In the framework of OrvietoScience2025, students from IIS Majorana – Maitani actively participated in hands-on laboratory activities under the guidance of their teachers, utilizing protocols developed by the National Research Council of Italy (CNR) as part of the REMEDIES for Ocean program. These training sessions focused on the pressing issue of microplastic pollution and provided students with valuable scientific skills and awareness of marine contamination.
OrvietoScience2925: Fostering Scientific Literacy
OrvietoScience2925 is an annual event that brings together students, researchers, and educators to explore contemporary scientific challenges through conferences, hands-on activities, and discussions. The initiative fosters scientific literacy and encourages young minds to engage with pressing environmental and technological issues. The program culminates in a final conference, where participants share their findings and experiences.
Hands-on Learning: Investigating Microplastic Pollution
As part of the REMEDIES initiative, CNR designed two educational laboratory activities focusing on microplastic contamination from textiles and marine organisms:
1️⃣ Microplastics Released from Textiles During Washing
This laboratory focused on measuring the quantity and size of synthetic microfibers released from textiles during a standard household wash. Students collected water from a washing machine cycle using synthetic fabric and passed it through sieves with different pore sizes. The recovered microfibers were then dried, weighed, and analyzed under a microscope to determine their length and diameter. The activity highlighted the significant role of synthetic textiles in microplastic pollution and the impact of everyday washing habits on aquatic environments.
2️⃣ Microplastic Contamination in Mussels
The second experiment examined mussels, both as bioindicators of marine contamination and as a potential risk for human consumption, since they are eaten whole. Students dissected mussel samples and treated them with potassium hydroxide (KOH) to digest organic material. The samples were then placed in an oven at 45°C overnight before undergoing density separation to isolate microplastics present in the tissues. After filtration, the recovered microplastics were classified and counted using microscopy.
These practical sessions provided students with first-hand experience in environmental research methodologies, reinforcing their understanding of microplastic pollution and its implications for marine life and human health.
Science in Action: Empowering the Next Generation
By engaging students in real-world environmental research, these REMEDIES microplastic laboratories successfully combined education with action. The students not only developed scientific skills but also gained awareness of the impact of plastic pollution, inspiring them to become future advocates for sustainable solutions.
The OrvietoScience2925 final conference marks the culmination of these activities, offering students the opportunity to present their work and engage with experts in the field. You can find more details about the event’s program here: OrvietoScience2925 Final Conference.
