How do scientists share ideas across the world?


Mole and Tell gives kids their first taste of universal standards of measurement, teaching them about scientific notation in a way that’s fun and easy to understand. Mr. Cantello’s classroom is full of lively characters who ask the same questions a young reader is wondering—like how can a mole of sugar be larger than a mole of water, and how is it possible to measure something smaller than you can see? Mole and Tell introduces readers to concepts like the periodic table, molar mass, elements, and of course, moles. Using the familiar activity Show and Tell, readers will explore several different measurements of moles. The story is grounded in fact and shows kids how science is used in the real world. Written by authors with years of experience working with children, this book is a snapshot of the dream classroom experience. After finishing this book, readers will look forward to having a Mole Day celebration of their own!
