Nanotechnology Institute, Day 3


Geobacter Setup in Morrill at UMass Amherst

We started day 3 of the Nanotechnology Institute by touring labs in Hasbrouck in which research involving nanostrucutres happens.  The process of lithography was explained, which I have experience in the Class-100 clean room at the BU Biophotonics Building.  One of the highlights of touring the laboratories was seeing the Atomic Force Microscope in action, imaging a series on nanotubes.IMG_0264

The second tour we went on was in Morrill IV, and dealt with Geobacter in Derek Lovley’s laboratory.  Dr. Nikhil Malvankar presented his research in regards to Geobacter and it’s practical uses in our society.  One of the most interesting facets of this research is its potential uses in portable outhouses.  It could potentially break down the waste, removing the smell, while creating power that could power a fan, sensors for how full the outhouse is, and light for use during the night.  Furthermore, a sensor system could relay this information to the central hub of the waste company.  You can study these bacteria in your classroom, using the Keegotech Mudwatt system.IMG_0266

We then learned about magnetic memory storage and created a binary coded alphabet exploring secret “coded” messages.  This would be potentially useful in a physics classroom or intro computer class.

UMass has created a virtual clean room tour, which gives you an idea of what a clean room is like.  Clean rooms are important when working on the nanoscale, because even the slightest bit of contamination can ruin your sample.

We then explored self assembly of items in a station like system.  We went station to station, using wood shapes.  There was particularly awesome set up with magnets floating in bottle caps in a small dish.  When you put in like magnets, they repelled each other away to form an equidistant design.  When you put in different magnets, they self-assembled into a shape.  This activity will be a great way to demonstrate bonds in my classroom.

Mort Sternheim went on to talk about potential Nanotechnology Careers, and we met in subject groups and talked about what we envisioned our student’s preferences towards STEM careers.

STEM Digital Day 1


The first day of STEM Digital was a great experience.  Mort Sternheim greeted us, and there was a lovely breakfast provided for us during registration.

We started the day with John Pickle explaining how to use the ADI software to analyze a leaf, using basic measurement and area techniques.  I became excited, because I believe this software will be very useful in measuring the pH in a few laboratories that I run.

Jennifer Wellborn, of Amherst Middle School, explained how she uses the software in her classroom with a few assignments, including with diffusion and crayfish.  We set up these experiments in the lab, to let them run the course of the week.  I am interested to see whether the crayfish turns color based on its environment.

We went on to talk about albedo and climate change.  Our assignment was to take a picture of white printer paper and measure the reflected light, comparing it with a darker medium (grass).

Steve Schneider presented how to measure angles with the ADI software, guiding us through Earth and Space Science.  We tried to measure angles of people’s faces, and see the basis of facial recognition software.

Finally, Dave Reckhow talked about water quality and water treatment, focusing on natural organic matter in water.  We set up leaf leaching experiments, to focus on analysis later in the week.

Looking forward to Day 2 tomorrow!
