Lesson Plan

• Describe the key properties of textile fibres such as tensile strength, elasticity, absorbency and thermal insulation.
• Compare natural, synthetic and blended fibres in terms of performance and typical applications.
• Analyse functional, aesthetic and environmental criteria to select appropriate textiles for a specific end‑use.
• Apply a selection checklist to evaluate and justify textile choices for a design brief.

• Projector or interactive whiteboard
• Slide deck with fibre property tables
• Printed handouts of the comparative fibre table
• Sample fabric swatches (cotton, wool, polyester, nylon)
• Worksheet containing the selection checklist
• Sticky notes or index cards for group activity
• Markers

“Imagine designing a sports jacket that must stay dry, lightweight and durable.” Use this scenario to activate prior knowledge about everyday textiles. Review the idea that designers match material properties to product requirements. State that today students will be able to identify key textile properties and justify material choices.

1. Do‑now (5’) – Students list common items made of textiles and discuss the properties those items need.
2. Mini‑lecture (10’) – Overview of natural, synthetic and blended fibres and their key properties, using slides and the fabric swatches.
3. Comparative analysis activity (12’) – Pairs examine the comparative fibre table and complete a worksheet matching properties to suitable end‑uses.
4. Selection checklist challenge (10’) – Groups receive a product brief (e.g., camping tent) and use the checklist to propose the optimal textile, presenting their rationale.
5. Whole‑class debrief (8’) – Teacher highlights correct reasoning, addresses misconceptions and reinforces the decision‑making process.
6. Exit ticket (5’) – Quick written response: “One property you would prioritize for a medical gown and why?”

Summarise how understanding fibre properties enables informed material selection for functional, aesthetic and environmental goals. Collect exit tickets to check understanding, and assign a homework task to research a sustainable textile (e.g., organic cotton or recycled polyester) and write a brief report on its suitability for a chosen product.
