FRBV26 MSTE SHARE Universal Plastic Detectives

This workshop offered an educational dive into the world of plastic, moving from global environmental consequences to hands-on scientific analysis. It opened with a focus on the Tara Ocean Foundation, a UN Special Observer that conducts scientific expeditions to study marine health. Students were presented with a striking reality: at current rates, plastic will outweigh fish in our oceans by 2050. This highlighted that plastic is not just "litter," but a complex material integrated into almost every aspect of modern life. Students moved from theory to practice by working in small groups to categorize plastic samples based on:

-Physical Properties: Visual and tactile cues like texture, rigidity, and transparency. 

-Recycling Codes: Searching for the numbered triangular symbols that denote the specific plastic "family."

Because environmental plastic fragments often lack labels, students used density-based experiments to identify them. By observing whether a sample sinks or floats in different liquids, they were able to narrow down its chemical identity.

All observations were recorded on a diagram, allowing students to compare results and draw conclusions.

The workshop showed that plastics are not a single uniform material. Their varying chemical properties determine how they travel through the environment, how long they persist, and the specific challenges they pose to recycling and marine life.

The session concluded with a timed challenge to identify a "mystery sample." For each of the three groups, the winners managed to complete the challenge in under 2 minutes. Well done!

Despite some difficulties with English, the students successfully completed the proposed activities, followed the safety rules, and easily navigated the identification flowchart to label the mystery samples. They were able to identify the various samples. This data-driven approach allowed students to understand the specific technical challenges plastics pose to global recycling efforts and their impact on oceans.  Students learnt to interpret symbols, diagrams, and experimental results. They worked effectively in groups, shared roles, and discussed findings.
