Name of Teacher : RAJESH KUMAR  Subject : Work Education Class :VII A,B,C           Month: April 2017

Pre-requisites/Recap ·         “Where does the energy we use come from?” ·          Is our supply of energy infinite or finite? Introduction ·         Sources of electricity are everywhere in the world. Worldwide, there is a range of energy resources available to generate electricity. These energy resources fall into two main categories, often called renewable and non-renewable energy resources. Each of these resources can be used as a source to generate electricity. ·         If the current flows always in the same direction, it is called 'direct current'. ·         If the current changes direction after equal intervals of time, it is called alternating current Teachers role ·         Explain sources of energy ·         Discuss major differences between non-renewable and renewable/alternative energy sources.  ·         Explain Renewable resources which includes solar, wind,hydro, geothermal and biomass. ·         Explain Non-renewable sources which include nuclear energy and fossil fuels. ·         Define electric current and explain advantages of Alternating Current over Direct Current

Students role ·         To identify non-renewable and renewable/alternative energy resources ·         Define solar energy, wind energy, hydro power, geothermal energy, biomass,nuclear energy and fossil fuels ·         Find out the contribution of non-renewable and renewable energy resources in fulfilling total energy requirement ·         Identify various sources of Alternating Current and Direct Current

Objectives ·         Students will understand how renewable energy provides a clean source of energy. ·         Students will be able to identify at least five sources of energy. ·         The student will be able to state that the depletion of fossil fuels is a serious global issue ·         Learn about unit symbol and graph of A.C and D.C

Resources used Chart, flash cards and PPT cell and batteries Supply mains as a source of A.C

Expected Outcomes ·         Students will be able to identify sources of energy. ·         Advantages and limitations of non-renewable and renewable energy resources ·         What are the environmental impacts of our energy sources? ·         Identify sources of A.C and D.C ·         Learn about advantages of A. C over D.C

Activities ·         Identify the number of renewable energy sources they come into contact with everyday (sun, wind, water) ·         Collect the sources of Direct Current

Assessment ·         Ask the students to give example of non-renewable and renewable energy resources ·         Ask the students to explain how renewable energy resources are eco-friendly ·         Ask the students that electric current they are using in school and at their home are A.C or D.C

Home Task ·         Draw the Pie chart showing the contribution of various energy resources used to satisfy energy requirement of the world ·         Draw the wave forms of Alternating current and Direct current ·         Draw the standard symbols used to represent A.C and D.C
