Good afternoon,
Sorry I’m not in today, I’m moving house! Some of you have
now finished your BTEC work and should be congratulated on your efforts and
some of you still have some things to do, which we shall tackle when I’m back
on Thursday.
Today’s lesson:
You will need to produce a plan for an experiment and
present it as a scientific report. We will carry out the practical next lesson
and will then come back to the IT rooms to write it up.
You need to plan a piece of practical work to investigate how
cooking peppers changes the amount of vitamin C they have in them.
You will need to complete a report and answer the following
questions:
Title
Introduction
-

-
What is DC-PIP and how do you use it to test for
vitamin C?
Method
