For GCSE Physics, a good way to teach is by mixing experiments with videos and discussions. Start each class by talking briefly about what you'll learn. Then, do experiments to show how things work in real life. Let students join in and try things out themselves. Talk about what happened and why. Use videos and pictures to make things clearer. At the end of class, summarize what you've learned and talk about any questions. This way, students can understand the ideas better and have fun while learning.
