| A Model of Seed Dispersal |
| PBS |
| In this lesson, students will learn about one particular method of seed dispersal, through foods that animals eat |
"Plants have evolved many different strategies for dispersing their seeds: think of "helicopters" on a maple tree, the fuzzy head of a dandelion, or the tiny, sticky pods that sometimes attach to your pants, socks, and shoes as you walk through open fields. In this lesson, students will learn about one particular method of seed dispersal, through foods that animals eat. Animals that eat fruits can't digest the seeds of the fruit, which pass unharmed through the digestive tract and are deposited on the ground some distance from the original plant. In this activity, students simulate that process and mark the dispersal location on state and local maps. By the end of this activity, students will: Understand why plants have developed so that many seeds are not digested; understand the need for each plant to produce numerous seeds; and understand that there are differences in the metabolism of various animals."
