Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson. Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you. Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these. In addition to the material in the main text, Notes to the Teacher are also provided to our facilitators and parents for strategies and reminders on how they can best help you on your home-based learning. Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task. If you have any questions in using this SLM or any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator. Thank you. ii  What I Need to Know Everything around us is matter – the soil, water, and air. Matter has different properties that make it distinct from one another. Some types have properties that make them good materials for producing useful products. Other types have properties that make them harmful. There are different materials found at home. These are important because they are used in our daily activities such as cooking, cleaning our houses, treating ailments, maintaining personal hygiene, and many more. It is important to know their different properties so that we can identify whether a certain material is harmful or useful. This module focuses on the different properties of matter that can be classified as useful or harmful. This also gives the importance of recognizing the physical and chemical properties of matter in determining the usability of a certain material. Moreover, it emphasizes the importance of product labels in identifying useful and harmful materials. The module is divided into two lessons, namely: Lesson 1: Recognizing Useful and Harmful Materials Lesson 2: Importance of Labels in Identifying Useful and Harmful Materials At the end of the module, you will be able to: identify the different properties of matter that can help you determine whether it is harmful or useful; enumerate useful and harmful materials at home and in school; and explain the importance of labels in identifying useful and harmful materials Note: Use a separate sheet for your answers in all the activities in this module 1 CO_Q1_Science5_Module1  What I Know A. Directions: Determine which of the activities below is desirable or harmful. Write D if desirable or H if harmful. 1. Placing the biodegradable wastes in the compost pit 2. Smelling the fumes exhausted by cars 3. Throwing banana peelings anywhere 4. Covering the textbook with acetate 5. Burning plastic bottles B. Directions: Put a check (✓) mark if the statement is correct, an (X) mark if not. 1. Halal certified food can be consumed by Muslims. 2. Keep pesticides in areas away from children’s reach. 3. All household materials are useful. 4. Muriatic acid can be labeled as corrosive and poisonous. 5. Recyclable materials such as empty water bottles are harmful. 2 CO_Q1_Science5_Module1 Lesson Recognizing Useful and 1 Harmful Materials What’s In Directions: Classify the following materials usually found at home and in school using the table below as a guide. cooking oil demonstration table laundry soap arm chair bell chalkboard bed frying pan mosquito repellant flag books class record Materials usually found at Home Materials usually found in School 3 CO_Q1_Science5_Module1  What's New 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. OBJECT USEFUL HARMFUL 1. broken glass ("Shattered Glass Free Image | Peakpx" 2016) 2. an empty bottle being refilled (Balsanos.n.d) 3. candy wrapper-made bag (Prevost, Shelly.2011) 4.vegetable peelings made into compost ("Royalty-Free Photo: Bunch Of Fruit Peels|Pickpik" 2021) 5.used boxes as book organizers (Greyling, Lynn.n.d) 4 CO_Q1_Science5_Module1  What is It How do the materials become useful or harmful? 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. 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. 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. 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. 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. What’s More Activity 1: Where do I belong? Directions: Classify the different materials found in the word pool below as useful or harmful.

Directions: Write True if the statement is correct, and write False if it is incorrect. 1. Consumers must read product labels when buying grocery items. 2. Place fertilizers in containers and label them as poisonous. 3. Throw away anywhere the plastic bottles after using them. 4. Labels are not important in classifying materials as to useful or harmful. 5. Food allergen warnings are helpful especially for those who have allergies. What is It Various household products are found in our homes. These are composed of different materials with different properties. It is therefore important for consumers to read product labels. Through product labels, consumers become aware of whether the product is harmful or not. Expiration dates and hazardous signs are some of the most important elements in a product label. Some products are flammable, such as paints and therefore must be stored away from open flames. Others are corrosive, like muriatic acid, so it is advisable to keep them away from children’s reach. Pesticides, fertilizers, and muriatic acid are poisonous if not handled properly. Reading product labels can help you identify whether the product is useful or harmful. These simple symbols in labels give ideas on how to use and store the product properly, and to help prevent accidents from happening and therefore save lives. The following are common signs in product labels which can help consumers decide whether the product is useful or harmful: 8 CO_Q1_Science5_Module1  Symbol Meaning Example Useful Product Labels Halal - product is certified as safe for consumption (for Muslims) ("Halal Sign And Symbol Logo (Floro, Florentino.2017) Vector Image On Vectorstock" 2021) Food Allergen Warning - warns consumers of ingredients in the ("File:US Allergen Information product that may Example.Jpg - Wikimedia Commons" ("File:Ale Rgias.Png - Wikimedia cause allergy 2010) Commons" 2019) Recyclable - products can be recycled (“Recyclable-Sign-Green-Background- ("File:Recycling Codes On Products.Jpg Shadow-Free Image From - Wikimedia Commons" 2014) Needpix.Com”.2021) Flammable - can easily catch fire ("Inflammable,Signs,Danger,Warning, Flammable - Free Image From ("Category:Kerosene - Wikimedia Needpix.Com" 2021) Commons" 2007) Poisonous - harmful to the body; may cause death ("File:WHMIS Class D-1.Svg - Wikimedia Commons" 2006) ("Free Images-Poisonous-598652-Free Stock Potos-Pxhere”.2021) Corrosive - can cause severe burns ("Safety,Signs,Corrosion,Alkali,Acids - ("File:Battery Fluid, Plastic Bottle.Jpg - Free Image From Needpix.Com" 2021) Wikimedia Commons" 2017) 9 CO_Q1_Science5_Module1  What’s More Directions: Copy and complete the table below.
