7. Our water barometer Step1: water level is the same Step2: Outside, the water level of the straw is down Step3: near the radiator, the water level of the straw is up
8. How to build and how to use our psycrometer. How to measure indirectly the relative humidity 1 2 3 4 5
9. Calculating relative humidity: temperature of the dry bulb thermometer: 15 ° C wet bulb thermometer temperature: 12 ° C difference (dry bulb - wet bulb): 15 ° C - 12 ° C = 3 ° C Therefore the relative humidity is 71%
10. Finally we have the instruments and we can begin to collect the observations and to record data In our little “WEATHER STATION” we have the thermometer, the hygrometer and the barometer
