First and foremost, we would like to express our deepest gratitude to our Investigative Sciences Studies teacher in charge, Ms Kassandra Lim, for her guidance and constant encouragement throughout our learning journey this term. She had pushed us to try our best and to develop as independent critical thinkers while still providing the support needed.
We would especially like to thank Ms Su Ya Hui, the laboratory manager, for providing us the equipment and materials needed, as well as her thoughtful and useful suggestions that aided us in this experiment. We appreciate her patience and kindness towards us.
