This GCSE Physics PowerPoint presentation provides a detailed lesson on the required practical for investigating the absorption and emission of infrared radiation. Designed for AQA GCSE Physics, this resource explains how different surfaces emit and absorb infrared radiation at different rates. The lesson includes step-by-step practical guidance, real-world applications, and exam-style questions to develop students’ understanding of heat transfer by radiation.
Infrared radiation is a type of electromagnetic wave that transfers thermal energy. All objects emit infrared radiation, and the amount emitted depends on the surface color, texture, and temperature. This lesson focuses on investigating how different materials absorb and emit infrared radiation, using a Leslie cube and boiling tubes to compare heat loss across various surfaces. Students will learn how black and matte surfaces are better absorbers and emitters, while shiny and white surfaces reflect radiation more effectively.
The PowerPoint provides a detailed method for the required practical, including the use of a Leslie cube or boiling tubes filled with hot water. It outlines the equipment needed, risk assessment, and fair testing considerations. Students will record temperature changes over time to determine which surfaces emit heat most effectively. They will also analyze results by constructing bar charts and evaluating experimental errors, reinforcing their ability to interpret scientific data.
The fully editable PowerPoint (.pptx) allows teachers to tailor content to suit their teaching needs, making it a valuable resource for classroom instruction.
