Telling the story
Like there were many who did not have a clue about Titanic before watching the movie, there will still be many who may not have heard about the Titanic movie either. If your kids fall in much the same category, you can tell them the story behind Titanic which can prove to be something of great interest for them.
Watching the Movie
However, if you're not a good narrator, then you can easily find CDs and DVDs of the Titanic movie in the market. This will let the young kids visualize the incident and at the same, they will be able to remember it.
Remembering the people on board
It should be remembered that many people who were onboard the Titanic lost their lives as a result of the disastrous incident. One good thing to do as part of celebrations on this day is to remember those people. There can be a gathering or you can simply light a few candles somewhere in remembrance of people who lost their lives in this unfortunate incident.
