In this activity, students create a Rain Gauge to place outdoors. This can be used to measure the rate of precipitation in their neighbourhood.
Precipitation is the process occurs when water falls from clouds to the ground. It can happen as rain, snow, sleet, or hail. The rate of precipitation varies seasonally and regionally.
A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologist (scientist who study weather) and hydrologists ( scientists who study water) to gather and measure the amount of liquid precipitation over a predefined area, over a period of time. It is used for determining the depth of precipitation (usually in millimeters ) that occurs over a unit area and thus measuring rainfall amount.
In Vancouver, the rainy season is winter and very little rain falls during the summer. Rain gauges are great tools to use for monitoring changes in precipitation over time. They are used by scientists to predict how much water we will have in stored in our reservoirs and to predict how much water we can use in dryer periods.
