iGCSE - Total Internal Reflection This lesson covers the refraction of light and the calculation of refractive index as applied to the phenomenon of total internal reflection. This lesson also demonstrates the experiment that can be performed, step-by-step with animation.

This lesson covers the Evolution of the Universe from the Big Bang through all of its major stages, including particle creation, primordial fusion and the development of galaxies. There is a worksheet of questions and answers included in this lesson. Please note that the theory of the Big Bang and the evidence for it is covered in the next lesson of this series. This is the fifth (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop.

iGCSE Physics PowerPoint that covers the topics of conduction and convection. This 18 page powerpoint explains the two methods of thermal transfer, goes through a science classroom experiment for each and links to insulation with a third experiment fully explained. There are also links with weather patterns and a discussion of the four variables that control conductive transfer rates. This is the second of 6 topics in this units of work and is aimed at covering approximately 3 hours of teaching, including the experiments.

iGCSE - Refraction of light and refractive index This lesson covers the refraction of light and the calculation of refractive index when passing from air into transparent materials. This lesson also demonstrates the experiment that can be performed, step-by-step with animation. There are also two examples of light entering and exiting other shapes (prism and edge of a square) which can cause pupils issues in exams.

This is a 7 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Tensile and Compressive forces which create stress and strain. This then goes on to explain how this relates to the Modulus of Elasticity (Young Modulus). Three question sheets are included complete with worked answers. This is the first of three PowerPoints in this series and covers the mathematical and physics for an analysis of Stress and Strain in Engineering materials v1.1 - PDF question sheets and worked answers added to resource v1.11 - Two more sets of questions and answers added to resource; minor improvements to ppt also made v1.12 - Error on the answer sheet corrected v1.13 - Jan 2023 Error on Powerpoint corrected

This is the first of three lessons that introduce the idea of logarithms The PowerPoint takes students through the difficulties in graphing data of wide ranging numbers and then, using the E-M spectrum and H-R diagrams, shows how log-log graphs can be used to display this data. This is part of the essential mathematics skills needed for A-Level Physics

This PowerPoint lesson on Stellar Evolution covers the development of a star through its entire life. This powerpoint includes the iGCSE details linking surface temperature to the colour of star and the ultimate ending paths of stars depending on their mass. A poster / flow chart activity idea is also included. This is the third (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop.

This PowerPoint lesson on Orbits and Orbital Motion covers the mathematics of circular motion (at iGCSE physics level) and applies this to the orbits of the planets, moons and satellites. Various types of satellite orbits are also considered including geostationary orbits. This is the second (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop

iGCSE Physics PowerPoint that covers the topic of thermal radiation. This 14 page powerpoint explains how thermal radiation (infrared) is absorbed and emitted from different surfaces. Two experiments are explained in detail as well as the results from the Leslie cube demonstration including a FLIR photo. A vacuum flask diagram is also explained and links back to the previous lesson on conduction and convection. Common misconceptions are also highlighted. This is the third of 6 topics in this units of work and is aimed at covering approximately 2-3 hours of teaching, including the experiments.

This is lesson 17.2 Centripetal Acceleration from the latest syllabus Included here is a powerpoint of this lesson and lesson plan complete with point by point teaching, homework recommendations and curriculum links. Everything that you need to teach this lesson. I am currently rolling out these lessons as I produce them and will bundle them together once each chapter is done. Please also see my Year 1 resources. All of Chapter one is free to sample and the entire 80 powerpoint course and detailed scheme of work is available on TES

This is a lesson and PowerPoint introducing the history and development of the model of the atom. This is the third lesson in the Atomic Structure unit of work (P4). The lesson covers the main scientists that have built up the theory of the atom over the centuries. The idea of theories and how they are developed and refined is discussed and some ideas for classroom activities are also included.

This is a lesson and PowerPoint that covers supernova (Type II and Ia), light curves and hydrogen lines of supernova, black holes (Schwarzschild radius calculations and Chandrasekhar limit), gamma ray bursts and the overall luminosity of these events. As well as supporting A-Level Physics for many exam boards this lesson is also part of a chapter that covers the optional astrophysics unit 9 for AQA
