What To Cover In a Short "DIY Tech" Course?

edumacator writes "Our school is working hard to provide our students with relevant opportunities of study. We have a short 'seminar' period that meets three days a week for thirty minutes. I've chosen to teach a seminar on 'Home Grown Technology' even though I'm an English teacher and only an amateur techie. If you had thirty minutes, three days a week, for nine weeks, what would you teach a group of high school students? I'm considering the Wii-mote smartboard and multitouch displays, but I'm afraid I'm overreaching."

Teach them something useful

Not necessarily overreaching (I guess it depends on their prior experience), but those projects, while they have a definite "cool" factor, aren't particularly useful.

Personally I would stick to teaching them more useful stuff... maybe basic repair of electric appliances, or if you want something more advanced and that has both the cool factor and would be useful (at least to some people), maybe this DIY book scanner.

Pyrolysis of biomass.

Pyrolysis of wood or other biomass such as garbage into carbon monoxide and hydrogen gas for use as a fuel for vehicles or cooking.

Teach 'em something useful

[Capt.DrumkenBum]

Like clicking on a link in an unsolicited email is a BAD idea.
I took a course in 10th grade, it was some simple electricity course, Electrical safety, series and parallel circuits. resistors and capacitors. The final project was to build a simple electric motor. Including winding the armature and coil by hand.

I found this course much more useful in real life than just about anything else I have ever learned.

I was going to put a vote in for some kind of electronics project as well. I am finding that more and more of my friends (college age +) who have great DIY spirits (car and motorcycle tinkering, learning computers in depth, even sewing) look at electronics as some sort of black box of magic that they can't/shouldn't tamper with. My own roomate was looking for a pair of LED blinkers to install on his motorcycle, when I recommended he make some himself using bought/scavenged materials he got nervous at first. When I started drawing some circuit diagrams for him and told him I would help he got excited.

My point is, electricity, in and of itself, is nothing to be feared/worshiped if properly understood. Teaching kids to hack away at some electronics could greatly improve their understanding of some of the most common items we use everyday.

As for a suggestion, I would tell you to have each of them go home and get their parents/grandparents to donate an old walkman to them for a project. Then have them disassemble it and use the components to make some kind of mobile toy (hence using something with a motor) that they can take home and show off. Of course, this requires soldering, but it still could be great fun for them. I personally have built two Symets (little bouncy pseudo robot things) from old Discman's and had a great time doing it.

That's my two cents.

I did something similar with 8th graders

[EMB Numbers]

I did something similar with 8th graders. Use short physical projects to keep them engaged. Have each student build a tower out of a single sheet of copier paper and tape. The tallest free standing tower wins. Build boats out of measured amounts of aluminum foil. The boat that holds the most marbles before sinking wins. Build water rockets out if 1L plastic bottles. Build bridges out of tooth picks, paper, and glue. The bridge that holds the most weight before failing wins.

Each of the projects can be completed in 2-3 half hour sessions with almost no material cost. These projects teach basic physics and engineering in a fun and competitive way. You can even repeat the same projects later in the term so that the second rounds of towers are designed with knowledge gained in the first round, etc.

Boooring!
show the kids how to build a PotatoGun (tm).
That should keep them interrested
