In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water). Learners compare how and where a cork moves before and after the waves. Learners discover that the cork moves in a circular motion. This resource also includes information about waves, crests, troughs, and wavelengths. [Activity is publicly available through a web crawler capture on Archive.org.]
