Gleanings of the Week Ending December 28, 2013

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.

Short Cycle Efficacy Trials Key to Personalized Learning - How can the myriad of education applications and blended learning models be evaluated?  This article describes some attempts. Hopefully we finally will achieve the focus of efficacy for the individual learner rather than the technology or educational administration.

4 Frighteningly Ambitious Education Experiments for 2014 - There are lots of experiments that I’ve been reading about lately (prompted by some recent Coursera courses). These four caught my attention because they emphasize that many boundaries we one assumed have been softened or even breached by technology. So now - we have some alternatives that have never been available before. All the more reason to figure out how to do ‘short cycle efficacy trials’ (see previous gleaning).

Frogcicle - I’d heard about some frogs being able to survive freezing…this is a video that shows that happening.

A Dingo Ate Australia - The article portrays the dingo, Australia’s only native dog species, from multiple perspectives.

Petrified Life - Time lapse video of the American Southwest…well worth the 5.5 minutes to watch.

The Most Incredible Historical Discoveries of 2013 - It’s the time of year that we get a lot of ‘best of’ lists. It does seem that 2013 had quite a few rather surprising historical discoveries. History is not as well defined as we sometimes assume!

Greenland Ice Stores Liquid Water Year-Round - Water evidently stays liquid in the space around the ice particles in an aquifer that covers 27,000 square miles. A team drilling core samples in southeast Greenland was surprised when they came up with liquid water (from 33 feet in one hole and 82 feet in another). The air temperature at the time was minus 4 degrees Fahrenheit. Another article on the same topic is here.

The 100 essential websites - How many of these do you know about already? I always take a browse through lists like this - and sometimes discover a something worthwhile!

Waiting in the Wings - Mining collections (butterflies, plants and birds) to determine changes over the 19th and 20th century as individual species - and in relationship with other species. Not everything in the food web changes at the same rate.

These are the most beautiful libraries we've ever seen - I am reading more electronically these days but there is still something very appealing about rooms full of books. 

Butterflies on the (Blooming) Joe-Pye Weed

 

 

 

The Joe-Pye Weed at the Robinson Nature Center is blooming and full of insects right now here in Maryland. The most noticeable insects are the butterflies: Easter Tiger Swallowtail and Spicebush Swallowtail.

There are so many of them it is quite easy to get some excellent photographs of the insects!

Ten Days of Little Celebrations - July 2013

Back in August 2012, I posted about finding something to celebrate each day. It’s an easy thing for me to do and the habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations;’ here are the top 10.

Starting the day outdoors. For years and years I was always heading off to work or errands as soon as I was able in the morning. It is such a luxury to be able to enjoy the outdoors on July mornings when the heat of the day is yet to become overwhelming and the birds are at their most energetic. What a great way to start my days.

Watermelon. I still think the large watermelons with seeds from many years ago had a better flavor than the smaller, seedless varieties in the stores today - but, even these watermelons are a hallmark of summer for me.

Cheesecake sampler. Don’t they always look tempting in the store? Always being on a diet means that I had not succumbed to the purchase until I had a dinner party with enough people to eat most of the pieces in a single sitting. So - I celebrated when I finally found a cheesecake sampler (at the third store I checked) and thoroughly enjoyed the one piece that I permitted myself.

Butterflies on the blazing stars. Flowers and butterflies - easy images to celebrate. See my earlier post here.

Credit for the electric bill. One of the days the exterior of our house was being painted was also an electricity conservation day (our electric utility gives us a credit based on the amount we reduce from a baseline day of similar temperature). The windows were open anyway for the painters - so we turned off the air conditioner and ate picnics (i.e. no cooking). We got at $46 credit! Hurray!

Cardinal flower. Plants are one of my favorite gifts (to give or receive). I celebrated receiving a cardinal flower and enjoy its blooming stalks (increasing rapidly in its big pot) every day. See my earlier post here.

Exterior house painting complete. The house looks wonderfully refreshed….I celebrated that the crew finished in spite of a significant rain delay! See my earlier posts here and here.

Into ‘normal’ weight range. Shouldn’t this be a goal for everyone? I am celebrating getting into the range…and closer to the ultimate goal (another 10 pounds to go).

A quiet day without internet or cable. A storm came through and the service people don’t work on the weekend…so we were without connectivity for almost 48 hours. I found that there was a new quietness about the house to savor…although I also celebrated when the connection was restored too.

Pecans in buttermilk pancakes. I celebrate the goodness the dusting of pecans adds plus the memory of learning to sprinkle the nuts onto the batter as it cooks from my mother.

What have you celebrated today?

Cardinal Flower in a Big Pot

I received a cardinal flower as a gift late last week. I decided almost immediately to put it in a pot since it likes to be kept very wet - wetter than any area stays in my yard. The plant was already beginning to droop in the small pot from the nursery because the water drained away so quickly.

I bought a large pot for the deck that I could keep soggy even in the hottest weather. The shells from South Carolina went into the bottom. Next - every partial bag of potting soil, vermiculite, and sphagnum moss in the garage went into the pot (what joy to finally be using up all cobwebby bags!). The plant was positioned in the pot - and watered.

I’m looking forward to the plant beginning to bloom….anticipating hummingbirds and butterflies.

Blazing Stars as Insect Magnets

My bulb project from April 2012 is quite lush this summer. The Blazing Stars are almost always full of bees, butterflies, and hummingbird moths. There are more plants this year and the heights seem more varied. And - best of all - the deer do not seem to find them palatable at all! The slide show below captures my favorite visitors to the Blazing Stars for the past month or so.

Brookside Gardens ‘Wings of Fancy’

One of the Brookside Gardens conservatories is currently dedicated to the annual live butterfly exhibit - ‘Wings of Fancy.’ It was very warm on the day we were there. The butterflies were very active but I didn’t linger as long as in previous years.

Butterflies are calming and invigorating at the same time. They are calming because they are so beautiful in their coloring and shape and the way they move. A better name for them would be ‘flutterbies’ to describe their motion. They are invigorating because they are in motion most of the time on warm days. Many of them open and close their wings even while they rest.

But they are short-lived creatures. Their wings become battered in a short while even in the relative protection of the conservatory. We know their life cycle: egg to caterpillar to chrysalis to butterfly - with the near magical metamorphosis taking place in the chrysalis phase. Enjoy the slide show from my walk through the 2013 Brookside Wings of Fancy!
