Plankton Tow

Tammy and I figured out a potentially cheap way to make our own little plankton tow which we could use to make monthly or biweekly plankton community surveys. Real plankton tow nets run $150+ for a small one (I’m hoping we can “buy” one off a pair of retiring professors). We converted a small meshed carbon filter bag for an aquarium to use a hanger section to hold it open. Makes a 3″ diameter, 12″ long net. We tested it briefly this afternoon. The results? Well for $5 it worked decently. We got a few critters, including one copepod, three gastropod veliger larvae, three naupliar crustacean larvae and this mystery creature.

Unfortunately the photos of the other creatures did not turn out very well.

Juvenile (not larval) brittle star of some sort? Although it looks like it, brittle stars have 5 arms…this has 7 maybe 8.

A small or juvenile pycnogonid (sea spider)? Algae? Pollen? ????

This critter has a diameter of under 0.5mm (it’s diameter is less than that of a 0.5mm mechanical pencil lead — very precise yes?) and this shot was 45x through the home microscope, using extension tubes to jerry rig a system to mount the camera to the lens. I’ll have to see about borrowing one of the eyepieces from the school scopes and see if I can get a slightly better result using their probably better optics.

Johann’s Journal – Science Week

Last week we went to Providence for two science conferences. I had fun. I sat in on some really neat talks. One was about lobster larvae and another was about Alaskan oyster farming. I ate mussels. I worked behind the front desk. We went to the beach party and had fun playing all the games and contests. I got a special award for helping. I made lots of friends.

The End.

Johann joins the NSA

Last week was very busy for us here. I volunteered to help out one of the people at the University who was in charge of organizing and putting on the NSA conference and the Benthic Ecology Meeting which were held back to back in Providence. Ostensibly I was supposed to be there primarily for IT support, but ended up helping with a variety tasks from stuffing bags helping people overcome issues with their presentations, to making lunch runs. Truth be told it was exhausting, but very fun – of course now I am paying the price for missing a week of school and school work…but it was worth it.

The organizer of the conferences knows Johann’s love of science and was very generous, providing Johann and Tammy with passes to get into the event and attend talks. As a family we attended a number of the talks, but the whole family ended up volunteering behind the scenes, stuffing programs and helping hand out newsletters, sell raffle tickets, etc… On Thursday the closing NSA evening event and opening Benthic Ecology Meeting event was a viewing of the IMAX movie Volcanoes of the Deep Sea with opening introduction by NSA member and deep sea biologist Richard Lutz. Richard also had a 20 minute question and answer period afterwords with several questions from the few kids in the audience including a pair of insightful questions from Johann.

We all had great fun, especially meeting some of the wonderful people involved in the meeting and attending it including Kathy Johnston, Richard Lutz, Sammy Ray, Roger Mann, Ken Chew and many, many others.

Johann and Tammy were invited back by everyone to the Saturday evening event to close the Benthic Ecology Meeting – a Beach Party in the hotel ballroom. Johann had a blast with playing volleyball with all the scientists and grad students. It was great fun and hilarious to watch the beach balls fliying into the chandeliers. (My legs are still killing me from all the running and diving.) They also had “Benthic Twister”, limbo contests, a Hawaiian shirt contest and a hula hoop contest. Who knew Tammy could hula hoop for hours straight?!

The highlight of the evening however for Johann was his receiving a certificate of appreciation and participation from the organizer. He had a photo taken with all the volunteers as he received his certificate. We will hopefully be able to get a copy of the photo soon to post. The certificate is now going up over his study desk. As one of the PhD students said “Wow, he’s gonna have a better C.V. by the time he’s in high school than I have now!” Heck he’s gonna have a better one than I do!!

Women Scientists

There is a meme out there for naming women scientists. Well with Johann’s scientists cards and his love of science history as well as science, we felt like playing along. So here are some of the scientists that we came up with, most of them off the top of our heads:

While most of these we came up with without resources, it helped for some of them that Johann has his “Scientist Trading Cards” list, which all of these ladies are on. I figure his lists are the equivalent to “class notes” for us. When we have time maybe we can do a part two… that and go back and hyperlink these to bio pages and lab pages. ed. Done!

Oh and for the record Penny Boston and Diana Northup have some of the coolest named study subjects (at least for Johann): Snottites and phlegm balls.

S’not funny. That’s what they study… no really.

Codes

I discovered that Johann loves solving code puzzles as much as I do, so I’ve been using that to make repeating the multiplication tables and studying spelling words more interesting. I did several puzzles using addition problems to provide the numbers in the legend, which, when used, could translate the spelling words. When he expressed an interest in Morse code, I used that to encode the words. The I Spy Mystery computer game we got for him had a different alphabet code of dots and lines, which was also fun to use.

Once Johann has decoded his words he has them all memorized, in part because of his heightened level of concentration. I’ve had to make simple concepts more complicated in order for it to be interesting enough for him to stop and think about it before. He had a mental block on grasping 2+3=5 until I taught him 20+30=50 when he was little.

In my many hours of boredom in the 6th grade, I taught myself to write backwards. Now I have a use for my untapped talent. In the past I’ve written messages backwards to Johann. He would run into the bathroom to use the mirror to read it. It was a fun game.

In preparation for his last spelling test, I wrote all of his words backwards on a sheet of paper and gave him a mirror. He sat at the table, held the mirror at the right angle, and copied all his words frontwards. He was ready for the test then, but he asked me to make another backwards worksheet, since the first one was so much fun for him. So I created a crossword puzzle, where the words were already in place, but backwards. I made a blank crossword puzzle for him to fill in. I got him started with the first word and he happily spent the next 20 minutes using the mirror to complete the puzzle. Once he had written each word letter by letter, he read it out loud to himself for reinforcement. He loved that one and asked me to do another one for the next set of words.

Our last big deciphering project was for the multiplication tables. True to what he has inherited from me and Eric, Johann has an extremely low tolerance for repetitive, mundane tasks. But I am determined to have him know his multiplication tables inside and out. My third grade teacher did that for me and it benefited me greatly.

While I was poking around Enchantedlearning.com looking for something new to do with Johann, I came across the numbers written in Chinese. A web search helped me find two other educational websites with even more information on writing numbers in Chinese. I learned how to do it, then taught Johann. Each day’s math consisted of one part of the times tables written in Chinese until we had gone from 1 to 12. Johann’s job was to translate the problems and write the correct answers to the equations. He had the idea of writing the answers in Chinese also, which improved it and made it more complete.

This turned out to also be an exercise in accessing and retrieving information. The entire multiplication tables were already in his head in the form of the Schoolhouse Rock songs. I taught him how to use the songs when he got stuck.

Now I’m looking for new codes. It’s going to get harder and harder to top the previous project. For the next spelling test I think I’ll use braille.
