1. Lesson 1: Assembly of Extension Cord (Discussion) Demonstrate/show how to assemble an extension cord, then lead your discussion to electrical tools and materials used in assembling basic electrical gadgets. 2. Lesson 1A: Electrical Tools and Materials (DemoTeaching) Present actual example or pictures of different tools, supplies and materials. Discuss the safety measures and precautionary measures with your learners. Post a few reminders like “Prevention is better than Cure”. Activity 1: Venn Diagram – Similarities and Differences Ask them to give their observation/s by comparing a Do-ItYourself DIY extension cord with a ready-made extension cord available in the market. Discuss the directions and reminders for proper use of an extension cord. You can ask them to perform it through role playing. 1. Extension Cord Ask your learners to demonstrate the actual making of an extension cord. 2. Table – Power Consumption Guide them in studying the power consumption table and interpreting the graph. The aim of this activity is for your learners to know how to use electrical appliances wisely. 3. Enumeration Let the learners list down some possible combinations of appliances that can be plugged-in to a #18 flat cord extension. 4.

Group Activity Group the learners into teams and assign a leader. Ensure that the learners understand the safety reminders 4
D. Transfer
to be followed in learning the soldering techniques. 13. Tester Discussion Discuss the lesson about multi-testers, continuity testers and test lights. In the discussion use the actual gadgets as much as possible. Guide them in doing the suggested activities about the continuity tester and test light. Practical Test Let the learners make the different measuring scales in their lecture notebook. Let them use the multi-tester one by one. The suggested activity in the module is about the identification of parts and the actual use of a multi-tester. In making a continuity tester and a test light, explain well the procedures in its assembly and discuss safety measures to be observed while assembling and using the gadgets. 1. Electrical Gadgets Discussion Discuss the basic electrical gadgets. In discussing the basic electrical gadgets use software like power point or use websites like YouTube as a reference. If this technology is not available. Try to use some visual aids. 2. Project Making (Group Dynamics) Guide your students to perform the following suggested activities. Heaters Extension cords Lamp shade assembly Water heater Continuity tester Test light Note: You can group the learners into groups of five. Each group will be assigned one item to accomplish. Group 1 – Heater Group 2 - Extension Group 3 - Lamp Shade Group 4 – Continuity Tester Group 5 – Test Light
VI.SUMMARY Electricity is a form of energy that can help us to make our tasks easier and help make our economy a successful one. However, electricity is dangerous and it can be harmful to everyone. Having skills in measuring devices, such as voltmeter, ammeter, wattmeter, ohmmeter, frequency meter, and multi-tester is very essential in any electrical work. These instruments are specifically useful in determining the actual amount of current and voltage electrical circuits have. They are also important in trouble-shooting and servicing all types of electrical products and circuit systems. Every measuring instrument should be used with care and skill and should be properly maintained. You must therefore learn the basic concepts in the effective utilization of measuring instruments, observe precautionary measures to avoid 5
damaging the meters, and perform repair work on them when needed. With the help of this module you are now really equipped and have gained more bits of information in order to use electricity in your everyday life. Also, you can practically have an income if you use your abilities and skills whole heartedly for your community. Note: Go over with the learning goals and target of your students which they have written at the start to check if they have attained their goal and targets. If not, check what needs to be improved.
