Chess varients - Bughouse, Losers, Atomic, etc...
Other games - Backgammon, checkers, go, etc...
Show them some high quality chess games, annotated.
Chess lessons can be interesting in moderation.
Organize a trip to a tournament, or an exhibition game (tricky, but worthwhile)
Give your club a breather from chess and order pizza or something.
i think that maybe u should see what they like and compare them together while you teach. 
I coach kids in schools. If you can get them into Chessmagnetschool.com and have computer access, they will find their games becoming better, hence, more interesting. It is free for 30 days. And, a fairly moderate fee after that. Their advertisement has been in Chess Life. They begin earning titles like: Squire, Duke, etc. The advancement to different levels becomes competitive amoung them. If the player who is bored and constantly losing spends enough time on it, he will soon be the top player. I have seen it happen. If your chess time is 60 minutes, spend 30 in the computer lab and play the rest of the time. Their training sessions can also be added to at home, the records are kept at the web-sight and all add up.
Also, go to a local scholastic tournament as a team. You would enter K-!2. They will propably get brused and then it is time to motivate them to improve.
That is a good idea, I have tried the tournaments in the past and there was no interest, really there is no one that is really interested in the game, they are all bad players and losing has affected them just a little too much, the advisor said I came a little to late and the only way to get them motivated is to have them win, but they are too depressed to learn, so it is a lose-lose situation.
Hi Teacher
Differ your approach in your method of teaching...by letting them read assorted art works with a little clash on eastern philosophies and meditations. Create a story telling from the chessmen castles knights and queens, creating problem solving puzzles on the positions. Tell your students that actual facts of life can be solved with stronger focus of analytical problem solving system. Try anything that will arose their interests however before teaching change your own attitude from positive thinking to positive knowing of what you are doing. Meaning to have stronger faith in your own capacity in teaching Chess.
Goodluck !!!

Eddie, did you read Josh Waitskin's book The Art of Learning? It would fit in to your proposal. Get the kids to read that and have them relate to the subtleties of any learning, especially chess and martial arts as he did. He ended up being a world champion in his specialty in four years! He couldn't stand how he was treated at chess tournaments after Searching for Bobby Fischer.
Do you suggest the Gita or some Vedas, maybe prana yoga or TM? A little deep for bored high schoolers. Actually, you could develop a story about Arjuna and God awaiting the battle of the black and white pieces: Who would attack first? What were their motives for fighting? Who would be defensive? What men would they use and how? Would their great leaders be involved or hide in safety? Hmmm. Interesting.
My classes are in public schools. In the U.S. any mention of a religious philosophy would be crazy. My home schooled groups are devout Christians. It wouldn't work there.
Anyway, good ideas, Eddie.

I am a chess club president at my high school, but lately the members have grown bored of chess, does anyone have any ideas on how to help keep things interesting for them? They are all amateur players so nothing to advanced.
