INTRODUCTORY MESSAGE Welcome to Science-Grade 5! The Learning Activity Sheet is self-directed instructional material aimed to guide the learners in accomplishing activities at their own pace and time using the contextualized resources in the community. This will also assist the learners in acquiring lifelong learning skills, knowledge, and attitudes for productivity and employment. For the learning facilitator: The Electronic Learning Activity Sheet in Science helps you facilitate the teaching-learning activities specified in Most Essential Learning Competency (MELC). This will be made available to the learners who are at-risk in Science subjects from Grade 3 to 6 identified learners who are part of the project E- LAS and Gamified App together with Project PRISE. For the learner: The Electronic Learning Activity Sheet in Science is developed to help you continue learning. This learning material provides you with meaningful and engaging activities for independent learning. Being an active learner, carefully read and understand the instructions then perform the activities and answer the assessments. This will be checked by your facilitator on the agreed schedule. Gamified app of activities was also provided to help you go through the lesson. Enjoy learning!

Science Activity Sheet No. 1 Title: PROPERTIES OF MATERIALS I. Learning Competency Use the properties of materials whether they are useful or harmful (S5MT Ia-b-1) II. Background Information for Learners The matter is found everywhere. All the things found in your environment that have mass and occupy space are examples of matter. Each material is made up of chemical substances. Matter can be solid, liquid, and gas and it can be found at home. Examples are the common household materials that we usually use for cleaning, cooking, eating, bathing, and repairing. They can be useful or harmful if not properly handled. Thus, reading the product label is very important to identify whether the material is harmful or not. Some materials may cause fire hazards, toxic or poisonous, may cause burns, and may react dangerously when combined with other materials. The usefulness of a certain material depends on its properties. There are materials that are durable and therefore can be reused many times. Though there are some that are not meant to be reused but creative and inventive people still find other ways to use them. III. Activity Proper Activity 1 Who I’m I? Below are pictures of some materials that we usually use at home. Identify them and choose the correct name for the following materials.

Activity 2: Where I made of? Direction: Give the material that the finished product was made of. Choose the letter of the correct answer. a. metal 1. b. plastic a. plastic 2. b. wood 3. a. glass b. metal 4. a. steel b. rubber 5. a. ceramic b. steel Activity 3: Crash, Bend, Stretch, and Scratch Direction: Study the following properties of materials. A. Hardness – the ability of a material to resist pressure B. Malleability - the ability of a material to be pounded into thin sheets C. Ductility – the ability of a material to be drawn into thin wires D. Porosity – the ability of a material to allow water and gases to pass through it E. Flexibility – the ability of a material to bend or roll without breaking easily F. Thermal Conductivity – the ability of a material to transfer heat from one area to another G. Brittleness – the ability of a material to be easily broken when dropped. H. Solubility – the ability of materials to be dissolved in another form of matter

I. Flammability – is the ability of a material to burn J. Elasticity – the ability of a material to return to its original size and shape without breaking K. Chemical Reactivity – the ability of material to react and produce new materials when combined with oxygen, acid, or water Direction: From the given pictures, identify the property of each material by choosing from the given list of properties above. Write the letter of your choice on the space provided. ______ 1. ______ 6. ______ 2. ______ 7. ______ 3. ______ 8. ______ 4. ______ 9. ______ 5. ______ 10.

IV. REFLECTION With this activities learners are expected to have knowledge and understanding about properties of matter. Activities engaging to learners that will help them continue with the lesson.
