DAILY LESSON PLAN - 2023 Grade: 7/8 Strand Sub Strand Sources of Energy and Transformation of Energy Week: 1 Physics Outcomes PH1.10: Identify energy transfers occurring around us and justifies the law of conservation of energy Indicators a) Explores the energy transfer taking place in various situations, appliances and gadgets (e.g., flash light, television, electric stove, bulb). b) Represents the process of energy transfer with the help of energy transfer diagrams. c) States and explains the law of the conservation of energy with the help of examples Key Competencies Sub strand Thinking Critically & creatively Indicators Activity Critically & creatively CC.KS3.02 Assess information reasonableness, find relevance, uncover assumptions, and draw inference, articulate reasoned judgments Group activity Energy transfer diagram / THINK PAIR SHARE discussion Lesson Title: ENERGY TRANSFER Learning Intention: Success Criteria: To identify how energy is transfer occurs in different situation I was able to Duration: 35 min - Describe the two law of energy conservation. List down at least five different forms of energy. Source of energy in three different components used to light up a room. Identify the source of energy, energy input & energy output in each of the component Success criteria display / Flash light, phone, candle , bulb in class room Materials required (per class/group) Energy transfer diagram and Advanced Planning Learning Activities Engage: Activity 1# Introduction to student. Right your name and one distinct physical feature as a clue in the sticky note given. In groups keep the names in wrong order. Ask the teacher to organize them using the clues. Before starting the lesson. Display the three objects you have brought. Ask the students what is common in these three things. They will guess that all of them are used as a source of light. Ask them what light is and let them describe light as a form of energy. Ask the students to write as many different types of energy they can think of by observing the class room. Explore: Display the flash light, the candle, the lighter and the bulb. Investigative technique Process skills Ask them to observe the objects and discuss in groups, where is the light generated and what is the source of the light energy. Each object will have a different source of energy, but the type of energy used will be same. For example, Sun is the main source of energy. but the energy used is chemical energy. Food is a source of energy but the energy used is chemical energy. Explain: Explain the law of energy conservation, law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. Different sources of energy: Fuel, sun, food, battery, candle wax, water, wind , nuclear , oil , biomass Types of energy: Light energy, heat energy, Electrical energy, chemical energy, sound energy , elastic energy Illustrate an example of an energy transfer diagram. Elaborate: Individual task: Ask each student to illustrate a neat and accurate Energy transfer diagram which shows all the energy transferred in the correct order. They must label the source of energy and receiver as well. Think -Pair Share: If additional time is available after completing the task, pair up students Give each pair a situation where energy transfer occurs In pairs ask them to think about the situation, face each other and share ideas, one person talk at a time. Share the final answer by explaining the energy transfer of the situation to the class /teacher. Evaluate:. Formative Assessment Summative Assessment Assess the diagram drawn by students. Assess during group discussion.

A Vehicle Being Accelerated by a constant Force Solar powered Toy car Camp fire burning to provide light A hungry goat eating grass Bell ringing in class Solar powered cap with a fan AC cooling the room Radiator inside the car Boiling Water in a Kettle ROLLER COASTER At the start electrical energy is used to pull the cars to the highest point in the ride. The electrical energy is converted to gravitational potential energy (GPE). As the cars run down the slope this GPE is converted to kinetic energy (KE) and some heat lost due to friction. As the car run up the next slope the kinetic energy is converted back to GPE. This exchange from GPE to KE continues throughout the ride until too much energy is lost due to friction and the ride will come to an end.
