Changes in Solid Materials when Pressed.pptx
- 1. Review: What are the materials that can be bent? What happens to solid materials when bent?
- 2. DAY 3 ACTIVITY 3: “ What happens to the Solid Materials when Pressed?”
- 3. STUDY THE PICTURES GIVEN BELOW:
- 4. What do you understand about the pictures? Describe the action shown in the picture?
- 5. Pressed – to reshape or make compact by applying steady force; compress
- 6. Let’s Find Out! What do you think will happen when solid materials are pressed?
- 7. We are going to investigate this in our activity today. GROUP ACTIVITY
- 8. What do we need? •Paper cup •Banana •Pandesal •Dough •Wood •Large stone •Empty glass bottle •Manila paper •marker
- 9. What to do? 1. Using a piece of wood or empty glass bottle or large stone, press each of given materials. Observe what happens to each of the material. 2. Record your observations in your activity sheet.
- 11. Guide Questions: 1. What happened to the solid materials when they were pressed? 2. Was a new material formed when solid material was pressed? 3. What characteristics of solid were evident in this experiment?
- 12. Give situations where pressing of solid materials is applied.
- 14. •What happen to solid materials when pressed? •Was a new material formed when solid materials was pressed?
- 15. REMEMBER THESE: Solid materials can be pressed. When pressed, these materials may change their size and shape. Other solid materials may also change their texture when pressed. However, no new material is formed because only the physical appearance of the material is changed.
- 16. Assignment: Each group will bring the following materials for the next activity: 1 pc. block of wood 1 pc. Empty tin can (lata) 1 pc. Small sheet of galvanized iron 1 pc. hammer
