First take 20ml of starch solution
Measure out a specific amount of amylase
Different groups used different amounts of amylase
It must be measured out carefully
Then put a couple of drops of iodine in each dip of a spotting tray
Iodine goes black with starch
Once everything is ready
Add the amylase to the starch, mix and start the timer
Keep mixing
And every minute add a drop of two of the mixture to a dip in the spotting tray
Keep going until the iodine does not go black
Then you know the amylase enzyme has turned all of the starch into glucose
This set of results shows that the amylase took between three and four minutes to digest the starch.
The class found that the more amylase you have the quicker digestion occurs.
