Ok... So we are starting electricity unit in science (I'm in 9th grade advance placement physical science) and on the first day the teacher give us a battery, a lamp, and a 1 wire. We had to light the lamp up... And nobody could do it except my freind Tim and me. Nobody could even figure out that a lamp has 2 terminals and that both have to be connected for it to light up. What do you all think of this situation.

It's better than giving them a battery, a resistor, and an led

A required freshman class at my school was "set" or science engineering and tech. It's like this all over, trust me. But there's not much to comment on. A lot of people(adults even) only know how to swap out batteries. It's why electricians get paid as much as they do. I started working with mains in around 7th grade, and general electricity a while before. I don't need to hire an electrician because it's just so easy compared to the level of e.e. that we do around here!

"1 terminals, and both of them need connected"?
I'm disgusted by your lack of math/proofreading skill

Nor am I surprised that most of the kids didn't know how to wire up a simple circuit with a battery and light bulb. I remember being the only one in my high school physics class who could wire a plug.

And more recently as a lab demonstrator, I had some really bad experiences with 1st year engineering students and solderless breadboards.

To sum up, you guys are all abnormally clever or lucky or both. Even if you can't count the terminals on a light bulb yet, but with practice the math skills will come

I'm studying Power Engineering and I was surprised to see the first few courses contained mostly just staring blankly at a DMM. "Look at it, but no touching yet!" Then we advanced to making LEDs explode. Fun.

Yeah, the courses got a lot more advanced quick, but it was still a shock. And I'm still the only one in my class who tinkers with electronics in spare time, which was another surprise.

Oh my god thanks finding my error!
My teacher does want me to run my vttc for the class!

ROFL been there done that. I remember when that happened in my class over the summer. I got it to work two seconds after they gave the materials to us (literally) the others took ten minutes. Luckily this year in high school they offer an electronics class. I'm so happy I'm not the only 9th grader on here! Phew. lol in my electonics class, we build circuits. however, he (the teacher) never explains to us how they work. He also gives pictoral diagrams which you can barely see, which I call "scime-tics". anyways in class, bell just rang. I'll type more later. bye!

EDIT: I'm the only girl in my electronics class. Heck, I'm one of the few girls on this forum. In my class, I'm the only one that is really passionate about the subject. I'm the one where when people are missing 10 wires/parts, connected 5 things backwards, and 20 things are in the wrong holes in their circuit, they come to. "I checked it a million times, I know everything is connected right! Fix it!"

Reminds me of when I brought in a jacobs ladder and a guy had an RC car with him. He thought if he hooked up the battery to the terminals it would make a better arc.
Good job I had an enclosure as people kept trying to touch it as well :/

It's alright. Most Harvard medical doctors cannot solve the same problem.

Oh god don't remind me. What's worse than students not knowing how to wire a light-bulb correctly? When a teacher can't even figure it out. Seriously. I have taken several classes that have dealt with electricity in high school, the first, a physics class had a unit on electricity and magnetism and I knew a lot more than the teacher (she couldn't understand why buildings weren't powered by DC instead of AC). I ended up teaching the class about parallel and series circuits (she still refers students to me when they need extra help). Then this year, I took a Project Lead the way class and there was a week we spent on electricity and breadboards. I taught the whole week including how to properly use a multimeter. The other thing that annoys me are teachers who are ignorant about electricity, for example we had a mains introduction and were supposed to wire up a couple lights using alligator clips and on the kit it said the max current draw was 800mA. It had a 35 amp fuse.

EDIT: Sorry for the rant
