Professionally, my best STEM moment in my rewarding clinical biotechnology career was my contribution to research producing a molecule that helps destroy cancer.
But personally, it is when I walk into primary school to excited students yelling “Yay, today is science!”. It is the level of satisfaction gained from helping students discover an enthusiastic curiosity of critical investigation. It is seeing them understand the role and effect of atoms on the periodic table in wind, water, light and energy to create and make things happen, with everything dependent on everything else in constant cycles. It is helping them see that everyone is a scientist in some way!
