We previously developed a plastic sorting activity for high school students. In that activity, several tools were provided to separate plastic waste materials based on their physical properties while considering the time and cost for each separation step. Here, we aimed to understand the impact of this activity on the awareness of and learning about plastic sorting in a younger age group (8 to 11 years old) and explored how parental involvement influenced students' interest in the topic. The activity was part of the STEM Zone Saturday program at the University of Houston. Pre- and post-evaluations were used to assess students' understanding of plastic sorting and overall experiences. While some insights into plastic sorting were derived from previous experiences, the activity improved awareness among students, particularly regarding sorting based on physical properties. The involvement of parents encouraged exploration, discovery, and enjoyment. These findings underscore the importance of early education and community engagement in fostering sustainable practices and advancing toward a circular economy.
