Content Standard:

The learners demonstrate an understanding about the importance of electric components in electrical devices. Topic: RESISTORS COLOR CODE Learning objectives: Code: STEM_GP12EM-IIIf-47  a.  Determine a resistors value by examining its color bands;  b.  Compute the tolerance of resistors; c.  State the importance of resistors in electrical devices. Resources Needed: Visual aids, Laptop, Projector, Chalk, Chalkboard, ppt  presentation, Resistors Values Integration: Honesty Procedure: Methodology Elements of the Plan

 

A. Preparation a.  Prayer  b.  Checking of Attendance c.  Setting the Mood

c.  Recapitulation of the  past lesson

Ask them to stand and pause for a while to pray the morning  prayer. Ask the students who are absent for this day. Do classroom routines. 1.  Pick up some pieces of paper around their chair. 2.  Ask them to sit properly. 3.  Ask them to be silent. Ask the students about their idea regarding the past lesson. Let them ask questions if they have something to clarify. If all the clarification is done, proceed to the next activity.

B. Development of the Lesson a.  Motivational Activity

4-Pics 1-Word Let the students answer the 4-pics 1-word activity to be projected using the projector or using the visual aid as the case may be. Divide the class into three groups and let them analyze the  pictures and ask them to write their answer on their whiteboard. Check their answers.

 b.  Analysis

Connect the motivational activity to the lesson. Ask the question below:  Have you seen resistors? What have they notice to the resistors? Introduce the topic about Resistors Color Code. Ask the student, what is resistance? The student must arrive that Resistance (R) is the amount of

opposition to the flow of electrical current.  Resistance is measured in units called ohms, named after German scientist and mathematician Georg Simon Ohm (17871845), and it is symbolized by the Greek capital letter omega (Ω).   (Ω). Explain what are the three most important characteristics of a resistor are? Discuss how the Resistance of the Resistors Measured? Explain how do we know which color corresponds to which number? Discuss the Resistor Color Code Explain how to calculate tolerance range of resistor Ask the essential question, why resistors are important in electronic devices? Give varied examples on how to compute the resistance value and tolerance of resistors. The teacher will group the student into three. The teacher will provide the colored resistors. Each group will get five colored resistor. They will calculate the resistance and get the maximum and minimum tolerance of the colored resistors. They will write their answer with solution to one whole sheet of paper. 1-minute asking activity-Ask the student to write one question regarding a concept that is unclear to them. Let them write it on a  piece of paper. Collect all the questions and clarify all the misconceptions.
