$100 per inch

What a horrid day yesterday! Fell asleep on the couch the night beore working on a take home quiz for chemistry. Woke up sore and stiff, still had to finish the take home quiz, so skipped breakfast (Dumb!) Got out the door in time to get to class on time, but didn’t count on a dog running across the road from between some bushes. Go left and I’d hit him for sure, go right and I might squeeze by… So, brakes and shift right….

WHAM!!!

Unfortunately I misjudged the distance to the sign on the side of the road. Not by much mind you, but those 6″ will cost me a $100 each in a deductable. The sign was still standing but the passenger side mirror is gone save a stump of plastic and six wires sticking out at odd angles. If that was the limit of the damage it wouldn’t be too bad, but that wonderful — still standing — sign also scraped the passenger sliding door and the rear quarter. Brother.

Still, the dog–ungrateful of the sacrifice–was nowhere to be seen, and I was alright. No injury to anyone but the car and my day. Off to Chemistry, now running late. Ah well, at least tomorrow will have to be better.

Diving Into Antarctica, Long Distance

This winter has been the season for learning about Antarctica.

Early this winter Johann’s great-grandfather went on a cruise around South America. At home we tracked the voyage on our big wall map and talked about some of the sights, cultures and especially animals we would encounter if we went to those locations. While his girlfriend was visiting some of the South Atlantic Islands, Great Grandpa took a flight over the Southern Ocean and the Antarctic Peninsula. We are still awaiting a report from him on what he saw, but we tracked the probable flight path and talked about Austral Summer, the long sunsets and sunrises and non-existent nights.

Now one of the professors from Avery Point, Dr. Patricia Kremer, is in Antarctica aboard a research vessel to investigate salps. Johann met Dr. Kremer during the day long Festival by the Sea at Avery Point. She was in one of the labs giving demonstrations of ctenophore bioluminescence. Johann surprised her when he knew not only what they were (common name is comb jellies), but also knew that they luminesed when disturbed. He told her about the experiment he performed, and had questions for her about the parasitic worms we found in about half of the ones in our experiment. (He also loved petting the Lion’s Mane Jelly that one of the Graduate students had on display in that lab).

Dr. Kremer is co-principle investigator for Dive and Discover’s Expedition 10 to Antarctica to study salps and their role in the changing trophic system of the Southern Sea. Dive and Discover is a program operated out of the Woods Hole Oceanographic Institute and sponsored by the National Science Foundation. The Dive and Discover website has information and educational resources online for all ten of their expeditions (since 2000) and is an excellent resource for teachers and home schoolers as well as anyone who just wants to learn more about the oceans. In many ways similar to Ballard’s Jason Project, only a bit more focused on oceanographic topics. Johann has insisted that we spend time going through all of the expeditions after the current one is done. The team on the expedition puts up daily updates, slide shows, a critter of the day and interviews of personnel on the site, along with the current weather and ocean conditions. Johann was really excited to see Dr. Patricia as the first interviewee.

The program also allows classes and individuals to ask the scientists and crew questions by email. We told Johann about it and suggested that he think about what he would want to ask the scientists. Naturally he focused on the animals. He dictated his email to me and we sent off two questions:

Do salps have parasites like the comb jellies in Mystic?
Are there any penguins around the polar station?

Last night we got a reply from Dr. Larry Madin, the Chief Scientist and co-principle investigator of the expedition. Johann was very excited to get a reply from Antarctica (Penguin Post, we called it.) Dr. Madin informed him that salps do indeed have parasitic amphipods that affect them, and that there were Adelie penguins around Palmer Station, including a nearby rookerie that they visited.

We continue to make the expedition a daily part of school here. Checking first the daily update, tracking the expidition’s location on the map and comparing the weather there with the weather here. We also take a look at the slide show, “Dive Deeper” and the “Critter of the Day”. The critter of the day invariably leads us to our books to find out more about the critter. One of the highlighted critters — a copepod — led to us doing a predator/prey experiment. Afterward we both were running around the house as copepods trying to catch a variety of food items, including Tammy, who we “captured” by tickling with our maxillipeds (specially adapted appendages near the mouth for gathering food). It’s a game we’ve played before, but whenever copepods come up, it always leads to either that game or an often humorous discussion of the importance of copepod poop.

The House of Fun

Eric and I both love science. Johann has the same innate ability and curiosity and has picked up the bug of enthusiasm from us. It’s good that he is advanced in math and science, but it sometimes makes him a handful, just like we were. We are always searching for new material to keep his mind occupied. Or as I like to say: he needs a lot of brain food. Homeschooling gives us the flexibility we need to continually challenge him. I still can’t believe there is no science in the Connecticut public school curriculum until the 4th grade.

Even if we weren’t homeschooling Johann, we would still do all the science activities we do, because we have so much fun doing these experiments together. We got an ant farm this past summer and conducted some ant behavior experiments. We raised butterflies again. I’ve taken Johann on countless nature walks. We often collect treasures off the ground, but at the same time, we are always observing. Eric took Johann outside to track animals around the building and found the footprints of cats, a deer, a skunk and a few rabbits. We made a marble contraption that goes around the apartment and tested which marbles go faster through the tubing and why. Johann learned more physics from the pulley system we set up from the ceiling and the cable car kit we had on the railing.

During an evening walk by the river, we noticed something bioluminescing in the water. Johann wondered what was producing the light. We thought about what animals we know live in the water there and which ones were capable of bioluminescence. Johann guessed it might be the comb jellies (Mnemiopsis leidyi). So Eric and Johann collected comb jellies near the local marina, brought them home in a bucket and we conducted an experiment based on the hypothesis that these critters were the ones bioluminescing in the river at night. We guided Johann through the experiment and figured out how and why they were bioluminescing. While we walked back to the marina to release the comb jellies, we walked him through the scientific process and he even wrote a summary report of his findings. We had him draw pictures of everything we did. When we can we like to allow him to learn the answers on his own, rather than just give him the answers.

After Eric learns something in oceanography or biology that we can boil down for Johann, we find a way to turn it into a family outing or an experiment at home. Johann discovered Eric’s litmus paper and wondered what it was for. Eric explained what he was using it for at school. The obvious question was, “What is pH?” Eric defined pH as measuring how acidic or alkaline something was. “What is acidic? What is alkaline?” I suggested we relate it to liquids Johann knows well: orange juice and milk. So we tested those two liquids and compared them. Of course Johann was curious about other liquids. What would they do? Next thing I knew, we were testing every liquid in the refrigerator and the pantry to measure their pH. Another day we tested our rain water and compared it to tap water and filtered water. We talked about why our rain water was so acidic (pollution).

We all went to Ender’s Island with a seine and conducted our own population count of the fish there in the shallows. We had a wonderful day at the beach and learned even more about the animals that live along that protected area. Eric’s day long field trip collecting data on the tidal levels of the Sound became bathtime fun with a contraption Eric made out of PVC pipe, a cork and a skewer. We measured the change in the level of the bathwater using Eric’s homemade tool when Johann stood in the water, versus when he sat in the water. Then we took measurements with Eric in the water. Then with both of them in the water. Eric used that demonstration to explain what he had done on his field trip and why collecting that data was important and how the scientists use the information.

Johann and I made ice cube castles using salt to hold the cubes together and later watched which ice cubes melted faster: the one in the bowl with the salt, the one by itself, the one wrapped in aluminum foil or the one wrapped in plastic wrap so that we could study the effects of salt and insulators on ice. With the melting ice cubes experiment we graphed our results. We froze one bottle of colored water and kept one at room temperature to illustrate how water expands when it freezes. Eric and Johann weighed bottles of cold and frozen water and compared them to the weight of a bottle of room temperature water. Eric and Johann did some water density experiments during bathtime with bottles of water, salt water, soda and diet soda, observing which ones sank and why. Eric put baking soda into the bottom of a tall glass, added vinegar and then poured out the carbon dioxide to put out a candle flame. We put baking soda into a balloon and put it over a plastic bottle with vinegar in it. After we shook the baking soda into the bottle, the balloon filled with the carbon dioxide that was produced. Johann loved those last two experiments so much that we did them multiple times.

One day another issue of Zoobooks magazine about bears came. Johann wondered how fast other animals run in comparison to a bear. Eric went to Google and found all the stats on the animals Johann wanted to know about. Then they created a bar graph that Johann colored in so he could clearly see which animals are the fastest and by how much. Our upstairs neighbor, who studied science in college, told us about an experiment his dad did with him when he was little. We made a little boat out of half a cork, some toothpicks and a birthday candle. That was placed in a bowl full of water. We lit the candle and put a short glass over the boat slightly into the water. It was fascinating to watch the water rise inside the glass as the flame burned up the oxygen. When the candle went out we had created a vacuum. Johann loved the suction sound as we took the glass back out of the water. We did that experiment at least 6 times before he was satisfied.

Our upstairs neighbor came down to hang out with us one afternoon. We showed him some of the science experiments we had been doing and Johann’s wooden dominoes toy that we got as an extension of the marble contraption. He jumped right in and played with us for a couple of hours. He said he’s never seen a kid as turned on to science as Johann is and he loves coming over because we always have something science-related going on. Our home was dubbed “The House of Fun” by our friend that day. While we are homeschooling we want to continue to keep science accessible, fun and magical. I overheard someone complain that our society isn’t producing any more Einsteins or Monets anymore and why was that? How can we if our public education system crushes the kids who are advanced, curious and always questioning? Those are the ones who might have been the next Einstein or Monet. Johann has said many times he wants to become a scientist when he grows up. What his focus will be changes, but he always wants to be some kind of scientist. We intend to keep it that way. And how could we not? After all, this is the House of Fun!

Classroom at the Beach

Johann is having an impromptu Shanti School (the name he has given our home school) class at the beach. Here he is talking to Tammy and another regular at the Enders Island beach. They had a good 15 minute long discussion about the food web of the ocean and the sound in particular. Together they collected crabs, shrimp, snails and a few small fish fry from around the seaweed clumps.

One of the nice things about Shanti School is tht it is everywhere. It doesn’t stop because we aren’t in our “school room” and while there are regular lessons now, we still have pick-up lessons when Johann shows interest in a subject or item. The lady in the picture above was impressed, because Johann knew that Green crabs were an invasive species from Europe, and that he even could describe how they migrated to our coasts. She said most locals (she’s from Stonington which you can see in the distance in the picture) don’t know that unless they’re fishermen. It was great talking to her for all of us. More confirmation that what we are doing for Johann is not holding him back, but helping him.

Palaeography

The British National Archives has a great section of their site with a tutorial on Palaeography — reading old handwriting, 1500 to 1800. (I thought I had found this by way of Journalisimo, or Moleskinerie, but I can’t seem to find it mentioned at either one now…maybe it was ??? ) Included in the lessons are a number of documents from their collection with interactive transcription tests. You are presented with the document line by line and given a text box to enter the transcription into, which is then checked for accuracy.

As I was exploring this, my 4 year old came over and thought it was a great game. He picked up his magnifying glass and started “helping” me make the transcriptions and asking me about the document. After explaining that these were images of very old writings and how writing has evolved over time, he caught right on — in fact he took over. Now his homepage includes links to the palaeogrphy page right beside Disney, PBSKids and Nick Jr.

We have turned the easier pages (a bit subversively) into a writing exercise. Johann is given the page to be transcribed (printed from the provided PDF) and then writes out each line in one of his notebooks. My wife or I then check his transcription, not so much for accuracy of the transcription as for his own letterforms.

It has turned into a wonderful tool, since he views it as a bit of detective work and enjoys the entire process. I was a little concerned at first that the old letterforms and spelling might be distracting or even undermine his own lettering. Fortunately, that has not proven to be the case. He already has a solid writing foundation and understands that these are old forms and no longer accepted in general writing. I do fear that we may have introduced him to ligatures a bit prematurely and may be seeing them in his own writing in the future — but is that really such a bad thing?

He is a bit thrown (as am I at times) by the interchangeable use of “u” and “v” or “i” and “j”. Some of the abbreviations — ommitting an “m” or “n” by putting a wavy line above the preceeding vowel — also give him a bit of a pause. Then again he does understand that “ye” is not “y” and “e” but is really the old english y-form of “Þ” and “e”. Þ (the character thorn) is pronounced “th”, so when we see “Ye” on modern signs they really mean “Þe” which is really “the” and is pronounced thē or thə not .

On a side note, am I mistaken or is there no SGML character entity for e-macron (ē) or schwa (ə) ?
Surely with their heavy use for liguistic purposes this is an oversight?
