Enquiring Minds – AS Level Biology

The Year 11 Biology students did their first AS-practical on biological molecules for the year. During the practical they were presented with five solutions containing different concentrations of starch and sugar. They had to use Iodine solution, Benedict’s reagent and Hydrochloric acid to determine what the contents of each solution was. The results presented an array of different colour changes that provided great excitement to the students.

This is an important first step towards preparing the students for their AS practical exam at the end of Year 12. The experience they gain by handling equipment, planning an investigation and executing the plan, will form a foundation on which to build enquiring minds.
