||New plants poke through the soil. Birds build nests and lay eggs. Kids play outdoors longer after school. What does it all mean? It must be spring! From changes in the growth cycles of plants to the signs of spring that can be found in backyards, parks, woodlands, wetlands, cities, and farms all across North America, this colorful book will give kids an exciting opportunity to explore nature in action. Activities, such as recording relative changes in temperature, precipitation, and the length of days in weather notebooks, give readers a chance to gain insights beyond the facts and figures.
