A worksheet that examines the electrical resistance of: Thermistors at different temperatures, Light-Dependent Resistors (LDRs) at different light levels. The current-potential difference (current-voltage, I-R) graph for a thermistor at three different temperatures is analysed through structured questioning. Resistance is calculated using Ohm’s Law. Data of resistances at varying temperatures for a thermistor is presented and students are asked to plot the graph and describe the pattern shown. A plotted graph of resistances for varying light levels for an LDR is presented and students are asked to draw a line of best fit and describe the pattern shown.

A 7 page booklet which, when printed to A4, provides templates for the shining of light into a glass or Perspex block at regular incident angle intervals of 10 degrees. The first page has full experiment instructions and a drawn example. The block outlines are drawn to match what appears to be the standard size of rectangular Perspex block found in every school I have worked in! This booklet will save you time: students will not have to draw around the blocks, or draw the initial incident ray on the top surface. They can therefore focus on measuring and recording the angles made by the light as it passes through the block.
