New GCSE AQA Physics lesson on ’ Pressure in Liquids’ written in line with new AQA Physics specification. All questions provided with answers within power point. The lesson starts with a question on the dangers presented to deep sea divers. How liquids exert a pressure is demonstrated with a visual of a series of containers with different heights of liquid inside whilst highlighting the liquid has mass and therefore weight - this is then linked back to pressure = force/area. The importance of height in relation to pressure is further reviewed with a water bottle that has holes at different heights - the water jets shooting out is then discussed. Finally reviewing the importance of density to mass to weight and therefore pressure leads to the formation of the equation, P= ρgh - practice of the use of the equation is provided by looking at the pressure beneath the sea at different depths. The dangers of deep sea scuba diving are again discussed with the lesson knowledge gained. The lesson is concluded with a set of review question. Lesson Objectives: - Explain how a liquid exerts a pressure. - Explain how pressure exerted by a liquid can be increased. - Explain how pressure varies at different points in liquid. - Calculate the pressure in a liquid column.

New GCSE AQA Physics lesson on ’ Pressure and Surfaces’ written in line with new AQA Physics specification. All questions provided with answers within power point.

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.

New GCSE AQA Physics lesson on ' Centre of Mass' written in line with new AQA Physics specification. All questions provided with answers within power point.

New GCSE AQA Physics lesson on 'Moments, Gear and Equilibrium' written in line with new AQA Physics specification. ALL ANSWERS TO QUESTIONS INCLUDED IN POWERPOINT Starter poses the common question of how easy is it to open a door close to the hinge point which makes a very fun class demo and nicely leads into the lesson on moments, A variety of simple devices that make use of levers is shown to identify what they all have in common which highlight they all produce a great turning effect/force. Two experiments are provided to investigate either applied force and turning effect or distance from pivot and turning effect. This helps pupils identify the two contributing factors to moments and therefore the equation. A series of question practice use of the the moment equation. Balanced moments and equilibrium is explained in relation to a see-saw and then explained with the equation allowing for review question to be completed. An exam question is provided also. Further a small section on gears is included to relate the principles of moments to gears. Firstly pulleys are shown to make it more easily related to moments which is then directly shown with gears. The use of high gears and low gears with vehicles is explained. (I will revisit this aspect to integrate firmly into the main lesson). Lesson Objectives: - Define what is meant by a ‘moment’ and its units. - Resolve simple moment problems with the moment equation. - Explain how moments can be increased and how they can be useful. - Apply the principle of moments to gears and their uses. - Resolve moments in equilibrium.

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. Lesson Objectives: - Explain how displacement and distance are different. - Identify and explain scalar and vector quantities. - Identify different types of forces and how these can be represented. - Explain what the effect of simple force interactions will have on objects.

Starter ‘Car Wars’ looks at the test collision between an old and a new vehicle to stimulate discussion of collisions and safety - posing the question which car is safer and why? This is discussed and reviewed focusing on crumple zones and comparing how each car crumpled and why this is good (or for the old car, bad). Crumple zones, air bags and seat belts are detailed and discussed for common function - to increase impact time to decrease impact force. This concept is highlighted by exploring the physics mathematically. Review questions with answers are provided for the topic.
