Now a Netflix series! #1 New York Times Bestseller A Wall Street Journal Bestseller A USA Today Bestseller Inspired by mathematician Ada Lovelace and physicist Marie Curie, this #1 bestseller champions STEM, girl power, and women scientists in a rollicking celebration of curiosity, the power perseverance, and the importance of asking “Why?” Ada Twist’s head is full of questions. Like her classmates Iggy and Rosie (stars of their own New York Times bestselling picture books Iggy Peck, Architect and Rosie Revere, Engineer), Ada has always been endlessly curious. Even when her fact-finding missions and elaborate scientific experiments don’t go as planned, Ada learns the value of thinking through problems and continuing to stay curious. Ada is an inquisitive African American second grader who was born to be a scientist. She possesses an unusual desire to question everything she encounters: a tick-tocking clock, a pointy-stemmed rose, the hairs in her dad’s nose, and so much more. Ada’s parents and her teacher, Miss Greer, have their hands full as the Ada’s science experiments wreak day-to-day havoc. On the first day of spring, Ada notices an unpleasant odor. She sets out to discover what might have caused it. So Ada uses the scientific method in developing hypotheses in her smelly pursuit. The little girl demonstrates trial and error, while appreciating her family’s full support. In one experiment, she douses fragrances on her cat and attempts to place the frightened feline in the washing machine. For any parent who wants STEM (Science, Technology, Engineering, and Math) to be fun for their girl (or boy), this book is a source of inspiration that will get children excited about science, school, learning, and the value of asking “Why?” STEM favorites from #1 New York Times bestselling team Andrea Beaty and David Roberts!Rosie Revere, Engineer * Iggy Peck, Architect * Rosie Revere and the Raucous Riveters * Ada Twist and the Perilous Pants * Ada Twist’s Big Project Book for Stellar Scientists * Iggy Peck’s Big Project Book for Amazing Architects * Rosie Revere’s Big Project Book for Bold Engineers * Ada Twist, Scientist 2023 Wall Calendar
