Students  performed an activity where they mixed the starch solution with iodine solution . Starch turns blue with iodine .Then students mixed the cold starch solution with saliva and then added iodine solution to it .Starch turned blue but as the starch turns into sugars by action of saliva the blue color fades away  and turns trabsparent .

Students reach to conclusion that enzymes present in saliva breakdown starch into sugars .
