Going to Class in December

The community college in the neighboring county hosted a Freshwater Benthic Macroinvertebrate Workshop on Monday and Tuesday this week. It was two full days of day of taking small critters (preserved in alcohol) out of vials, putting them in a small Petri dish, and looking at them under a microscope. There were two lab rooms full of student – most teachers or Master Naturalists or environment monitoring related non-profits or government organizations. I’d signed up as soon as I heard about it….a great opportunity to see a lot of specimens and improve my ability to identify them for upcoming field trips with students in the spring.

It’s been a long time since I was in a lab like this – since the 70s!  I liked that there were actual chairs with backs rather than stools. I can remember classes held in labs and being very uncomfortable both from the hardness of the seat and not being able to lean back at all. We also had a microscope for every student; when I was in school we always had to share.

Some of the things I saw, I won’t see on the field trips because we don’t have enough magnification: oval shaped gills (easily detached when preserved) or comb-like spines (that look like false eyelashes) that distinguish certain families of mayflies (Ephemeroptera).

I learned about Macroinvertbrates.org and am looking forward to seeing its continued development. The family-level key we used in class is also online. Generally, we only classify to order on the field trips.

In the foyer of the building – where we registered and a table was filled with morning caffeine urns...and donuts that called all of us to jettison our diets…there was a display case of bones, which dovetailed nicely with the osteoarcheology class I just finished on Coursera. There were pathologies (like arthritis) and young bones (with the defined areas near the ends where growth was occurring).

I enjoyed the course tremendously and have signed up for another anatomy related course from the same university. I seem to be focused on biology related topics this December!

Gleanings of the Week Ending November 19, 2016

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The past, present and future of the food we eat – Short…interesting…dystopian future from my perspective and one that a good number of people are trending counter to.

Open Parks Network – A collaboration between Clemson University and the National Park Service to digitize materials from our national parks, historic areas and other protected areas.

Learning in the Age of Digital Distraction – Thought provoking. Has our ancient food-foraging survival instinct evolved into an info-foraging obsession? An interview with neurologist  and professor at the University of California, San Francisco that is one of the authors of a new book: The Distracted Mind: Ancient Brains in a High Tech World.

High hospital profits hurt medicine, expert argues – Yet another reason our medical costs are spiraling upward…and our healthcare not improving.

10 Weird Way You Could Be Spreading Invasive Species – The bolded text says ‘running shoes’ but the picture shows hiking boots…any outdoor gear needs to be cleaned after each outing…no weed seed hitch hiking allowed.

Interactive Periodic Table Reveals Exactly How We Use All Those Elements – A little chemistry lesson…at the elemental level!

Vibrant Maps Beautifully Visualize the Feather-like Flow of Rivers Across the World – Educational…and eye candy. Look how big the Mississippi river basin is!

How land use change affects water quality, aquatic life – Evidently static water levels in small lakes and impoundments…a goal of current approaches to dealing with excess water…fish production declines over time.

The Human Virome – Infographic. There are viruses almost everywhere in our body! Most of the time they help – just like the bacteria that we carry with us – but the can turn pathogenic.

One in six women diagnosed with breast cancer has a symptom other than a lump – That 17% - and some of these ‘symptoms’ were new to me. Why aren’t they publicized more?

Learning Log – May 2016

Most of the learning I logged in May was experiential or in conversations with other people. I went to a lecture on wildflowers – the closest I came to a class. The speaker included a segment on buzz pollination, reinforcing what I already knew about it from my son-in-law about the topic. He also pointed out that the jack-in-the-pulpit flowers look the same from the outside but the male and female flowers are quite different inside – but one has to cut away the outer part of the flower to see the structures. Not something I would do!

One area of experiential learning in May was picking strawberries. Years ago when I picked strawberries, I did so on my knees so I was pleasantly surprised that the mounds of my CSA’s strawberry patch made it easier to just bend over to gather the fruit. I’m still enjoying the strawberries I picked.

The other big experience of the month was using the scanner – primarily for old slides, pictures and Zentangle tiles. I learned to use a can of compressed air to clean the dust off periodically and how to scan multiple items at a time (into separate images). I also raised the scanner on a stand so that I didn’t have to bend over slightly each time I loaded it.

There were a lot of factoids I picked up in conversations with other naturalists before field trip hikes:

• Carolina wrens build multiple nests and then the female chooses one (from a birder),
• Earthworms come to the surface during rains not because they are drowning but because they are migrating (from another naturalist that had been reading about it),
• How the ‘points’ of antlers are counted (from a chaperone of a hiking group),
• Inexpensive wire mesh kitchen strainers work great to capture macro-invertebrates in rivers and streams (from a leader of a field trip to the Patapsco River).

Learning Log - April 2016

The majority of learning in April was experiential rather than formal course work although it seems that I always have at least one course in progress or scheduled!

I learned about mealworm cookies and Fresh Paper (for keeping strawberries fresh longer) while during my volunteer gig at my county’s STEM Fair and

Realized that I was glad cooking for 12 people was not the norm for me (it is quite a bit more work that cooking for 2-4) and

Was pleased that I didn’t panic when an opossum carcass turned up beside the stream where 7^th graders were going to appear to search for macro invertebrates in a few minutes (no shovels were available so we pushed the stinking mess into a bucket and dumped it into some nearby brambles).

I did take a macro photography class via Creative Live: The Art of Seeing: Macro Techniques for Flowers and Plants with Frans Lanting. I wanted the course on the day it was broadcast (and thus ‘free’) and then have been experimenting with selective focus since then. One of my first attempts is the picture below. It is fun to ‘fool’ the autofocus on my Point and spShoot camera (a Canon Powershot SX710 HS) into creating blurs in the foreground and background.

I also finished the second unit of the Soul Beliefs course available via Coursera from Daniel Ogilvie and Leonard Hamilton at Rutgers. I’ll do the third and last unit after the spring field trip season is done – maybe start in mid-June.

Learning Log – February 2016

There are so many ways that we learn new things. Since I started logging something new I learn every day – I am more conscious of how varied what I’m learning and the way I am learning it really is.

Observation is a way to learn new things. Birds were very active in February in our area and two ‘new to me’ observations were mourning doves making and geese climbing from open water up onto ice!

Experience. Several items on my learning log fit this category: 1) I started experimenting with not wearing my glasses and discovered that I rarely need them when I am working at my computer…and the neck/shoulder discomfort I had started to feel sometimes later in the day has completely disappeared. 2) Another learning experience this month was having a thyroid nodule biopsy; it was not bad but I really am not keen to have another one. 3) I learned to use a laminator (to make a tree identification guide more durable). It isn’t a big thing but was ‘new to me.’

Books. I started looked at the Hathi Trust collection of online books; there are so many items there is it overwhelming; botanical prints are my first ‘theme’ for browsing. On the physical book side, I read several books about Wild Life Refuges and have already started applying what I read to vacation planning; we’re going to visit the 4 National Wildlife Refuges on the Eastern Shore (of Maryland and Virginia) in March: Eastern Neck, Blackwater, Prime Hook and Chincoteague. In the Internet Archive arena my theme for browsing in February was ‘wallpaper’ with particular focus on wallpaper catalogs from the year I was born!

Udemy’s Photography Masterclass: Your Complete Guide to Photography). I finished as much of the class as I was interested in. I learned a few things but realized that I am spoiled by the quality of the courses I’ve taken on Coursera and Creative Live. The 4 Udemy courses I have taken are just not up to the same standard in terms of production or content.

Coursera’s Soul Beliefs (Unit 1). I finished the 11 ‘weeks’ of lectures for this portion of the course and will start on the Unit 2 lectures in March.

Coming up in March – there are already some other types of learning coming up: travel and ‘live’ classes.

Learning Log – January 2016

December was full of learning opportunities - surprising with no Coursera classes!

Udemy. I discovered a new-to-me source of free or inexpensive short courses. The first one was referenced in the Ancient Egypt course I’d completed via Coursera in November. The courses I finished in December were:

Blue: a symposium exploring aspects of life in Ancient Egypt

Napoleon in Egypt

I have already started two more in January:

Unearthing the Trojan War: The Life of Heinrich Schliemann

Photography Masterclass: Your complete Guide to Photography (I got it when it was on sale for $10)

The Udemy courses tend to be chart sets with a lecturer…not as many references or extended reading that usually accompanies the Coursera course. Still – I enjoyed the topics and will explore more of the courses they offer.

Travel to Hawaii. The biggest source of learning experience in December was traveling to Hawaii. I had never been to anyplace like it and the length/complexity of the travel was more too. There were all kinds of tangential topics too – like learning about Dengue Fever (they were having an outbreak while we were there).

Looking forward into January – I am set for more courses because there is not so much going on otherwise. Along with the two Udemy couses, I’m starting one from Coursera as well: Soul Beliefs: Causes and Consequences – Historical Foundations.
