  1. The Study of Flying Seeds Koki MIZUI Assei SANZEN

  2. Motivation We chose this topic because we are interested in flying things. Now, air planes fly in the sky but they consume a large amount of fuel. The seeds of Alsomitramacrocarpa have wings and they can fly very far. They don't need their own force to move.

  3. About AlsomitraMacrocarpa big fruit • thin feather

  4. Experiment We prepared some models from styrofoam.

  5. We named them: Ks, Ms, and As (s means styrofoam) We dropped each model 10 times from 2.45m high.

  6. How to drop

  7. Type”a”Falling Large ; Flying Small ; Falling

  8. Type ”b” Falling

  9. Type ”c” Falling

  10. Type ”d” Falling

  11. Type ”E” Flying

  12. Type ”F” Flying

  13. Type ”G” Flying

  14. Type ”h” Falling

  15. Type ” j ”Falling

  16. Result 1

  18. Consideration ①We can classify these models under two types. Model K & A → Straight flying Type “e” Model M → Wave flying Type “g” ②We should consider how to keep these models ; if they change their shape , their way of flying will change.

  19. Hopes ① We want to find what changes the way of flying between Type” e ” and Type” g ”. ②We want to find the relationship between the biological and physical mechanisms of these seeds.

  20. Thank you for listening.
