Tracing the Journey of a Plastic Fragment: A Material Diary Tutorial for CCGL9076

Introduction: Why Material Diaries Matter in 2026

In June 2026, as global attention turns to plastic pollution during World Oceans Week, the assignment Material Diaries in CCGL9076 Material Matters feels more relevant than ever. Every day, we interact with polymers—from the smartphone in your hand to the packaging of your lunch. But how often do we pause to ask: Where did this material come from? What journey did it take to reach me? This tutorial will help you craft a thoughtful material diary that traces a polymer fragment from its source to its final resting place, blending research, personal narrative, and visual storytelling.

Step 1: Sourcing Your Polymer Samples

The first step is to find three distinct polymer fragments from a local environment—beaches, streams, rocky shores, or mangrove forests. In Hong Kong, for instance, you might collect a weathered piece of Styrofoam from a beach or a fragment of fishing net from a rocky shore. Remember: do not purchase materials; respect the habitat and collect only what is already there. Each sample should be 5–20 cm in size and vary in composition, color, and decay level.

Documenting the Find

Before picking up the fragment, take a bird's-eye view photograph that is steady, well-lit, and free of shadows or people. Use your smartphone's GPS to record georeferenced coordinates. This documentation is crucial for linking your material to its place of origin.

Step 2: Researching the Material's Story

Once you have your samples, conduct desktop research to understand each polymer's properties, production processes, and environmental impact. For example, if you found a piece of expanded polystyrene (EPS), learn about its extraction from petroleum, its use in packaging, and its slow decomposition rate. Connect this to current trends: in 2026, many brands are phasing out EPS due to bans in several countries. Your research should answer questions like: How is this material made? What is its typical lifespan? How does it affect ecosystems?

Step 3: Writing a 300-Word Narrative Essay

Your essay should not be a dry research report. Instead, tell the story of the material's journey. Imagine you are the plastic fragment: I was born in a factory in China, filled with bubble tea, then discarded on a street in Hong Kong. Rain washed me into a storm drain, and I floated to the beach, where I now lie, slowly breaking into microplastics. Incorporate your research—mention the polymer type, its resistance to UV light, or the energy used in its production. Use themes like place, identity, behavior, or incongruity. For example, a bright red toy fragment on a gray rocky shore creates a stark contrast that speaks to human consumption.

Step 4: Creating a Visual Drawing

Words alone are not enough. Your drawing must merge spatial and non-spatial information. For instance, overlay a map of your collection site with a diagram showing the material's lifecycle—from extraction to disposal. Use at least two media types: perhaps a hand-drawn sketch of the beach with a digitally produced graph of decomposition rates. Keep it primarily black and white, with accent colors only after consulting your tutor. Annotations and legends will help viewers understand the story at a glance.

Example Drawing Concept

Imagine a drawing that shows a cross-section of a beach. On the surface, you see your plastic fragment. Below, layers of sand reveal older debris, and arrows indicate how tides move materials. Overlaid are icons representing the carbon footprint of producing that plastic. This combination of spatial layout and non-spatial data tells a powerful story.

Step 5: Assembling Your Deliverables

You need to submit three georeferenced photos, an A4 portrait document with material specifications and your essay (both Word and PDF), and an A3 portrait drawing (PDF, JPG, or PNG at 300 dpi). Use the course template for the document. Ensure your photos are clear and your drawing is legible.

Conclusion: Reflecting on Material Significance

By completing this assignment, you will gain a deeper appreciation for the materials that shape our world. In 2026, with microplastics found even in Arctic ice, understanding material flows is critical. Your material diary is not just an academic exercise—it's a step toward more mindful consumption and environmental stewardship.
