Introduction
Where do we find natural fibers and uses of natural fibers
Pre-Requisites:
Basic knowledge on fibers
Activity:
Observe your clothes and differentiate plant fiber clothes and animal fiber clothes
Real Life Question:
What is natural fiber used in making clothes in summer comfortable?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| fiber | Fibers are materials in the form of continuous filaments |
| Natural fiber | Fibers which are derived from nature are natural fibers |
| monomer | Building block of a polymer. Individual molecule which combines to form polymer |
| polymer | Polymer is a very large molecule of connected monomers. |
| Nucleotide | Structural units of RNA and DNA. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Fiber chart | Have a chart which classifies and differentiates fibers into groups like natural and synthetic fibers further differentiate natural fibers into plant and animal fibers. |
Real life uses :
Natural fibers are used in clothing and are also a part of diet.
Practical examples around us
| Examples | Explainations |
|---|---|
| Slowly people are shifting from plastic bags to jute bags. Why? | Jute bags are bio degradable which is not the case with plastic bags which are not bio degradable. Jute bags are eco-friendly. |
What you learn in Theory:
Natural fibers, uses of natural fibers, monomers and polymers.
What you learn in Practice:
How we can use fibers from nature to make our lives comfortable by clothing.
