The Great Pumpkin Investigation

This is one of the very first experiments I do with my kiddos every year.  And they love it.

Our goal is to see which pumpkin will decompose quicker the one carved like a Jack-O-Lantern or the one that is kept whole.  We begin our investigation by reading The Pumpkin Circle and Pumpkin Jack.

Then students make predictions about which one they think will decompose first. Then we carve one of the pumpkins.  When we are done I put both pumpkins in large glass jars (these are from Target).  I can't stand the smell of rotting pumpkins, yuck!

We make sure to record all of our observations in our investigation books.  Then we wait...
