IMPACT OF TECHNOLOGY

Lesson Objectives

Objectives include understanding plastic, its recycling, and engaging in a class activity.

Plastic

• Definition: Plastic means "easily shaped" and is derived from non-renewable resources such as crude oil.

• Uses: It is cheap and versatile, allowing various applications.

• Types: Divided into Thermoplastic (can be reformed after heating; recyclable) and Thermosetting (cannot be reformed; mostly non-recyclable).

Recycling of Plastic

• Importance: Vital due to pollution caused by plastic.

• 3R's: Reduce, Reuse, Recycle.

  • Reduce: Limit plastic use by opting for alternatives like reusable bags.

  • Reuse: Encourage the use of reusable containers and bags.

  • Recycle: Involves processing used plastic into new products; must sort by type (using identification codes).

Class Activity

1. Steps for Recycling: Collecting, Sorting, Shredding, Cleaning, Melting, Manufacture of Grains.

2. Explanation of Steps: Each step from collection to manufacturing new products is outlined, emphasizing the transformation from waste to reuse.
