I hope I can answer some of your question.

1.) I (my opinion) got interested in Titanic by watching the 1997 version of the movie.

2.) Well, even though I love the Titanic my career will be Movie Director. I decided to make this career when I was in the 7th grade. Probably 3 years ago.

3.)-------

4.) They should choose a american history(for americans only I guess), world history and any other type of history class. Also they should take any writing classes availble.

5.)------------

6.)They can work or be a help of a ocean or marine biologist center or group.

7.) I would suggest basically any Titanic book. Resources would be Titanic websites.

8.) If you mean where nobody can go down to see the Titanic. One word: Abserb.

9.)History classes if you go to college.

10.)----------

I hope I could been a little help. Sorry if I misunderstood any of your questions and made a mistake. Good, luck on your project.
