Treeline Habitat
We took a trip up to the top of the dome yesterday to study plants at treeline. But when you’re constructing meaning at a conceptual level, you need to establish a context. My group of town kids with little outdoors experience didn’t know what “treeline” was. So we started at the bottom and made a few stops along the way to the top. Our resident scientist took core samples from the spruce trees at the bottom, and then again at treeline.
I walked the kids toward the bottom of the valley on a trail I knew before we headed up the hill. The trail went down into a black spruce bog and we walked far enough down to where everyone got the idea that it was only going to get wetter. Then we stopped and looked around at what grew there. Not much tall stuff, stunted black spruce and a few sad birch trees, mostly. We stood on squishy muskeg that felt cold when we poked our fingers down into it.
Slightly higher and along the way back to the bus, we stopped in a mixed stand of birch and spruce growing on higher and drier ground, and we took a core sample from a healthy white spruce tree.
After climbing (in the bus) about 2500 feet, we reached treeline. We found some small black spruce, and we took a core sample from one of them. We can count the growth rings and compare their ages. The white spruce was about 30 feet tall.
The little black spruce up high wasn’t even half that tall. I’m curious to see what the age difference is. We’ll sand down the core sample to make it easier to count the rings.
We also took weather observations, looked around for animal sign, and made random notes, collecting things in baggies
There were berries, still, but only the cranberries were worth picking. If you like cranberries. We ate lunch at a huge rock outcrop near the top of the mountain in an alpine tundra meadow.
It was grand. Not rainy, and no snow yet.
The kids had a great time. They learned a lot about where we
live. And they figured out that life is tough for anything that wants to live that high on the hill. It was obvious to me that it was a hugely meaningful experience. One of the boys on the bus ride home said, “Mr. Noon, thanks for taking us on this trip.”
I’m glad we did it, too.

A great trip. I wish I could have brought my class along.

Doug: I was just sharing the story this past week of my own 6th grade teacher who took our class on a half-day field trip hiking just outside our town. That day made lasting memories for me. Your students are fortunate to have you as their teacher. Learning experiences like the one you’ve described develop lasting background knowledge, which we certainly need in greater supply in schools.

Great blog, Doug.
Yes, context really matters.
When I took up whitewater paddling ten years ago, I had to learn how to “read the water.” That made absolutely no sense to me at the time. C’mon, let’s just get in this boat and go!
My teachers helped me see the patterns I needed to know to get down the river. Reading helped me see how to move with, not against, the water.
From helplessly going in circles (literally!), I could move up and downstream, ferry back and forth, and even come to a full stop without falling out of my boat (most of the time).

I’m teaching science like I teach reading - reading the country, reading the physical world - so the comparison to reading a river is a good one. We need to have the big picture first in order for the details to have meaning because we need some way to organize them.
After we learn to recognize patterns in nature, we don’t see it the way we did before. Our perceptions are more focused, and we make finer distinctions. The plant biologist we’re working with told me that before he began his studies, all grass was the same to him. Now, he can’t look at the ground without seeing different kinds of grasses.
