Deeper Nature Study: Winogradsky Update

Last time, we had just set up our columns, and were waiting patiently to see what would grow.  5 days into the project, and here are the before and after photos for A and P's jar:


Day 1

Day 5

As you can see, things are growing!  The muck is blacker, and the blackness has spread to the gravel just below the muck level.  Surprisingly, the egg yolk is not attracting much growth--yet--though the egg shell has a fine black mist over it.  The water at the top of the jar is a bit cloudy.

Check back in a few days for more.  Hey, and if you have a Winogradsky column of your own, send along a few shots, and I'll put them on!

And speaking of things growing in jars...I just made my first batch of cranberry/pomegranate "wine" using this kit:





 Hey, it worked!  The results are less dramatic, but much tastier.

Deeper Nature Study: Winogradsky Columns

In the great gold room there were some teenagers

and some gritty sand

and some jars full of sand

and two little boys who didn't use chairs

and some jars and a ghost

and some sprouts, but no toast!



But really, we were winding down from our Winogradsky project.  Yes, you at home can grow lovely pet bacteria in your own jar.  It's easy--so easy that when the teens finished, and the younger kids were totally interested in setting up their own columns.

Winogradsky column (with very watery top) day 1.



We started out at the beach, collecting some samples:  Shells for calcium, water for--well--water, muck for bacteria (we hope!), red sandstone for iron, and some sand for substrate.  Back at the house, Alice had boiled an egg for sulfur...but we were not quite ready to go home yet...

Oh, can't quite see the Storm Trooper.
As we were driving back from the beach, we passed a farm-stand that was closed, and a field that reeked of unharvested Brussel sprouts rotting on the stalk.  Luckily, the ever-stealthy Mr P. had his Storm Trooper Hoodie with him.  He zipped it up so no one would notice him, and stole into the field with his colorfully-dressed friends, plucking a small rotten sprout and a leaf for our nefarious purposes (will it be a better source of sulfur than an egg?).



 Back in Alice's Test Kitchen, we sorted our samples, and added a few ingredients:  Sea salt (coarse), cloves (will they inhibit growth?), fresh water, a magnet to attract magneto-bacteria, and foil for those who want to see samples grown in the dark.

The procedure is simple:

Layer all ingredients in the jar, with an ample supply of cellulose (we used the cardboard from an empty 18-egg box, torn into bits by industrious children).  We started with gravel and sand, added cellulose, egg or Brussel sprout, egg shell or sea shell (crushed), muck from the low tide zone (any black muck or topsoil will do), and odds and ends...a pocket of sea salt, a pocket of pepper, a pocket of ground cloves (anything you can think of!).  And we s-l-o-w-l-y added water, fresh or salt.  Some left lids loose, some tightened their lids.  Some covered the columns with foil for darkness, while some left them in full or dim light.

Since I was busy with the teens doing the project, most of the photos are taken with a younger bacteriologist modeling the process.  Here's Miss C's work:




Note aforementioned ghost.








Isn't it amazing how everything looks delicious in Alice's Test Kitchen, even the muck?





Mr. N and his Winogradsky column--he added a pocket of sea salt in hopes of growing a pink halophile colony.


Youngest boy found the banana a more interesting subject.

 What happens next?  We wait and see what grows.  Check back, and see!

High School Astronomy Books (because a friend asked)


Originally from MacBeth's Opinion website. 
 (Most links are to Amazon...you know the drill.  Links are for convenience.  Most books are available in the library.  Some are available on Kindle!  If you buy a book, Amazon gives me a tiny bit of dough towards books for my homeschool--no pressure, ever).


"And behold, the star that they had seen in the East went before them, until it came and stood over the place where the child was.  And when they saw the star, they rejoiced exceedingly." (Matthew 2:9)
"At the dead of night, two noble planets, Tarva and Alambil, will pass within one degree of each other.  Such a conjunction has not occurred for two hundred years." --Dr. Cornelius in Prince Caspian
"Dear old leopard." --Lucy in Prince Caspian, admiring the Narnian constellations


As a spine:  Astronomy:  A Self-teaching Guide

365 Starry Nights : An Introduction to Astronomy for Every Night of the Year by Chet Raymo (astronomy lessons night by night) .

For the more advanced astronomy student:
With a good back yard telescope, and not too much effort, this is one fun book: The Year-Round Messier Marathon Field Guide : With Complete Maps, Charts and Tips to Guide You to Enjoying the Most Famous List of Deep-Sky Objects by H. C. Pennington (whew!) The Messier objects (about 100 of them) were catalogued in the 1700's by Charles Messier, a comet hunter who was annoyed by "fuzzy objects" that were not comets in the sky. He catalogued them to get them out of the way! His list includes star clusters and galaxies, all fairly easy to find (even with 1700's technology).

Need information about tonight's sky??
Online, Sky and Telescope   magazine is the best source for finding out what planets can be seen from your location and when they rise and set. It also includes meteor showers, comets, etc.

And some good theory books for high school and beyond?

A Quake!




So I dropped T in California on Thursday, and sent Libby to San Francisco this morning, and both miss the very strong quake that just hit the northeast.

Hey, speaking of quake, remember Quake Cereal?  Yeah, Quisp was better.
I guess it's a good day to break out the Earthquake books.

And here's a research project for your older kids today...why is Seismology (the study of earthquakes) often called the Jesuit Science?  Map the quake from its epicenter.  Check for tsunami warnings.  What kind of waves propagate from the epicenter?  Record the impact it had on your area.  Compare with the large destructive quakes which have hit New Zealand, Japan, Chile and Haiti over this past year.  Keep an eye on the USGS website.  Download the earthquake app for android!  It's free (but it will drive you crazy; earthquakes are happening all around us).

Prosaic Post-New Year Post

Resolutions?

I followed through on a resolution.  Once.

Still, why not try?  And why not try a few?

1. Lose weight and excersize, eat better, etc. (not just prosaic, but trite).
2. Learn to spell excersixe (it just gets worse each try and spell check refuses to give me any hints).
3. Read more (finish books I have started and put aside that are now under a pile of other books that I am actually reading).
4. Keep up with chores.

Pretty much.  Sorry to bother you all with a post.

Oh, and Happy New Year!  ;)

How to Catch Space Dust in the Snow (from MacBeth's Opinion)

Every day, the earth gathers 100 tons of dust from space!  You can easily catch an observe some of this minute invasion force, using simple household items--a coffee filter, oven, and a microscope (a magnifying glass may do, as space dust is fairly large), and a magnet.  Since much of space dust is made up of iron, it is very magnetic!  Even if you don't find space dust, you may be surprised by the amount of regular old dust in snow--even fresh clean snow!
Procedure:
Take a bit of fresh snow and place it on a coffee filter inside a cup (cone filters work best).  Allow the snow to melt away, and let the filter dry (you may use a warm oven to aid this process).  Examine any dust left behind.
How much is there?  Can you see any large "dust?"  Use a magnifying glass of a microscope to examine the specks.  Space dust is roughly spherical, having melted on its journey through the atmosphere.  Sometimes, space dust has a tiny "tail."  Sometimes, especially if the dust contains nickel, it looks like Mickey Mouse--a tiny sphere with "ears."  Use a magnet on the dust to determine if it contains iron.
Older students may wish to quantify the observation, by weighing the dust collected (use a fine, digital scale, available from Science Kit).  Even earth dust is heavy, and while snow is naturally dusty, sitting snow will have an increased volume of dust.  How much more concentrated does the dust sample become in one-day-old, two-day-old or week old snow?   Cover some snow to protect it from gathering "new" dust.  Does the volume of dust increase as the volume of snow decreases?  Why?

Winter Hike (from MacBeth's Opinion)


The winter nature hike is a glorious thing!   Pull on your boots and jackets, and don't forget your hat!  Here are a few hiking ideas, and some ideas for your winter back yard: 
Hike a beach, lakeshore, or river bank (carefully!)
Visit the forest right after a snowBe the first to hike a field after a snow
Make snow angelsLook for tracks near water sources
Try Nordic skiing
Go bird-watching early in the morning
Take an evening hike
Star-gaze
Take a "listening" hike--what do you hear?
Examine snow flakes (take your microscope outside so the flakes stay frozen)
Look for the "skeletons" of last summer's plants
Dig for tubers and roots:Jerusalem artichokes wild carrot (caution! must be positively identified), leeks, evening primrose, wild potato, chicory, onions, field garlic, ground nuts, anise root, sassafras, wild ginger, curly dock...
Taste fresh snow
Winter orienteering is a challenge!  Try it!
Play "fox and geese," a game like "tag," on a circular, spoked track in the snow (directions in A Prairie Boy's Winter)
Make snow-shoes, and walk with them!
Look for winter berries--who eats them?  Which berries are eaten last?
Look for last summer's nests
Cook outside and eat there too!
Learn fire building (read London's To Build a Fire)
Step outside during a blizzard (step inside quickly!)
Identify local trees by bark aloneTurn over your compost pile
Take the temperature of your yard--near the house, away from the house, the soil surface, under the soil, in the compost pile...Hang different bird-seed types in different places--who likes what?
Hang suet for birds, too!
Provide shelter from elements for wildlife--bird houses, bat houses, brush piles, old logs, etc.
Keep a record of the weather
Tap maple trees in late winter--boil the watery sap into thick sugary syrup, and pour it on ice cream, pancakes, or even snow!

Back Yard Nature (from MacBeth's Opinion)


Back Yard Nature


Need to get nature study jump-started in your own back yard? Here are a few suggestions!

1. Let the grass grow a bit and do a lawn study. Do you know how many different plants and animals are in a small patch of lawn? Let a small section of your lawn grow and do a succession study. What is growing there after a year? After two years? I can’t tell you how many school children believe that if only we let the grass grow tall enough, it will turn into trees. A succession area will show your children that other plants arrive on your lawn in a variety of ways, not through instantaneous evolution or spontaneous generation.

2. Start an open compost pile and watch things decompose. An open compost pile, not a new-fangled bin, will reveal the mysteries of decomposition, and provide more learning opportunities than you imagine. Last year, a surprise pumpkin patch grew in our compost pile, and I remember a watermelon growing out of my grandmother’s compost pile when I was a child. This year, Yukon gold potatoes are thriving on the edge of the pile. Compare gardening with composted soil, and gardening without it.

3. Plant a garden with vegetables or flowers. Know the names of the plants. Plant something big, like giant sunflowers of pumpkins. Plant something small, like one of the new hybrid eggplants or berry tomatoes. Plant something native to your area, or plant something exotic. If you have a small yard, or no yard, can you visit a relative with more room? I grew up in an apartment, but my grandma Kerr always planted a fragrant flowerbed at her house, and my grandma Collier always had a bountiful vegetable garden.

4. Make your yard a haven for wildlife. Put up bird feeders or nest boxes. Add a birdbath as a water source. Tame the birds—it’s not hard, and the tame birds will provide you with ours of enjoyment through the winter! Try bat boxes, or butterfly boxes, too. Ladybug and toad boxes are also becoming common. Perhaps the kids can design a shelter to attract other wildlife. A simple brush pile may encourage rabbits to move in. If you live in an apartment, look for creative ways to bring nature closer…a nest box on a fire escape can bring a surprise guest!

5. Place large stones or logs in your yard. Let the kids peek under them from time to time. Worms, pill bugs, centipedes and other invertebrates, and some vertebrates like salamanders and snakes, will find a haven in your yard.

6. Know what’s in your yard. Know the kind of grass on your lawn. Know the trees on your street. Learn the names of the animals and mushrooms. Know which of the plants in your yard are edible, and which are not.

7. Add a water garden. These are easy to build, with kits available at garden centers. The sound of running water may bring the unexpected to your yard. Within two hours of turning on our small pond fountain, our first red-winged black bird stopped by for a drink. Since then, hundreds of birds have stopped by our urban plot.

8. Place stepping-stones through the gardens in your yard. Kids like to step on the stones, hopping from one to another, and they will help to keep young plants safe from stomping feet. Place them in patterns, or randomly. Even my big kids don’t seem to tire of hopping from stone to stone around our pond.

9. Set up a small weather station with a thermometer and weather vane and barometer so the kids can predict the weather, correlate the wild visitors in your yard with temperature, pressure and wind velocity.

10. Finally, let your children dig in your yard. Set aside an area where they can dig for treasure, or take soil samples. Perhaps your older children can set up an archeological dig . We found old nails, hinges, and even a piece of "ancient" vacuum hose when we did our dig! See Dig magazine for more fun.

My Novel Life

...meme, courtesy of Red Cardigan. Thanks, Erin...what fun. This'll be fun for the kids, too as a launch point for a writing/discussion seminar.

My Novel Life

1. If my life were fiction it would be set in...an underwater city with a marine research center.

2. Right now I would be wearing...a jumpsuit made from a bio-mimetic fabric that dries quickly.

3. The biggest crisis I would be facing would be...discovering that jellyfish have complex brains that we just never detected, and they want revenge (we are not sure why...!).


4. My biggest joy would come from...an allergen-free atmosphere, a constant ambient temperature, and regulated humidity.


5. The most frustrating daily challenge would be...making sure the kids pick their equipment up off their bedroom floors.


6. Looking out my window, I would see...squid. Giant squid.


7. The other characters in the story would be...3 geeky scientists, a quirky literature professor, monks in the St. Brendan's-Under-the-Sea Monastery, 2 humorously competitive graduate students, and a full orchestra. The acoustics at St. BUTS are perfect.


8. An essential element of a happy ending would be...My kids growing up and deciding to raise their kids right here in Sea-town.

See how Lindsay answered, too!

Copywork for High School

One day, when I was a senior in high school, my father read something I was writing for history class, and was surprised: His daughter couldn't write. Oh, I wasn't illiterate; I was just not a great writer. His solution? He would choose several articles from National Geographic Magazine and make me copy them, word for word, until I got the idea. So, long before I had ever heard of "copywork" as a lesson, I was doing it for the sake of my own education. I think it helped, as my grades improved and I tested out of freshman composition when I got to college.

Think your high school student is too old for some old-fashioned copywork? Think again. Just as your youngest students benefit from added vocabulary, spelling and phrasing by imitating good literature, so will your older students benefit from the imitation of great works of literature and technical writings across a variety of fields. Like an artist learning certain techniques by imitating the masters, or musicians learning by listening to the many wonderful recordings available, so writers may learn techniques, a new turn of phrase, strong, subject-specific vocabulary and good-old information from imitating the good folks who make a living by writing, or who write as part of their vocation.

Of course, the copywork does not have to come from National Geographic. As students gain a better idea of their future plans, they also gain an understanding that specific field and endeavors require technical writing skills that are different from the five paragraph essay. An archaeologist does not write a paper that sounds like one written by a musician; a student interested in philosophy will write a very different paper than will a student of social sciences. Here's where copywork comes in. If your high schooler is a regular reader of a particular publication or trade magazine, that's a great place to find a passage worthy of copywork. Perhaps it is Natural History, or maybe Sacred Music, North and South, or Archaeology that interest your student most. Or perhaps you might want to use copy work as an opportunity to introduce him to a new subject, or to reinforce the vocabulary of a difficult course. And for the aspiringing young Catholic writer, nothing beats the prose of the great Catholic writers of our times: Chesterton, Tolkein, Belloc, Waugh, O'Connor and others.

So don't be afraid to assign some copywork for older students; they will benefit as much, if not more, than the younger children.

Peroxidase in Action

This is not the actual project, but just a quick qualitative run-through to test the efficacy of the horseradish peroxidase before going on to the actual chemistry. As with any organic extract, the concentration and potency of the enzyme may vary. Horseradish is out of season (I had to go to several specialty grocers before I found it), and it has to be fresh in order to work. I understand the it goes bad quite quickly. So, here's how we tested it on hydrogen peroxide:


I sliced some root section...



and sliced it again to fit into the test tube.




We placed it in a test tube with 10 ml of 30% hydrogen peroxide, and a drop of dish soap to sustain the oxygen we hoped it would produce.



Yay! It produced oxygen and water, slowly at first...



then, quite vigorously.

Tune in tomorrow, for the quantitative experiment (may include fire)!

Narnia Goes Green at The Franklin

There's an exhibit on Narnia, opening Friday, in at The Franklin in Philadelphia. It includes costumes from the movies, props, interactive exhibits (see more by clicking on the exhibit preview video) Sounds great, right? But, disturbingly, The Franklin is using the Narnia exhibit as a vehicle for environmentalism. At least, that's how they are marketing the exhibit. From the website:

The Chronicles of Narnia: The Exhibition takes you on a magical tour where sets, original props, and newly created interactive exhibits drive home a powerful real world message about our stewardship of the environment.

How heavy-handed will the message be? Hard to say, from looking at the exhibits and workshop descriptions, it looks like it's mostly a geology program with a thick Narnian veneer. One part of the exhibit does touch on--you guessed it--man's impact on the climate.

Don't get me wrong: I like the planet, and I love Narnia.
I would be happy to visit The Franklin twice...once for the Narnia exhibit, and once for an interactive session on global geology. But to market an exhibit on Narnia as a "powerful real world message about our stewardship of the environment" strikes me as totally wrong-headed. First, the environment was not Lewis' point. Second, Narnia's environment, at least in the first book, was disrupted by magic, and magic returned it to normal. Earthly environmental issues are not so easily pinned on any one thing, nor are they easily cured (and some would argue, natural processes need no cure). Third, do the curators believe that any child enchanted by Narnia is going to be primed for a lesson in Earthly ecology? Really? I find that children are offended by those who try to so dupe them.

All that said, the exhibition runs through April, and yes, we will go. ;)

Synthetic Ice

Attention ice skaters: Global warming need not keep you from your favorite activity. At the American Museum of Natural History, a new rink has opened using--get this--synthetic ice. According to the website, The rink is made of an artificial ice, or "synthetic ice," surface that allows ice skating blades to glide smoothly. The use of synthetic ice has environmental benefits; natural ice requires a significant amount of electricity for refrigeration, and the synthetic surface is made of 100% recyclable and non-toxic materials. The synthetic ice does impose some skating limitations: skaters cannot use skates with double blades.

Weird. Doesn't require cooling. Sounds like fun, though. And he rink at the museum is so pretty!

The Misanthrope

Juilliard's 4th year drama students' production of Moliere's The Misanthrope is delightful. We saw it last night, after waiting an hour for (free) stand-by tickets, which I understand are fairly easy to get on a Thursday night, but may be more difficult over the weekend. Still, it's worth a try. Check the Juilliard Calendar Website for details.

So, is 400 year old French satire worth seeing? Yes, in a PG13 sort of way. If you might be put off by gold lame 2-piece swim suit, and a 20 minute flirtation scene with Celimene and her shirtless suiters in a pool, don't bother. It sounds gimmicky, I know, and when I read the preview in the Juilliard Journal, though my curiosity was piqued, I had my doubts. Moliere, for all his verbal brilliance, did not leave stage directions, so any production lends itself to some odd and unexpected variations in scene and setting at the whims of those who make such decisions. (I have a fear of modern theater...will I be treated to Shakespeare on roller skates? Sophocles on stilts? Moliere...in a pool?) The set has some of the expected elements: French doors, long drapes, winding staircase, fine upholstered furniture; and then there sits the pool, front and center, on stage, complete with a monkey-fountain. The play begins, and...

The pool works seamlessly as an integral part of the set; and it works not just because of the unexpected swim scene, which enhances the comedy, but because of the comedic timing of every word and motion, in, out, and along the edge of the pool. The students have an uncanny sense of space and matter--solid, liquid and gas--and use it all perfectly. Those audience members seated in the "splash zone" were a bit surprised, I suspect, but it was all in good fun. The play, pool and all, is perfect. The lines, an English verse translation by Richard Wilbur, come so naturally to each actor, you'd think they spoke in rhyme all the time.

I am reluctant to post reviews of the individual cast members, as they were all unique and well-suited to their respective roles. I will say that the young man who played the dark and brooding lead character reminded me of a cross between my son Trip and Keanu Reeves. And we all know how misanthropic Trip can be sometimes (like when he played the demonic tempter in Milton's Comus)...

Oh! The costumes...can we talk about costumes? Is there anything more fun than French fashion? The frills! The embroidery! The shoes (on the men)! The hats! The unmentionables!

I just want to add a bit about the ending, without giving it away. After all the lines are said and the main characters have left the stage, the supporting actors are left, and together create silently, and with minimal movement, the most comedic moments of the play. Thank you, Group 38.

See it if you can.

Granny's House

No matter how old the kids are, they enjoy visiting with Granny. Today was no exception!

They took a dip in the pool.



The horse-next-door came over to say "hello," and to nibble on the day-lilies!



They had a bit of target practice...



"Lock and Load"



Clothespins make great targets!



This one is shot clear through.
(A rifle-woman should always keep her nails well-manicured for close-ups.)



They thought wind-chimes might be excellent targets too, and they were!
Wind-chimes give you a nice melodic "ping-dong-ding" when hit.



And no trip to Granny's is complete without running out to the ice-cream man ;)
