Method FIRP
1. Measure and record the mass of the copper block in kg
2. Wrap the insulation around the block
3. Place the heater in the larger hole in the block
4. Connect the ammeter, power pack and heater in series
5. Connect the voltmeter across the heater
6. Use the pipette to put a small amount of water in the other hole
7. Put the thermometer in this hole
8. Set the power pack to 12 V. Switch on the power pack to turn on the heater
9. Record the ammeter and voltmeter readings. These shouldn't change during the experiment
10. Measure the temperature and start the stopclock
11. Record the temperature every minute for 10 minutes
12. Calculate the power of the heater in watts
13. Calculate the energy transferred (work done) by the heater
14. Plot a graph of the temperature in °C against work done in J
15. Draw a line of best fit
16. Calculate the gradient of the straight part of your graph
17. Calculate the heat capacity of the copper block
18. Calculate the specific heat capacity of the copper block
19. Repeat the experiment for the blocks made from aluminium and iron
Thermal insulation
1. Put the small beaker inside the larger beaker
2. Use the kettle to boil water. Put 80 cm3 of this hot water into the small beaker
3. Use a piece of cardboard as a lid for the large beaker. The cardboard must have a hole for the thermometer
4. Put the thermometer through the hole in the cardboard lid so that its bulb is in the hot water
5. Record the temperature of the water and start the stopwatch
6. Record the temperature of the water every 3 minutes for 15 minutes
Activity 1: How does the length of the wire affect the resistance at a constant temperature?
1. Use the circuit diagram to set up and connect the circuit
2. Connect a lead from the negative side of the ammeter to the crocodile clip at the zero end of the ruler
3. Connect a lead from the other crocodile clip to the negative side of the battery. Use this lead as a switch to disconnect the battery between readings
4. Decide the interval distance (eg 10cm) you will investigate and connect the first distance to be tested between crocodile clips A and B
5. Measure the readings on the voltmeter and ammeter at this distance
6. Record your results in a table
7. Move crocodile clip B and record the readings for the different distances
Method 
1. Use the circuit diagram to set up and connect the circuit for two resistors in series R1=R2
2. Switch on and record the readings of the ammeter and the voltmeter
3. Calculate the total resistance of the series circuit.
• in series, total resistance = sum of resistors
Method 
1. Set up the circuit for two resistors in parallel. Use the circuit diagram below
2. Switch on and record the readings of the ammeter and the voltmeter
3. Calculate the total resistance of the parallel circuit.
• In parallel total resistance< value of lowest resistor
I-V characteristics method
use circuit with A and V with variable resistor
record readings
change p.d. on variable resistor and record again
repeat to collect multiple readings
swap connects of battery supply (ammeter in Negative terminal and VR in positive)to make readings negative
find more readings
plot of graph, draw line of best fit
should show results of filament lamp
repeat with diode and resistor
