This PowerPoint resource is perfect for teaching the concepts of thermal energy transfer through convection and radiation. Designed with clarity and interactivity in mind, it includes: Starter Activities: Thought-provoking questions to activate prior knowledge about heat conductors and insulators. Learning Objectives: Clearly defined goals to help students understand convection currents, describe radiation, and differentiate between heat transfer methods. Detailed Explanations: Step-by-step breakdowns of convection and radiation with real-life examples like heating in homes and energy transfer in space. Interactive Tasks: Gap-fill activities, question prompts, and diagram-drawing exercises to consolidate learning. Demonstrations: Visual examples and experiment-based questions to bring abstract concepts to life. Ideal for secondary school science lessons, this resource supports active learning and engagement.

Learning Objective: Investigate which materials are good insulators of heat. Method: Set up your boiling tubes: leave one unwrapped and wrap each of the others in a different material, using elastic bands or tape to hold the material in place. Try to make the different wrappings roughly the same thickness. Prepare lids for the containers, made out of the same material as the wrapping, if possible, otherwise made from aluminium foil or cling film. Make a hole in each lid which is just big enough for the thermometer to fit through. Use the measuring cylinder to pour 20ml of hot water into each boiling tube. Put the lids onto the containers, with a thermometer fitted through each lid so that it rests near the bottom of the water. Start the stopwatch and measure the starting temperature of the water. After 15 minutes, measure the temperature of the water in each beaker.

Describe the difference between balanced and unbalanced forces and give examples for both. Identify and calculate resultant forces. Describe situations that are in equilibrium. Explain why the speed or direction of motion of objects can change.

• Define what the centre of mass is and identify where it would be in a range of simple shapes. • State that a suspended object will come to rest so that the centre of mass lies below the point of suspension. • Describe an experimental technique to determine the centre of mass of an object with an irregular shape. • Compare the stability of objects to the position of their centre of mass.

Define elastic and non-elastic deformation in materials. Calculate the extension (or compression) of a material using its length and original length. State Hooke’s law and use it to calculate the force required to cause a given extension in a spring using the spring constant. Describe how elastic potential energy is stored when a material is stretched or compressed by a force. Describe force-extension graphs of elastic materials and identify the limit of proportionality. Compare the behaviour of different materials before and after the limit of proportionality.

Learning objectives: Describe the difference between scalars and vectors. List some common scalars and vectors. Draw a scale diagram to represent a single vector.
