Pinecone Science: Fall Forest
Hot/Cold H2O

Luckily in Ontario, we have loads of both.
We set up our hot/cold water station and got down to experimenting.
Before we began, I asked what O thought would happen when the pinecones hit the water.
"Melt. Change colour."
Actually nothing happened when our pine cones entered the H2O.
Nothing. At. All.
Our pinecones were already opened to the max.
The temperatures have yet to dip, so Ontario pine cones are still sharing their seeds with the squirrels!
We realized we were doing the experiment in reverse; once the pine cones were placed in the dry container, they closed right up.
And back we went for round two!
