### 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.

### 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...
