Objective:
To create an interactive working model that helps students understand and match different types of verbs (e.g., action verbs, linking verbs, helping verbs, etc.) using LED lights, a 9V battery, a buzzer, and conductive materials.

Materials Required:
- LED lights (different colors for added visual appeal)
- 9V battery and battery clip
- Buzzer
- Nails or conductive pins
- Wires (to connect the circuit)
- Cardboard or wooden board (as the base)
- Printed or handwritten examples of types of verbs
- Labels for types of verbs (e.g., Action Verb, Linking Verb)
- Resistors (to protect LEDs)
- Copper tape or conductive wires for connections
Steps to Build English Grammar Working Model on Types of Verbs:
- Prepare the Board:
- Divide the board into two sections:
- Left Side: Types of verbs (e.g., Action Verb, Linking Verb, Helping Verb).
- Right Side: Examples of sentences demonstrating these types (e.g., “He runs fast” for Action Verb, “She is happy” for Linking Verb).
- Divide the board into two sections:
- Set Up Nails or Pins:
- Insert nails or conductive pins under each type of verb on the left side and each sentence example on the right side.
- Create the Circuit:
- For each pair (type of verb and its example):
- Connect the nails using wires.
- Include an LED and a buzzer in the circuit.
- Use resistors to limit the current for the LEDs.
- Connect all circuits to the 9V battery.
- For each pair (type of verb and its example):
- Ensure Match Concept:
- Only the correct match (e.g., “Action Verb” to “He runs fast”) should complete the circuit. Use diodes or unique wire paths to prevent incorrect matches.
- Test the Connections:
- Ensure that:
- Correct matches light up the LED and sound the buzzer.
- Incorrect matches do not complete any circuit.
- Ensure that:
How It Works:
- Students connect a wire or clip from a type of verb on the left to its matching example on the right.
- Upon a correct match:
- LED lights up and buzzer sounds, providing feedback.
- Incorrect matches produce no response.
