How Come It’s Windy? 

Ever wonder what makes the wind blow? How fast does the wind blow? Readers learn the answers to these questions and many others, as they start reading about the wind. Ideal for read aloud or for early readers to read on their own, this fact-filled, full-color book also supports the National Science Education Standards for Grades K to 4 Science. Young weather scientists will want to try the experiment, "How hard is the wind blowing this week?" to satisfy their curiosity.
