(ELECTRICITY)

MAY 18, 2015

MONDAY

9:00 AM- 9:30 AM

I. OBJECTIVES: At the end of the lesson, 85% of the students should be able to:A) define electric circuit.B) recognize the two types of electric circuit.C) connect/assemble the actual electric circuit.D) value the importance of each essential parts of electric circuit.

II. LEARNING TASKA. SUBJECT MATTER: Electric CircuitB. CONCEPT/IDEAS: Electric Circuit, path of an electric current. The term is usually taken

to mean a continuous path composed of conductors and conducting devices.C. REFERENCES: Industrial Arts for Secondary Education ( Exploratory)

Basic Electricity Second Edition (Handbook) Encarta Encyclopedia (2007 Edition) Encarta Dictionary (2007 Edition)

D. MATERIALS: Cartolina, Pentelpen, Chalk, PDX wire, switch, junction box, electrical tape, side cutter, long nose pliers, combination pliers, lamp holder, illustration boad.VALUE FOCUS: Awareness of students about Electric Circuit.

III. PROCEDURE:A. PRE-ACTIVITY

I. PRAYERII. REVIEW

QUESTIONS: What are the sources of electricity? A source of electricity which is formed from natural matter such oil, and

natural gas? A source of electricity that comes from the force of a moving air?

TEACHER’S ACTIVITY

“Now, we know already where did the electricity came from. But the question is, how it is distributed to every consumer?

B. ACTIVITY PROPERI. PRESENTATION OF LESSON:

TEACHER’S ACTIVITY

“TODAY, we’re going to talk about electric circuit. What is electric circuit?

II. UNLOCKING OF DIFFICULTIES: TEACHER’S ACTIVITY

“The Encarta Dictionary defines Circuit as a Circular path or a route.”

III. DISCUSSION ELECTRIC CIRCUIT

O A complete path where electricity flows from the source to the load. THE FOUR ESSENTIAL PARTS OF ELECTRIC CIRCUIT

A. Source – provide the electrical pressure in the circuit.Example:

Battery & AC outletB. Conducting path – brings the electricity towards load.

Example: Metal conductor

C. Controlling device/ switch – controls the flow of electricity, depending upon the discretion of the operator.

D. Load – converts electricity to other form of energy.Example: Electric motor, light bulb. Television, refrigerator, etc.

I. TYPES OF ELECTRIC CIRCUIT

There are two types of electric circuit , called series and parallel.

The components in a circuit are joined by wires.

if there are no branches then it's a series circuit if there are branches it's a parallel circuit

A. Series circuits

In a television series, you get several episodes, one after the other. A series circuit is similar. You get several components one after the other.

If you follow the circuit diagram from one side of the cell to the other, you should pass through all the different components, one after the other, without any branches.

If you put more lamps into a series circuit, the lamps will be dimmer than before.

In a series circuit, if a lamp breaks or a component is disconnected, the circuit is broken and all the components stop working.

Series circuits are useful if you want a warning that one of the components in the circuit has failed. They also use less wiring than parallel circuits.

B. Parallel circuits

In parallel circuits different components are connected on different branches of the wire. If you follow the circuit diagram from one side of the cell to the other, you can only pass through all the different components if you follow all the branches.

In a parallel circuit, if a lamp breaks or a component is disconnected from one parallel wire, the components on different branches keep working. And, unlike a series circuit, the lamps stay bright if you add more lamps in parallel.

Parallel circuits are useful if you want everything to work, even if one component has failed. This is why our homes are wired up with parallel circuits.

IV. APPLICATIONTEACHER’S ACTIVITY

Provided with materials. Let the students assemble the four (4) essential parts of electric circuit. Instructions and safety rules must be discussed before the activity starts. The performance will be judge using the following criteria.

V. EVALUATION IDINTIFICATION:

O Direction: Identify the following items being asked in the sentence. Write your answer on the space provided.

1. It controls the flow of electrons.2. It provides pressure in the circuit.3. It allows individual to regulate electricity.4. It converts electricity into other forms of energy.5. It is a complete path where electricity flows.

ENUMERATION:O Direction: Enumerate the following items being asked.

1-4 Essential parts of electrical circuit.5- 8 Examples of load in electric circuit.8-10 Types of electric circuit

VI. ASSIGNMENT- In a ¼ sheet of pad paper, explain what will happen to the electric circuit if the

electricity will return to the source without passing the load. 10 pts.
