Lesson Plan

• Describe the key working properties of nanomaterials, metal foams, super alloys and bioplastics.
• Explain common applications for each material class in contemporary technology.
• Evaluate the environmental impacts and sustainability considerations associated with these materials.
• Compare the advantages and limitations of each material for specific design contexts.
• Apply selection criteria to choose an appropriate material for a given design brief.

• Projector or interactive whiteboard
• Teacher laptop with slide deck
• Student handouts summarising each material’s properties, uses and impacts
• Worksheets for group analysis
• Sample images/diagrams of nanocoatings, metal foams, super‑alloy components and bioplastics
• Markers and flip chart paper
• Exit‑ticket cards

Begin with the question, “What if your phone screen never got greasy?” to spark interest in advanced surface treatments. Recall students’ prior knowledge of basic material properties such as strength and density. Explain that today they will explore cutting‑edge materials, identify their uses, and assess their sustainability. Success will be measured by their ability to match properties to applications and discuss environmental trade‑offs.

1. Do‑now (5'): Quick quiz on familiar material properties (strength, conductivity, biodegradability).
2. Mini‑lecture (15'): Slide‑based overview of nanomaterials, metal foams, super alloys and bioplastics – focusing on properties, common uses and environmental impacts.
3. Guided group analysis (20'): In groups of 3‑4, students examine a handout for one material, fill a worksheet identifying key properties, applications and sustainability issues.
4. Whole‑class share (10'): Each group presents a summary; teacher highlights similarities and differences across material classes.
5. Case‑study activity (15'): Provide a brief design brief (e.g., lightweight, heat‑resistant component). Groups select the most suitable material and justify their choice using the criteria discussed.
6. Exit ticket (5'): Students write one advantage and one environmental concern for the material they chose.

Recap the main properties, applications and sustainability considerations of each material class. Collect exit tickets to gauge understanding and address any misconceptions. For homework, ask students to research a recent innovation involving one of these materials and prepare a short one‑page report on its potential environmental benefits.
