Good luck on your project. But, I'm afraid you are in for a big surprise. If you ask an active JW these questions, you will receive carefully crafted canned answers, many of which are specifically designed to deceive.
JW's are expert liars (as ALL of us here were at one time as well) and employ words that have more than one meaning. As long as they themselves are thinking of an obscure (or our-of-context) meaning they have no problem lying to you by using loaded language; knowing that you will almost always accept the common meaning. They don't consider this lying because they can always claim they were thinking of the obscure meaning. Of course, that is total bull-crap..
For example, if you ask a JW if they celebrate the Lord's Supper where the wine and the bread is consumed, they will answer, "Of course, who told you that we didn't"? If you press a little further and ask something like, "Is it true that most JW's refuse to participate in this command of Jesus"? They will simply smile and act like that you have been terribly misled and then say something like, "That is ridiculous, ALL JW's observe the Lord's Supper ceremony, we call it the Memorial".
The word "observe" has more than one meaning. The meaning that they hope you unquestioningly accept is in the sense of celebrating a customary holiday. If someone says that they observe Thanksgiving and Christmas every year at their In-Laws' house, you immediately get a picture of Turkey dinners and gift-giving, since those are customary practices of those holidays.
But the JW doesn't use the word "observe" in that sense. The meaning that the JW has in his head while trying to deceive you is the out-of-context meaning of observation, ie. looking-on, watching, perceiving etc.
The above image is of a JW Lords Supper ceremony in 2013. All JW's gather together and the bread and the wine is passed to each individual. Virtually every JW disobediently rejects the bread and the wine that Jesus said was for the forgiveness of their sins (Mt. 26: 27-28) and commanded all to receive.
Each of the JW's "observes" the sacraments being passed (and rejected) from hand to hand until they reach him where he also rejects them as he passes them down the row. All this the JW sees.... or observes.
So the JW can claim that he was not lying to you by stating that all JW's observe the Lords Evening Meal. But the reality is that instead of participating in the celebration, each JW actually does the opposite by ritually rejecting the Lord's Evening food and drink.
A long speech is given beforehand instructing people to reject this covenant with Christ for the forgiveness of sins.
Welcome to the whacky wide-world of Watchtower deception. Talking to a JW is like walking into a house of mirrors.
Again, good luck with your project. But, if you determine at the end of your project that JW's are just another Christian sect, you will have been played. Probably by the best that is out there.
