Looking through a microscope, Red Kangaroo discovers the world is full of small things her eyes can't see. She asks Dr. Chris, 'What's one of the smallest things in the world?'

In his lab, Dr. Chris introduces Red Kangaroo to the world of atoms — from protons to electrons to neutrons.

In this new series, Chris Ferrie answers all the questions Red Kangaroo has for him about what things are made of and how things work using real-world and practical examples. Young readers will have a firm grasp of scientific and mathematical concepts to help answer many of the 'why' questions they may have.
