QUARTER 1 WEEK 2 DAY 1 REVIEW Directions: What is the difference between physical and chemical property of materials? How many times do you use your cellphone in a day? How many hours do you spend on it? Why do you use it? RECOGNIZING USEFUL AND HARMFUL MATERIALS (S5MTIA-B-1)  How do the materials become useful or harmful?  USEFUL MATERIALS Materials are said to be useful when they serve their purpose. These may have properties such as durability, flexibility, elasticity, hardness, and resistance to water, heat, or acid. Most of the useful materials can be reused and recycled.  USEFUL MATERIALS For example, a container for solid or liquid, when it is already empty, can still be used for other purposes such as a flower vase, a coin bank, or a house decor. Whether a bottle is made of plastic or glass, it has a property that makes it reusable.  HARMFUL MATERIALS Other materials can be recycled by making new products from these materials. For example, candy wrappers can be turned into fancy curtains and plastic bottles into Christmas lanterns.  HARMFUL MATERIALS Some useful materials may also bring hazards. For example, a broken glass jar can cause cuts or injury. Toxic substances may also be present in the things you commonly use such as paints, cleaners, fumes, gels, or powders.  HARMFUL MATERIALS These materials may bring harm to your health, environment, and other organisms when not used properly. That’s why you should be careful when handling and using different materials. ACTIVIT Y 1 Directions: Copy the table. Observe how the materials in the pictures are being handled. Identify whether they are useful or harmful by putting a check mark (✓) on the appropriate column. ACTIVIT Y 1 Material Useful Harmful 1. 2. 3. 4. 5. ASSESSMENT ADDITIONAL RESOURCES Directions: Classify the following materials usually found at home and in school using the table below as a guide. ASSESSMENT ADDITIONAL cooking oilRESOURCES demonstration table laundry soap armchair bell Chalkboard bed frying pan Mosquito repellant flag Books class record ASSESSMENT Materials usually Materials usually ADDITIONAL RESOURCES found at Home found in School ASSESSMENT ADDITIONAL Which among the materials given can RESOURCES cause harm? Why? QUARTER 1 WEEK 2 DAY 2 REVIEW Directions: List 5 different materials used at home and in school. Write a sentence describing how the material can be useful or harmful. REVIEW Materials Sentence Useful in writing notes on the blackboard.
