Here's a video from Howcast that shows you how to make one. Another instrument that shows you the direction of the wind is a weather vane or weather cock. If you want to see which way the wind is blowing, here are video instructions to make a simple windsock from items you have around the house. That's because the land and the sea heat up and cool down at different rates.įind lots more information on wind and weather on this link from Weather Wiz Kids. Weather vanes are simple instruments that show the direction of wind, but not the speed. Even locally, notice how wind changes direction in the morning and evening when you are near the seaside. The wind in Ireland changes direction all the time, moving from areas of high air pressure to areas of low pressure.
In Ireland when the wind comes from the south we get warmer weather, and if the wind comes from the north it gets cold.
These assessments are made depending on which hemisphere (north or south) the weather vane is located in and by the wind direction. However, there are a few general assessments that can be made through using a weather vane by itself. They can use a weather vane as a jumping off point to explore the history of the decorative symbols used to top them or delve more deeply into the physics of wind and barometric pressure. Most often, they are used alongside a barometer. Weather vanes make good first science projects for children to use to learn to measure and understand the world around them. Our weather depends on which way the wind is blowing. Weather vanes can be used to aid in forecasting weather.
Have you ever seen a windsock at an airport or by the side of a sports pitch? It shows you very clearly which direction the wind is coming from, and how fast it is blowing.
