English National Curriculum - Science
Mission Objectives
Investigate how the resistance of an LDR changes with light intensity
Investigate how the resistance of a thermistor changes with temperature

Words and meanings to learn
thermistor
a type of resistor whose resistance decreases as temperature increases (NTC type) or increases as temperature increases (PTC type); used in temperature sensors and controlling devices like fans or ovens
resistance
a measure of how much a component opposes the flow of electric current, measured in ohms (Ω)
control variable
the variable(s) kept constant in an experiment to ensure a fair test
LDR (light dependant resistor)
a type of resistor whose resistance decreases as the light intensity falling on it increases; used in devices such as street lights, cameras and security systems
fixed resistor
a resistor with a set resistance value that does not change with conditions like temperature or light; used to limit current in a circuit
