Temperature


              Temperature is a
              degree of hotness
              or coldness the
              can be measured
              using a
              thermometer.
       There is a relation between

       altitude and temperature.
Hypothesis
       My plan for this experiment




                                       Navigation
       is to find out and study how
       altitude affects temperature.

               The sun heats the earth and as the
               ground absorbs the heat from the sun
               the air above the ground conducts the
               warmth and that is how the air gets it
               heat. The air temperature depends on
               how warm the earth is: if the ground
               temperature is warm the air
Introduction

               temperature will therefore increase.

               Regarding this information, the higher
               up the air is, the cooler the air
               becomes because it means that the air
               is further away from the heat source.
               So there should be a difference in the
               air temperature, between how high up
               and how low down the air is, but how
               big will this difference be.

           I will be
           conducting my
           experiment in
           Switzerland as
           Switzerland is
           home to many
           great mountains
           such as the
Location



           Matterhorn. This
           will enable me to
           get high above sea
           level so this will
           be the ideal place
           to do my
           experiment.

                                    • The data I will need is the
                                      temperatures from
                                      multiple stops down the
                                      descent. I will ski from
                                      Gornergrat at 3090m were

         from here.                   intervals of 100m. I will
                                      also take my position on a
                                      GPS. I will then take my

                       And finish     I will be able to see if
                       here.          altitude affects
                                      temperature.

 • From my previous experience I have discovered that the
   higher up an incline I travel the colder it gets. This is clearly
   evident because snow only settles at the top of mountains
   and that shows it is below the freezing point of water at the
   top of a mountains but not at the bottom.

             To conclude I think this experiment was a success as I
             achieved positive results which proved my prediction to
             be correct. This experiment has proved that altitude
             does affect temperature quite severely. Overall I think
             the experiment has been a great success.
Conclusion




                                 Gornergrat
                                                                             Navigation
             If I was to do this experiment again I would probably change aspects of it
             to get more accurate results. Instead of skiing down the mountainside and
             taking readings as I go I would place thermometers all the way down one
             side of the mountain and take the readings all at once. This will ensure that
             I am only getting readings from one side of the mountain instead of
             changing sides between readings. Furthermore when I did the experiment
             the sun was dipping in and out of clouds and the temperature was
             therefore dropping between readings and so taking all the readings at once
Evaluation

             would make a fair test. Otherwise I think I made this test as fair as it
             possibly could be.
