Petrochemicals and Plastics

~60 min · 15 stations

Petrochemicals and Plastics is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify raw materials derived from crude oil refinement processes; classify basic hydrocarbon chains based on molecular structure; define polymer structures through repeating monomer units.

Conductor

The Conductor

Welcome aboard the hydrocarbon express. We are tracking the transformation of crude oil into the plastic fabric of our modern world—mind the gap between atoms.
