Figure 1 shows the apparatus a student used to investigate how the resistance of a Light Dependent Resistor (LDR) changes with light intensity. The student varies the distance between a filament light bulb and the LDR.

Figure 1: An LDR experiment showing a filament bulb connected to a power supply, a metre ruler, and an LDR connected to a multimeter. Background light is shown shining on the LDR.

Explain one improvement to the apparatus or method that would improve the accuracy of the resistance measurements.
