Shape It Up is one of many good educational games and activities on Kinetic City. Shape It Up is an activity that would be good for use in an elementary school Earth Science lesson. The activity presents students with “before” and “after” images of a piece of Earth. Students then have to select the force nature and the span of time it took to create the “after” picture. If students choose incorrectly, Shape It Up will tell the student and they can choose again.
