1) Draw a triangle onto thick paper, then cut it out. Use a ruler to draw a 4 cm (1.6 in) line onto your paper to make a base for a triangle. Next, place your ruler perpendicular to the line at the halfway mark and trace a 5 cm (2.0 in) line to make an upside down "T." Then, use your ruler to draw lines connecting the top of the upside down "T" to each side of the base line. Finally, cut out the triangle with a pair of scissors.[1]
For instance, you might use a manila folder, index cards, poster board, cardstock paper, or an old cereal box.
2) Draw a square onto thick paper, then cut it out. Make your square about 7 cm (2.8 in) long on each side, with your sides roughly even. It’s okay to estimate the measurements, but it’s best to draw your square larger than the triangle. Then, use a pair of scissors to cut out the square, which will be the other end of your arrow.
3) Cut a 1 cm (0.39 in) slit in each end of a drinking straw. Hold your scissors parallel to the straw. Then cut an even slit through each side so that your arrow pieces will slide onto the ends of the straw. Although they don’t need to be exact, your slits should be about 1 centimetre (0.39 in) long and directly opposite each other so you can stick the paper in them.
4) Stick the triangle and square into the slots on the straw to make an arrow. Put the triangle on one end of the straw with the point facing out. Then, slide the square onto the other end. When you’re finished, your straw will look like an arrow.
5) Put a pin through the center of the straw and into the pencil eraser. Find the center of the straw, then push the point of a straight pin through it. Keep pushing until the pin exits the bottom of the straw. Then, push the point of the pin into the center of your pencil’s eraser.
6) Use a big piece of soft clay as a quick and easy base. Roll the piece of clay into a ball. Then, press the point of your pencil into the clay. The clay will act as a weight to keep your wind vane in place.
7) Write the 4 primary and 4 intermediate directions on a paper plate. Write North (N) at the top of the plate. Then, go clockwise and write East (E) on the right side, South (S) on the bottom, and West (W) on the left side. If you’d like, add Northeast (NE) halfway between North and East, Southeast (SE) halfway between East and South, Southwest (SW) halfway between South and West, and Northwest (NW) halfway between North and West.
8) Push the clay ball into the center of plate to keep it in place. Press the bottom of the clay ball onto the center of the plate. Then, use your fingers to push down the edges of the clay to root it in place. This will keep your wind vane in the center of your plate while you use it to measure the direction of the wind.
9) Take your wind vane outside to find the direction the wind is blowing. Use your compass to find the direction of North, then point the North side of your weather vane in the correct direction. Stand away from walls and large objects that could block the wind. Next, watch for your wind vane to start spinning. It will point in the direction the wind is coming from.
