Assessment ISA (PU 2.5) Light Dependent Resistors (Section 1) 1. Write down your hypothesis. Explain why you made this hypothesis. Hypothesis: When it is day there is more light hitting the LDR and so its resistance decreases and the light turns off. When it is night there is less light so the LDR has higher resistance and the light turns on.

Advantages: Basic compound light microscopes
