This entertaining graphic novel from award winner Dan Brown will get kids talking, since it's all about the history of dealing with poop, pee, and dirty hands.Part of the Big Ideas That Changed the World graphic novel series, this full-color book is appropriate for the classroom and includes a timeline, endnotes, and a bibliography.In 1895, an engineer named George Waring was appointed New York City’s first commissioner of street cleaning. His task? To make a city with millions of people livable.Narrated by Waring, Keep It Clean! explores the concept of public health, which means ensuring clean water and adequate sewage disposal for everyone, and covers topics such as personal hygiene, sewer systems, and chemical water treatment.Acclaimed author-illustrator Don Brown takes readers on a journey through history and around the world, from Greek, Roman, and Aztec aqueducts and the dawn of bathing (including social public bathing in Japan and religious bathing ceremonies in Machu Picchu) to the invention of soap in the Middle East, the first use of flush toilets approximately 4,000 years ago, and the first toilets used in outer space—a Big Idea when you consider that early astronauts on Apollo 11 had none!Full of facts and colorful historical figures, Brown chronicles both historical mishaps—like rivers full of human waste and King Henry VI’s notorious basement of poop—and monumental scientific breakthroughs including Louis Pasteur and Robert Koch’s discovery of the link between microbes (germs) and disease.Brown also highlights how social classes became divided not only by wealth and culture but also by smell, and calls attention to modern-day health crises.Today, nearly two billion people around the world live without clean water and about 3.6 billion people—nearly half of the world’s population—live without proper sanitation. Breaking down concepts in an accessible, kid-friendly way, this nonfiction graphic novel shows why “keeping it clean” is vitally important whether it’s a city, town, home, or person.Big Ideas That Changed the World is a graphic novel series that celebrates the hard-won succession of ideas that ultimately changed the world. Humor, drama, and art unite to tell the story of events, discoveries, and ingenuity over time that led humans to come up with a big idea and then make it come true.More from the Big Ideas That Changed the World series:Rocket to the Moon!

More comfortable than flats!
Size: 8.5, Color: Bay Fog
I love these sandals! They run true to size, and they’re sooo comfortable. I was worried about getting fakes, but these were the real deal. The color is lovely (light purple). The foot bed can get dirty, but I find them to wash up nicely (by hand, not machine). I have purchased two more colors since! So much better than flats!

Comfy dual-mode sandals
Cute, quite comfy to walk in and love the support of the heel strap! It is not as comfy if using in slipper mode because the straps don’t keep your foot tight enough. I am usually a 8.5 but it runs slightly small so I switched up to a 9.

Love them
Size: 5.5, Color: Red Pepper
I have gotten so many compliments on these shoes! They’re true to size and comfortable. Because of the material feet might sweat easier if hot but they dry quick. Quality is great and the color looks good, it’s more of a orange/red color. I got a 5.5 size
