Semi-Detailed Lesson Plan in TLE-Electrical/Electronics

Concept: Resistor Color Code is a system of colors used to indicate the resistance value of resistors that uses colored stripes or bands printed on its body.

Value Concept: Color plays a vitally important role in the world in which we live. Color can be a form of communication. Color can sway thinking, change actions, and cause reactions.

I. Objectives: At the end of the lesson, the students expected to:1. Identify the colors of resistor color coding accordingly. 2. Calculate the value of resistors based on the color code.3. Adhere to the importance of using color.

III. Learning ActivitiesA. Preliminary Activities1. Prayer/Greetings/Introduction.2. Review of the previous topic. a. What is resistor?3. Motivation A.: Ask the students about traffic lights.

a. What is a traffic light?b. How does traffic lights work?c. What are in the traffic lights?

4. Motivation B:a. Provide resistor to every student for them to examine.b. Ask students on their observation of the given resistor.

B. Lesson Proper1. Introduce resistor color coding* Explain the concept of resistor color code.2. Introduce the colors involve in resistor color coding. See the visual aid. 3. Give the technique how to remember the colors.* Big Boys Race Our Young Girls But Violet Generally Wins Get Serious Now* Better Be Right Or Your Great Big Venture Goes West Get Serious Now

4. Discuss the designation of the 4 colors/bands resistors. 1st color/band: 1st digit2nd color/band: 2nd digit3rd color/band: Multiplier4th color/band: Tolerance

5. Give at least 3 examples on how to read the value of resistor based on its colors. 6. Ask at least 2 students to read the value of resistor given to them based on a given colors.7. Discuss the designation of the 4 colors/bands resistors.

1st color/band: 1st digit2nd color/band: 2nd digit

3rd color/band: 3rd digit4th color/band: Multiplier5th color/band: Tolerance

8. Then give at least 3 examples on how to name the colors of resistor from a given resistor value. 9. Ask at least 2 students to read the value of resistor given to them based on a given colors.10. Ask the students if they are able to follow the discussion.

C. Generalization: Ask questions that would elicit the ides/concepts taken. What is color coding of resistor? How to determine the nominal values of resistors?

D. Valuing: Using the value concept, let the students do the valuing based on the questions. Why are colors important? How do you relate colors in your daily life?

IV. Evaluation: Determine the value of the following resistors1. Brown, Black, Red, Gold= 1kΩ ±5%2. Yellow, Violet, Gold, Gold= 4.7Ω ±5%3. 100kΩ ±10%= Brown, Black, Yellow, Silver4. Green, Blue, Black, Black, Brown= 560Ω ±1%5. Orange, Orange, Black, Red, Brown= 33kΩ ±1%

V. Assignment1. What is the other method of determining the values of resistors?
