• Rain gauge
• The rain gauge is kept in an open space in the weather station from above. Its raised to avoid splashes from entering into the gauge.
• The water collected is emptied into the measuring cylinder every 24hrs.
• Take readings on the measuring cylinder.
• This cylinder is graduated in mm and the level the water emptied reaches gives us the reading amount of rainfall for the day.
• Record the readings and interpret.
• A maximum and minimum thermometer
• When the temperature rises, alcohol in the left hand column expands and pushes the mercury column and maximum temperature is read.
• When the temperature rises, alcohol in the left hand column contracts and pulls the index along the tube and the minimum temperature is read from the upper end of the index.
• After recording the reading, the thermometer is reset using a magnet.
• Interpret the readings.
