Polystyrene Laboratory Analysis: A Hands-On Experience for High School Students to Determine the Molecular Weight of Polystyrene Through Spin Casting.

ABSTRACT: Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To bridge the gap between the benefits and drawbacks, this study investigates a method to educate high school students (with no previous experience) about standard chemical laboratory practices. 98 high school students experimented throughout two days to determine the molecular weights and characteristics of various polystyrene samples, essential knowledge for polymer recycling. Students were split into 5 groups so that laboratory usage be organized
