Back to topicsTips for teaching physics with PowerPoint
- Start from real life. Open with an everyday example, such as braking distances, a phone charger or a rainbow, before the theory.
- Build equations step by step. Reveal one term at a time and explain what each symbol means before putting numbers in.
- Use diagrams, not paragraphs. Force diagrams, circuit symbols and wave sketches teach more than bullet points.
- Add worked examples and practice questions. Walk through one problem, then give students a similar one to try.
- Mix in simulations and video. Short demonstrations or virtual experiments help with ideas that are hard to show in the lab.
- Finish with a summary slide. Recap the key points so students have something to revise from.
