Science Group for Elsian Day Presentation: Clothes Then and Now (High-Energy Science Theme) Style: Vibrant background with glowing blue and purple gradient, featuring dynamic laboratory visuals like molecules, beakers, and energy lines. Professional modern typography and visually engaging layout. 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.
Explores clothing's scientific shift from past natural fibers (cotton, wool, biodegradable) to today's synthetics (polyester, nylon from petroleum), highlighting chemical processes, benefits, and envi
This title slide is named "Clothes Then and Now." Its subtitle reads "High-Energy Science: From Natural Fibers to Synthetics."
High-Energy Science: From Natural Fibers to Synthetics

This agenda covers clothing evolution from past natural fibers like cotton and wool—biodegradable and chemical-free—to modern synthetics like polyester, nylon, and acrylic, which are durable but polluting. It concludes with a comparison of benefits, drawbacks, environmental impacts, and future sustainable innovations.
Natural fibers like cotton and wool from plants, animals; biodegradable.
Cotton, wool, silk, linen; natural dyes, no chemicals.
Synthetic fibers like polyester from petroleum chemicals.
Polyester, nylon, acrylic: strong, cheap, waterproof but polluting.
Natural vs synthetic: benefits, drawbacks, environmental impact.
Summary, sustainable innovations ahead. Source: Science Group for Elsian Day Presentation: Clothes Then and Now (High-Energy Science Theme)
This slide serves as the section header titled "Clothes in the Past," labeled as section 01. Its subtitle highlights the science focus on "Natural Materials from Plants and Animals."

The "Then vs. Now" slide contrasts past clothing made from natural, biodegradable fibers like cotton, wool, silk, and linen, dyed with plant-based eco-dyes and no chemical processing. Modern clothing uses synthetic fibers like polyester, nylon, and acrylic from petrochemicals, which are durable, waterproof, and affordable but less sustainable due to high-energy production.
| Then: Natural Materials | Now: Synthetic Materials |
|---|---|
| Clothes from plant/animal fibers like cotton, wool, silk, linen. Biodegradable, plant-based, colored with eco-dyes from plants/minerals. No chemical processing—purely natural science. | Fibers like polyester, nylon, acrylic from petro-chemicals via factory reactions. Durable, waterproof, affordable but less sustainable—high-energy chemical industry impact. |

Around 70% of modern clothes are synthetic fibers derived from petroleum, which take over 200 years to decompose in landfills. In contrast, 100% of natural fibers are renewable, sourced from plants and animals.
