At the beginning of the year I had this great plan for my Experimental Physics course. We could build cider presses in the fall (tis the season), and use them as a vehicle for learning about simple machines, force, and torque. Sounds brilliant, right? Engaging! Interesting! Culturally relevant!
Buuuut yeaaaa... Oh dear. They're still not done and it's quarter 2 now (yikes!). We have the school harvest festival on Tuesday, and we were hoping to get them TOTALLY completed by then. That may still happen - we just have some pieces that need to get welded and then attached, and BOOM. Done. And I, for one, will be very pleased to let them go. Btw, we're auctioning them off... more news on that to come.
With the imminent end of this gigantic process just around the corner I've been reflecting on how I would do this differently next time. Let's just say, there were several things I would do differently should I do this project again. Here were the problems and their potential solutions.
1. The groups were too big, thus too many people were unengaged.
Next time, the Maximum group size: 3
2. This was pretty much the first thing we did as a class, so I didn't know people's strengths, personalities, and group dynamics.
Next time, I wouldn't do a giant project right off the bat.
3. This class does not meet for 1.5 periods like my other physics class. There's less time in general, soooo...
Next time, I don't have a solution for this :P. Maybe require more out-of-class work to be done on these presses?
4. I allowed them pretty much free reign to choose a design for their presses. They looked at other people's plans, but in the end each group really did their own thing. This made the process much longer and more complicated, potentially more valuable, as well, but not when you have a limited amount of time.
Next time, I would have a more cut & dry plan that everyone follows....
Really? Did I just say that? I think really what I want is to have more time, more flexibility. I like Amir Abo-Shaeer's model where kids are required to put in x-hours of time into the class, and they can come in whenever to get stuff done, so long as they get it done.
Truth be told, I don't know if I would do this project again, unless I was teaching specifically an engineering class. I was thinking about proposing that, but (sssshhhhhh...) I've never taken any engineering courses. Lots of math and chem and physics. Bio even. But no engineering.
While I'm talking about dreaming of other courses, I've been thinking about the possibility of teaching a course I would call "the science of survival", but I'll leave that for another post.

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.

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.

After school ended we finally got the city building inspector to come by and take a look at the basement space that we hope will host the root cellar. He said roughly what I expected him to say: No Students. We will only be permitted to build this thing if it’s faculty only. But then he said some things I did not expect him to say. Specifically, we were not permitted to build walls within the 70’x30’ space. What? There’s no way I can passively cool a space this large to temperatures low enough to preserve food. No way. We would need an air conditioner, and then it may as well be a walk-in refrigerator. Boo. Why? Because of the sprinkler system. Each space would need its own sprinkler head. Gr.
I thought this was the end.
By chance I ended up in Tom Wood’s office (he’s the head facilities coordinator, the only other person on the tour with the building inspect
or), and he seemed to have an entirely different impression. He’s an architect, so maybe he sees opportunity where I road blocks. Regardless, he said, “oh yea, we can just add another sprinkler head for like $100 easy.” Oh… ok. “And we may as well cut the foundation so that the bulkhead entrance from the outside is really a standard-sized means of egress.” Oh! Um… ok! And as long as we’re cutting the foundation we may as well do everything necessary to bring it up to code for children to be down there as well. (And suddenly the sun was shining and happy rainbows broke out over the capitol building... as seen from the high school parking lot)
Meanwhile Tom has put together a line-item in the budget for constructing such a space, totaling roughly $15,000. He said it was mainly put in because the administration would need something to reject some part of his proposed budget, but nonetheless, it was in there. So I told Tom that I could definitely write grants to allocate the $15,000.
It seems I have an unexpected ally in Tom Wood! WOO HOO!
This year I will write grants. And probably next year we will build it.
In my last post I mentioned that KSTF brought in MacArthur Genius Amir Abo-shaeer, who, among other accomplishments, started an Engineering Academy at his school in California. I will admit, I was skeptical at first. That doesn’t sound all that amazing, right? I mean, I have known KSTF fellows who have started engineering programs at their schools. But after I herad him speak to the whole crowd after lunch, I realized this guy really has a fresh approach and something to say. There was an opportunity to attend a Q&A session later on, after which I stuck around to ask him more questions. He and I stood outside the ballroom chatting it up, while we both missed the subsequent speaker, whom we were all slated to attend. Here are a smattering of things I understood from those conversations:
Project-oriented not Unit/Standard-oriented. His curriculum is fundamentally different from any curriculum I've heard of (though I will admit this thought has occurred to me and I dismissed it as impossible), in that he teaches big projects that require an understanding of a variety of physics principles. So each project might have elements from what would otherwise be more than one "unit", but over the course of the year, all the projects will have required any understanding of all the physics principles normally covered in a physics class.
Depth not Breadth. To be fair, he doesn't cover a ton of principles, but he does go into the ones he does cover in detailed depth.
**New thought: I need to create an Alumni survey for those students who come back to visit, to assess what pieces students remember, found useful, did they remember the concepts they learned when they needed them in class? Did they end up referencing my notes at all? What was the most memorable thing from their physics class experience?
No Throw-Away Projects. He only has students do projects that for which the end result is something of an extremely high quality. For example, he has students create a baby mobile, that's so cool looking that they can be sold in a toy store, or auctioned and the money given to a local charity. People want these things. He also has them create a water feature. These items can go for up to $500, but the pieces to create them cost as little as $35. These are items that students, again, could sell they are of such high quality. One of his students reflected to him that after this kind of project he said, "After experiencing this course, I realize that the rest of my education up until this point has been worthless." That's a great endorsement for his course, but not necessarily what we're going for. Amir came to education from mechanical engineering, and he reflected that if we have these students for 13 years and professionals have come to expect that by the end of those years they essentially know NOTHING. That is unacceptable. He thought about it in terms of "man-hours" and if he was an employer with access to this kind of resource he would certainly be using it to do something productive in the world.
Tutoring Model: Some of his students needed funds to travel for a physics competition, but they couldn't afford the trip. They could've just set up a car wash, but instead he set up a tutoring program. So donor's dollar does 3 things: it helps he kid go to the competition; it helps a student who needed the tutoring, it pushes the tutoring student to know the material better and be an educational leader. Why let your dollar only do one thing? 3 birds. 1 dollar.
Follow Up: If donors support a project at the end of the project he spends like $35 on a nice frame and put together a digital collage of pictures of the project and types up a nice letter thanking the donor to go with the pictures. Of course the business ends up hanging it up somewhere in their office, and people see that. He sees this as an investment in future projects.
PR: Every single project he does he gets PR for. A team of students writes press releases and they make t-shirts. Students also meet with donors. But of course he was trying to raise 3 million dollars for his new institute. I'm not sure I need to do that. But I would like to have students write press releases. What a great natural authentic assessment.
Non-Profits Should Have Some Overhead. The backstory here is that he started a non-profit specifically to fund his classes. But I'm applying it to the non-profit I work with, the Vermont Sustainable Heating Initiative. Getting to the point: large-scale donors want to see that you have low overhead, but not NO overhead. The Vermont Sustainable Heating Initiative currently donates ALL of the funds it receives to helping low-income families. He confirmed something I have suspected for a while. We need to stop doing our own books and actually PAY someone else to do that for us.
I'm sure there are probably other things that soaked in, but those are the things I can think of for now. Clearly I have a lot of work to do before school starts! :)

Allan's done this project before in the Galapagos and basically worked miracles there, bolstering education, taking his students to tv stations, and presentations before the UN, and influencing national legislation in Ecuador through a refrigeration replacement program. In his words, he basically "got drafted" by the National Science Foundation to do the same type of work in the United States.
I'm not sure how we were so lucky to connect with this guy, but I'm pretty excited about this for a number of reasons:
(did I mention I love lists?)
1) I love data.
2) I love students taking their own data.
3) I love students taking data relevant to their own lives.
4) I love students taking data relevant to other people's lives and then presenting to them, and making change in the world as a result of their findings.
So good. All these pieces for me add up to a sweet project.
Allan Baer says, there was only one stand-by power study done in the United States on the household level (as opposed to in a lab). And apparently that one study only sampled 10 household. So if even one of my classes does this study we will have a more telling sample size than the most credible study on the topic to date! Very interesting. Super-exciting.

Where are the lucky sites?
1. Hubbard Park
2. The intersection of State & Main streets
3. The College Green at VCFA
4. Montpelier High School
5. Somewhere high up on North Street
These sites represent a variety of elevations and traffic/population densities represented in Montpelier.
Now if we could only get the dang machine to connect to a computer.... :P
(I'm afraid that what I'm actually teaching students is that "real science" requires fancy equipment that mostly doesn't function)

But this hasn't exactly proved sustainable for me on a few levels. It's quite a bit of travel time. It means I don't end up hanging out with the people there very much, so I'm only loosely in community with them. I can't really invite my interested friends to church cause it's such a time commitment. And as any good gardener knows, the proximity of your garden to your front door directly affects its productivity. So being in charge of the "church garden" from 50 minutes away wasn't, perhaps, a great plan.
Of course, I wanted to see St. Andrew's grow into health, and with regular attendance over 40, and our finances starting to become sustainable in the foreseeable future, I feel pretty good about their future. Meanwhile, what blackberry bushes do we have here? I'm sure there are lots of good churches, but I hadn't found one I felt at home at until recently. Well, feeling "at home" may not be quite the right word.
My former youth pastor, Tom Friedrichs, recently took over the Alliance church in Barre as well as continuing to pastor his own church in Orange. Every Sunday he races from the 9am service at Barre Alliance to the 10:30am(?) service at Orange Alliance. Barre Alliance had been in kind of a tough spot, so he called me up to say, "hey come play music for Barre Alliance." So I went, and though it's no St. Andrew's, they are in an unusual and interesting spot where they are highly flexible and open to change - quite a delightful opportunity.
I mean how often do you find a church (particularly in Vermont) who is open to new ideas? Gosh. It's awesome. I mean, fair enough, they were in a tough spot for a long time. Shockingly since Tom took over preaching and I started coordinating the music they've more than doubled their congregation. WHAT? Yes. More than doubled.
St. Andrew's knows that I'm stepping down from my position on the leadership team in March when my term is up. But until then I'll be doing double duty.
So far I've been able to influence the meeting time at Barre Alliance, advocating for discussion questions during church, but how do I influence them to be more green. Granted the culture of this church is significantly different than the hip young progressive culture of Burlington, VT. This is a church where I had a lengthy dialogue about whether or not it was appropriate to have an American flag on the stage. In the same Sunday I had to call out a guy for not recycling (his excuse: "Well, I'm a bachelor". My response: "Do you care about people? Then recycle. Living alone has nothing to do with whether or not you recycle.") as well as calling a different guy out for burning his garbage (me: "dude, that's so not cool. Don't burn your garbage, dude."
So they've got a little further to go. That's ok. I guess I can make a bigger difference here by teaching them how to set up more sustainable systems for themselves. We'll do it as a church at first and hopefully they'll see this as a value at church and thus a value for their day-to-day lives.
In the past my physics students did a study of renewable energy to supply the greenhouse its electrical needs, and so now we have a grid-tied photovoltaic system atop the greenhouse which provides more than the demand of the greenhouse.
And now ... the next layer of awesome: a root cellar!In case you're not familiar with the concept, root cellars are basically natural refrigerators. It turns out that the ground maintains a temperature between 50-55 degrees Farenheit, depending on where you are and how deep you go down, which is already pretty cool, but there's a way to get it to 35-45 degrees, which is more suitable for storing veggies. All that's necessary is having an air inlet (low to the ground) and air outlet (closer to the ceiling). Thus hot air will escape out to the outdoors and denser, cool air will come in through the bottom inlet. Thus keeping your veggies at a nice cold temperature.
But root cellars don't just have to be dug into the side of a hill, they can also simply be a part of one's existing basement. All you need is a window or bulkhead or some other way for air from the outside to come into the space. Enter Montpelier High School.
Of the limiting factors preventing us from growing our own and buying more local food is storage space. With the addition of a root cellar, we could grow more, and buy more food in bulk in season from local farmers to serve our students.
It turns out, that MHS has one bulk head that leads to a space underneath the stage. We've had local root cellar expert, Richard Czaplinski, come down there to check it out and he thinks it will work. The administration is on board and the students are pumped.
Benefits:My students get to use thermodynamics to model the heat flow using equations for equilibrium, insulation R-values, and Q=mC∆T. It's an open-ended problem with no right answer that means something to our community, so it's authentic. Indeed, I do not know what the "right" answer should be. So we'll see what they come up with.
Mold & Asbestos. I spoke with the new facilities guy, Thom Wood, about the potential for mold and asbestos down there. So far the word is that he doesn't think that space was ever tested for asbestos. He and the principal are "pretty sure" it's safe, though I have another friend who is "pretty sure" there's asbestos down there. Hm. So we'll need to get it tested for both Mold and Asbestos by Crothers Environmental. So we'll see what they say.
Permitting. Thom also brought up that it's not technically a "habitable" space, but it probably doesn't need to meet the same codes as, say, a classroom (with natural light and ventilation), because basically it's like a large closet. Thom said he would speak with the fire marshal to figure what we would need to do to make it up to whatever code we need to meet.
*whew* I think it's going to happen. There are some nay-sayers, but I believe them to be under-informed.
My students are presently off and running with the project, we'll have some initial calculations soon I hope! :)
This is my physics class and I meeting with the Principal, Heat Custodian, the Service Learning Coordinator, a local grant writer:
