Easy-to-do experiments will help parents and kids discover the ways water, wind, sand, plants, animals, and people interact to shape the constantly changing beaches we love to visit. Featuring colorful illustrations and clear instructions, most activities require nothing more than an observant eye and simple tools found at local stores. You will learn about geology, weather, waves and currents, the critters that live on our beaches, and the environmental issues that threaten them. Chapters also include indoor activities for rainy days and activities for nighttime discovery. This book will become an indispensable companion for families, teachers, and students heading to the Carolina coast for years to come.
