Unit 1
IN THIS AoS3
Gives students the opportunity to investigate how chemistry can contribute to a more sustainable and environmentally responsible future.
Students select a material or chemical process—such as polymers, metals, or natural products—and explore how it is produced, used and recycled. They learn to evaluate real scientific information, consider sustainability factors such as green chemistry and the circular economy, and communicate their understanding clearly through a structured research task.
This investigation helps students develop essential research, analysis and communication skills that build confidence for later VCE studies and future STEM pathways.
-
You will be able to:
Choose a chemistry-related sustainability issue.
Explain the underlying chemical principles.
Analyse and interpret scientific data or research.
Evaluate environmental, social, and economic impacts.
Apply concepts such as green chemistry and the circular economy.
Communicate findings in a clear and scientific manner.
-
1️⃣ What Is a Sustainable Chemistry Investigation?
It is a research project where you explore:
How a material is made, used, and disposed.
How chemical processes affect people and the environment.
How chemistry can improve sustainability.
2️⃣ Choosing a Research Topic
Your investigation can focus on:
A material (e.g., aluminium, PLA bioplastic, detergents).
A chemical process (e.g., electrolysis, polymerisation).
An environmental issue (e.g., microplastics, corrosion, recycling technologies).
An Indigenous chemistry practice (e.g., fermentation, natural dye extraction).
3️⃣ Green Chemistry Principles (Simple Overview)
Green chemistry aims to design materials and processes that:
Use less energy.
Produce less waste.
Use safer chemicals.
Improve efficiency and resource recovery.
4️⃣ Circular Economy Concepts
A circular economy focuses on:
Reuse.
Recycling.
Repair.
Resource recovery.
5️⃣ Communicating Your Findings
Your final work may include:
A written report.
A poster.
An oral presentation.
-
Conceptual Questions
What is the goal of green chemistry?
Explain how recycling supports the circular economy.
Why is life-cycle analysis useful when comparing materials?
Predict the shape and polarity of NH₃.
Provide one example of how chemistry helps reduce environmental impact.
Calculation Questions
Choose a polymer. Describe one sustainability advantage and one limitation.
Explain why corrosion prevention can improve sustainability.
Compare the sustainability of aluminium vs plastic packaging.
-
Focusing on environmental issues without explaining the chemistry.
Describing sustainability too generally (needs chemistry detail).
Forgetting to evaluate advantages and limitations.
Not linking research findings to chemical principles.
-
Always connect your topic to clear chemistry concepts.
Use graphs, tables and diagrams to communicate results.
Focus on how chemistry improves sustainability.
Keep your explanations concise and evidence-based.
