least ten(10)
glass materials
found in the mall.

3. Who among you
are using plastics
at home?

4. What materials
found at home
are made of
plastic?

6. The uses and importance
of plastic materials in our
everyday lives is
incredible.
Most of us touch and use
different form of plastic
at any given time, on any
given day.

8. Activity 1
- Group pupils into four. Each group
will be given some plastic materials .
- Each group will have the same
materials as the other group, but
they will only work on their assigned
task.
- Observe each materials based on
its characteristics then write your
answers on a meta card. Post your
answers on the table posted on the
board.

degree of transparency to
light?

11. How do you describe the
magnetic property of plastics?
How about its thermal

property?

12. • What are plastics materials?
• Why do we need to know the
properties of plastics?
• Let us analyze our table. Are
plastics useful or harmful
materials? Why?

13. Plastics are useful
materials because it can be
use again and again without
breaking, cheap, attractive,
transparent, flexible, tough,
light in weight, good
insulator of heat or
electricity, non-rusting and
hygienic.

14. Plastics are useful in many
ways.
How does it become harmful
to people and the
environment?

15. How can you take your part
in saving our environment
from the harm posed by the
use of plastics?
