13. Group Activity
Do Activity 3
“What Happens to Solid
Materials when Pressed?”

14. Materials:
1 pc of banana
Pandesal
Clean plastic sheet
Small wood
Empty glass/bottle
Large stone
¼ kilo dough

15. Activity 2: What Happens to Solid Materials when Bent?
Material Observation
Modeling clay
Paper cup
Banana
Pandesal
dough

16. Guide Questions:
1. What happened to the solid
materials when they are pressed?
2. Was a new material formed
when solid material was
pressed?
3. What characteristics of solid
were evident in this experiment?

17. Elaboration:
Solid materials can be
presses. When presses, these
materials may change their
size and shape. Other solid
materials may also change
their texture when pressed.

18. However, no new material is
formed because only the
physical appearance of the
material is changed.

19. Draw if the activity showed
materials being pressed and if not.
