After we have done with our
experiment, we know that teamwork play an important role in any group project
or experiment. Without a good cooperation, experiment or group cannot be done.
In this experiment, there are some unavoidable mistake that occur. It is may be
due to how we handle our material and apparatus. In the next experiment, I will
try as much as I can to handle the apparatus and material properly to minimize
the error. Then, this experiment really make me a very patience person. This
lab project takes along time to finish. It takes us so much time that we
expected. We just bear with it until we finish all of the lab project.

After
we finished our lab work, we need to submit our laboratory report and write
reflection on what we have learned throughout the session. This is my genuine
reflective writing on what I have gained during the class. I believed that
reflective writing is used to increase understanding and analytical ability.
Teachers or lecturers are able evaluate the experimental work throughout their
students’ written reflections. Reflection also can indicate my level of
knowledge associated with the experimentation.
In
this experiment, there are some errors in our results. We believed that it due
to us did not handle the materials and apparatus correctly. In next experiment,
we will make sure to handle the materials carefully and trying minimize the
errors occur. I hope that we can learn from our mistakes and make an
improvement in the next experiment work.
Due
to the failure that we obtained in some of our results, we can learn that not
all experiments will be a success. There will be some errors in the experiment
no matter it is a little or much because we human are not perfect. But we can
always learn from our mistakes, and take it as a lesson learnt for us to work
better in the future.
In
this experiment, I would to thanks my groupmates for their cooperation
throughout the lab work and being helpful.

Assalamualikum and hello everyone, today we are doing
the laboratory project about enzyme. The purpose of this experiment to look at
the effect of amylase on a starchy food. For this experiment, we use rice as
our sample to test the presence of starch. First, we make a 3 model guts make
of visking tube and tie a knot in one end of the visking tube. Three visking
tube than be placed into three boiling tube and be added with three different
type of solution which is water, amylase and treaded amylase. The boiling tubes
containing the model gut placed into beaker contained water at 37 0C.
Then the incubation time was set into 30 minutes. Then every 5 minutes, the
solution from the model guts been test with iodine and benedict solution. The
visking tube play the role as the wall of small intestine. To look at the
present of the starch. We also test the rice with iodine by added one drop of
the iodine into the rice. Besides, we also test the rice with the benedict
solution, we put some of the rice into test tube and then add 2 mL of distilled
water and benedict solution. Then the test tube been place into the beaker
contained water at 37 0C.From this experiment, it show that when the
presence of the starch the food sample will change into blue black colour when
been test with iodine solution. This experiment taught me about the effect of
amylase on the starchy food and also how to identify the presence of starch in
food.
Thank you.
