Keep wind equal
Compare two structures at the same wind strength.
Seed Dispersal Journey
Compare how fluffy, winged and heavy seed structures travel in a simple wind model.
Grades 2–5 · Biology
Your goal
Release the fluffy parachute seed with wind strength 1. Observe its landing distance.
Reduced motion is on. The controls still update the scene.
Choose an existing seed structure and a wind strength, then release it.
Seeds already have their structures before dispersal. Wind carries some shapes more easily than others. This fixed-height comparison holds other conditions equal. Real travel also depends on gusts, release height, seed mass and obstacles. Landing does not guarantee germination.

Learn with Seed Dispersal Journey
Seed Dispersal Journey helps elementary students connect seed structures with movement through air. Choose a fluffy parachute, a wing or a heavy seed, set the wind strength, and release the seed from the parent plant. The landing marker shows an illustrative distance on a shared scale so children can compare structures under matching conditions. Guided goals encourage repeated trials with controlled choices. The model keeps release height constant and explains that real seed travel and successful germination depend on many other conditions.
What to look for
Try still air
Set wind to zero and observe the lack of sideways travel.
Read the landing scale
A larger number means farther travel in this model.
For teachers and curious learners
Discover how existing seed structures affect wind dispersal. Ask students to predict what will happen, change one setting, and explain what they observe. Learn gives a starting point. Practice and Challenge offer new goals with the same scene.
Fixed-height deterministic comparison of relative travel. Model spaces are not real distances, and landing does not predict germination.
