Our Grade 12 Physical Science learners conducted an interesting and educational practical experiment on Wednesday, 11 March, during which they prepared esters. This practical forms part of their curriculum and allows learners to see how theory works in practice.
Esters are organic compounds that are particularly known for their distinctive and pleasant aromas. Many of the aromas we associate with fruit – such as banana, pineapple or apple – are caused by different esters.
During this practical, the learners used different chemical substances to form esters. Through these reactions, they were able to experience how different combinations of substances produce different smells. This type of practical work helps learners to develop a deeper understanding of organic chemistry, as they can see and smell first-hand how chemical reactions occur. This makes the learning process not only more interesting but also more meaningful.
The Grade 12s really enjoyed the practical and gained valuable experience that will help them in their preparation for the National Senior Certificate examination later this year.
