gross Science series, here's a book flush with facts on the number-one topic of interest to kids: going number two! Overflowing with the science and history of poop (and pee), Poopy Science covers everything kids ever wanted to know (and more!) about their favorite subject. Both expertly researched and hilarious, this book starts with human waste, including: what's in our poop, how our digestive system works, what poop can tell us about our health, and the history of sanitation. It then moves on to other fascinating topics, like: why some animals eat poop, potential ways poop can be used for fuel and how astronauts poop in space. Packed with silly puns, this book takes the throne as the world's best bathroom reader! Outrageous, kid-friendly and easy to digest, award-winning author Edward Kay's engrossing text is a solid source of information and entertainment. The hysterical comic-style art by Mike Shiell enhances the engagement factor. This is definitely a book kids will pore through on their own! The appealing blend of science and history content gives the book plenty of cross-curriculum links in life science, particularly the human body and human organ systems, technology, health and history. A table of contents, glossary, index and further reading make this a terrific resource. This is part of the enormously popular Gross Science series of thoroughly researched books presented with loads of humor and just the right amount of ewws.
