For example: - Newton often forgot to eat food.  - He never married. In spite of discovering gravitation, he never “fell” in love. - Newton was a center point in the climax of blockbuster novel/movie – “Da Vinci Code”. Tell them interesting trivia about topic you are teaching. Like: - Astronauts cannot cry in space. Gravity pulls the water from your eyes down to earth and so you cry, if you are in space or on a planet there wouldn't be enough gravity to allow you to cry. “Good artists copy; great artists steal”. Don’t be afraid to show content from internet. There is ton of free interesting quality stuff on internet.

If you are teaching Gravitation, don’t just limit to physics. Rather tell them some interesting stuff about Newton. Everybody likes stories. Don’t just tell what’s in text book, give them full story
