This activity challenges you to measure wind speed and direction simply by blowing bubbles.
What is wind and why is it important?
Wind is the movement of air in the atmosphere caused by differences in air temperature and pressure, as well as the Earth's spin. The wind is an important part of the weather system. It also helps plants to reproduce.
ACTIVITY – From sailing to drying our clothes, there are many ways we make use of the wind. How many can you think of?
Measuring the wind – how and why?
Wind can vary from a gentle breeze to a dangerous hurricane force. The strength of wind is often recorded using the Beaufort scale. Knowing the direction and strength of the wind helps scientists predict the weather – from a rainy day in Manchester to a potential hurricane in Central America.
Create your own weather station
Measure wind, air pressure, rainfall and more with a homemade weather station. All you need is a few household items.
Make your own wind vane
Have you spotted a wind vane on a roof or tower?
It's a simple way to tell which direction the wind is coming from.

Using the wind to reproduce
Many plants use the wind to scatter their seeds over a wide area.
Sycamore trees have a seed case that is shaped so that it spins like helicopter blades. Other plants, such as Dandelions, have very light seeds so they travel longer distances.
ACTIVITY – Can you find more plants that use the wind to disperse their seeds?
Take a look at the different trees, flowers and grasses outside. Which plants do you think use the wind to disperse their seeds?
Try dropping different seeds to compare how they fall. Which seeds are likely to travel longer distances?
