    • Comenius Project Weather conditions LaFrançaise, February 2011 COMPREHENSIVE SCHOOL “ M. BUONARROTI” Marina di Carrara Presents
    •  
    • Our tools The rain gauge The windsock The water barometer The psycrometer
      • The rain gauge is an instrument used to measure the amount of rainfall through the height of the deposited water.
      Our rain gauge
      • Material: very light fabric, wire, two rings, a broom, a stick.
      Our windsock
      • The wind
      • Looking at the position of the windsock we can define if the wind is absent or, if present, if it is weak, medium or strong. From the direction that the windsock takes, with the help of a compass, we can determine the wind direction, that is the cardinal point from which it blows and notes are written in the table.
      … and our wind rose
    • 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
    • How to build and how to use our psycrometer. How to measure indirectly the relative humidity 1 2 3 4 5
    • 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%
    • 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
    • Our data: hand made graphs
    • Our data: digital graphs November’sTemperature AVERAGE TEMPERATURE OF NOVEMBER: 14 ° C GIORNI GRADI °C 01/11/2010 16 02/11/2010 16 03/11/2010 15 04/11/2010 17 05/11/2010 16 06/11/2010 17 07/11/2010 15 08/11/2010 16 09/11/2010 13 10/11/2010 12 11/11/2010 15 12/11/2010 15 13/11/2010 15 14/11/2010 17 15/11/2010 18 16/11/2010 18 17/11/2010 14 18/11/2010 10 19/11/2010 17 20/11/2010 13 21/11/2010 14 22/11/2010 13 23/11/2010 12 24/11/2010 13 25/11/2010 11 26/11/2010 9 27/11/2010 9 28/11/2010 10 29/11/2010 14 30/11/2010 12

    • Our laboratory experiments The acid rain The clouds in a jar
      • MATERIAL
      • Papers with universal indicator
      • Distilled water
      • Rainwater
      • Vinegar
      • Hydrochloric acid
      • Bicarbonate
      • Dishwashing liquid
      • Saliva
      • We collected rain water in a clean jar and found the ph using papers with universal indicator.
      • We then compared the colour of the paper that was submerged in rainwater with the one that the paper takes in distilled water.
      Acid rain
      • We repeat with the vinegar, dilute hydrochloric acid, bicarbonate, dishwashing liquid, saliva.
    • We have different ph values. The more acidic substance is the hydrochloric acid, the less acidic one is the bicarbonate. Table sample Universal paper colour Ph value Distilled water yellow 7 Rain water Light green 6 Vinegard Red 3 Hydrochloric acid Deep red 1 Bicarbonate Light blue 12 Dishwashing liquid Yellow 7 Saliva Light green 6
    • - damages to the trees that get sick and dry - acceleration of the melting of ice - pollution of the lakes, killing animals and plants that inhabit them - attacks and damages to the marble monuments 1908 1968 Adverse effects of the acid rain on the environment
    • Could also it occur in Carrara? What will happen to our old cathedral, completely covered with fine white marble from the quarries? The rose window in 2011 … The rose window 50 years later
    • Three special events
    • November begins with bad weather conditions. Heavy rains and landslides occur in and around Carrara
    • It snows today! The snow, 2010 – December 17th
    • … some unusual landscapes
      • January 4 th 2011, 9.20 a.m. – our solar eclipse
