Is it windy? Which direction is the wind coming from? How can you tell?
Knowing which way the wind is blowing is an important yet often overlooked piece of information. Wind plays a role in many things we do and you’ll know that’s true if you’ve ever biked into a strong head wind!
Connect with Nature:
- Let’s build a wind vane for your weather station!
- Trace a triangle AND a rectangle with a marker onto your plastic lid. Both shapes should take up most of the space on the lid. Cut out each shape from the lid.
- Cut a 1/4” slit into each end of the straw, making sure the slits are aligned with each other. Slide your plastic triangle into one of the slits and your rectangle into the other. Secure to the straw with a dab of glue.
- Once dry, push the pin through the exact middle of the straw.
- Now, push the sharp end of the pin into the flat end of the skewer (or the eraser-end of a pencil). Place the skewer (or pencil) into the ground somewhere where you can easily see it outdoors.
- Use rocks to mark the directions around your weather vane, so you will know which direction the wind is coming from. Write the directions on your rock with a marker (North, South, East and West)—one per rock. Ask an adult for help identifying where to place the rocks around your vane in the correct location (North, South, East, West).
- Which direction is the wind coming from today? The arrow points toward where the wind comes from. Record this in your weather journal!
