A Beautiful Autumn Walk

We've been reading some fall books lately, like these:

and talking about all the changes that take place in nature in the fall, particularly in trees. We went for the most beautiful nature walk at a local arboretum - what better place to learn about trees and leaves?

We discussed simple and complex leaves, leaves with serrated edges, how leaves use CO2, water and energy from the sun to make food for the tree and how they give off oxygen, the breakdown of chlorophyll in the fall, deciduous vs. evergreen and all things leafy.

Speaking of leaves, does anyone know what these plants might be? They consisted of just one enormous leaf on top of a thick stalk. We found one fallen over that made an excellent umbrella.

Because there were bridges over running water, we played Pooh Sticks. If you have ever read (or listened to) the original Winnie the Pooh stories, you will understand that bridges over running water simply cannot be crossed without playing Pooh Sticks.

And some of us rolled down a large hill because, well, it was there. I guess that really needs no explanation. :)
