πŸ’¨Wind

πŸ’¨ What is Wind?

Wind is moving air. We cannot see it, but we can feel it.
We can hear it blowing through tree branches or see it move things like clothes on a line.

🧭 Wind Has Direction

Wind doesn't just blow anyhow—it has a direction.

πŸ‘‰ We can tell which way the wind is blowing by:

  • Watching smoke from a fire

  • Dropping dry soil and seeing where it goes

  • Looking at clothes or flags blowing in the wind

  1. πŸ”₯ Watch smoke from a fire or chimney

  2. ✋ Drop dry soil from your hand

  3. 🧺 Watch clothes or flags blowing

  4. 🧭 Use a compass or a wind vane

πŸ› ️ What is a Wind Vane?

A wind vane is a tool used to show the direction from which the wind is blowing.

🧭 It uses the compass points: North, South, East, West.
The arrow on the vane points where the wind comes from.
