Science Learning is Deepened with the Right Tools

   When I heard about a package of learning tools - hardware and software - that was being utilized by Lynn Prosen and Teri Cosentino, I had to take a look.  Lynn, our Lower School science coordinator and Teri, our Middle School 6/7 science teacher, did training through the Liberty Science Center to enable GSB to borrow some equipment.  Here's Lynn at the controls of the learning tools:
Lynn's at the laptop managing software that determines what is shown on the globe in the background.

     The science lessons taught through the set-up are all based on data gathered by NASA satellites.  These satellites have been recording information about our planet as well as other planets and celestial bodies for decades.  As the data accumulates, it's possible to begin to see patterns of change over time.
      Want to see how the levels of chlorophyll change on Earth over the course of the last several years?  How about changes in ice pack as seasons come and go?  Interested in changes in gas densities on Saturn?  Or magnetic changes on Mercury?  Given the accumulated data, the possibilities for inquiry are virtually limitless.  As Teri said to me, "I'd love to create a course solely based on analyzing the data sets."
       What makes the data come alive is the hardware.  The data is put through a software tool that allows it to be projected on to a sphere.  In the photo above, the "Earth" is actually a translucent ball (about the size of beach ball), sitting atop a projector. The specially designed projector acts as a podium stand for the ball and also, through a series of mirrors, is able to project images on to the sphere.  These images can then be set in motion, so the Earth, or any other planet, will spin.  Students see a reasonable replica of a planet, spinning on its axis, illustrating wind, temperature or electron-magnetic changes, to give some examples.
       Below, a few more shots of the globe as it projects images from our solar system. The globe has not changed; the software controlling the projection is creating the image of the Sun, the Earth and Jupiter.




    The class I observed was a group of Sue Hone's third graders.  Their analytical skills were sharpened by a series of directed questions based on what they were seeing.  They were at first intrigued and then quickly were quite engaged in the lesson.  Here's a few shots of the young scientists hard at work:



       Though I did not get a chance to see a Middle School class, I did speak with Teri after her lessons.  Teri went through a full week of training at the Liberty Science Center over the summer to be fully ready to utilize the software to the fullest.  Though Lynn's preparation was not quite as extensive, both emphasized that the software was quite full-featured and training was necessary to make the most of the data NASA provides.  That said, I was still interested enough to check out the the web site, NASA Earth Observations, that houses the satellites' earth data.  It's definitely worth some "exploration time."

       By the time you read this the equipment will be gone from campus, but Teri tells me she's already reserved it for two weeks in December and two weeks in March.  If you are interested, it would be worth your while to find a way to see a demonstration.

Thinking about Technology

I didn't grow up working in technology.  I was a history major in college and spent most of my educational career as a history teacher and a college counselor.  As I enter into my fourth year as a "technology person," I remain awestruck by the capabilities of modern digital technologies.  Touch screens, streaming video, wireless networks and the such have become so familiar as to be taken for granted…unless they are not operating properly.  But surrounded by and working in our digital world, I remain amazed at what I am seeing.

So I work each day in technology, helping to create a web site, set up a projector or assist a teacher with a technology driven lesson.  But I'm also keenly conscious of this professional world I now inhabit because I came to it later in life and can see it with the fresh eyes of a relative newcomer.  Perhaps I'm more easily wowed than someone who has worked in the field for decades because he or she has grown up with the engineering changes.

Take a recent article in the New York Times (9/9/12).  The article offered an exhaustive look at the present and future of commercial space travel. Incredibly, to me at least, the article was in the Travel section.  Space travel is here, albeit only for the ultra-wealthy. 

This article and the idea of space travel provoked an interesting lunch conversation.  Money aside, "Would you go or not?" elicited the full range of responses.  More interesting was a collective musing over the world we live in where so many live in want, and a few can pay upwards of $100 million for a one-time thrill ride.  But all at the table understood that this article represented yet another instance where a technological threshold had been crossed.  Much like personal computers, cellular phones, touch screens and voice recognition, every few years we embrace (or grudgingly acknowledge) yet another technological leap forward.

So many of these technological developments seem like magic.  Movies on demand brought to your 60" flat screen LCD 3-D TV via a satellite?  An internet-based music service that uses an algorithm to determine what songs you'd enjoy hearing based on an initial choice? The internet itself, with its billions of pages of content, creative outpourings from all over the globe, news, weather, video, etc.  E-books, with an ability to hold in your hand a small library's worth of books, and add to that library virtually instantly with a click or two.  Truly, it's amazing.

But there's a physicalness to this magic, a point thoroughly documented in Andrew Blum's TubesTubes is a book about the internet, but not in the usual abstract way.  It is about the physical, concrete internet, the set of optical fibers and routers and servers and switches and tubes that have created a world wide web.  It's also the story of how the internet was invented and yes, Al Gore gets his mention.  Long ago, in the early 1960's, computer scientists in the forefront of the field explored first creating computer networks and then linking networks together.  They were called internetworkers. We have inherited their vision.

As their work progressed, they needed physical places to link networks. And the networks needed physical places to house data.  In both instances, warehouse structures with enormous space were utilized for the requisite machinery.  And fiber, as well as existing phone lines, was needed to connect locations.  In short, an infrastructure was created and it continues to grow exponentially.  When today's internet is considered, its physical presence is never mentioned.  Yet over the last several decades, an infrastructure has been built that equals, in scope and importance, the national highway system of the 20th century and the railroad lines of the 19th century.
   
There are risks attendant to this change.  The risks can be as personal as cyber-bullying or as mundane as the knowledge that one has spent far too many hours playing video games or web surfing with little to show for it. James Steyer's book, Talking Back to Facebook, vividly points to many of these personal risks and reminds readers that youngsters are most vulnerable. 


The risks can occur at an entirely different scale as illustrated in Worm by Mark Bowden.  It's a story of our time in which cyber-security experts attempt to secure individual computers and networks from a particularly vicious global computer virus.  Here, one learns about how the underworld has seen technological change as an opportunity for profit. The book is a reminder that the computer networks we inhabit connect us in sometimes unexpected and dangerous ways.

And though it's unclear whether or not having your online data mined constitutes a risk or the end result of a commercial enterprise, personal data is being gathered at a furious rate from digital users.  This has become the true commercial backbone of the internet and it is frightening to many savvy users.  But phone owners, EasyPass subscribers and a great many other consumers in the digital world are ceding their privacy for the advantages of comfort and efficiency.

I've spoken to enough teachers over these few years to know that many feel a bit overwhelmed by the technological change they see.  That's not an admission of weakness or a characteristic of old age.  Rather, it represents an awareness.  If you're not feeling a little overwhelmed, you're not paying attention to the rate and quantity of change.  Unless you are a product editor for Wired Magazine, I would argue that it is impossible to fully keep up with the field.  But that's no reason to throw up your hands in defeat.  I really enjoy college basketball and pay attention as each season unfolds, but there are too many teams and players to stay on top of it all. I don't worry abut that.  I find parts of the whole I'm interested in and focus my attention there.  Find what works for you and utilize it wisely.  The technological world is remarkably interesting and ever-changing. It's worth exploring, but it's important to exercise caution as well.  So be curious, but be careful as well.
