## Standing in the Rain, Teaching: Video

Rain gauges measure rainfall by collecting a small sample and measuring how deep the water is. The trouble is, we are interested in very small units – in the metric system, rainfall is measured in millimetres/millimeters. How can you accurately measure such small amounts?

How can we use everyday examples to teach measurement?

Watch the video: I explain how a rain gauge amplifies the depth of water collected to make it easier to measure.
