Children will learn all about weather in their science classes. To enhance learning about weather, children can learn how to create instruments to tell them more specifics about the weather. A wind vane can be created by the kids to determine the direction the wind is coming from. If a storm is approaching, the children will be able to determine the direction of that storm based on the direction of the wind.
Cut out the shape of an arrow from a sheet of cardstock. The arrow must be 5cm in length. Then cut out the tail of the arrow. The tail must be 7cm in length. Use a metric ruler to get the measurements exact.
Cut a slit in both ends of your straw. Slide your arrow head in one end, and your arrow tail in the other. If you are afraid they won't stay, you can add a little glue.
Hold a pencil so that its point is facing down. Place the straw over the eraser part of the pencil. Make sure the middle of the straw is over the eraser and then press a push pin down through the straw and into the eraser. Make sure there is a little gap in between the straw and the eraser so that the straw can spin easily.
Build a mound out of some modelling clay. Stick the point of the pencil down into the centre of the mound. Go far enough that the homemade wind vane won't blow over.
Place your homemade wind vane on a paper plate. Label each side of the paper plate with a marker. You should have north, south, east, and west in their respective places.
Take the wind vane outside and note which direction the wind is blowing.
You may need a compass to determine which way is north, south, east, and west.
