Chemical engineering is rarely encountered before higher-level education in the U.S. or in Europe, leaving prospective students unaware of what an applied chemistry or chemical engineering degree entails. In this lab experiment, we report the implementation of a three-day course to showcase chemical engineering principles for 16-17 year olds studying chemistry and mathematics at high school level. The course focused on simple mass and energy balances and reaction engineering and aided the students in making an informed decision toward what to study at university. In addition, we introduced sustainability and renewable energy concepts in a laboratory environment.
