Interactive Primary Newsletter 36 Sun and Wind (Renewable Energy Special)

Finding the direction of the wind Pupils can use a compass to find North and can then mark out a compass rose (opposite) on the ground. When they stand in the centre with their windsock they will be able work out in which direction the wind is blowing (Fig.5). A word of caution! Winds are named after the direction from which they have come, therefore, if the windsock is blowing over the East marking on the ground the wind is in fact blowing from the West – the West wind doth blow!
