This agenda slide outlines a presentation on the scientific evolution of clothing materials, starting with an introduction, past use of natural fibers from plants and animals, and today's petroleum-based synthetics. It concludes with a comparison of durability, cost, and environmental impacts, followed by key insights and future implications.
Presentation Agenda
- Introduction to Clothing Evolution
Overview of how clothing materials have evolved scientifically.
- Clothes in the Past: Natural Materials
Natural fibers from plants and animals, biodegradable with natural dyes.
- Clothes Today: Synthetics
Synthetic fibers from petroleum via chemical reactions in factories.
- Comparison & Impact
Compare natural vs synthetics on durability, cost, and environment.
- Conclusion

Detailed notes:
Slide 1: Clothes in the Past - Science Focus: Natural Materials
- People used clothes made from natural fibers like cotton, wool, silk, and linen.
- These materials came from plants and animals and were biodegradable.
- No chemical processing; natural dyes from plants and minerals.
Slide 2: Clothes Today - Science Focus: Synthetic Materials & Chemical Industry
- Many clothes are made from synthetic fibers such as polyester, nylon, and acrylic.
- Made in factories from petroleum using chemical reactions.
- Strong, waterproof, and cheap but not environmentally friendly.
