Where to buy it


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.

Like most kids, Mike liked to draw and once he started to get recognition for his drawings, he drew more and more. He also liked to make people laugh, so put those two things together and you have a cartoonist on your hands.Many of Mike's funny ideas come from observing the world around him and twisting everyday occurrences into funny and sometimes totally absurd cartoons, drawings and short animated films. Mike's cartoons and illustrations have appeared in many magazines, books and greeting cards in North America and Europe. His animated series, The Melon Shorts, has appeared in numerous film festivals around the world and has won a number of awards.Mike is the illustrator of the Gross Science series of books written by Edward Kay. The three titles in the series are Stinky Science, Germy Science and Poopy Science. Both Stinky Science and Germy Science are being adapted into an animated TV series. Mike is excited to be making his debut as an author-illustrator with the graphic novel Linty: A Pocketful of Adventure.Even on his most stressful and not-so-fun days, Mike reminds himself that he is making a living doing the thing that he had dreamed of doing when he was a little kid ... so he tries not to be too whiny.

Editorial Reviews

A great combination of scientific information, coupled with a bit of historical epidemiology, resulting in a highly entertaining and informative introduction to germs.—School Library Journal (Praise for Germy Science)

This book would be great for a home or school library; but it is doubtful that any reading period would be silent with it in the classroom. Expect titters, sharing and commentary.

Canadian Children's Booknews

This delightfully disgusting title exploring the science of stench is sure to hook young readers with yuck-appeal!—Canadian Children's Book News (Praise for Stinky Science)

A must read for everyone. Pull up a stool and get a whiff of this book!—CanLit for LittleCanadians

Fun, enlightening, and gross in all the best ways.

Kirkus Reviews

Bottom line, this book is so gross it's a must have ... 'this book belongs in every bathroom.' Make that every home, classroom and library. This one's a winner.
