Thursday: Design a wind seed

Rocket drops a crumpled paper ball. Plop! It falls straight down.

"Seeds need to travel far," he groans.

Raven picks up a maple seed. "What do you notice about its shape?"

Nova spins in a circle. "Hint: wings help it twirl."

"Let us build a spinner!" Rocket says.

Shape helps seeds travel

A seed’s shape helps it do its job.

Maple seeds have wings that help them spin as they fall.

Light seeds move easily in the air.

You can copy a seed’s shape to build a model.

  1. Cut a strip of paper about as long as your hand.
  2. Cut a short slit down the middle of the top half.
  3. Fold the two flaps opposite ways, like wings.
  4. Fold up the bottom and add a paper clip.
  5. Drop it from your shoulder and watch it spin.
Safety first
A grown-up helps with scissors.
Drop your spinner while standing on the floor, not a chair.
