sunday school helps

hey all! My calling in our ward is teaching sunday school to the 16/17 year olds. Last week was my first time with my new class and while they'll be fun, they are very chatty and energetic. :) do any of you have good ideas of fun games, object lessons, etc? There are 10 kids that come so i've got a good size group. (especially since last year my class was only 2 kids!) I've got some ideas but they won't last an entire year! Thanks! And I got an email from one of the moms and apparently her daughter said I'm awesome, so I know at least one kid likes me!
