2 New GCSE AQA Physics lesson on 'Infrared Radiation & Black body radiation' written in line with new AQA Physics specification. Bundled together is 2 complete lessons on infra-red radiation with different learning objectives and activities. LESSON 1 - Infrared radiation and black body radiation Lesson starts with optical illusion which makes white dots appear black, this is to start thoughts on what black is and engage students with something a bit different. The difference between heat and temperature is discussed to lead to what infrared radiation is. A question posed about whether ice gives off infrared radiation consolidates a key point. Thermal imaging is explored with how it works and a guess what it is exercise of infrared images. Different shades of black are shown to discuss what black does in terms of visible light, leading to an explanation of perfect black body radiation. Black body radiation and infrared emission at varied temperatures is discussed (including a link to a useful simulation). The effect of absorption and emission of infrared on bodies is detailed concluding with summary question on the topic. Lesson Objectives: State the difference between heat and infra-red radiation. Explain what is meant by ‘black-body radiation’. Identify the effects of infra-red radiation can have on a body. Relate the effects of absorption and emission of infra-red radiation has on a body. LESSON 2 - Infrared radiation, surfaces and bodies The use of black balls on the LA reservoir is shown in gif images to pupils to discuss why they did this. Absorption and emission of infrared is reviewed briefly. This leads to factors which effect the Earth's temperature and how greenhouse gases impact this. An experiment to investigate different surfaces and infrared emission, absorption and reflection is outlined. The key points from this investigation are summarised for note taking. A true or false activity reviews previous content followed by review questions. Infrared emission, absorption and reflection is applied through questioning to the Earth & the moon, satellites in space and the starter on the LA reservoir. Lesson Objectives: Identify and explain key factors that effect the temperature of the Earth. Investigate and identify the properties of different materials and their effect on infra-red radiation. Apply your knowledge of infrared radiation and surfaces to real life problems. Explain why the temperature on the Moon is different to the Earth.

New GCSE AQA Physics lesson on 'Internal Energy' written in line with new AQA Physics specification. Lesson Outline: Starter discussed whether a glass of water has energy of not to see what conclusions pupils can draw on this from previous lessons. This leads to a view of a substance on a microscopic scale to highlight that the particles are moving, therefore pupils should be able to deduce must have energy in order to move. Internal energy is then shown to be this energy in substance due to kinetic energy and potential energy. After revisiting the starter how to increase internal energy is discussed The different states of matter are review again but now in relation to internal energy with helpful graphics to support these points. How much energy in a substance is related to specific heat capacity which is typically covered earlier in the course so this provides a great opportunity to review of this topic. Lesson concludes with review questions.

New AQA GCSE lesson on Scalars and Vectors (+ Forces) written in line with new GCSE AQA specification. All questions provided with answers within power point. Starter asks how far away a school is from a home - this prompts responses from pupils that either follow the road or straight across the field. This introduces the idea of distance and displacement which is explained in detail. This is also used to explain magnitude, scalars and vectors. A series of questions review pupils understanding of distance and displacement. A quick class activity reviews a number of different variables to classify each as scalar or vector. Speed and Velocity are identified as a scalar and vector by reviewing the equations and then also related to acceleration. This leads to force the representation of force vectors and scale diagrams. A quick review of forces and different types of forces lead to force interactions and their effects. A set of review questions provides use of force vectors.

New GCSE AQA Physics lesson on ' Resolution of Forces' written in line with new AQA Physics specification. All questions provided with answers within power point. The starter provides some simple combination of forces questions to review the subject of resultant forces - one question has two forces acting on different planes which pupils will be unfamiliar with and therefore how to solve - this prompts the lesson. The intuitive resultant force and direction is highlighted but also how we need to calculate exactly what they are. The parallelogram/geometric method is taught step by step with a worked example, this is done a second time with another example but with the class prompted to follow it and do the same on their own paper which also allows for discussion of difference in results. A collection of questions allows pupils to practice use of this method. This method is then used for inclined planes to explain frictional force acting to put object in equilibrium on inclined planes. Review questions again allow pupils to practice this. Lesson Objectives: - Review resolving simple combination of forces. - Identify when forces are acting on different lines/planes. - Calculate the resultant force on an object which has equal forces acting on different lines/planes. - Calculate the resultant force on an object which has unequal forces acting on different lines/planes. A worksheet is not provided as it is best for pupils to work on their own paper to define their own scales for this methodology.

For starter different plugs from the around the world can be put in bags to be passed around or a dismantled plug. Pupils are to guess what is in the bag. Following this pupils are to discuss why there are different types of plugs around the world which lead to discussion of the AC/DC war between Edison and Tesla (this part of the lesson can be easily removed if not suitable for the class). The anatomy of a plug is shown and explained in detail for all 3 wires, colours and function. Safe wiring of a plug is reviewed which leads to a class activity to wire plugs safely.

Density is then clearly explained with visual effects to provide an example with a definition. Volume is also explained with comparative visuals. This lead to density being considered with volume and then both considered to produce mass - leading m=ρV. Some review questions practice the use of this equation. Pupils are tasked with finding the density of different objects provided by the teacher (simple shapes of common materials required). REQUIRED PRACTICAL 5 To continue the lesson the story of Archimedes and the gold crown is told featuring some key questioning for pupils. This then leads to pupils finding the density of irregular shaped objects by ‘displacement technique’ (REQUIRED PRACTICAL 5).

New GCSE AQA Physics lesson on 'Energy and Efficiency' written in line with new AQA Physics specification. The lesson can start with either a task to correct statements provided about energy or to discuss what happens to wasted energy. Different types of bulbs are shown through images which pupils are likely to have comes across, they are then prompted to discuss how they are different and why we use different ones, this lead to talking about efficiency. Useful and wasted energy are explained and related to context and energy flow diagrams previously used. Also a key explanation of what happens to wasted energy is given. Pupils must then identify whether particular energy changes are useful or wasteful for certain devices. Energy efficiency is detailed to students and then presented as 'units of energy' in a form similar to sankey diagrams (which are no longer required by AQA but can help students rationalise percentages). A class activity is outlined which requires groups of pupils to shown how energy is split by different devices and can help students visually see how portions of energy are distributed. Following this the energy equation is given which is then used by two sets of review questions. The lesson concludes with content for higher tier students which looks at ways energy waste can be reduced. Lesson Objectives: 1) Explain what is meant by useful and wasted energy. 2) Explain what eventually happens to wasted energy. 3) Calculate the energy efficiency of different appliances. 4) Detail how energy transfers can be made more efficient.
