Science 4 week 2 Day 1 4 Quarter 3 Force Exerted by a Magnet Force at a Distance and Properties of a Science 4 week 2 Day 1 4 Quarter 3 Force Exerted by a Magnet (Force at a Distance) and Properties of a Magnet The learners learn that: 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. By the end of the quarter, learners use simple equipment and processes to measure and record data related to 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. Learning Competency 1: The learners identify examples of how objects can affect other objects even when they are not in contact with each other, such as magnets attracting other objects. Learning Competency 2: The learners carry out guided investigations to identify the properties of magnets, including how they affect other magnets and objects made of different materials. The learners will be able to: 1. Lesson Objective 1: identify common magnetic materials (e.g., iron, steel, nickel) and non-magnetic materials.2. Lesson Objective 2: recognize that magnets’ opposite poles attract while like poles repel. 3. Lesson Objective 3: identify and describe key properties of magnets, such as polarity, strength, and the ability to attract certain objects. Force Exerted by a Magnet (Force at a Distance) and Properties of a Magnet Force can be exerted without touching an object, like the force exerted by a magnet. Magnets attract materials made of iron, nickel, and cobalt. Materials that do not contain these metals are non- magnetic, like wood, plastic, cloth, etc. Earth is a big magnet. The strength of magnets varies. Magnets have two poles, the north (N) and the south poles (S). Similar poles repel while opposite poles attract. Many objects used in our daily lives contain magnets, like speakers, cell phones, magnetic locks of bags and wallets, and refrigerator magnets, among others. Technology - Applications of magnets in various technologies, such as magnetic levitation trains, MRI machines, and electric motors. Many objects used in our daily lives contain magnets, like speakers, cell phones, magnetic locks of bags and wallets, and refrigerator magnets, among others.
