Vitamin C Testing
Out of Print: Available as a free download in PDF format.
Written by Jacqueline Barber
This guide is a stimulating introduction to
chemistry experiments and nutrition. Students enter the realm of
consumer science as they use chemistry to evaluate various juices,
learning the drop-by-drop technique of titration and developing
skills in comparison, data collection, calculation, and graphing.
Using a simple chemical test using a vitamin C indicator to compare
the vitamin content of different juices, students pool their results
and create graphs to represent them. They study the effects of environment,
storage, and temperature on vitamin content, and assess the nutritional
value of the beverages they drink.
This unit emphasizes everyday materials, but the indicator chemical
and plastic vials for experimentation must be acquired separately.
The book provides resources for obtaining those items, as well as
thorough guidance in setting up all the experiments.
Time: Four 45-minute sessions plus follow-up sessions.
