Make a Weather Vane

A weather vane will show you the direction the wind is moving. It's a great addition to your DIY weather station.

Compass (or a compass app)
Clay
Cardstock or construction paper
Straw
Scissors
Permanent marker
Sharp pencil with a good eraser

On your cardboard or plate (if using a plate, flip it upside down) write North/East/South/West and draw lines to represent those quadrants.
Cut and arrow head (triangle) and tail (square) out of the construction paper/card stock. Cut small notches in each end of your straw and insert the arrow into one and tail into the other. It's best to tape or glue those pieces into place.
Put a glob of clay in the center of your plate/cardboard. Stick the sharp end of your pencil into the clay and wrap the clay tightly around it to keep it in place.
Using the pin or thumbtack skewer the center of the straw so the pin goes all the way through it. Then stick the pin into the eraser, making sure it is loose enough the arrow can still spin.
It's time to set your weather vane outside! Find a place where the wind won't be blocked by a building or anything. Then use your compass to find the right orientation for your directions.
