Via
patrissimo comes a variety of fun and useful science-y links.
First, an article on
science, football, and danger, making an interesting point on why we have fewer people entering the sciences in college and a much lower level than previously of general science knowledge among non-scientists.
Second,
an absolutely amazing periodic table. The online version is interactive; he also sells print versions, which are not quite as informative, but much better for posting on walls.
Third, the text you get when your mouse hovers over "Tin" on the above periodic table is, "The classic tin soldier was sometimes made of pure tin, but more often tin-lead or lead-antimony alloys, or, shudder, just plastic. I cast this one out of 99.99% pure tin in an antique mold meant for kids to use." The picture representing tin is of a tin soldier mounted on horseback; if you click on the "Tin" square, it will take you to
many more tin-related pictures, including one of the mold he used to cast the tin soldier. My first thought on reading that the antique mold had been
meant for kids to use -- "They let
kids cast things out of
metal?!?!!" -- nicely illustrates his point in the article in my first link. We've sapped home and classroom science of all its fun and danger, making it safe, tame, and -- let's admit it --
boring. He attributes this to an unspoken national agreement that football is more important than science, and certainly, being a geek at a school with a good football team will give you a very convincing proof of this. But I'm inclined to think that there's also a contribution from our national/societal move from farm to city, and from physical work to office work. We no longer view children as being capable of real work; we no longer view work as involving physical risk. Combine these, and we see no reason for our children to take physical risks with themselves -- except for the fact that they have to run off all their energy somehow, and so we sign them up for sports, accepting the fact that the running off of energy will inherently be physical, and thus involve physical risk. But science? That's an intellectual endeavor; we don't expect our children to do anything actually useful in that realm, they are there strictly to learn, and their learning should be as safe as our paper-pushing jobs in our offices. We compartmentalize our lives, remove physical risk (and activity) from as many compartments as possible, and wonder why so many kids suddenly need Ritalin and nobody likes science any more.
Laura Ingalls Wilder's birthplace features a log cabin with a loft above the bedroom and pantry, which was used for food storage and as a sleeping place for Mary and Laura. When we visited last fall, we noticed that this loft had
no railing. Were it my house, I would want a railing there; I think there's a balance-point to be sought in issues of safety. But we've swung too far the other way, and even knowing that, it's hard to figure out even vaguely where the balance point should be. My knee-jerk reactions, it seems, are still more educated by my culture than I'd realized. I'm thinking now that some soldier molds and some tin sound like a great birthday present for T -- although I'm guessing that it was probably originally used by older children than he is, and that he should still have adult supervision and help in using it for a few years yet. That's another societal change -- children used to play with actual physical toys at older ages, and now we expect them to transition to electronic-only play by the time they're preteens. Silly us!
Also, sudden random epiphany: In spite of my half-chemistry background from college, I have a
very poor chemical intuition. A large portion of this, I know, is due to my own failure to attend enough chemistry lectures as a freshman. But I wonder how much of it was also due to never having access to chemicals outside of controlled "experiments" that were really more about teaching us to be precise and keep good lab notebooks, both of which were really really hard skills for me, to the point that they completely distracted me from the fact that there was
chemistry happening
on my lab bench!!! And I see the need for a balance point there, too -- the lab skills are important, and you do learn more if you have a record of what you've done to look over, and there are effects you won't notice at all without attention to detail. But I wonder what would have happened if they'd given us a bunch of random chemicals with labels, a fume hood, some basic equipment, and perhaps a list on each label of which things you should
NOT mix that chemical with (so as to avoid excessive levels of danger). Wow. OK, now I know what the benefit of the home chemistry kit was to children growing up fifty years ago, and I want to do exactly this with my kids at some point. The dream house now needs to incorporate a fume hood or two somewhere.... Basement, or attic? Probably not a good mix with the commercial kitchen to permit/encourage enterpreneurial ventures by resourceful children, that'd probably give the health inspector heart failure.... *grin*
And how difficult is it to buy a good supply of basic chemicals, as a random not-a-professional-chemist? Have we safety-fied ourselves out of this opportunity, as well? I will have to do some research.
Wow, that turned into more verbosity than I was planning on.
