Ask Slashdot: Classroom Eco-Projects Suited To Alaska?

First time accepted submitter shortyadamk writes "I just started a new job where I will have to visit many high school science classes and have the students participate in 1-3 day projects regarding sustainable energy and environmental sciences (in order to promote the regional universities' programs). I've looked at a number of the boxed projects available online and many of them are solar projects; my biggest issue with that is that we are in rural Alaska and much of the time I'll be visiting classes will be in the winter (when we have very little sunlight — and even if we did it would be too cold to go and play in). I'm curious if anyone has any ideas or suggestions for demonstrations and projects that can be done in the classroom and do not require sunlight. One other catch is that the project has to be small enough to fit in a suitcase or plastic tote; we don't have any roads connecting the villages so I will have to fly the project from school to school with me."

Heat some fresh wood chips in a test tube with a gas burner. Transfer the liquid to a small distiller (the kids already know this one from their dad's shed) and collect the burnable methanole fraction. Use it for a direct methanole fuel cell an charge a RC car.

RingDev (879105) | more than 2 years ago | (#37316480)

It's been a while since I learned about Alaska, but don't they have significant methane trapped in peat moss? That could be a good tie in to the methanole fuel.

Another option would be to get a miniaturized steam engine. People may think they are antiquated, but steam is what generates almost all of the electricity in this country. The heat can come from geo-thermal, nuclear, solar salts, coal, etc... but it all does the same thing: boil water.

Re:To expound on that... (1)

Sleepy (4551) | more than 2 years ago | (#37317712)

While frozen land has plenty of sequestered carbon in the form of methane and peat.. the poster was asking about "eco" projects, which is quite opposite from your answer. You may have as well suggested an eco project based on drilling for oil. :-) Releasing all that trapped methane and carbon is the -last- thing humanity needs (although as the planet warms... it may release all of it anyways... the feedback loop danger that we're ignoring).

Regarding the poster's question, I believe Stirling engines work in extreme cold (if there is warmth at the other end). Also peltier electric cooling is interesting. There is plenty of wind power in cold climates.

There are not very many ecological projects suited to Alaska... fewer still that can be transported by air... which is a pity... I imagine heat pipes buried beneath the permafrost would have excellent utility..

Mod this man up. The (solid) biofuel-oriented nonprofit I started here in VT began in a high school physics classroom. Don't just get the students involved in the science, get them involved in applying the science in the community. Home Thermal energy use (heating and cooling) is a much more accessible field to get budding environmentally minded scientists+engineers started in than the two "sexy" ones (transportation + electricity), but still takes up a similar proportion of the total energy pie, and I suspect even more than the other two given the locale. Biomass (densified or gasified) makes for a great classroom project. Passive cooling also works well in climates like VT and Alaska, but to pull that off requires a much larger scale than works well in a classroom. You could still do something with insulation and learning about R-values though.

Do the boxed solar projects actually require real sun in order to be educational? I mean, would the principles be evident to the students if you shone an electric light at solar panels indoors?

There's an awful lot of sunlight in Alaska during the summer, and the students should have long enough memories to know that.

I think catching the hot air coming out of the entire renewable energy scam would be sufficient. Perhaps burning the now defunct half Billion dollar Solyndra plant scam would warm the hearts of many. They had a fantastic business model. Make solar items that cost 6.00 per unit.....sell them for 3.00 per unit. Make Billions from Government subsidies....heh. But then the Chinese came along and sold them for 1.80 per unit....oops. Massive FAIL. Government then pays Democratic fundraiser the Half Billion back. heh, again.

Now you see the methodology of the Leftist crap shoot of "renewable government subsidies"....not "renewable energy"

Obvious Wind Power or Maybe Thermoelectrics? (4, Interesting)

eldavojohn (898314) | more than 2 years ago | (#37316348)

Obviously you could pack up a small turbine and multimeter and take it outside and show the kids the power generation. You might even contact the Alaskan wind industries [akwindindustries.com] asking for a kit to raise awareness in schools.

Another thought is thermoelectrics via Seebeck and Peltier Effects [wikipedia.org] . I think you can pick up cheap little thermoelectric kits [tellurex.com] that are horribly inefficient (10%?) but if you could coordinate with the school, you might have access to a heat exhaust or something nearby where you could set up the device and show the kids that you can harvest some of the energy coming off the exhausts. Failing that, you could boil a pot of water and position it over it? If it's cold as hell outside, you might even be able to just push it up against a window?

Really, it's just be important to get the kids thinking critically about where energy transfer is lost and how it can be harvested. Most importantly I would stress the efficiency analysis so they realize why your little device isn't the answer to all their problems (but with enough research and knowledge they might find a better solution). You know, give them a little lesson on initial cost versus return and figure out how long it would take your device sitting there at that external temperature for you to fully recoup your cost.

I'm pretty sure if you're a kid in Alaska, you're smart enough to bundle up before you go to school. I grew up in Minnesota and I would have to wait half an hour to an hour for the bus to get to school outside, throwing snow around in pretty darn cold temperatures. We'd put on snowsuits, galoshes and scarves and go outside all day Saturday sledding and throwing snowballs. Fun as hell. There were recesses that were easily 0 to 10 degrees Fahrenheit [wikipedia.org] on a daily basis -- sometimes colder. Anchorage is downright balmy compared to that [alaskaanchorage.net] . Granted Northern Alaska gets colder, it is possible to live outside for several hours if you're suitably dressed.

Inuits and Native Americans did it and I'd wager so can Alaskans.

Re:Grow a Pair (1)

slim (1652) | more than 2 years ago | (#37316794)

Try your snowsuit at -40 degrees. Temperatures where if you chuck a mugful of freshly boiled water in the air, it's frozen before it hits the ground.

Granted, it only gets that low a few times a year in Fairbanks, but I'd personally be trying to stay indoors as much as possible even at, say, 30 below.

I bet the Eskimos (as you're encouraged to call them in Alaska) stay indoors as much as they can in those temperatures. Hunt on dry land in the summer; hunt on the sea ice in spring until it thaws. Store stuff and bed down for winter. (This is based on hazy recollections of a guided tour of Barrow -- in the summer)

Go ahead and treat your kids like porcelain dolls, it's your choice. The reality is that we were outside having fun exercising in extreme temperatures.

Yes, Barrow is colder but given many layers and face protection, you can stand outside for twenty minutes while some guy hooks a multimeter up to a turbine.

Also ask on www.fieldlines.com

That's where a lot of renewable energy people hang out. (Among them is "Wild In Alaska", who built a wind turbine out of a scrap garbage disposal motor to power his pickup camper.)

Obvious choices for Alaska are:
  - Wind power.
  - Thermoelectric on exhaust from wood-burning house heating systems.
  - Heat engines ditto. Sterling or steam. (Note that these are mainly experimental at this point. No commercial systems are available as far as I know for generation from waste heat at less than industrial size instalations.)
  - Diesel generators running on biodiesel fuel (from food production waste) with exhaust heat scavenged for heating.
  - Solar in SUMMER.
All of these - along with related battery storage, control systems, house heating, energy conservation, etc., are discussed extensively on that board.

And most of them are impractical in much of Alaska.

Why are the Alaska schools hosting and promoting this? Alaska is NOT a good site for renewable energy: Extreme cold. Winter storms that can knock down, tear up, or ice up a wind turbine - in an environment where repair work is hazardous. Negligible to zero solar input for months when energy is most needed. Main available energy resources are wood, crude oil, natural gas, and animal fat. The price/performance ratio on virtually all renewable energy systems is even more horrendous there than in the contiguous forty-eight.

This sounds to me like the politically correct school administrators have run amok. Unless it is intended to teach them what they'll find if they move to other states.

I strongly recommend that you ALSO teach them that the current systems are not cost-effective in their area.

Re:also ask on otherpower at fieldlines.com (1)

slim (1652) | more than 2 years ago | (#37316866)

Main available energy resources are wood, crude oil, natural gas, and animal fat.

Of course, efficiently burning wood from properly managed forestry, is green energy. The tree you grow to replace the one you burned, fixes equivalent CO2 to that which you released in the burning.

The same could be said of animal fat, I suppose, depending on the energy sources used in rearing the animal.

Bicycle-powered stuff? (3, Insightful)

bgat (123664) | more than 2 years ago | (#37316360)

I recall seeing somewhere a stationary bike apparatus, e.g. "treadmill", which triatheletes use in the off-season. It's a frame that you put your own bicycle onto, and then pedal away like there is no tomorrow.

The frame I saw folded up into something pretty small and easily portable. I don't know if bicycles are as popular in Alaska as they are in the lower 48, but if so then perhaps a student would volunteer their own for a few days during your presentations.

You'd want to modify the apparatus so that it could be used to power a lamp, or something else that you would likely find at each destination. In fact, purpose-built treadmills-as-power-generators probably exist.

A nice side-effect of such an apparatus is that it tangibly illustrates just how much power even a small lamp consumes, considering how hard students need to pedal to generate the electricity required. You could demonstrate that CFL lights use less electricity by demonstrating that they don't have to pedal as hard to light it, and could show that the excess electricity of the incandescent lamp is converted to heat with a simple non-contact, IR thermometer like those sold at Radio Shack. Then swap the lamp for an X-Box, etc. etc.

Teaching students to use less electricity is an even better goal than teaching them new ways to generate it.

For an elaborate solution, assuming you have internet access from the remote sites... Do a 'Silent Running' type Biosphere somewhere sunny, with robots that can be remotely controlled to perform tasks as needed in this biosphere.

I suggest diving into the synthetic biology movement. Take a look at the BioBricks Foundation [biobricks.org] . Search the Registry of Standard Biological Parts [partsregistry.org] . Maybe there is something missing that you might contribute. Join iGEM [igem.org] , the International Genetically Engineered Machine competition. It is a worldwide synthetic biology competition aimed mostly at undergraduate university and high school students. Some people there are doing amazing eco-friendly projects. And don't be scared by the recent anti-science hysteria. Genetic engineering in general and synthetic biology in particular is not as hard as people tend to think. It doesn't even has to be too serious. For example, in 2006 the MIT team engineered E. coli to produce a wintergreen scent during exponential phase and a banana scent during stationary phase, known as the "banana-fart" bacteria. Some kids are engineering just amazing DNA to produce bacteria that help to digest pollution, or converts sunlight into energy that is easy to use. There is a lot to be done in synthetic biology and both BioBricks and iGEM are directed towards young people who want to experiment and collaborate, without the need to synthesise everything from scratch. You don't need sunlight to do that and you don't need expensive equipment any more. These days people are sending DNA by email and change it like it was just a computer program - which it is in a sense, but it is software that builds hardware. This is truly amazing stuff and I believe this the future of fixing our planet. We have to help mother nature. And this is the most optimal way to do it - from the ground up. iGEM and BioBricks is a great way for young students to dive into it.

Then you might consider a small wind turbine (driven by a fan, of course--no I'm serious, you could use the fan as a prop and explain what happens when you reverse the energy path), and touch on geothermal and tidal power. Tidal power is something you could make your own prop for (just add water on-site and be the wave machine).

Still think the Sun Lamp idea is funniest and quite realistic given the craze to trade food for energy and other such nonsensical ideas.

Uphill challange (5, Interesting)

jellomizer (103300) | more than 2 years ago | (#37316606)

Your problem is actually the countries problem. Green Energy works good in some spots and not all. Solar, Wind, Tidal, Hydroelectric, all have good and bad locations. More portable energy, Coal, Oil, Nuclear. Can be planned for and allocated and distributed anywhere for 24/7 usage, however tends to carry a larger environmental cost (Or just crazy people who fear it blindly like for Nuclear).

I remember in school an important lesson that most people do not get about environmentalism. Everything you do has a trade-off. How many fish die in those Tidal/Hydroelectric power. How many trees will you need to knock down for you Solar/Wind farm and what do do about night/no wind... There isn't any golden ticket for free energy they all come with a cost. Right now we are seeing the Fossil Fuels have been giving off there costs for too long and is making the problem worse.
You should be teaching those kids about trade offs, not some magical future tech that will solve all our problems. Explain how to generate electricity how we use different types of energy. How usually when changing one energy to an other there is often a loss to a different form of energy that isn't useful. How to store energy, batteries, flywheels, springs... Heck show them when you stretch a rubber-band it gets warmer, and if you let it contract it gets cooler.
You need to train kids to be think clearly environmentalism not envionuts and go out wasting more resources to stop all the evils that come up.

Hush. He's supposed to plant anti-capitalistic dreams in these children's heads, not give them actual facts and numbers.

If you show that the most efficient energy source is also the cheapest, then the kids may realize that subsidizing wind farms with tax money depletes our resources more than traditional forms!

The core of the environmental movement today is making Americans to feel guilty for their existence, and then using this guilt to extract money from them. Al Gore has done it by selling carbon credits to guilty feeling Americans. Car manufactures have tricked people to junking cars worth thousands of dollars in order to buy yet another new car that will save them a couple hundred dollars in gas. Farmers have tricked us into burning our food, so that they can sell more of it.

If you really want to do this right, you should sell the kids a book, some carbon credits of your own making, and charge them for your speech. You could also tell them that if they give you enough money, you'll stop flying your plane around, and really save the environment even more. The more ridiculous, the better. If you do it right, these kids will actually learn to evaluate such scams correctly before they get to voting age!

How about a small project to show wind energy? I don't know if you are specifically looking for energy-type projects, but that is one I can think of off the top of my head. If there is no wind, then they can blow on it. There are many tutorials on google and I wouldn't know which would be the best/easiest/cheapest one.

I lived in Alaska for 4 1/2 years starting in 1971. I was very fortunate to have a high school physics teacher that was very interested in real, usable, inexpensive energy conservation projects. We weren't eco-nuts, just kids learning valuable lessons. We covered subjects as wide ranging as berm-housing to geo-thermal to solar energy. As pointed out by jellomizer all had good and bad points but we studied each and tried to understand their impact.

I'd imagine you could create a geothermal power model with a bunsen burner (magma), a round bottom flask (underground water), a glass tube (for rising steam), and a 'turbine' light enough to be spun by the steam. It's likely the only item you'd actually have to bring with you is the turbine.

As for applicability, Alaska has more geothermal land area than any other state (Because it's huge).

Maybe something to do with organic batteries? I don't have any hands on experience, but they do exist, and some don't involve toxic chemistry. I sort of vaguely think there are even some very minor practical applications in some places. At the very least, you should be able to gin up enough power to light an LED or spin a small motor from a kit you can carry in your suitcase. Maybe you can even generate/store power from/in something cobbled together from local materials at the school.

Since the hyper environmentalism is a product of ex-hippies being manipulated by people wanting to use environmentalism to promote worldwide wealth redistribution and hippies always loved being "subversive", why not travel with a hunk of oil shale, a jar of oil sand, a sample of crude oil, a lump of coal and a small cylinder of nature gas and explain to the eager young high school kids that alarmists have been predicting for 70 years that fossil fuels are about to run out and, yet, the predictions have continued to proof false. Discuss with them the political and economic motivations of the alarmists, the role of crisis mongering in obtaining government research grants and tax payer subsidies for non-productive endeavors, the amount of tax dollars which are already devoted to developing new energy sources, the amount of private investment dollars which are already being spent on investigating and developing new energy sources, the fact that most big, government subsidized "renewable energy" projects in the U.S. and in Europe have turned into incredibly wasteful boondoogles which produce little, if any useful energy and are usually shutdown not long after they are completed. Supplement your discussions with written examples of discredited claims of impending extreme climate change disaster and discredited past claims of impending massive, worldwide food and energy shortages and predictions of mass dieoffs of humans. Point out to eager young minds that they have been indoctrinated to wring their hands over environmental issues and that they will be beat-over-the-head if they go to college with the notion that we are all "world citizens" who "share the common heritage" of the "world's resources" and that all of this is propaganda created by people eager to promote a worldwide collectivist empire.

Seriously, your job, as you describe it, really is nothing more than political pre-conditioning for further collegiate indoctrination. Nobody is going to learn much of importance in 3 days of dog-and-pony showing. Learning about "renewable energy" is not the point. Don't stress over what you are going to do. Your job is foster unreasonable concern about the "environment" in the minds of young, gullible minds and to demonize the current means of energy production and the corporations that provide the energy which sustains our society.

Non-engineering projects? (2)

1-3 day projects regarding sustainable energy and environmental sciences

Most/all of the answers have been mostly boxed engineering demos, not actual science projects.

The most obvious science project I can think of is gathering a whole bunch of snow, melting it, and figuring out what is inside it other than H2O.

I have done this, and there is a whole heck of a lot of pollen, and all manner of strange dusts under a microscope. Also just plain ole dirt. And its fun to "core sample" once you've got multiple snowfalls. Its easy to see distinct layers.

I'm thinking your suitcase and budget are not big enough for chemical analysis but a Really good trinocular microscope with video output to a TV is probably realistic. Add some ruled counting slides (forget the proper terminology, sorry) and some buckets / beakers to melt the water, maybe a tiny centrifuge and test tubes to concentrate "whatever"... Get yourself a wide collection of variable pore size filter papers and the chemistry gear to do vacuum filtration thru the various sizes.

Final advice, don't collect the yellow snow.

Whoops forgot the last line. Then take a couple drops of each filtration level and incubate some agar petri dishes and see what if anything grows. Bacteria, molds, possibly nothing. Those cultured plates also look interesting under the microscope.

Sterling engines for power generation, or even simple circulation systems that can be used to heat water for bathing (we filled a canoe with water and rigged a pedal power pump to circulate the water through a coil of copper tubing buried in the coals of a campfire)

The whole idea of packing up a science project and trying to check it into a plane's cargo compartment just won't fly these days. If the scanner at the TSA check[point doesn't understand it, and why would they, they'll simply flag it as a terrorist device and have it destroyed and you detained.

People have had little homemade very harmless devices built into Altoids mint tins taken and themselves detained because all the scanner could identify was a mysterious box with a few loose wires coming out of it. Caused panic in the airport security and shut the airport down for hours while they looked for more of these mysterious little terrorist devices.

Only three real sources of power (0)

Anonymous Coward | more than 2 years ago | (#37317680)

When you are talking sustainable power sources, I'm talking sources for the next million plus years not the next few hundred, there are only three real sources of power. Solar is the primary source since even fossil fuels are stored solar energy and all bio-mass is essentially solar energy that has been stored. Second is moon based which includes tidal power since the Moon is the source of tidal energy. The third is geothermal. It's been said that getting a 100% of all our energy needs for the next thousand years wouldn't reduce the Earth's core temperature one degree so it's a potential long term solution.

Your problem is in Alaska none of it is available readily in the winter months. There's some wind but that's essentially solar it's source is just many miles away. Rivers are either frozen or reduced in volume in the winter since there's no melting so that's not a solution. You have to dig down past the permafrost so geothermal isn't practical or everyone would heat their houses with it in Alaska. Really the only source other than wind in winter has to be stored energy and then you are limited to bio-mass. Most of the practical ones are going to have an eeewwww factor for school kids since they'd be based on animal and human waste. You could show how decaying plant matter produces heat. Let's say you have an insulated box of damp hay or even kitchen scraps. The problem is you need mass to generate a lot of heat. The potential use would be to heat a house in the winter time.

One of my favorites is bio-gas. A little remembered form is wood gas. You can look up wood bio-gas and find plans for making a wood burning gasoline engine. We aren't talking steam or even heat. It's running on gases released from burning wood in a low oxygen environment. If you know a decent mechanic they aren't hard to build. Something like a million cars and tractors were running on it during WWII due to fuel shortages.
