In this experiment , we aim to provide an understanding about the concepts of adaptation through a series of tests . This involves using our different senses to perceive changes in an environment , and how we 'll be able to adapt to these changes

In the first experiment , the sense that we are going to use is the sense of taste . Through this test , we 'll determine how we adapt to changes in what we taste or basically what we eat . By mixing sugar into

water , we create a sweet substance which we 're going to use for the taste test . We also need fresh water in to tell any differences afterwards . What I did was to take a sip of sugar water and let it stay in my mouth for some time , until it tastes less sweet . It took several seconds until it tasted less sweet , and afterwards I took a sip from the cup containing fresh water . The surprising part was that the fresh water tasted doesn 't have any taste in it at all . I know water supposedly has no taste , but with the experiment , it tasted stale

In the next test , the sense that will be used is our tactile sense mainly the skin 's perception of temperature . Through this test , we 'll determine how we adopt to the changes of temperature in our environment We prepare three bowls with tap water of varying temperature . One is hot (but not painfully so , another is very cold , and the other is a mixture of the hot and cold tap water . What I did was to submerge my left hand in the hot tap water and my right hand on the cold tap water . I let it stay there for three minutes , and afterwards I placed both my hands in the bowl containing the mixture of hot and cold tap water . I took not of what I felt in the experiment

Upon placing my both my hands in the mixture of water , I noticed that my left (which was previously submerged on the hot one ) felt cold until it slowly changes back to the temperature of the water mixture . Same goes for my right hand , which felt warm when I submerged it in the mixture until it slowly changed back to the temperature of the water mixture . The skin 's receptor was not able to perceive any changes in the temperature in the water

The final test was again on the tactile sense , wherein we have to rub our index finger into a sand and rate its coarseness from 1 to 7 where 1 is very soft , and 7 is very coarse . When I rubbed my index finger to the sand , my initial rating was that it 's 7 , since I felt that it was very coarse to touch . When I rubbed my index finger on the sand for a second time , it felt a little different . It 's...
