I have outlined how I would approach this question below:
Given Apparatus: Lamp, Stopwatch, Meter Rule, Thermometer
Dependent Variable- Temperature of the surroundings
Independent Variable- Lamp Type
Control Variables- Distance of thermometer from lamp, Starting temperature, Time between initial and final measurement of temperature
The independent variable is what we are varying, and the dependent variable is what we are measuring.
These are the steps I would use:
1. Set up the apparatus using lamp 1 and take the starting temperature.
2. Turn the lamp on and start the stopwatch.
3. Record the temperature of the surroundings when the stopwatch reaches 5 minutes and record the difference between this temperature and the starting temperature (the difference is more reliable as the starting temperatures may be different).
Hi there,

2. Turn the lamp on and start the stopwatch.
3. Record the temperature of the surroundings when the stopwatch reaches 5 minutes and record the difference between this temperature and the starting temperature (the difference is more reliable as the starting temperatures may be different).
4. Repeat the experiment with the other lamps.
If you have any further questions please reply.
