Identify household articles made up of natural and synthetic fibres in Synthetic Fibres and Plastics – Class 8 Science Experiment
Chapter Name: Synthetic Fibres and Plastics
Activity Name: Identify household articles made up of natural and synthetic fibres in Synthetic Fibres and Plastics
Activity Description:
In this activity, students will identify various household articles made up of either natural or synthetic fibres. They will observe their surroundings and categorize the identified items accordingly.
Required Items:
- Pen/Pencil
- Paper or Worksheet with “Table-1” for recording observations
Step by Step Procedure:
- Begin by explaining the difference between natural and synthetic fibres to the students. Natural fibres are derived from natural sources, such as plants and animals (e.g., cotton, wool), while synthetic fibres are man-made from chemical processes (e.g., polyester, nylon).
- Distribute the worksheet or provide a table where students can list the identified household articles.
- Ask the students to look around their immediate environment (classroom, home, etc.) and find examples of items made from either natural or synthetic fibres.
- Students should write down the name of each identified household article in the appropriate category in “Table-1” based on whether it is made of natural or synthetic fibres.
Experiment Observations:
Table-1:
| Natural Fibres | Synthetic Fibres |
|---|---|
| Wool | Polyester |
| Cotton | Nylon |
| Silk | Acrylic |
| Hemp | Rayon |
| Jute | Spandex |
| Polypropylene | |
| Viscose | |
| Polystyrene | |
| Polyethylene | |
| and so on… |
Note down your observations in table format:
Precautions:
- Ensure students handle household articles with care and avoid damaging any items during the observation process.
- Emphasize the importance of not taking items from others’ personal belongings without permission.
- Students should not handle any sharp or dangerous objects during the activity.
Lesson Learnt from Experiment:
Through this activity, students will become familiar with the various household articles that are made up of natural or synthetic fibres. They will understand the prevalence and versatility of synthetic fibres in everyday objects and recognize the significance of choosing appropriate materials for specific purposes.
