Wind sock experiment

Build a simple wind sock and use it to observe whether wind is present, how strong it is, and which way it blows.

You cannot see air, but you can see what it does. A wind sock is a simple tool, like a bag or streamers on a stick, that catches moving air and shows you it is there. When the wind sock moves a lot, the wind is strong. When it barely moves, the wind is gentle.

A wind sock can also show direction. If it points away from the house, the wind is blowing from the house toward wherever it points.

📋 For the teacher
Teach it (10–15 min):
  • Help build the wind sock together: streamers, a plastic bag, or ribbon taped to a stick or straw.
  • Take it outside and hold it up together, away from your bodies so you do not create fake wind.
  • Describe the strength together using words like calm, gentle breeze, or strong wind.
  • Point out that wind and cold are different: check the temperature and the wind sock separately.
Talk about it:
  • Which way did your wind sock point?
  • Was the wind strong or gentle today?
  • How did you know wind was there without seeing the air itself?

Mastery looks like: They use a simple wind sock to describe whether wind is present, roughly how strong it is, and which way it blows.

Common stumbles: Confusing windy with cold, since they often happen together but are not the same thing; mistaking their own movement for real wind.
