Hi, a black hole is an object in space with such tremendous gravitational force that nothing escapes from it, not even light. For your presentation, you can get ideas from the links below. These links will take you to NASA's website, where they cover a lot of ground on the topic of black holes. They even have animations that show you what black holes theoretically look like. However, I would advise that you take these animations with a grain of salt. Most animated depictions of black holes out there are in 2-D, when in fact, a black hole is supposed to be a 3-D thing.

A black hole is a bit like a gravitational whirlpool in space.
When a massive star collapses in on itself, not even light can escape its gravity. That is why a black hole is "black". The star's escape velocity is greater than the speed of light.
If you really want to have fun with this project, and learn a lot at the same time, check out what Stephen Hawking has to say about black holes, and why they may not actually be "black"...very interesting.

I saw a couple of black holes walking down Halsted Avenue in Chicago. What do you want to know about them?

The you probably need to start some serious searching.

How serious? Who's your target audience?

sometimes it comes from dying stars with such gravitaional force that even light cannot escape from it..
