Your challenge is to explain today's topic clearly enough for someone unfamiliar with it to understand.
Understand it first. Take a moment to think about what the topic really means. What's the most important thing someone needs to know?
Keep it simple. Explain the idea aloud using ordinary English. Avoid technical terms and unnecessary details. If you must use an unfamiliar word, explain what it means.
Make it memorable. Use an everyday example, comparison or analogy to help your listener understand.
Imagine you're explaining the topic to an intelligent person who knows very little about it. Don't talk down to them!
Extra challenge: Try explaining the same idea in 30 seconds. Can you make your explanation shorter without losing anything essential?
If you find yourself struggling to explain something clearly, that's useful information. You may need to understand the idea more deeply before you can communicate it effectively.
