The Elements Unearthed

The Five Elements

As I teach chemistry and astronomy again for the first time in several years, I’m having a lot of fun getting back into the physical sciences with all of the lab experiences I’d collected and developed over the years before I started teaching multimedia exclusively. I’ve also added a number of excellent activities that I picked up from my experiences with NASA and from various conferences and presentations. It’s also a lot of fun to start incorporating my expertise in media design and technology in ways I never could before, as well as the materials I collected at Chemical Heritage Foundation in 2009. For example, I just finished teaching a Keynote presentation on Greek matter theories that I put together myself using photos, drawings, illustrations, and 3D animations (mostly my own) and information collected at CHF. I have all the files stored on various hard drives that all hook into my Mac Powerbook (about four terabytes total). Some of the images I pulled off the Internet at school using our wireless router and Airport technology, and once the Keynote was finished, all I had to do was hook my laptop up to a projector and give the presentation (complete with animations and audio clips) using an infrared remote. Here’s the presentation, in Powerpoint format. If you want to use it, be my guest:

To me, all of this seems remarkable, even miraculous. And here I am writing about it on a Blog, publishing my experiences instantaneously where anyone in the world can read them, and even sharing the presentation itself. Yet I feel as if I’m only just scratching the surface of what these new technologies can do. That’s part of why I’ve been working on this Elements Unearthed project for the past several years; there are so many connections between science practitioners and students that can still be made and which I hope to develop, so many innovative methods of teaching that no one’s thought of yet. I’m a digital immigrant; my students are natives. I’m always playing catch up to what they’re already using daily.

So far this blog has been written entirely by me (David Black) since it debuted in Oct., 2008. Now that I’m teaching chemistry again I am turning over much of the posting to my students, who will be taking turns once per week adding information about the research project they are pursuing. They have chosen between an element (such as copper), a material (such as cement), a method of generating energy (such as solar power), or a time period from the history of chemistry (such as medieval European alchemy) and are compiling notes into an MS Word document with references.

With each post, they are to include about 500-800 words of writing in their own words culled from all of their research notes and include relevant images or diagrams. They are also producing a nicely laid out document such as a newsletter, poster, or brochure that will be converted to PDF format and linked to this blog for download. It may take a week or two for the first few student posts to contain these linked files, but they will come. My hope is that any chemistry teachers or students out there who are reading this blog will be able to download these linked files and use them in your own classrooms.

During second term, the students will be developing and practicing a hands-on demonstration that involves some property or aspect of their topic. We’ll present these demonstrations to the elementary classes at Walden (I’ve already met with the teachers to plan this out) and the students will also present them to each other for feedback. During third term, we’ll create a more extensive project from their topic: a detailed Powerpoint or Keynote presentation or a three-minute video or a computer game. They’ll present these in class again, then fourth term put all of this together for a back-to-school science night for the public and their parents and siblings. We’ll videotape these presentations and share them with you as well.

I’ve done all of these things before in various multimedia or chemistry classes, but this is the first time that technology and opportunity have combined to allow me to put it all together. I am still looking to build partnerships with local organizations (museums, mining associations, etc.) that will combine my students’ media skills with their content. I’ll still visit mining towns, take tours of museums, and continue to post about how technology can be used in the science classroom. I also plan on writing more grants and professional articles. I’ll continue to create longer format videos to go with the student short videos (the Tintic Mining District is up next after I make some changes to the beryllium videos).

This blog has certainly been successful in what I’ve intended it to be. Last month (September) was the best month so far with over 2700 visitors to the site. I’ve had over 23,500 visitors total, most of them this year. I would love to hear from any science teachers or students that have found this site useful.

I look forward to seeing what my students come up with as they post about their topics. I’m encouraging them to do more than just a list of properties, to dig deeper and talk about the unusual stories and histories of each element or material. And now, I am pleased to introduce my chemistry students’ blog posts . . . .
