What Makes Things Blow Away?

Use safe, everyday objects to notice what moving air can do.

One idea to carry along

Wind is air in motion. Moving air can push on objects, but different objects move in different ways.

Begin with a paper scrap, a soft cloth, and a small book or other stable object. In a safe, clear place, children make a prediction before a grown-up creates a gentle breeze with a piece of cardboard or a handheld fan.

Try it together

  1. Choose safe objects. Use light, harmless objects and one heavier, stable object. Keep faces and loose hair away from fans.
  2. Make a prediction. Ask which object will move first when air starts moving.
  3. Try a gentle breeze. A grown-up can wave a piece of cardboard from a distance or use a gentle handheld fan setting.
  4. Notice and compare. Which object moved, slid, fluttered, or stayed put? Repeat only if it remains fun and safe.

Keep the conversation going

Point outside at a flag, leaf, or scarf and ask: “What tells us the air is moving?”

Grown-up note

Use only safe, lightweight objects. Do not use a fan around water, on a high setting, or where it could reach a child’s face or hair.
