• Materials: Resistors of varying values, breadboard, audio source, oscilloscope.

• Procedure:

  • Create a simple circuit with a resistor and an audio source.

  • Use the oscilloscope to visualize the audio waveform before and after passing through the resistor.

  • Experiment with different resistor values to observe how they affect the amplitude, frequency, and overall shape of the waveform.

(Chorus)
Length of the wire, as it grows,
Resistance increases, that’s how it goes,
Thicker is better, area wide,
Less resistance, come take a ride.

(Verse 2)
Temperature's role, it can change,
Hotter it gets, resistance rearranged,
Metals rise high, while others may fall,
Keep it cool, we can have it all.

(Chorus)
Length of the wire, as it grows,
Resistance increases, that’s how it goes,
Thicker is better, area wide,
Less resistance, come take a ride.

(Bridge)
Oh, let’s explore, what we can find,
With every factor, we’re intertwined,
Material, length, and width in play,
Let’s calculate, and light the way.

(Chorus)
Length of the wire, as it grows,
Resistance increases, that’s how it goes,
Thicker is better, area wide,
Less resistance, come take a ride.

(Outro)
So remember these factors, keep them in mind,
Resistance is key, in circuits we find,
With knowledge we gain, we can be so bright,
Understanding resistance, it feels so right!

• Divide students into groups.

• Provide each group with a scenario involving toll booths (e.g., a traffic jam, a toll booth malfunction, or a new toll booth being added).

• Ask students to draw a diagram of the circuit (series or parallel) and explain how the scenario would affect traffic flow.
