1. LESSON 10: CHANGES IN SOLID MATERIALS ACTIVITY 2: WHAT HAPPENS TO THE SOLID MATERIALS WHEN BENT ?

2. GROUP GAME List down examples of solid materials that can be bent. List down as many solid materials as you can in 2 minutes.

3. GROUP ACTIVITY WHAT TO DO: Bend each of the given materials. Observe and describe what happens to each materials. Copy the table below in your science notebook. Record your observations.

4. MATERIALS What happened to the materials when bent? Plastic ruler Electric wire Paper clip Metal spoon Rubber slippers

5. MATERIALS What happened to the materials when bent? Plastic ruler When bent, plastic ruler change in size and shape but no new material is formed. Electric wire When bent, electric wire change in size and shape but no new material is formed. Paper clip When bent, paper clip change in size and shape but no new material is formed. Metal spoon When bent, metal spoon change in size and shape but no new material is formed. Rubber slippers When bent, rubber slippers change in size and shape but no new material is formed.

6. What happeed to the solid materials when they are bent? Was a new material is formed? What characteristics of solid were evident in this experiment?

7. Solid materials can be bent. When bent, these materials may change their size and shape. No new material is formed. Only the physical appearance of the materials is changed. REMEMBER THIS!

8. Bending of solid materials is applied in situations like: bending of steel bars/iron in industry, etc. REMEMBER THIS!

9. ASSIGNMENT: EACH GROUP WILL BRING THE FOLLOWING MATERIALS: 2 pcs. Modelling clay 2 pcs. Paper cups 1 pc. Banana 1 pc. Loaf bread 1 pc. Clean plastic sheet 1 pc. Small wood/ empty glass bottle/ large stone
