Vitamin+C

Students were very interested. They were aware of the possible outcomes. It seems they found the experiment relevant. Maybe we should find more nutrition related experiments.

They also showed interest in the details of the rationale behind the vitamin C determination technique. Again, future activities might involve similar chemical reactions that are interesting and have a certain complexity.

Some students had real difficulty with promotions. This brings up the possibility of including a proportion activity in the future.

Data tables also showed a pervasive neatness problem. Nothing new. In the future we could have an activity where an experiment is described and the results are given. The students would concentrate on writing the report and we could concentrate on neatness. Another option is to give the report to an instructor notin the science field and aske them to give an "appearance" grade that would form part of the overall lab grade.

We only did three juices: two types of orange juice and a grape juice.
