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.
