In this grades 3-5 lesson from National Geographic Xpeditions, students will learn about the varying heights of ocean waves and what causes the variation. They will begin by learning the parts of a wave, and then discuss the meaning of wave height and wavelength in terms of various points of reference. A demonstration will spark discussion about how geography affects wave heights, and will allow students to experiment with various forces to create different sized waves. Students will use the National Geographic Wave Simulator to experiment with creating different types of waves, and will draw waves based on the heights and lengths of familiar structures around the school. This lesson includes information about tsunamis.
