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.

This PowerPoint resource provides an interactive approach to teaching the concepts of heat transfer, energy efficiency, and insulation. Perfect for secondary school science classes, it includes: Starter Activity: Review key heat transfer concepts with targeted questions on conduction, convection, and radiation. Big Questions: Investigate how heat is lost from homes and how insulation helps reduce costs and energy waste. Detailed Explanations: Explore real-life applications of heat transfer, including loft insulation, cavity walls, radiator reflectors, and double-glazed windows. Practice Problems: Include payback time calculations to analyze the financial and environmental benefits of insulation. Interactive Tasks: Fill-in-the-blank activities, practical questions, and opportunities to reflect on energy-saving strategies. This resource is designed to support student understanding of thermal energy transfer and encourage critical thinking about sustainable living.
