An entire evening revolving around apples.
Possible Large Group Time lesson could be Adam and Eve (discuss disobedience and how and led to sin and what the consequences of sin were and are today); or Psalm 17:8, the apple of God's eye (Use several apples - one that looks perfect, one with a blemish on the outside and one with a gummy worm in it. Talk about sin, our blemishes, and what sin in our life can do and how it can spread). Give apples as awards/treats, possibly giving the winning team candied apples.
For game time you can bob for apples, have an apple toss, hang an apple from the ceiling and a blindfolded team member tries to bite it while others shout instructions, etc.
