Mt. Pinatubo, Phillipines, 1991
What We Study
Linus has really been into volcanoes for the last couple of weeks, so we checked out a National Geographic movie about them from the library. It's a pretty great summary of the subject, with some outstanding footage and descriptions of various eruptions throughout history. In particular, there is good coverage of Mt. Pinatubo's eruption in 1991. Let me just say, when that thing blew, it blew. It sent a smoke column 12 miles into the air, deposited 2 cubic miles of debris into the atmosphere and surrounding area, and completely blew the summit off the mountain. I know there have been other eruptions since then, but as far as I know that was the last major eruption in the world, meaning that another is probably just around the corner.
Much of the movie talked about vulcanologists, which led to this discussion with Linus:
Him: "What are those guys doing?"
Me: "They're vulcanologists. They study volcanoes."
Him: "Why?"
Me: "So they can predict when volcanoes will erupt, to help save lives."
Him: "What does 'study' mean?"
It's a constant process of trying to extend the boundaries of his world, but also of doubling back and filling in the gaps that you've missed in your efforts to get to an explanation that you understand. Helping young kids understand the world is sort of like doing technical writing. You can't just say: "Connect everything and turn it on." You have to explain what goes where, define things as though the people who are reading the instructions have no idea what you are talking about.
Likewise, you can't just tell kids that the Earth orbits the sun. You have to tell them what "orbit" means, and once you do that, they ask why, and you end up discussing gravity and a dozen other things.
It's good. It can be a challenge, at times, but when you break things down to their basic elements, sometimes you can see things in a new way yourself. We both learn.
The concept of "study" seemed to catch his attention in some way that I couldn't quite pin down. I explained that studying things was a good way to learn about them. Some people study plants, others study history (which started a side discussion on history that I shortened for a later time), and others might study paintings. There was a ladybug in his room, and I told him there were people who spent almost their whole lives just studying ladybugs. He scrunched up his face and looked at the bug for a few seconds.
Well, maybe that one's not for him.
