Ants Be Gone!

Our hummingbird feeder was inundated with ants. While there are plenty of commercial options available for solving this problem, I wanted to try my hand at designing my own solution. In thinking about how a water trap should be designed, I came up with the following critical elements.

  1. A leak-free cup for the water (duh)
  2. An upper attachment point that prevents tipping of the cup
  3. A lower attachment point that is integrated into the monolithic design.

Here’s the result.

I’m not fast enough with the camera to take a picture of a hummingbird.

Students present at undergrad symposium

On April 28th, 2018, my first two undergraduate students at Brockport gave their first poster presentation at a professional meeting.

Shauna and Megan – ready to answer the tough questions.

The meeting was held at The College at Brockport this year.  There were 50 or so posters and about 100 attendees.  We also had a few oral presentations and the keynote speaker was Brockport alum Dr. Michael Nicholson of Precision BioSciences.

Megan and Shauna presented their first semester’s work on developing sensors and methods for OMIS: the Open Millifluidic Inquiry System.  Shauna is developing a method to perform alkalinity measurements in small volumes under dynamic flow conditions and Megan is working on a pH sensor based on anodically electrolyzed iridium oxide films.  They’ve made some great progress not only building confidence in their laboratory skills but also learning how to present their research (in addition to actually doing the work).  I’d consider that a good set of outcomes for their first semester in independent study (as Freshmen, no less).  Expect big things from these ladies.

P.S. Happy Star Wars Day.

Throwback Thursday – Brockport Chemistry take 2

Last week, I posted an early photo of a Chemistry lab from Brockport.  Not to be outdone, my wife Rozenn (historian of the Western Monroe Historical Society at the Morgan Manning House) found this picture in one of her books:The caption for the picture reads:

The [Brockport] Chemistry Laboratory: The 1899 yearbook describes the chemistry laboratory as “one of the best appointed in the state, having ample table room for 50 students at one time … The department has over $2,500 worth of physical apparatus, over 2,500 stereopticon slides and some 3,000 specimens.”

That $2,500 in instrumentation would be a bit over 70 thousand in today’s dollars, and I’m happy to say that our department has far more instrumentation than that.  The reference to thousands of specimens and stereopticon slides got me thinking about what was taught in Chemistry 118 years ago (hey that’s one year for every element on the periodic table).  A quick web search brought me to this article, (which is behind a paywall if you don’t have access to ACS journals) that reviews an historical Chemistry textbook from 1809.  It was written by Jane Marcet to “… provide women with a method of educating themselves in chemistry …” and uses a conversational style that is not seen in contemporary instructional materials.  This #ThrowbackThursday has me thinking about revisiting some teaching styles (to justify procrastinating on that pile of grading for one more day).
