Divide students into teams and provide them with different resistor setups. The goal is to determine which resistor has the highest resistance by measuring the current and voltage using the ammeter and voltmeter. The team that accurately identifies the resistor with the highest resistance wins.

Investigate the Effect of Resistance on Audio Quality

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.

Resistance as a Traffic Jam: Simulate resistance using traffic cones or chairs to represent obstacles. Have students role-play cars moving through a traffic jam. Discuss how the density of traffic (resistance) affects the speed of movement.

Water Flow Analogy: Use a hose and a bucket to demonstrate the concept of resistance. Fill the bucket with water and allow it to flow through the hose. Place your hand over the hose to restrict the flow and explain how this is similar to increasing resistance in a circuit.

(Verse 1)
In a circuit, can you see,
Factors that affect resistance, oh so free,
Material's kind, conductivity,
Copper shines bright, it’s the key, oh yes indeed.

(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!

Activity:

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.
