You need to pick a real chemical process from the world around you—either an environmental problem (like acid rain or ocean acidification) or a new technology (like polymers or pharmaceuticals)—and explain how the chemistry actually works. Your explanation needs to use proper chemistry vocabulary, symbols, equations, and show you understand what's really happening at the chemical level.
What to do, grades and common mistakes
What you actually do
- ·Identify and describe a specific chemical process from either an environmental issue or a technology that solves a real-world problem
- ·Explain the chemistry happening in that process using correct vocabulary, chemical symbols, and equations
- ·Show how that chemical process connects to its consequences—what actually happens to the environment or people as a result
- ·Link multiple chemical ideas together to show deeper understanding of how and why the process works
- ·Evaluate or analyse the broader impact and issues that come from the chemical process, comparing different aspects or effects
AAchieved
You explain a chemical process clearly with correct terminology and equations, describing what happens and why.
