Readers may never expect that they might free fall to Earth, but if they have ever dived into a pool, that's exactly what they've done. This title shows readers how Newton's three laws of motion affect divers, skydivers, and mountain climbers' movements. Readers discover who uses gravity, who works against it, and all other forces that contribute to a successful dive or climb. After reading this title, readers can decide if they will ever be interested in engaging in one of these extreme sports. This 6-Pack includes six copies of this Level S title and a lesson plan that specifically supports guided reading instruction.
