Hello World! Weather, takes children through the seasonal changes in a backyard, allowing a child to compare how a yard changes throughout the year: on a sunny day the flowers are bright and a puppy plays on the green lawn; on a snowy day we see the same yard blanketed with snow; on a windy day the clothesline flaps in the breeze. Children can also have fun pointing to images of the different clothing we wear in each type of weather: mittens, hats, rain boots, and more. It's a perfect way to bring the outside world of natural science into the busy world of a toddler, where learning never stops.
