This illustrated book is a fun way to get young astronomers ready for August 2017, when millions of North Americans will have the rare chance to witness a total solar eclipse. The book tells how two curious children and their grandparents re-create eclipses in their living room using a lamp, a tennis ball, two Hula Hoops, and table tennis balls. Later, in the backyard and around the house, the family explores safe ways to view a solar eclipse and ponder phenomena from sunspots to phases of the Moon. Written by the authors of NSTA’s award-winning book Solar Science, When the Sun Goes Dark gives children and adults hands-on techniques for learning the science behind eclipses of the Sun and Moon.
