During a Science unit on the Solar System, students must recognize that the Earth revolves around the Sun in a year and rotate on its axis in a 24 hour day. Many students have a hard time grasping this concept. Through this Smartboard lesson, students can learn or review the terms revolve and rotate. The 27 page slides include: definitions with pictures of rotate and revolve, then individual cards (with pictures) students read and answer. Students slide text to another box that will reveal answers to questions. This can either be done as a review game with class or can be set up as a center. It is a great way for students to learn concepts of revolution or rotation.
