CfE Higher - Researching Chemistry 2016

This is my attempt to walk the fine line between 'supporting' and 'spoon-feeding' pupils involved in researching Antioxidants/Vitamin C.

The intention is to concentrate on Vitamin C for the Practical part of the Researching Chemistry and, therefore, Vitamin C will be the focus of the 'Short Report' which is Internally assessed. There is the option of expanding into a more general look at antioxidants for the Assignment Report - externally assessed by SQA.

Wherever possible, I will keep a copy of the relevant document on this website but you should use the 'Web Link' as your reference. I will also provide a link to the core 'Web Site' to enable you to investigate further to help decide on Validity & Reliability.

Practical Videos


The first Video demonstrates a simple 'kitchen' experiment devised by the RSC for the 2013 Global Experiment. It could be 'upgraded' by using more accurate Lab equipment and would be an interesting Planning challenge. The second Video is an excellent reminder of how to set up and perform a Titration.

Other Useful Documents


Researching Chemistry was introduced as part of the Revised Higher a few years ago, though only as an Internal Assessment. A number of the guides produced by LTS and SSERC are still valid but may be 'out of date' in terms of latest SQA regulations. Refer always to the latest Candidate Guides.

The SSERC Vitamin C document is 'work in progress' and has sections that refer to Biofuels (one of the other options for Researching Chemistry) and even refers to Physics (which I believe is a minor branch of Science sometimes taught in some Scottish Schools). However, much of the information is still very useful and I will update the document as and when possible.
