Weekend in State College - Saturday

We made a last-minute decision to trek to State College PA to visit my daughter weekend before last. I had gotten a new camera the day before, so I experimented with it during the trip. The new camera is a Canon PowerShot SX60 HS and is billed as a ‘bridge’ camera in that it has a lot of features of my previous point-and-shot cameras but some added features too: optics that can accept added filters, some dials that make it easier to do some functions manually, and viewfinder + screen rather than just the screen. The optics zoom to 65x rather than 40x of my older point and shot. Enough the same that I knew I could use it immediately and give myself time to get comfortable with the new features.

We got to State College just before lunch time…decided to go out to Mexican food for lunch then walked around the campus. I started taking some architectural pictures.

When we were in my daughter’s office I took close-up pictures of the plants in the window (I think she must have selected them to remind her of Arizona).

There was a graduation ceremony that had just ended, and we saw students in robes and their parents walking around campus. I took pictures of Old Main from several angles.

Next I utilized the 65x zoom for some botanical photography.

We had walked around long enough to stop at the Creamery for out afternoon treat.  I got bittersweet mint ice cream in a cup. Yum (and not as messy as a cone on a hot afternoon)!

Belmont Hikes with Summer Campers V

The theme for last week’s summer campers at Howard County Conservancy’s Belmont location was STEM (Science – Technology – Engineering – Math). I decided to a pick some STEM related activities that were more like field work than actual hikes.

As usual there were two groups of about 15 each. The first group was the younger one; some of that group were just getting ready for kindergarten. I started out by handing a ruler to each camper.

We started by using the rulers to measure samples I’d brought in a bin (a stick and tulip poplar seedling were popular) and parts of the nearby barn. We did quick tutorials for campers that had not used a ruler before. One student measured one of the tiles – discovering that it was the same across and up/down (i.e. a square). Six campers collaborated to measure the lentil over a low window of the barn (5 feet 4 inches)! Most of the time we tried to measure in centimeters although we used both sides of the ruler.

I started a log of everything we measured on a pad of paper and clipboard.

We measured most of what we encountered on our hike including flowers, several feathers, grass, pine needles and cones, a fake rock (used to cover equipment), holly leaves and berries, a stump and and some very colorful mushrooms.

The second group campers were a little older – up to 12 years old. First, we talked about examples of science new sources (like Science Daily). I used an article about the discovery of moths roosting in hollow trees in Florida as an example. Then I showed them the information about the moth in the Maryland Biodiversity Project site…the way I knew the moth lived in Maryland as well as Florida. And we all knew there was a hollow tree nearby.

I had two small flashlights and we started out.

We didn’t find any moths but there were a lot of spider webs in the hollow tree. There was something there that kept the spiders well fed! We found a dead cicada nearby in the grass and examined it closely before we started out next activity.

The second activity with the group was to determine the height of a tree using a piece of paper and a tape measure. The technique worked but after using it for 2 trees we decided a 25 feet long tape measure for measuring trees over 125 feet tall was too painful (we measured a tulip poplar and white pine)…and it was too hot for more field work. We headed back to the air conditioning and lunch.

It was the last day of summer camp at Belmont. These STEM themed hikes were a good finale for us all. Everyone is getting ready for school to start…and the training sessions for field trip volunteers start too.

Composting at Home – June 2018

I got a free composting bin when I volunteered with the Fishmobile; the Fishmobile was part of a larger event at a local nature center that included a composting demo. The county gives bins away as part of the demo (GEOBIN Composting System) to encourage backyard composting by residents. A Master Gardener talked about what was required to successfully compost (mixing ‘browns’ and ‘greens’ – mixing) and I felt confident enough to give it a try. The bin was packaged rolled up in a cardboard box although the Mater Gardener recommended that stakes be used to provide some structure to the bin; I remembered that I had some at home…so no barrier. The hardest part of putting it together was the tightness of the roll; the material wanted to stay rolled! It might have been easier for two people but I managed on my own. The plastic has slots and the kit came with plastic keys to fit into the slots and turn to lock the two ends together. I made it a little smaller than the maximum size. I put it under the maple tree in our back yard….positioned to the hose from the house can reach it in case it needs to be moistened during a dry period.

I had two longer metal stakes and a flag pole that had broken into two pieces to use as stakes. There were dried leaves from last fall that were already on the ground and I simply left them for the first layer of material in the bin (the area is so shady that no grass grows under the tree so I started leaving the leaves to provide some protection to the soil). Then I added some veggie and fruit scraps from the kitchen, shredded paper and cardboard. Later I added some soil from a pot that had broken.

The bin looks very large right now. It will be a challenge to keep the greens (veggie and fruit scraps, grass clippings, bush clippings) and browns (paper, fall leaves, small twigs) balanced. I might feel the need to get a shredder for the yard waste since smaller materials will decay more quickly. I’m going to get through the rest of this year without one…just to see how the well the minimalist approach to composting will work.

Howard County Composting Facility

I attended a public tour of the composting facility in the county where I life yesterday morning. There is an expansion of the facility being built now but the pilot program has been going on for several years – lots of ‘lessons learned’ being applied to the expansion that will allow more of the county – hopefully the area where I live – to have curbside compost pickup.

The part of the facility that is currently in operation starts with piles of compostables collected from homes and some farm waste (like horse manure).

View fullsize

View fullsize

After being chopped up, it is made into piles. The material is processed for about 45 days in the piles – moved around with bulldozers to get air to all the material so that the decomposers can work. The temperatures in the piles are high enough to kill seeds which is important to the users of compost as a soil enhancer.

The piles are made over two pipes that pull air from through the pile and then

Through wood chips and finished compost (the large pipe in the foreground has pipes that push air under the wood chips/finished compost on the other side) – an effective strategy to reduce odors. The only period when odors come through that filter – so far – has been after Christmas when the discarded trees are in the piles; the pine smell is not one that people are likely to complain about so kudos to the design!

While we were there, there was a pile that was ready to be moved to the area where the compost cures; the work was done with a bulldozer…making multiple trips.

The piles are covered with tarps during rains; the compost does need water, but the amount must be controlled. Run off from the piles and the area around them is controlled.

The new facility under construction will have bunkers rather than piles which will increase the capacity per area over the design in use now. The design capacity must be sufficient to handle the large volume of leaves in the fall. In my case – I wouldn’t send most of my leaves to the compost facility since I have forest behind my house that has absorbed the leaves from my yard quite well. If my area is one of the lucky ones to be included in the expanded service, I’ll decide if sending the front yard leaves to composting is easier than raking them to the forest!

Packing for Texas

I’m in Texas! I bought my ticket less than 48 hours before flying…so this was not a planned trip and I realized as I packed several differences from my usual trek to Texas. First, I don’t know how long I will need to stay so I decided almost immediately to check a bag rather than doing it all in a roll-aboard and a tote bag.

Second, I checked of the weather and realized that it is going to be a lot hotter than I’m used to (I’m remembering why I don’t like to go to Texas during the summer!); on the plus side, lighter weight clothes take less room in the suitcase. Third, since I will be staying for an indefinite time period, taking my regular sized toiletries rather than travel size makes sense (another reason to check the suitcase too).

Some things are the same as my usual travel…taking peppermints for the travel days,

Having the electronics (iPad and laptop) where I can get them out easily when I go through security….and an almost empty quart sized Ziploc – mostly hand sanitizer,

And a zipper case to contain the charging cables – phone, iPad, Fitbit, toothbrush, laptop.

I did not pack the kitchen sink….just all the comforts of home!

Social pursuits linked with increased life satisfaction -- ScienceDaily – This result seemed intuitive to me. As we get older and don’t have the level of social contacts we had during our career years, choosing activities that provide social interaction have to be done more consciously.

The State(s) Of Distributed Solar -- 2017 Update | CleanTechnica – Hopefully more states (utilities within the states) will jump on the bandwagon. There is quite an uptick since 2015 so the trend is in the right direction.

14 eBooks about Niagara Falls

In May, I found lots of books about Niagara Falls on Internet Archive and I’m featuring 14 of them in this post. They are free – easily viewed online with the lines I’ve provided. The books are from a Canadian collection of books (Brock University) and range from 1843 to 1922. There were three from the 1840s – showing that it was a tourist destination early on. (1843, 1845, 1846)

There were already boats going to the base of the fall by the 1850s. (1852)

A book from 1860 provided a panoramic view of the Niagara River (with the falls at the top).

There were trains to be place by the 1880s (1884, 1888)

And there were visitors even in the winter by then too. (1884)

That continued into the 1890s. (1997, 1998)

In the first decade of the 1900s the boats were still popular….but there was a cable car too. (1900, 1901, 1910)

The last page of a book copyrighted in 1922 included an annotated map of the falls area that had been created in 1893.

Gleanings of the Week Ending May 26, 2018

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 Secret Science of Shell Seeking – Shells and Sanibel, Florida. Hopefully the sea will not become so acidic that shellfish become less numerous over time.

Old sea ice continues disappearing from the Arctic Ocean | NOAA Climate.gov – Quite a difference in the amount of old sea ice between 1984 and 2018. It’s tough to be a polar bear or any other creature that depends on sea ice.

The secret to honing kid’s language and literacy -- ScienceDaily – Children need enough sleep, playing games, and time without distractions in the background as well as having books read to them…to encourage language and literacy development.

Compound Interest - The chemistry behind how dishwashers clean – The post didn’t address why glass becomes etched by dishwashers over time…so I was a little disappointed. Otherwise, seemed to cover the bases.

Twin Satellites Map 14 Years of Freshwater Changes: Image of the Day – Analysis of observations from multiple satellites to determine where freshwater is changing on Earth. One of the sources of data was GRACE (Gravity Recovery and Climate Experiment) that collected data through 2017. The follow-on was launched this past week (on May 22) - Meet NASA’s New Dynamic Duo: A Pair of Climate Change-Tracking Satellites | Smart News | Smithsonian

Fox Photos Capture the Diverse Personalities of the Wild Animals – We occasional see fox around – entering or leaving the forest behind our house. I’ve never managed to photograph one.

BBC - Future - Pain bias: The health inequality rarely discussed – I’m glad I am healthy….but wonder what will happen if I ever do need medical attention. This post is part of series from BBC Future about how men and women experience the medical system differently.

Climate change broadens threat of emerald ash borer -- ScienceDaily – Here in Maryland, our ash trees are dying now. Many have been cut down this year.

Buyer beware: Some water-filter pitchers much better at toxin removal: Study finds some purifiers remove twice the microcystins from risky water -- ScienceDaily – Evidently the slower filters (and often more expensive) do a better job.

Thomas Jefferson and the telegraph: highlights of the U.S. weather observer program | NOAA Climate.gov – A little history of weather observations in the US….the earliest being in the 1640s. Thomas Jefferson bought his first thermometer about the time he wrote the Declaration of Independence and his barometer about the time he signed it….and maintained records until 1816. George Washington also took regular observations….the last entry being the day before he died.

Top 25 Arid Birds – National Geographic Blog and Top 25 Woodland Birds – National Geographic Blog and The Best of the Top 25: Part 1 – National Geographic Blog and The Best of the Top 25: Part 2 – National Geographic Blog – Birds and more birds! I’m catching up on a lot of ‘top 25’ posts that have been accumulating.

Millennials Begin To Change The Face Of Camping In National Parks And Beyond  - Positive trends – more people camping…and more diversity. Great vacations…outdoors.

Historic Low Sea Ice in the Bering Sea: Image of the Day – Big changes to the amount of ice.

Algae Blooms in Lakes & Oceans Creating Pollution That Harms People, Pets, & The Planet | CleanTechnica – Who want to do anything in green water. Ugh! Another reason to slow the flow and reduce the extra nutrients that we send into our rivers, streams and lakes (that cause algae blooms).

World’s Largest Victorian Glasshouse Opens Doors After Five-Year Restoration Project | Smart News | Smithsonian – It’s easier to the structure of the building at this point…before the many new plants get very large and block the view. The building was originally opened in 1863…and this was it first restoration.

Alligators on the beach? Killer whales in rivers? Get used to it: Large predators once hunted to near-extinction are showing up in unexpected places -- ScienceDaily – Rebounding populations! They are returning to hunting grounds where they were common before hunting caused their near extinction.

Five Tips to Help Frogs and Toads in Your Yard: The National Wildlife Federation – Good recommendations for frogs…and wild life in general. I may repurpose my daughters old ‘turtle sandbox’ into a vernal pool (but will have to monitor it for mosquito larvae)

Why Teenagers Should Understand Their Own Brains (And Why Their Teachers Should Too!): NPR Ed: NPR – After being around middle school students this week…this article caught my interest. I’m glad we are learning more about the teenage brain and can come up with solutions to the problems caused to their sleep pattern by early school start times.

How Seeds from War-Torn Syria Could Help Save American Wheat - Yale E360 – From a seed bank near Aleppo…saving the seeds from the bank by taking them into Aleppo to Lebanon and now Kansas State and North Dakota State Universities developing wheat that is resistant to Hessian fly which has been an increasing problem with climate change (higher temperatures enough that the flies were not killed by the cold of winter, less water) significant enough that US grain yields were falling. Hurray for a diverse seed stock (and the US should take note to develop diversity rather than destroying via monoculture agriculture).

For how long will the USA remain the Nobel Prize leader? Empirical study on historical development allows a prognosis -- ScienceDaily – The graph is not positive for the US. It looks like the UK is recovering from a trough that developed in the 1990s while the US peaked in the 1980s and has been going down since then (the metric being Nobel prizes per year per 100 million inhabitants).

Changes at the Grocery Store - a little history

When I first started doing my own grocery shopping back in the 1970s – the checkers still had to know the prices (no scanners), there was only one kind of bag and it was paper, and I paid cash or wrote a check.

Then the scanners came along and plastic bags although paper bags could be requested. At some point, paying for groceries with a credit card took over from checks. The credit card processing hand changed over the years…from the checker swiping it through a part of the register, to me swiping it through a device, and most recently, to me inserting the chip end of the card into the upgraded device. That finally step has eliminated the signature requirement.

I started using my own reusable bags about 8 years ago and now seldom get the plastic bags any more (and never from the grocery store). Sometimes my husband requests paper bags that we use for collecting paper to be recycled.

The last plastic bags I’ve eliminated are from the produce department; I’ve started taking a reusable plastic bin for those items – weighing them so the checker can easily scan the weight/price for those items. In a recent trip I eliminated 3 plastic bags; I always am pleased when I can take a simple action and reduce plastic use!

Of course, once the Community Supported Agriculture (CSA) season starts in June, my purchases from the grocery store produce department are dramatically reduced.
