This lesson starts with a recap on how to use radians, before moving onto linear and angular displacement and then angular velocity. Regular learning checks throughout the lesson. Questions come with worked solutions. Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 onwards specification, but is also applicable to other specifications such as the UK AQA one.

This lesson on Gas pressure covers what causes pressure in a gas, as well as causes of changing pressure, such as changes in temperature, volume and quantity (mass) of gas. The video introduces Boyle’s law, where PV is constant and P1V1 = P2V2. Past paper IGCSE exam questions are used throughout. All questions come with answers or full worked solutions. A shortened version of the lesson can be found on YouTube.

This lesson covers why we have seasons, with a variety of tasks and questions, all with solutions. This is a full lesson. Designed for the new Cambridge checkpoint specification but can also be used with UK and other curriculum.

This lesson on Stellar Radii covers Black body radiation, the relationship between colour and temperature, leading into Wein’s displacement law and Stefan-Boltzmann’s law and using both to estimate the radius of a star. Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with worked solutions

This lesson on Polarisation covers what is meant by the term polarisation, how polarising filters work, and how intensity varies as a filter is rotanted (Malus’s law). Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with answers or full worked solutions.

This lesson covers why we have day and night, with a variety of tasks and questions, all with solutions. This is a full lesson. Designed for the new Cambridge checkpoint specification but can also be used with UK and other curriculum.

This lesson covers a recap of diffraction from GCSE, followed by looking at interference. We then look at Youngs double slit experiment, before the students perform it themselves, in an attempt to find the wavelength of red or green light (will need laser and double slit grating for this, along with a long tape measure) Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with answers or full worked solutions.

This lesson looks at standing waves in closed end tubes, showing where nodes and antinodes are formed. It then moves on to a practical task, in which students determine the speed of air in sound (equipment required = tube, 250ml measuring cylinder and a mobile phone). Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with answers or full worked solutions.

This lesson on stationary waves compares stationary waves to progressive waves, and describes and explains key features of standing waves. It also explores hormonics on a vibrating string. Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with answers or full worked solutions.

This lesson covers a recap on absorpion/emission spectra and doppler effect before moving on to red shift, the expanding universe, Hubble’s law and the big bang theory. Designed for Cambridge (CIE) unit 9702, for 2022 onward and 2025 specification. All questions come with solutions
