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, this
clever board book explores the ups and downs of gravity. When baby drops
food from a high chair, why does it fall? Beautiful, visually
stimulating illustrations complement age-appropriate language to
encourage baby's sense of wonder. Parents and caregivers may learn a
thing or two, as well!
