Oh, Ick!: 117 Science Experiments Guaranteed to Gross You Out! baixar o livro de graça

Kids love to be grossed out. In "Oh, Yuck!" and "Oh, Yikes!" (which together have over 1.25 million copies in print), the doyenne of disgusting, Joy Masoff, offers up all sorts of gross, stinky, slimy, creepy, weird, and wacky phenomena. She now brings us OH, ICK!, the book that finally lets kids get their hands dirty really dirty with 117 interactive "ick"-speriments and "ick"-tivities that delve into the science behind everything disgusting. Here is an A-Z compendium of hands-on grossness, with projects explained in easy-to-follow step-by-step instructions accompanied by in-your-face how-to photographs. Stage an Ooze Olympics to demonstrate viscosity and the nature of slime. Observe how fungi grow by making a Mold Zoo. And learn what causes that embarrassing acne on your face by baking a Pimple Cake to pop and eat. Ewww! Accompanying each experiment are lots of fascinating facts and a detailed explanation of "What Just Happened?" (Did you know that there are a billion billion insects in the world? Or that the color of earwax is genetically determined?) Masoff s coauthors are experienced educators who ensure that the book targets important curriculum points. So while kids will love the gross-out factor of these projects, parents will love the real scientific principles and skills they teach."
