SCAVENGER HUNT : I divide the class into teams of 4-6.  Whatever will give me six teams.  Then I hand out the list of items to find.  They must leave the list face down until all lists are handed out(note that each list is slightly different)  Items that are common enough and small enough must be physically collected.  Large items or items that there may only be one of will have a series of tags connected to them.  Students will take one tear off tag(taking all the tags will get your team disqualified).  When all items are retrieved they must be verified against the list by the teacher. 

I play this in middle school and I give candy treats . I have a bag of Chocolate kisses and some fruit chews (obviously each individually wrapped)
WINNERS: each member of the team gets 3
SECOND PLACE: each member gets 2
OTHERS: If the team finished, each member gets one!

You could give bonus points, one free quiz you don't have to take etc.

HERE ARE MY SCAVENGER CHARTS :
(To make  tearaway tag type words for items 6 times. Print and cut each grouping as a square with a margin on one side for taping.  Cut almost all the way through between each word for easy tearing)
