Units for measuring the temperature

During the last science session students learnt about units for measuring the temperature: Centigrade and Fahrenheit. 1-We placed a graduated thermometer in class(contains both units C & F).Students recorded the temperature daily in both units. 2-Students surffed the net to find that countries like Germany,Russia,France,and United States are using Fahrenheit scale. 3- We learnt that 0 C = 32 F, 10 C = 50 F,and that water boils at 212 degree F and freezes at 32 degree F. 4- Finally students drew their own thermometers, and they graduated it in both units.
