From tracking spring peepers and raising tadpoles to learning about seeds and recording plant growth, this activity book invites young readers to explore the wonders of spring by becoming scientists in the field. Combining hands-on learning with solid science, trivia, riddles, and terrific illustrations, projects investigate "the reason for the season" and include identifying trees and measuring their growth, recording soil temperature, and observing the forest floor. Bird migration and nest building are covered, and the movement of air and water is studied with experiments in capillary action and in such activities as "Making Parachutes," Making Kites," and "Mapping Air Currents with Bubbles."
