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...

A pair of videos that investigates the specific heat capacity of a liquid.  This first video allows students to carry out an experiment on the specific heat capacity of water from home. The second explains how to interpret the data, plot the graph and determine the specific heat capacity of water.  This is a...

A trio of videos that explains how to determine the specific heat capacity of a metal.  This first video allows students to see the experiment and the other two review the results and plot a graph to determine the specific heat capacity.  This is a required practical for students to be able to understand and carry...

In this video an oscilloscope simulator on a laptop is demonstrated to visualise a sound wave and calculate its frequency. 

This set of demonstrations into the effects of tropisms on seedlings is both simple and extendable. Seeds sown on damp cotton wool in Petri dishes are grown either flat, or stuck vertically to a wall, showing the different effects of gravitropism. After a week, students...

This video investigates the temperature–time relationship for melting ice. A graph to show the change of state is plotted. 

The terminal velocities of cupcake cases are calculated in this video and a graph of mass versus terminal velocity is plotted to investigate the relationship. 

In this activity developed by the Institute of Physics, students investigate how temperature changes with distance from a heat source and relate this to planetary temperatures. After completing this activity, students should be able to:

*Understand that the temperature of a planet depends on its distance...

In this activity, developed by the Institute of Physics, students use a lamp and polystyrene balls to model how astronomers detect exoplanets using the transit method. After completing this activity, students should: *Understand that the transit of a planet in front of its star temporarily reduces the star’s...

A pair of videos that studies the thermal insulation properties of bubble wrap. This first video allows students to see an experiment that investigates how increasing the number of layers of bubble wrap around a beaker affects the cooling of hot water. The second explains how to interpret the data, plot the graph...

The properties of a transformer are investigated in this video, specifically how the number of turns on the coils affects the output. 

This video demonstrates a simple experiment to investigate the principle of moments.

The speed of a wave in a solid is investigated in this video. A signal generator and length of elastic are used to measure the frequency and wavelength of a wave, which allows wave speed to be calculated. 

A ripple tank is used in this video to calculate the speed of a water wave by measuring the distance and time. This is a GCSE Combined Science and Physics Required Practical.
