Now available in Spanish bilingual editions, this best-selling series offers big, brainy science for the littlest listeners.

Accurate enough to satisfy an expert, yet simple enough for Baby, Quarks explores the basics of particle physics and chemistry - quarks, protons, neutrons, atoms and molecules - and ties it all to Baby’s world. Beautiful, visually stimulating illustrations complement age-appropriate language to encourage a baby’s sense of wonder. Parents and caregivers may learn a thing or two as well!
