Did you know that lightning bolts can be over a mile long? Or that they may come from clouds that are ten miles high? Storms can be scary, but not if you know what causes them. Before the next thunderstorm, grab this book by veteran science team Franklyn Branley and True Kelley and learn what causes the flash, crash, rumble, and roll of thunderstorms!

Kindergarten-Grade 4This useful book, first published with humdrum illustrations by Ed Emberley (Crowell, 1964; o.p.), underwent a major metamorphosis in 1985, with a rearranged and revised text accompanied by colorful, inviting illustrations by Barbara and Ed Emberley. Now, in a general revamping of the entire series, this simple treatise on thunder and lightning has been transformed. The text contains minor revisions, and Kelleys watercolor illustrations are bright and appealing. Diagrams are clearer and labeling promotes easier interpretation. Also included, for active home investigators (or enthusiastic classroom teachers), is a page containing two simple weather experiments and a list of three Internet weather sites.
