In this lesson, students explore how the structures of seeds enable them to disperse, with a focus on seeds that utilize animal structures to aid in their dispersal. In the activity, Seed Travelers, students develop a model of a furry animal (“fluffadoo”) and then use it to test how far seed models with different structures can travel.

We suggest students work in pairs. Homeschool students can work on their own.
Seed A (pompom) is distributed in Step 7 and Seed B (bean) is distributed in Step 14.
Make sure students have space to hop up and down in place when doing fluffadoo + seed model tests.
Seed A should stay on the fluffadoo the longest. Oftentimes, it can stay attached until the maximum of 15 hops. Seed B should fall off of the fluffadoo almost immediately- usually within 1 or 2 hops.
If Seed A is consistently falling off of a student's fluffadoo within a few hops, we suggest checking: (1) the pompom is being placed where multiple cotton balls touch (rather than on top of a single cotton ball) and (2) the student is “hopping gently” and not shaking their fluffadoo too hard while hopping.
Instead of hopping in place, students can test their fluffadoo + seed by raising and lowering their arms while seated (mimicking the motion of a hopping fluffadoo).
