There are those times when you get done early and have 10 minutes to kill before the next activity.  All you'll need to do is raid the scrap paper box and hand a pair sciossors to each kid.  Three cuts, five folds and you can make these cool helicopters in about 2 minutes (add 20 minutes if you teach kindergarten or first grade).  Not pickin' on anybody, i'm just sayin'…

This is the second activity in our "Build Your Own Model" category.  It is a very cool, very fun, end of year activity for the kids.  They will make a water rocket launcher that shoots pop bottles into the air.  There is a lot of interest, a lot of water and plenty of screaming, applause, and cheering.  You can make an entire week meaningful and memorable if you work it right.
