Make a rain collector for recording weather


2 litre bottle


Cut around the large bottle about two thirds of the way up. Turn the top upside down and check that it fits into the bottom, like a funnel. Bury the large bottle so that the top is about 5 cm above the ground, in order to prevent large raindrops splashing into the gauge. This will also stop the rain gauge blowing away on windy days. Think about where to put your rain gauge and choose a position in the open, away from trees or buildings.

Check the rain gauge every day, preferably at the same time. Measure the amount of rainfall collected in the small bottle, then empty the water out. It is important to check the rain gauge even if there has been no rainfall. This is because small amounts of dew may accumulate in the bottle, leading to false readings when rain does fall. You also need to check that leaves or spiders have not fallen into the funnel, as this may block.
