Seed Dispersal Challenge

Plants can't walk — so they've evolved amazing tricks. Study helicopter samaras and sticky hitchhikers, then engineer your own seed dispersal method using only natural materials.

What You'll Need

  • A variety of seeds: dandelion puffs, maple samaras (helicopters), acorns, any sticky burr you can find
  • A pair of thick athletic socks for the Sock Walk
  • A measuring tape or long stick
  • A notebook and pencil

How To Do It

  1. Collect seeds — dandelion puffs (wind), maple samaras (wind + spin), burdock burrs (animal fur), acorns (gravity + squirrels). Grab anything interesting you find.
  2. Study each design — drop each seed from above your head and observe how it moves. Does it fly? Roll? Spin? Stick? Sketch it.
  3. The engineering challenge — choose one seed and try to make it travel FURTHER using only natural materials. Extra leaves as wings? A dandelion fluff parachute? Measure the distance each version travels.
  4. The Louisiana Sock Walk — pull a thick athletic sock over one shoe and walk through an unmowed area for 5 minutes. Remove and count every seed stuck to it. You've become a seed dispersal animal!

Grandma Says

Before the Sock Walk, ask everyone to guess how many seeds they'll collect. Most guess 5 or 10. The real number is usually 30 to 80. That moment of counting is the real lesson.
