Elementary graders enthralled but thoroughly confused by the labyrinth of facts about planets will emerge triumphant from this basic description of the nine planets that revolve around the sun, their temperatures, relative sizes, atmospheres and satellites. Where they are located in relation to the sun, the earth and each other, what characteristics distinguish each one, and some of the unknown avenues open to discovery are the major topics explored via the doubly effective technique of clear language involving the child's experiences, and colorful eye-catching illustrations supplied by Leonard Kessler. Basic, and incidly presented, this is recommended for use both inside and outside the second through fourth grade classrooms.
