About mid-September I'm going to be teaching a Forest Unit. So I thought it would be fun to do a couple of experiments related to trees.
One of the first ones we'll do is called "Striped Celery". This is the experiment that shows the kids how plant stems and tree trunks carry water from the roots up to the leaves and flowers.
A cool extension of this experiment is to repeat it using stalks of celery without leaves and then comparing the capillary action between leafless and leafy celery. The kids will be able to see that the stalks with the leaves draw the water further up into the stem. Cool, huh? A clear indication of the importance of plant foliage!

I just love messing around with photoshop and this is what I came up with.
That's his and his fiancee's new puppy. Benji is so laid back he'll let Andy wrap him around his neck like a scarf.
