Retrofitting the school's basement into a root-cellar

We grow a lot of our own food here at MHS, but of course you can never have enough local food, and one of the limiting factors to local food being served in the cafeteria is storage space. We would grow more if there was a good place to store it. I have fond memories of a box of potatoes being stored in a air-conditioned closet just off the computer lab that also housed a Scanning Electron Microscope. Frankly, there's just not enough room in that closet with the SEM.

So my students took on the challenge of designing and mathematically modeling a root cellar for the school. We found an appropriate site, a portion of the basement accessible by a bulkhead, that we could retrofit to become a passively cooled root cellar space*.

The kids were totally pumped! They dove into that math, the concepts, modeling the heat flow, taking data down there. It was awesome. They came up with a plan. We met with the principal, the head custodian, and a grant writer. They were all on board - provided that we do all the necessary fund-raising, and got all the necessary permits.

All of that momentum and positivity slowed to a dead hault when we met with the building inspector to make sure that we could permit the retrofit, and then his analysis was a total buzz-kill. (That's gotta be a tough job, to be fair: telling people their idea is literally "not permitted"). Not only could we not have students down there, but we would not be allowed to put up any walls to portion off the space. It's frickin HUGE down there, and there was no way we could passively cool the entire space to the necessary temperatures. Why not? There was  no sprinkler head down there. There was also no standard-sized doorway into the space. The bulkhead on the outside leads to a mini-door, maybe 4 ft tall. Bummer. Not exactly up to code for what we wanted to do down there.

So I thought the project was dead. Great idea. Impossible logistics.

But when I ran into the head facilities guy, Thom Wood, who was also at the meeting with the city building inspector, I was shocked to hear his impressions of that meeting. I was all "Bummer about the sprinkler system, and the no building walls down there, huh?" And he was all "What do you mean? We can easily just add another sprinkler head for like $100, no big deal. Also, I was thinking we should call up that company from Barre that cuts cement. We could get them down there to cut the foundation so we can have a standard-sized door." I was aghast with delight. What!? This was possible again? Sweeeeeeeet! Thom Wood: unexpected hero of the day!

So we're still working on it. Here's where things stand presently: one of last year's juniors is still working on this with me as an independent study. We've continued to meet with Thom Wood who outlined the process of getting all the necessary permits, starting with the zoning permit, since we'll need to build a little shed over the now-existing bulkhead. We've met with the city zoning permit guy and he was like "You don't need to present this to the Design Review Board. Just send me a letter with sketches and a description of the outside." No problem, sir. No problem.

The student got that done, and now we're on to the Building Permit application, which will be a little more mmmm... in depth. But hopefully we'll have that done by December. We're still chugging. I love this stuff!


This is what the bulkhead looks like now.
This is the student's rendition of the bulkhead with the shed-entrance to the root cellar over it.







*"What the heck is a root cellar?" is a question I run into more frequently than I would have expected. It's a cool space (usually 35-50 degrees Fahrenheit) used to store vegetables like carrots, potatoes, cabbage, onions, etc. It was how people stored food before electric refrigerators were available. Typically built into the side of a hill, or a basement, the naturally cooler temperature of the earth helped to stabilize the temperature at a slightly below comfortable level.

Peer Tutoring Update

The peer tutoring program is up and running! WOO HOOO! Well... halvesies anyway. Specifically, we have started to match people up with one-on-one tutors; they've started to meet, and the feedback thus far is VERY positive. *whew* :) win-win-win (if you will).

The drop-in tutoring: meh, not so much. I think if we had a school larger than 350 students for 4 grades, we might actually have enough students to cover every period and be able to keep that room open, but as it is, it just hasn't come together - though not from lack of willingness on the part of the students.

Perhaps if we had a good start-date for that it could still get off the ground, but what we're finding is that some students we would otherwise have put in the drop-in room, wind up being the only one available for one-on-one tutoring a particular student. And THAT is where we think the real benefit occurs. So, I guess the one prong of this fork is eating the other. (Bad analogy? maybe. But I'm leaving it for now).

Starting a Peer Tutoring Program


According to a survey we administered in the spring of 2010, the majority of students prefer to receive help from their peers! Thus confirming what I or any person in a high school could've told you without the survey.

We teachers also know that probably the best way to understand something is to have to teach it.
For some reason I despise the phrase "win-win-win", but, for better or worse, it applies to this situation. Kids who need help get it. Kids who know stuff are pushed to get it better. Teachers who don't necessarily have lots of extra time at school get freed up a little bit. Sweet.

But I'm sure I don't have to make a case that a peer tutoring program is a good idea. It's pretty much self-evident.

We're launching it tomorrow at the class meetings. I'm pretty sure this program is going to live and die by its PR. We need a critical mass of kids who both want and need help, so we've gotta get the kiddos to sign up. There will soon be a blurb on the school website, going home to inboxes everywhere in the "eNews", and every teacher and guidance counselor will be given soft & hard copies of the forms for signing up and the forms for requesting help. We've also developed an agreement form that outlines that tutors won't do the work FOR the tutee, etc.

We're trying a two-pronged approach. We're creating a Drop-In space manned by seniors who are "generalists" and can help read through a paper, or give quick advice on a math problem, etc. In addition we'll be matching kids to meet one-on-one (in some teacher's unused classroom perhaps?) on a weekly basis.

In case this is interesting to you, I'm just going to copy/paste the forms we're using here. Feel free to steal them for your own purposes.

Rural Teaching: Breaking the Isolation


It behooves us as teachers to be the best we can be. (Wait, am I in the army? Ok, no.) But it's difficult to critically analyze one's own teaching when... say, you're the only physics teacher in the school. For all anybody else knows you could be espousing that cherenkov radiation was Newtonian Mechanics and no one would be the wiser. Not that anyone would really do that, but the point is we could be totally missing the mark and subsequently go unchecked.

Also Cherenkov Radiation is really eerie! Check it out:

Here is where I must confess: I am addicted to feedback. I need other teachers to lay their eyes on my plans, my students' work, video of my classroom, and I crave their thoughts. Not because I doubt the value of my own work, but because there is so much to be gained in the exchange of ideas and views. If we are going to move the profession of teaching to a healthier plain of existence it must be a collaborative effort.

And just because I'm the only one at my high school is not a good enough reason to not get what I need. If I'm not getting what I need, it's because I'm letting myself starve. I refuse to be a victim of my own choices.

This is why I'm starting a Central Vermont crew of physics and chemistry teachers. It started with my friend (and first year physics teacher) Meghan and I last year getting together because she had curriculum ideas and advice for chemistry (and it was my first year teaching chemistry), and I had curriculum ideas and advice for her teaching physics. This year she has moved on to a different school, and it has taken two people to fill her position. It looks like this crew of four (the two new folks, Meghan and I) will be the crowd that starts this. I'd like to invite some other local physics/chem teachers. We'll just have to see where this goes.

My fear is that we'll meet a few times and then it will peter out. Here are my hopes for this group: That we would

  • each come away feeling challenged and inspired
  • each come away feeling like we helped someone
  • get recognition or credit from our school districts for this work (not sure how yet?)
  • get some kind of sponsorship from a local bar or restaurant
  • have good mojo. You know... that we'd actually get to know and like each other.

Next Meeting: September 21st. I'll let you know how it goes.

Mysterious Optical Phenomena (that are so tasty!)

My research into diffraction and holography has thrown me into a vortex of new ideas that are eating my brain. I will list them here along with my favorite line from their corresponding wikipedia articles.

Parhelic Circles "Even fractions of parhelic circles are less common than sun dogs"
Anthelion "How anthelions are formed is disputed."
Solar Glories "Glories are not conclusively understood."

What is Science For?


Diffraction & Holography will just have to wait because there's something I need to post about like right now.

I recently spent a week in the woods at the Roots School, which is a place where people who are skeptical about "progress" can gather to learn primitive skills. I went almost directly from low-tech living to a science teacher's convention and the transition was simply too much for me. I broke down in tears on the southbound train taking me deep into the contiguous suburb that exists from Boston to Washington DC. Awesome. It was too much. I had lost faith that science as an institution was good. Science had become the enemy, particularly as I thought about the applications of scientific principles in the modern world. Would my students go on to invent the next equivalent to a nuclear bomb? Genetically modified crops that destroy entire species of insects or lack the capacity to reproduce solely for the purpose of making a corporation lots of money? I might even go so far as to throw skepticism on the Lowell Wind Farm project that will displace the native bear population. Where do we stop? And how do I know if my students will be any better prepared to make morally sound decisions with their science? How do I know that they won't sell out and use their science for their own benefit at the cost of public health or wellbeing? Yes, it was questions like these that ate my mind at that moment. What was I doing with my life? Would it actually lead to genuine good?

While I was trying to discretely get my emotion out through my ocular aqueducts the lady across the aisle from me turned to me and said, "hey, would you mind holding my sleeping kid while I go to the bathroom? Oh goodness! I'm so sorry to have bothered you while you were having a moment. Don't worry, I have moments all the time." I thought it was somehow fitting that while I struggled to believe that the future would be good with all the science I was stuffing into kids' heads that I got to hold a small child.

At the science conference people agreed that science posed a potential danger, certainly, but that in the end science was just a tool. The analogy that became popular was one of a chainsaw. Certainly science is neutral, neither itself good or bad, just a tool in our hands, but a rather powerful tool. As a science teacher it was my job to pass out chainsaws to students, and instruct them on how to use them. However, very few science teachers, engage their students in dialogues regarding appropriate use of the chainsaw. Is it good to use in the house? with small children? etc. You get the picture.

I will put it out there that one fellow actually espoused the idea that "science will save us." I didn't tell him this, but I find that idea laughable. Here I will quote Einstein: We cannot solve our problems with the same thinking we used when we created them.

It seemed to me that science was a blind and wandering child in the woods, aimless and stumbling. And the medical field had the distinct advantage of having clear goals. Where was the rest of science and technology going? What, then, are the goals of technology? At the time I would have said that it is goal-less.

But last night I had a conversation with a friend at a party about this topic, which I feel like shed a little light on the situation.

"Wouldn't it be great," I said, "if all science and technology were aimed at simply being delightful, making life more beautiful. Perhaps it could be used to make art or toys. Or perhaps it could be used to build relationships or make life more funny. Science should just really be used to make people happy. It seems like the aim of technology is to save us labor and time, when really, as long as it's not abusive or under compulsion, labor can be satisfying."

"Well, that's just the trouble" My friend said, "That is the goal of technology right now, to make people happy. The trouble is people don't know how to be happy."

POW. There it is. Technology is currently attempting to make us happy. But we just don't know
what makes us happy. We're not here talking about pleasure, you know: being drunk, high, or having sex. We're not even talking about cream-filled doughnuts or green jello. We decided we'd call that pleasure. But what about happiness? I asked him, "What makes you happy?"

He said he didn't know. He was one of those people. It's an important question, but he didn't know the answer.

So at the risk of looking like a sap I will make a short list of times I can remember being really happy:

  • Sitting with my friends, Amanda, Will, and Dan at Fresh Tracks Farm while the sun was setting over the winery hills, talking about life and the summer.
  • Making strawberry jam or relish or canning beans with my mom and my sister
  • Discussing scientific developments with my Dad
  • Standing still in the woods behind my parents house listening to the wind in the trees
  • Eating out on the deck at my parent's place
  • Walking anywhere in the woods and hearing a wood thrush
  • The first time (or any time really) you finally get a flame going from a bow drill
  • Reading C.S. Lewis and quietly having your mind blown
  • Laughing and laughing and laughing with my friend Biz
  • Learning about evolution and fossils at the Natural History Museum
  • Hucking a frisbee deep to someone in the end zone
  • Seeing kids' faces light up when they finally understand
  • Imagining, assembling, and troubleshooting a machine until it finally and blessedly works
  • Running laps around the church basement and rolling on the floor with laughter with Naomi, who is 4 years old
  • Writing poetry or music that I enjoy but don't feel compelled to share
  • Expressing myself through music to God
This is what life (and technology) are about. I think I may have my students do some exercise something like what I just did, making a short list.




True Confessions of a Physics Teacher


I know what you're going to say. It's my job to know these things.

But I will confess, there are so many things to know in physics that it's easy to sort of mmm... pass by topics or ideas that are less intuitive, particularly if they're not that interesting. I've finally come to accept the fact that I haven't grappled with certain standard ideas in physics enough to "own" them in a way that I can explain to students. So this is both a record of my confession and my repentance, meaning I'll list the topics here that have eluded me to some degree and I'll write a bit about them after
I've researched them properly and feel like I own them.

The Hunter and the Monkey Problem
I know... this is classic and I really should already own this, but whatever. Here we go. Here's the gist as put by this website.

When hunting the wiley Stuphedwithstuph Monkey the hunter is always faced with a problem. The Stuphedwithstuph Monkeys have developed a sixth sense that allows them to let go of their branch the instant that a bullet leaves the muzzle of a gun. The age old question among hunters has been "Where should a hunter aim to actually hit the Stuphedwithstuph monkey?
A) Above the monkey.
B) Directly at the monkey.
C) Below the monkey.
The hunters have always believed that they should aim beneath the monkey so that the monkey will drop right into the path of the bullet. Individual hunters all disagree when it comes to how far below the monkey they should aim. Since no one has ever successfully shot a Stuphedwithstuph monkey the question has remained unanswered. Where should you aim?

I feel like that website has done a good job of explaining the correct answer, but here's my shortened version. If you aim at the monkey and there were no gravity you'd hit it, right? If the bullet starts to travel along that line and the monkey lets go at the same instant, both the monkey and the bullet will have deviated from that original line (B in the picture) by the SAME AMOUNT because gravity is working on them equally. Thus, it doesn't matter how far away you are, given enough time and space to fall, the bullet should eventually hit the monkey if you've aimed directly at it originally. At least that's how it works theoretically...

Ok, that took a little time... and in attempting the next topic: diffraction and holography I got bogged down in Instructables and subsequently got inspired to make a ferrofluid. So here are some other topics I hope to research and post about soon:

Diffraction and Holography
Fresnel Lenses
Capacitors in (RL circuitry)
something about standing waves bothers me. Not sure what exactly it is yet.
Virtual Images and the Eye
