Nuremburg Chronicles Empedocles

Anaxagoras and Empedocles, from the Nuremburg Chronicles

In my last post, I showed the statistics of what this blog has accomplished so far. I feel very good about where we’ve been, but now it’s time to describe where I plan on going this coming year.

Given that I am not teaching chemistry this school year, my work on the Elements Unearthed project has slowed down a bit as my attention has been diverted elsewhere by the astrobiology projects (the podcasts and CLOE animations) and other projects that I’ll describe next week. I anticipate teaching chemistry again next year, and I am in the process of writing up a series of grant proposals (all of which have to be done by Feb. 1) that, if successful, will provide funds for purchasing some iPad tablets and probeware that will allow us to do some environmental field research.

In the meantime, I have a large backlog of videos that I have taped of various mine tours and interviews I’ve done across the country. I need to edit these into final videos and report on them in detail on this site. In order to keep myself on track, I’ve created a schedule for when I’d like to do each video and the topics I’ll cover here as I work on them.

This January, 2012, I am going to start at the beginning and look at ancient chemistry and our knowledge of the elements in prehistoric and early historic times. Then in February, I will start to work on my Greek Matter Theories videos. I have previously created all the script and narration and have even set up the video files and begun the graphics and animations. It’s high time I finished these. I’ll start with an overview of the Greek Ideal in philosophy and science, then talk about Thales and the Miletian School, then Parmenides and Zeno and the Eleatics. In March, I will talk about Heraclitus and Empedocles and the atomic theory and Plato. In April, I’ll move on to Aristotle, Epicurus, and the debate on elements versus atoms, ending in the theology of St. Thomas Aquinus and how atomic theory came down through the Middle Ages.

In May and June I’ll discuss the practical side of chemistry, with a look at ancient crafts, including metalworking, glass making, and other medieval technologies, including a detailed look at Agricola’s De Re Metallica (which I have many photos of).

By July I should have the funding I need in place to start the field research. My plan is to partner with another school, perhaps Tintic High School or Wendover High School, to travel out to nearby mining sites and use the probeware and iPads to collect and record data on soil and water environmental conditions, such as the pH of soil and runoff water near old mine dumps. I’m especially interested in seeing if the EPA efforts to mitigate contaminated soil in and around Eureka, Utah have been successful. I’ve talked about those efforts in previous posts (especially here: https://elementsunearthed.com/2010/06/09/the-legacy-of-the-tintic-mining-district/ ), so I won’t talk about them again now. We would use GPS coordinates and GoogleEarth to set up a grid of sample sites both in and out of the recovered area. We would sample the surface and two feet below ground. It would require several trips and coordination with local students to gather the data, but it is a project that would fit very nicely with the research I’ve already done. If I can get enough money together, I would like to rent a portable X-Ray Fluorescence Spectrometer which can read element abundances nondestructively on the site.

In preparation for all this, I need to make one more trip to the Tintic district in June to photograph and videotape the mines in the southwest area, which were the first mines discovered, including the Sunbeam and Diamond mines. One of my great grandfathers, Sidney Tanner Fullmer, died as a result of injuries suffered in an accident while working in the Diamond mine, leaving my grandmother an orphan to be raised by her aunt and uncle. So this history has a particular interest to me.

One thing I plan on doing, if we can work out a partnership, is to set up an evening in Eureka at Tintic High School where townspeople can come in with photographs and tell their stories of mining and life in Eureka before and after the EPA efforts. We’ll scan the photos and videotape the recollections, then combine all that with the video I’ve already done of the Tintic Mining Museum and local area. Ultimately, my students will help me script and edit a three-part video on the Tintic District, perhaps even done well enough that we could market it to KUED, the PBS station in Salt Lake City.

The months July, August, and September will be dedicated to this effort and will result in the best documentation created so far on video of the history and present of the Tintic Mining District.

October will be dedicated to Zosimos of Panopolis and such Arabic alchemists as Jabir ibn Hayyan. November will begin a discussion of European alchemists, from Roger Bacon and Ramon Llull through the Middle Ages. I’ll draw on the many photos I’ve taken on alchemical texts at the Chemical Heritage Foundation. The history of alchemy will continue through December, 2012 and on into January, 2013. In February and March, 2013, we’ll discuss the emergence of modern chemistry through Boyle, Priestley, and Lavoisier through Dalton, Avogadro, Berzelius, and others.

In April through June of 2013 we will switch gears and talk about nucleogenesis and the origin of the elements, then the physicists and chemists that have helped us understand the structure of the atom and quantum mechanics. From there, I will probably begin to talk about individual elements and how they are mined and refined, with examples of the mining districts where they come from, such as the history of the Viburnum Trend in Missouri and the lead mines there, or the gold mines of Cripple Creek, Colorado. I really do have enough materials now to keep this blog going for at least two years. And I’ll be gathering more all the time. I will also dedicate occasional posts to my efforts as a chemistry teacher and to science education in general, including my experiences at conferences, etc.

Well, it is an ambitious schedule. I hope to do at least one post per week, probably on weekends. I hope to complete at least one video segment every two months or so. Next week, I’ll start us off with an overview of the history of chemistry.

Ramon Llull portrait

Portrait of Ramon Llull

As we have studied the history of chemistry for our recent unit in Honors Chemistry, I’ve had my students do a bit of research on what is known and supposed about various alchemists. For example, a student in each of my sections was assigned to research Ramon Llull, the Majorcan alchemist. We started by finding out what is known about the real person. He was born in Palma in 1232 AD, and was a courtier, poet, and womanizer at the court of King James of Aragon, then had a religious epiphany that converted him into a fervent missionary for Catholicism. After a nine-year hermitage and writing many religious tracts, he set off on a series of missionary journeys to North Africa. He was fluent in Arabic and was unusual for his time in that he believed in converting the Muslims through reasoned argument instead of Crusades and the sword. He wrote some of the first works in Catalan, his native language, and died after being stoned in Tunis.

I also had the students research what is attributed or credited to the person in tradition and later writings, such as Ramon Llull’s alchemical works and his having created the Philosopher’s Stone.

Each student also had to find an image of the person and include it, then take their short report and convert it to simple bullet points to summarize their findings. I’ve now taken those bullet points and turned them into a Keynote/Powerpoint slide show and added their images as well as photos I took last year at the Chemical Heritage Foundation as part of my fellowship sponsored by the Société de Chimie Industrielle (American Section). This is the first time, except for a few progress report blog posts, where I have started to use all the materials I assembled. I am attaching it here, and hope you enjoy going through it and using it in your own classes.

Sorcerers Apprentice

A Sorcerer’s Apprentice Masters the Transmutation of Copper into Gold

It was my privilege last summer to dig into the very books these alchemists wrote, and I’m still digesting what I discovered. One result has been my own creation of the White and Red Elixirs and the formation of the Stone itself; in fact, I demonstrated my alchemical prowess for my students by converting copper into silver and then into gold. Several of my students had achieved the inner transmutation sufficiently to successfully direct the Stone’s powers as well, as shown in the photo. (Of course, we really aren’t making gold. This is the old “Alchemists Dream” activity where copper pennies are coated with sodium zincate [using a combination of 6.0 M sodium hydroxide and zinc powder], then heated gently in a Bunsen burner flame to alloy the zinc with the copper to form brass, which looks like gold).

These student-created projects are part of my overall philosophy of science education and the main rational of this Elements Unearthed project: that students learn best when they are actively involved in sharing their knowledge with others. With modern tools for publishing on the Internet through blogs and PDF files, Powerpoints and videos, students now have an audience for their work that is much greater than simply their peers and teachers in class. Tomorrow is the unit test; we’ll see if my theory holds water then!
