Use this investigation to help students understand the role of chemistry in cooking, and appreciate that chemistry is all around them. The topics involved relate well to their study of natural organic compounds, and the worksheet links to the study of acids, proteins, amino acids and enzymes.

This activity will improve their skills in data analysis and drawing conclusions. It also provides experience of experiments in unfamiliar contexts. 

You should use this investigation worksheet alongside the Education in Chemistry article, What’s cooking?
