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.

iGCSE - Acceleration calculations and graph interpretation This lesson covers the basic calculation of acceleration, and then uses graphs to show calculations using gradients as well as the area under the graph using composite triangles and rectangles. The worksheet is a two page questions sheet (with answer sheet supplied) that goes over the main points covered in the lesson

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.

iGCSE - Reflection of light This lesson covers the basics of reflected light, honing in on exam points including the normal and the angles of incidence and reflection. The experiment for reflection of light and a ray box is included, as well as description of specular and diffuse reflections and how to draw diagrams with multiple reflections from surfaces.

This lesson covers the basic calculation of velocity, defines velocity and speed, covers the main units of measure and then uses graphs to show calculations using gradients. The PowerPoint is animated and is designed to show worked examples of how to find a gradient step-by-step for both a straight line and a curve. The worksheet is a two page questions sheet (with answer sheet supplied) that goes over the main points covered in the lesson

This PowerPoint goes through the mathematics needed to calculate Kinetic, Work Done and Gravitational Potential Energy. It builds on and reviews velocity calculations. There are two versions of a step-by-step object on a slope experiment which will enable pupils to test the equating of the formulae for Kinetic energy and Work Done and utilise this for calculating braking forces due to friction.

iGCSE Physics PowerPoint that covers the topic of Work Done. This 14 page powerpoint explains how frictional forces, including air resistance, needs to be overcome to keep an object moving. This is investigated with two practicals (one looking at surfaces and the second similar / extension practical looking at the effect of changing the weight of the object on friction). Graphing skills with extrapolation are also highlighted. This is the fourth of 6 topics in this units of work and is aimed at covering approximately 2-3 hours of teaching, including the experiments.

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.

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 Physics PowerPoint that covers the topic of Energy including: Energy stores, energy forms, energy transfers, two practical lessons with methods and analysis, conservation of energy, and energy efficiency calculations. This is the first of 6 topics in this units of work and is expected to cover approximately 3 hours of teaching. v1.1 - Added Sankey diagram slide and a second summary slide

This lesson covers the Evidence of the Big Bang through inlcluding the calculation of recessional speeds due to the Doppler Effect and an explanation of the Cosmic Microwave Background (CMB). There is a worksheet of questions and answers included in this lesson. This is the sixth and final lesson in this section entitled “Astrophysics” which is available as a bundle in our shop.

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.

This lesson covers both the apparent and absolute magnitude of stars, brightness and luminosity, the logarithmic scale and the Hertzsprung-Russell diagram. The H-R diagram includes the positions of the main stellar types, the Sun and the evolutionary path of the Sun. There is a worksheet of questions on these topics, including an answer sheet. This is the fourth (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop.

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

This PowerPoint lesson on The Universe covers the introduction of what is in the universe and what we can see and measure in the night sky (planets, stars, asteroids, galaxies etc.). There is also a set of questions and answers. This is the first (of 6) lessons in this section entitled “Astrophysics” which is available as a bundle in our shop.
