When Mr. Cantello’s fourth graders see a strange date written on the board, they learn that Mole Day is coming soon... but what is a mole? And what does it have to do with their science class? 


In this fun and accessible explanation of Avogadro’s number, six inquisitive kids use the power of their curiosity to put together a Show and Tell like you’ve never seen before. 


In the first book of the Celebrate Science series, join the class for a delightful introduction to scientific measurements—and a Mole Day celebration to remember! 

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.
