Seedy Travelers

In this activity (on pages 18-28), learners explore how the shape of seeds affects how they are dispersed by wind, birds, ocean currents and other means. Learners make predictions about seeds' ability to travel, and build devices to test their predictions. Tests include the Roll Test (rolled onto a target from a height), the Hitchhiker Test (a fuzzy cloth), and the Fly Test (distance from blowing). The "What We Know" introductory section introduces some of the various and amazing ways that seeds travel to locations far away from the plant the released them.
