# John Travolta

### Practical

Demo :

• Balloon to blow up to explain static electricity - show it sticking to the wall
• Use the tesla coil to show a "field" lighing up neons.
• Vandaar graaf
• Bubbles
• 2x Foil with leads (croc clips)

Practical:

11 x collection of cloth and plastic rulers

11 x coke cans for racing.

### Risk

Risk:

• Warn students of posibility of a small shock

## KS4 -P4.2 - Current and charge

# LIGHTENING strike

Charge Foundation

Charge Higher

Demo :

• Energy stick
• Rope
• Truck model

## KS4 -P4.35 Current - Practical

### Practical

Demo :

• Energy stick

Practical:

11 x

2 x Bulbs

1 x Spider Power supply

1 x Ammeter

## KS4 -P4.4 Voltage Theory

### Practical

Demo :

• string for rope model
• 1 x Bulb
• 3 x batteries

# Measuring PD

Sheet to take students though making circuits with cells in series and parallel.

### Practical

Demo :

• string for rope model

Practical:

11 x

1 x Bulbs

3 x cells

1 x Voltmeter

## KS4 -P4.5 Resistance

Resistance Foundation

Resistance Higher

### Practical

Demo :

• 1x
• Resistance wire (full length glowing across classroom)
• 3 x
• 2 x small diameter straw
• 1 x large diameter straw

For practical :

11x

• 1 x Variable resistors (large coiled ones)
• 1 x spider packs
• 1 x ammeter
• 1 x voltmeter

Students use the straws to model resistors, also if they are in parallel it is easier to blow

Students will then take various readings of a variable resistor to calculate the resistance at that point. (skills necessary for required practicals)

## Full RQ pract

### Practical

For practical :

11x

• 1 x Banjo boards (lengths of wire)
• 1 x variable resistor
• 1 x voltmeter
• 1 x ammeter
• 2 x croc clips

Students use measure the current and the voltage to calculate the resistance of the wire at various lengths.

## Higher

### Practical

For practical :

11x

• 12 V, 24 W filament lamp (eg a ray box lamp)
• 1x LED
• Resistor (eg 100 Ω, 1 W)
• variable resistor (eg 10 Ω, 5 A)
• 1 x voltmeter
• 1 x ammeter
• 2 x croc clips

Students use measure the current and the voltage to look at the characturistic of a component

For demo:

1x

• milliammeter (for working with the diode)
• voltmeter
• diode and protective resistor (eg 10 Ω)
• variable resistor (eg 10 Ω, 5 A)

## KS4 -P4.x Thermister

### Practical

Practical Thermistors

I-V graph of a thermistor

for all :

• 3x kettles for boiling water

11 x

• 1 x thermistor
• 1 x thermometer
• 1 x beaker
• 1 x voltmete
• 1 x ammeter

Students use the skills they have learned to show resistance changes with heat for a thermister.

### Risk

Care with boiling water
