Reviewing previous lesson or presenting the new lesson These steps should be done across the week. Spread out the activities appropriately so that students will learn well. Always be guided by demonstration of learning by the students which you can infer from formative assessment activities. Sustain learning systematically by providing students with multiple ways to learn new things, practice their leaning, question their learning processes, and draw conclusions about what they learned in connection to their experiences and previous knowledge. Indicate the time allotment for each step. INDICATOR 2.Used a range of teaching strategies that enhance learner achievement in literacy and numeracy skills. INDICATOR 9. Used strategies for providing timely, accurate and constructive feedback to improve learner performance The teacher will review the previous lesson on WORK and POWER by asking students questions and do the following: 1.

Grade 9 MELC-Explain how thermal energy can be used to do work (S9FEIVf-5); Grade 10 MELC-differentiate between electrical power and energy (S10FE-IIe-21) After which, the teacher will engage and motivate the class by asking the question: What comes into your mind whenever you hear the word ENERGY? Then teacher will present the Unlocking of Difficulties to provide students with the important Terms of lesson. 1. Energy – the capacity to do work 2. Potential Energy – energy of an object at rest. It is also called stored energy. It has potential to do work once release. 3. Kinetic Energy – energy possesses by a moving object. It comes from the Greek word “kinetikos” which means moving. Kinetic energy quantifies the amount of work the object can do because of its motion. 4. Work – is a way of transferring energy. Once work is done on the body it gains energy. But if a body does work it losses energy. 5. Joule – unit of work and energy. It is also equivalent to 1 Nm and 1 kg m2 /s2 C. Presenting examples/instances of the new lesson Then, the teacher will provide examples/instances of the new the lesson by showing learners different examples and sources of energy.
