Resistors in series and parallel

Two videos for investigating resistance in series and parallel circuits. The first video demonstrates the experiment to measure voltage and current, and the second calculates the resistance values. This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics...

Resistance of a wire

Two videos investigating the resistance of a wire. The first video allows students to carry out an experiment on the resistance of a length of wire from home and the second evaluates the results by drawing a graph. This is a required practical students to be able to understand and carry out for GCSE Combined...

Refraction of light

A trio of videos that investigates the refraction of light through a transparent block.  This first video allows students to see the experiment and the other two review the results and plot a graph to investigate the relationship between the incident and refracted angles.  This is a required practical for students...

Reflection of light

This video demonstrates an investigation of reflection at a plane mirror.  This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.

Measure the power of a person and results

In this video clip the power of a person running up stairs is investigated. The subsequent calculations are explained.  

Lamps in series and parallel

A pair of videos that investigates the characteristics of lamps in series and parallel circuits.  This first video allows students to carry out the experiment and the second reviews the results.  This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics...

IV Characteristics of a diode

A pair of videos that investigates the IV characteristics of a diode. The first allows students observe the experiment, which is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.  The second explains how to interpret the data, plot the graph and...

Infrared radiation emitted

A pair of videos that investigates the emission of infrared radiation by different surfaces.  The first allows students to see the experiment undertaken and the second clip explains how to plot a graph to evaluate the relationship. This is a required practical for students to understand and be able to carry out for...

Infrared radiation absorbed results

This video clip demonstrates an investigation into the absorption of infrared radiation by different surfaces. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics.

Half-life of a model radioactive source

In this video clip radioactive decay is modelled using the rolling of dice. The data are plotted on a graph and the half-life is determined. 

Field around a magnet

This video introduces permanent magnets, their fields and how to investigate them using iron filings. It also demonstrates the field between attracting and repelling magnets. 

Extension of rubber

A pair of videos that investigates the extension of an elastic band when forces are added.  The first allows students to see the experiment undertaken and the second clip explains how to plot a graph to evaluate the relationship.

Extension of rubber

Extension of rubber results 

Extension of a spring

A pair of videos that investigates the extension of a spring when forces are added.  The first allows students to see the experiment undertaken. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics. The second clip explains how to plot a graph to...

Experimenting with a trolley

In this video independent and dependent variables are discussed, before experimenting with a trolley on an inclined ramp. The data is then graphed and analysed to investigate any relationship between ramp height and trolley speed. This is a GCSE Physics Practical.

Density

A pair of videos that investigates the density of different materials.  The first allows students to see an experiment on the density of regular and irregular objects from home. The second part outlines the calculations used to work out the densities of cylinders of different materials. This is a required practical...
