CURRICULUM CONTENT, STANDARDS, AND LESSON COMPETENCIES A. Content The learners learn that: Standards 1. Science processes help in observing and predicting how things move. 2. Pushes and pulls can change the position and shape of objects. 3. Gathering scientific information helps explain the behavior of objects and materials. 4. Magnets affect some objects and materials without touching them. 5. Energy is present whenever there is movement, sound, light, or heat. B. Performance By the end of the quarter, learners use simple equipment and processes to measure and record data related to Standards movement and describe and predict the way things around them move using more scientifically technical language and concepts, such as speed and force. They demonstrate an understanding that science processes are used to gain a deeper understanding about forces that cannot be seen directly, including the properties of magnets. C. Learning Learning Competency: The learners participate in guided activities to discover and predict how rigid and soft Competencies objects can be moved and/or changed in shape. and Objectives The learners will be able to: 1. Lesson Objective 1: identify rigid and soft objects based on physical characteristics. 2. Lesson Objective 2: classify objects as rigid and soft objects. 3. Lesson Objective 3: define force as a push or a pull exerted on an object. 4. Lesson Objective 4: describe forces using arrows in given situations. 5. Lesson Objective 5: identify forces in our daily tasks. 6. Lesson Objective 6: investigate how rigid and soft objects respond to applied forces. C. Content Describing Force A force is an action that changes or maintains the motion of a body or object. It is either a push or a pull. Forces can change an object's speed, its direction, and even its shape. D. Integration Safety – When pushing or pulling, one must be aware of the direction of force and movement of the object. Responsibility (Grade 3 GMRC & VE): Students understand their responsibilities at home and school. 1 II. LEARNING RESOURCES Booth, G., McDuell, B., & Sears, J. (1999). World of Science: Students’.

"Have you encountered situations where objects were pushed or pulled?" "Have you been involved in pushing or pulling something or someone?" Guide the students to review "In your experiences, was anyone hurt due to pushing or pulling?" the concepts of pushing and pulling by sharing their personal experiences related to these actions. Allow them to recall and discuss these experiences with a seatmate. Following the sharing, invite volunteers to discuss their experiences with the whole class. 2  Emphasize safety, especially when incidents involve someone getting hurt, prompting students to think about safety precautions when pushing or pulling objects or people. Students' responses may include pushing and pulling experiences when they play with friends in the playground or with their siblings or cousins at home. They may also mention students pushing when they are crowded during line formation or during dismissal. Remind them to maintain enough distance from other students during dismissal or assemblies to avoid getting hurt or accidentally pushing others. Be sensitive to students' responses, especially when they were hurt by their experiences. B. Establishing 2. Lesson Purpose Guide the learners in answering Lesson Purpose a.

Before learning further about forces, ask the students what they need to do Use Activity 3 to build students’ first if they need to conduct an experiment using certain materials.

Synthesize the activity by discussing their answers to the following process Encourage students to explore questions: and engage with the objects in 1. When can you say an object is rigid? a respectful manner. Remind 2. What are the physical properties of soft objects? them not to disturb or damage 3. Why is it important to distinguish between soft and rigid objects? any items in the classroom. Possible answers to Activity 3 guide questions. 1. An object is considered rigid if it is hard and cannot be easily bent, deformed, or compressed. 2. Soft objects can be easily bent, deformed, or compressed. 3. It is important to distinguish between soft and rigid objects because it determines how much 6  force is needed to change their shape, move, stop, or change their direction. When we know an object is rigid, we can exercise caution to avoid getting hurt or injured in pulling or pushing it.

Worked Example students' skills in describing After defining force, guide students to describe forces by drawing arrows in a forces in their daily activities. diagram to indicate where the force is directed and by writing a phrase including who applies the force to what object. The phrase is given in this Go through the first scenario pattern: something or someone pushes or pulls an object or person. together as a class.

Circulate the classroom to Answers: provide support, answer questions, and ensure students are correctly representing forces with arrows. Ensure students understand that arrows represent both the direction and strength of forces. But for this level, they are not required to measure the length of the arrow. You may tell them that a short arrow represents a A girl pressing the phone A boy is pushing the light small force, and a long arrow screen A boy is carrying a bag switch represents a big force. Possible answers to Activity 2 guide questions. 1. I represented a pushing or pulling force in the diagram using arrow. 2. Yes, if my friend and I are pulling both ends of a rope in a tug-o-war with equal forces. The arrows representing our forces are two equal arrows in opposite The bigger hand is pulling The girl is sweeping directions. A boy is pulling a chair the rubber band the floor 8  After completing the activity, lead a class discussion to reinforce the concepts learned. Ask students to share their drawings and discuss their answers to the following questions: 1. How would you represent a pushing force in a diagram? What about a pulling force? 2. Can you identify situations in which forces are balanced or equal? How would you draw the arrows for balanced or equal forces? 3. Lesson Activity a. Activity 5: Forces in My Everyday Life (20-25 minutes) Use Activity 5 to deepen their Deepen students’ understanding of forces by asking them to identify understanding of the forces in different forces present in their everyday lives. Ask them to answer Activity their daily activities. Go 3: Forces in My Everyday Life. Ask each student to illustrate four situations through the first scenario wherein they do actions (that apply a push or a pull) to accomplish daily together as a class. Give them tasks at home or at school. They must draw arrows to show where the force enough time to think about is directed and label or caption each situation using the pattern: I am their situations in their daily pushing/pulling an object + direction. lives.

This activity Summarize the lesson's key points, emphasizing how understanding forces reminds them of home and in everyday life is essential. Encourage students to remain observant of school responsibilities, like forces in action around them and consider how these forces impact their cleaning, washing, sweeping daily activities. the floor, and other chores. Key points of the lesson: 1. Forces are Everywhere: Forces are all around us, influencing how objects move and interact. 2. Impact on Daily Activities: Forces influence how we interact with objects around us, like pushing a shopping cart, pulling a rolling backpack, or playing with friends. 3. Applying Scientific Processes: By observing how things move, we can better understand the forces at play in our environment. 9 D. Making DAY 4 Conduct a short discussion Generalizations 1.
