Here's a way you can observe the wind in your yard,
playground, neighborhood, or park.
The wind flows around every tree, building, person, and thing. It flows every where. It goes up and down, sideways - it spins and twirls. You can look for the places it goes the fastest, and the places where the air flow is squeezed.
3. Make a small hoop with a handle out of the twisty ties, dip it in some soapy water to make bubbles. (Or you can get a special bubble kit at the store.) The bubbles will follow the wind, and you can follow the bubbles around your yard.
Think about what you can see.
Where are the longest lines (the fastest bunch o' bubbles)?
What are they near?
What's the wind direction?
Which way are the clouds moving?
