Thermodynamics for Highschool

So, I work at a science center and we have our annual Engineering Olympics coming up and we've been brainstorming something about thermodynamics. The general format is 6 teams from different highschools in the area are given a task to complete from one engineering discipline, such as construct windmill blades to achieve the highest amperage from an attatched motor or insullate a container of water with random materials to prevent it heating up when submerged in boiling water. This year, I haven't really found an idea for thermo that really excites me. Thermo isn't the easiest thing in the world in highschool, and since we're dealing with kids from different schools, we have no way of knowing how advanced they are. So, any ideas of a project to test their thermodynamic mettle?

Help for a highschool project!

Hello everybody, well im a student, and I need your help please as soon as possible!! I have to do a project to finish my last year, I was thinking on making something for deaf, like a game or something to teach them how to read, because I've read that most deaf child don't know how to read and it is all because they're parents.. This last year a group win the science fair making a wheelchair that is commanded by the voice, now they are in LA showing that... Or anything else to do!! anything helps! thanks a lot... by the way, im from Uruguay. Thanks!

Integrating Highschool Sciences

Irene Duke, Kate Hoff, Lyndsay Carlisle and myself are participating in the MIT course 11.124, _Introduction to Teaching and Learning Science and Mathematics_. We have a variety of teaching interests: Irene hopes to teach chemistry, Kate to teach Physics, myself Physics or Mathematics and Lyndsay hopes to teach social justice / political history. Provided Make magazines as inspiration, we were tasked to design a joint activity, merging four high school classes of these topics for a period of weeks or months. We developed the ideas described in this first entry over the course of a class period. Hopefully, we'll take the time to expand each step into an instructable, possibly including trials by fire teaching 8th-11th graders. The material is structured by conservation of energy and resources, inspired by the articles of Tim Andersen. The final demonstration we envision motivates the particular material we wanted from each field. A bicycle wheel is drives an alternator transforming mechanical energy into electrical. The electrical energy is used to run a electrolysis process, rendering separate measurable quantities of Hydrogen and Oxygen. The Hydrogen and Oxygen are then combusted for the students. The amount of mechanical energy can be measured, as can the electrical. The binding energy of H_2O can be used to determine the chemical potential energy rendered. Finally, the combustion both demonstrates the energy's new form, and the difficulties in storing energy. The difference between power and energy underlies all of these experiments. Conservation of linear momentumn should be a familiar topic with the students. Conservation of angular momentumn can easily be introduced at this point, demonstrated with the bicycle and a fly wheel. Chaning the orientation of the wheel can be exteremely difficult. For the chemical portion of the experiment, stoicheometry should be familiar to establish the link between the amount of gas generated and the energy invested. The most appropriate mathemetical tools are statistical. Sampling, linear regression and averaging would prove useful throughout the experiments. Global economic relationships leading up from the colonial period would perhaps be the most applicable topic form history or the social sciences. Though not a technical detail, an important aspect of executing such an idea involves the actual deployment of resources. Students could, for example be broken up by their topic of interest, whether it be the physical, chemical or social aspects of the project. Next, new groups would be formed with one or two members from each subject area. These groups could then attempt to execute the design from the first slide, or one which is similar. Throughout, the students will present their thoughts or understanding to the teacher. This design project should perhaps be phrased as simply turning mechanical energy into hydrogen. Students with social scientific background might be responsible for estimating the costs of the implementation in different settings, and that would be used to drive a larger scale version. So, before getting started on building and documenting this project, do people have suggestions? What worked to combine the physical sciences for you? What might have worked?

National Science Bowl teams used my Trebuchet for a competition

I received an awesome comment. A high school teacher used the plans for my Quick'n'Dirty Trebuchet as a lunchtime competition project for teams competing in the National Science Bowl. The teacher made up kits of the parts: masking tape, dowels (I used chopsticks), paperclips, toothpicks, string, a binder clip and a weight. The teams then had to assemble it and held a throwing competition. The winner averaged over 20'.This is why I make Instructables, and most specifically why I made this one. I wanted it to be easy and cheap, no special hard to find parts, work well, while still being a real Trebuchet. I loved the comment.Here it is:My school hosts a regional competition for the National Science Bowl for high school students every year with the winner going on to the national competition in Washington, DC. This year I was in charge of finding some sort of competitive project for the teams to build and compete with during the lunch break. I chose your quick and dirty trebuchet and made a kit for each team. I made a few changes to your plans. I used 12" long 1/4" cut dowels instead of chopsticks since I didn't have a cheap source of chopsticks. I did not give them rubber bands and instead they were to tape the paperclips on for the axle. They were given a 200 g weight with a loop of string taped to it for the weight. The projectile was a mini binder clip with a loop of string tied to it. The complete kit contained the 9 dowels, a roll of masking tape, 4 paper clips, the 200g weight with loop of string attached, mini binder clip with loop of string attached, your printed instructions as a guide and a sheet explaining the rules of the competition.It worked out quite well. The teams were given a copy of your plans as a guide and 20 minutes to build their device. The competition was they were to launch the projectile three times and it had to land inside a track 4 foot wide each time. The distances of the two best of the three throws were added together for their score with a foul (outside the lines) counting as zero distance. We had 12 teams participate and the winner had a score of about 44.5 feet. They all had fun and I think learned something too.

How I Learned to Stop Worrying and NEVER shop at RadioShack

So, tips for building things that I've learned today:Have some strange piece of hardware that you're trying to take apart? Like that dead cell phone, for its pager motor? I just found the bristlebot project, and it's too cute. Also, I'm home for winter, and all that Highschool-Star left here was a pile of magnet wire, and some electrical tape. Not even a breadboard! (Ah well, thanks highschool-Star, for what stuff is here - Star-of-the-future gets none!).So, without a tiny Torx-6 screwdriver that I'm sure my family would use exactly once (I mean, that I would use exactly once), I drove to the nearest place and - did not buy one.I walked in, unscrewed the screws I needed out, and put it back on the shelf.$15, saved!Also, don't buy batteries at radioshack, ever. 3V coin-cells were the same price as 1.5-volters, and, at $6, all of them cost less than a frappucino at Starbucks. Six dollars! That's around $2 per VOLT, at best! So I left and went to the drugstore where two 3V coincells cost $2. Much better.

How to display dvd player chapter and timestamp info in two separate locations and not on the projection screen?

This is for a highschool orchestra to rehearse and perform during a silent film presentation. The person projecting the movie needs to monitor the chapter and timestamp and so does the conductor of the orchestra some distance away and preferably with a larger counter display (like this one). I've looked into extracting a timestamp signal from any player outputs but this seems to be absent except maybe in the audio output. Also, if there were a way to hack into a OS X dvd player to output the control information (specifically the timestamp) we could use a macbook too. Only thought I had was to get two identical players and take the LED display panel out of the second and somehow wire up to the first. Thanks for any thoughts you can share!

Magnetic accelerator coil Answered

Im going to try to keep this short. So a friend and I are both sophomores at our highschool and we are both in chemistry (which is a higher level science) and i built a coilgun for last years project and attempted to build a PWM driven one this year. My friend and I want to build a rather large coilgun using either 10 microwave oven caps or close to 40 or 50 caps from computer power supplies. What i need help on is whether we should use the microwave caps which are high voltage but low capacitance or the power supply caps which are 200 volts and around 500 micro farads. I also need help on what wire to use for my coil and how many turns for the coil. i would like help with a coil for each cap size.

10-15 AMPs w/ potentiometer.

So, as a chemist I thought it would be fun to save some $ by making my own hot plate & magnetic stirrer. I am using Thermoelectric cooling device (TEC) to heat my stirrer, and a small DC motor to stir. Here's the problem - if you've ever taken highschool chemistry you will know that a hot plate with a stirrer has a potentiometer for Temp & Stirring speed - I'd like to do the same! Problem: the TEC takes anywhere from 5-20 amps in operation @ 12 volts DC. Adding a potetiometer to this in parallel is out of the question - I can't fine a potentiometer that can handle greater than 2 watts. ( i may just be looking in the wrong place)... So.. all in all I'm looking for nearly 140-170 watts of power for my heating plate. (The motor will be using much less, almost negligble to the heating plate) So, if I can't put a potentiometer in series for power regulation, how can I get my temperature to vary? If this is going to require a circuit board, I may need some help with a design :)

Every year NASA has a competition where schools, colleges, and universities throughout the world create moonbuggys and compete on a "moon course" in Huntsville Alabama for the fastest time (if the moon buggy even makes it across the terrain) Anyway, while I was in the competition there was a special event where you can have pizza with the "pioneers" (the archaic dudes that actually made the moonbuggy). It was an offer that I couldn't reject! So, I attended the secret meeting and we got to ask the "pioneers" questions. My question basically was: "If you had today's technology, what would you change about the moonbuggy?" I was looking for an answer that describes a superconducting hovercraft, but they instead talked about changing the radiator (lol, well it an awesome experience either way). What I didn't know was that my question was nominated for the "best question award" and they sent me a lunar rover book signed by the pioneers ( “Sonny” Morea, the project manager of all the space procedures at the time signed it. I don't know if it means anything to anyone these days, but it means somethin' to me!) Thats all. Thanks guys!

HELP to make a hanging cluster of LEDs. I would like the LEDs in groups and one group at a time fading in and out.

Hi Everyone, I am new to Electronics (well I did the basic electronic circuits in Highschool but that was many moons ago!) and am needing some advice.  I am wanting to set up a hanging cluster of approx 300 LED lights.  Each LED will be hanging off its own individual wiring.  In the cluster there will be certain lights creating groups.  I would like all LEDS to come on at the start and then fade out. Then one group at a time to fade in and fade out. I have attached a VERY BASIC colour-coded drawing to show what I mean by the cluster and the groups. I am wanting to use LEDS that are smaller that 1cm in diameter.  I would like the warm white look instead of the cool blue white and each LEDs need to be quite bright.  I like the look of the Dome LEDS but am open to suggestions!  This set up would need to be battery powder. I have been trying to research how to set it up but am a bit lost.  I am stubborn and driven so my lack of experience will not stand in my way.  Any help, advice or pointing in the right direction would be awesome.

Bringing old LCD screens back to life

When it comes to school projects, I always use my electrical knowledge to engineer some sort of out-of-the-box project. Being a freshman in highschool, most people are sort of amazed by my works. It's all basic stuff, really. I've been doing a lot of work with :EDs inside of these homemade posterboard boxes I've been making. After making one for each class, they're getting really old and they aren't too great looking. So I'd like to really give people a show. About two months ago, I got a 12 inch LCD screen from an old Compaq laptop. For reference, the screen (on the back casing) reads, "LCD MODULE AL LM-JK53-22NTR 10D40092527904". I cannot find many references to a pin-layout or a datasheet, but that's not too much of a problem. If it comes down to it, I will test each pin until I can get some progress. I am interested in using the screen to display data. I don't mind if colors aren't present other then black and white. Black and white works for my purposes. Is it possible to use this with an Arduino? With my initial research, I found that using a VGA card with a VESA Feature Connector will enable me to get the job done. I then run into two problems: 1) I cannot find one of these connectors, and 2) I am unsure if I could even make this work with an Arduino Uno. Any help is appreciated. If the project isn't possible, it's not the end of the world for me. By senior year, I probably will have built a full computer anyway :P ~Joe B.

I gots a computer question

Hey guys, I got a bit of a question to ask. I'm back at school and the school gave me a laptop to use (I'm in highschool) but it's one that doesn't have "their" school modified disk image on it with their crap like deepfreeze (resets the entire system each reboot) and of course, pretty much everything is cut out of the start menu and it's just generally shit (hence why I had removed the image and installed my own XP on it). Long story short, the tech teacher I was talking with said that (well actually he kept switching his story around) he had the wifi key written down somewhere but couldn't remember where he put it (suuurree). Then he told me a schoolboard admin was coming thursday (this past thurs) and the guy would set it up on my laptop for me. He did come but he never did anything for me, him and the teacher spent all day playing with some new photocopier they got. So yesturday I went on one of THEIR laptops (ironically it was said teacher's laptop he used in the school cept he wasn't there so I was able to use it). I went looking through the computer for where the wifi utility that both I and the school use for managing connection profiles and their keys instead of letting xp handle the wifi. Standard ibm software I got of their site. It appears that the keys are stored in the regristry and not in files, they're listed in folders for each profile. So what I did was save the directory of profiles (there was only one for the wifi). Now it looked like they were hex keys, and I'm pretty sure it is HEX but it's longer than what will fit in the settings for wifi in the ibm program. So I was wondering if the numbers are hashed or something so you have to crack the codes to access the actual hex key? If anyone knows how I can get the key out of the number I can send you the .reg file that I saved. I'm not trying to hack into the school, they know that I need access to it so I can print my work out but the tech teacher seems to be a dumbass (not to mention he looks like captain picard/mr.clean, a combo of both maybe?!!??!).

Look back over everything I posted, I'm a bit tempted to go back over my old instructables and fix up all the errors in them and such, and if I find time I might seriously consider doing that. Because ofcourse when i was ~14 I didn't really notice but some of those Instructables are a bit ugly. I'm a bit hesitent to just go and fix them up though. I think they may best be left the way they are, with all their numerious spelling and grammar mistakes, considering how long it's been now. I also went and updated 'The Christians' group (First update in 4 years, woot!). I'm sure those other 87 members will be very glad lol, honestly I don't know if it's gained or lost members since I've been gone. I'd personally guess lost simply because it would probably be somewhat hard for anybody to find the group at this point (You'd have to search for the exact name, find it, and then join) and some of the old members might not even be on here anymore. Not really sure, but it needed an update anyway. Most importantly though, I really wanted to thank everyone here at instructables that was here and talked to me and such back when I was still K'Nexing. I was ~14 at the time, could barely type (Infact, Instructables taught me how to type, When I joined Instructables I had almost no typing skills at all). Everyone here was kind, didn't hold grudges or get mad at me even though I was obvioiusly a little kid, younger them most of the regulars on here, and my typing skills and grammar were definitly not up to par. Reguarless, I really found a nice athmosphere here, and I'm very lucky I did. I was never a very social kid (The fact that I had, something like the 4 most comments out of every member on instructables one of the years I was here should be evidence of that.) and I'm still really not that sociable. I really don't know what I would have done with myself if it wasn't for me being on instructables. Instructables literally shaped my life, and I'd go as far as credit Instructables as the reason why I'm now going into Computer Science and Engineering in college. It's all because one day I went through an Instructable on Windows Batch coding, and that led me to take a BASIC computer programming class at my highschool, and now here I am ~4 years later going into CSE with a full tuition scholarship. Honestly I wish there was more I could say, but really all there is to say is that Instructables really effected me at a key point in my life and really if it wasn't for Instructables chances are I wouldn't be where I am now. On another note... Where'd all the orange go? All this white is hurting my eyes :P DSMan195276

I need some expert mac help!!

Okay, I got a bit of a story, and a bit of a question (Las Vegas, I know you can help me). I've been transfered to a new highschool (not that new to me, I've been to it before) and I've been there for about 3 weeks now. I was given a thinkpad R51 by the school board while I was out of school to use for school work and to take to school. That's all fine and dandy, but the restrictions on their disc image are unbelievable and it makes it next to useless to me other than a gigantic calculator with a shitty battery life. So I wiped it of course, repartitioned it with a 30 and 10 gig partition (respectivly both NTFS, the backup partition, the 10 gig one, is currently in fat32 as I forgot macs can't write to NTFS). So everything works fine, when I got transfered to the school, I asked the so-called "head" techy teacher person of my school for the wep key for the wireless network in my school so I can print my work out in class instead of waiting till I got home (teachers don't like that sometimes). Since I've been to school he's made up excuses like "I know I have the wep key wrote down somewhere, but I know it'll take me like an hour to find it so I can't right now - I've been told that on 4 different occasions on 4 different days. Funny thing is that both he and I know that their wireless isn't actually pure wep mode. It's a wpa enterprise mode of some sort with a required username/password combination to log into it (that's fine though, it'll still work if I have the password). Oh yeah I forgot how I took my ibook to school one day, then the next day (no not the day I was showing him my ibook) he tells me that the wireless will work on my ibook, but not the thinkpad, which, like every other fucking laptop in the school, is a model R51 type 1829 with the odd old R40 laying around. It's excuses after excuses, my mother wanted to call in and give them hell for leading me around but I told her no, I'm curious to see how dumb this teacher thinks I am (and so far I've been playing dumb). NOW he tells me that I need to now, re-image my thinkpad with their school disc image they use on their machines, which I don't have to agree to doing because the laptop didn't come from this school and so it's not theirs. There was absolutely no reason it would not work as I even used the exact same wifi drivers/software and even the same profile management software they use on theirs. Now, I'm almost done but let me explain the last bit of why I'm even posting this lenghty (and possibly waste of time) post. I recently re-reformated as somehow I contracted a nasty trojan downloader onto it, and it was due for a clean up anyways. Well wasn't that a rough ride, since the reinstall I've had to wrestle a video driver onto it, fiddle around with all the other drivers to get them installed, and I still can't get a wifi driver to install. Even if I force install one from the "manual" option when XP asks for drivers (yes XP does have generic Intel Wifi lan drivers for my card) and it wouldn't go, just gave me an error 10 code (device cannot startup). Okay, so the driver isn't compatible? Well Lenovo only has 3 different wifi driver packages for different wifi internal cards for my "one" model/type of laptop (the type "1829" is lenovo's numbering system basically for revisions, and when I went on their site for drivers, it askes me for this, model, and a specific 3 digit number on the bottom (order code I think). So why it can't just tell me the specific card in my revision (as I'm sure there's probably only one card for my revision) is beyond me. I downloaded all three, the first two were just small driver/utility packages (I think they were only 802b drivers too, at least one of them was). When I tried to install them, no luck, first appeared to install it, although the drivers never installed apparently. So I uninstalled what (still) there, and tried the second, same thing, except nothing installed, but it appeared to install. So I went on to the last one, it appeared to be succesful. Not, for some reason, windows could list me all the ap's around here, but couldn't connect to them, or mine, and I know I put the right key in. And when I tried to use Ibm's utilites to connect, it kept crashing, and it was even crashing the wireless zero config windows service thing every time I tried to power on the wifi or such. However I don't even care about windows right now at this particular time or fixing the drivers, for all I know there was a scratch on the install cd and it's botched (very unlikely as I know the install would halt and say it can't read) Now because my teacher has been literally screwing around with me (I'm not assuming here that he's lying to me and making excuses, I know he is because it's just too obvious, you guys tell me). Plan? Install mac os x on the thinkpad and ask him again if it'll work and if he says no, I will probably rip him a new asshole right there on the spot, seeing as he's told me multiple times it will work on my mac, but not the thinkpad, so if I have mac software on there, shouldn't be a problem (hehe). I really want to do this to get back at my teacher because he doesn't believe anything I tell him and he thinks he's pretty smart, just generally another guy with a too-big ego for one person to handle. I downloaded the iAtkos disc image as directed by instructions I found through google (yes, torrent, illegal, don't harp on me for it, jobs makes enough as it is with ipod sales). It's supposed to be pre-patched, and also supposed to include additional driver packages of some kind (that's a plus). And to boot, it's supposed to boot off the dvd (lawl) without any tricks (like usb drives and that smutz). It all seems pretty sweet, and it did boot when I popped it in, but It went to the mac loading screen (the white one with the grey spiny thing) and just sits there with absolutely no activity. I booted it with the -v/-s command(s) and this is what comes up when it stops loading and sits: "Extension "" has immediate dependencies on both and components; use only one style." My understanding is that the plist file might be missing some components the driver is calling for, but the "use only one style" part doesn't make sense so I know it's something else. Although it didn't say, I presume the kernal was already patched as it was supposed to be a pure pop-in-and-go image. I was hoping to try installing the EFI patch after too if I can get it going in the first place. And yes, I did quite a bit of googleing before I came to here. I could find information on R40's with mac os x installed on them (or was it x40?, I know those are newer, the r40's are old) and other models inbetween but nothing on thinkpad. I don't even care if it's fast or works 100%, I just want to do it, I do also know that the atheros chipset in my wifi card is native compatible with tiger apparently and should show up as a standard airport card. I don't know if I'll be amazed or not when I post this finally and see how many pages long it is, but I do really need a hand, because this will be the final step before I go to the VP and tell him that this guy has been screwing around with me and blowing me off. I deserve and education dammit!
