Science quiz linktarding
 

OK, mods, feel free to lock if this is linktarding, but I think this might be fun enough to pass the OOT bar.

I got a B, 84%.

Edit: Ones I got wrong - 2, 9 (stupid, misread q), 15, 16

Re: Science quiz linktarding
 

96, A. Missed the one about meteors and the one about aerobic/anaerobic respiration.

Re: Science quiz linktarding
 

bob,

If you missed two, you should have gotten a 92!

Re: Science quiz linktarding
 

77, misread 2 questions due to laziness.

Re: Science quiz linktarding
 

I'm halfway though and I just want to say that this is the hardest 8th grade class in the history of the world! Also I'm pretty sure the last time I took an earth sciences or astronomy class was in 8th grade, I feel like I'd do better if there were more easy Chemistry questions.

good thing it wasn't a math test! Those were the two were it looked like the bar didn't move, but maybe I'm bad at watching bars as well as at division.

Re: Science quiz linktarding
 

B- with 80%....I feel stupid.

Re: Science quiz linktarding
 

84 for me as well. had some lucky guesses in there

Re: Science quiz linktarding
 

Missed 2, 7, 19.

Re: Science quiz linktarding
 

88

oh... my... god...

I GOT A D+, I'M GONNA GRADUATE!

Re: Science quiz linktarding
 

88% missed #2 (although i was thinking metamorphic when i clicked igneous) then missed meteoroid and aerobic & anaerobic.

Re: Science quiz linktarding
 

Your Grade: A-
92% You Passed with an Excellent Score!

doesn't feel excellent.

Re: Science quiz linktarding
 

I hated Earth Sci, Bio and Chem this test sucks D+ pretty much the grades I got in those classes too when I went.

Find like a physics one or something or electronic circuitry [img]/images/graemlins/smile.gif[/img]

Re: Science quiz linktarding
 

73%

Re: Science quiz linktarding
 

57% and I guessed on several=(

Re: Science quiz linktarding
 

73% and I was a math/science wiz in school. [img]/images/graemlins/wink.gif[/img] Of course, that was a quarter of a century ago.

Re: Science quiz linktarding
 

I missed one, the velocity question. I thought it was a trick question, so I went with 0. Doh.

Re: Science quiz linktarding
 

76%, and looking back - we took a lot of [censored] retarded stuff in elementary school

Re: Science quiz linktarding
 

I bombed, 70ish with little certainty

Re: Science quiz linktarding
 

100

Re: Science quiz linktarding
 

I got 96%. The one I got 'wrong' was the question on the purpose of fruit; actually the question is screwed up there. The purpose of the fruit is not to protect the seeds, it's to attract animals to eat the fruit, providing nutrients to the seed after the fruit has been digested.

Some of the others were screwed up but I managed to work out what answer they wanted.

On the whole I really, really hated this test. This isn't really anything to do with science, it's just a list of random questions. There's no real education here and I can understand why kids think science is bring and stupid if this is how they're exposed to it.

Re: Science quiz linktarding
 

Are you smarter than an 8th grader at science?

I think you may have a new spinoff show here!

Re: Science quiz linktarding
 

73

Re: Science quiz linktarding
 

Also, fwiw, I don't think I was taught a large percentage of those answers...and I was in advanced classes, how useless

Re: Science quiz linktarding
 

what's with the answer to that "final velocity" question?


it seemed kind of like a trick question, final velocity should be zero right, since it comes to a stop after being dropped? i can't remember the wording but i remember thinking 100 m/s or 0 could be the answer depending on interpretation.

Also, "This type of rock is buried deep within the earth's crust" couldn't that question be legitimately answered igneous or metamorphic?

Re: Science quiz linktarding
 

missed 7 9 and 26

Re: Science quiz linktarding
 

Too many "facts", too few "concepts". 84%.

Edit: upon further review, I retract that statement. I'm just bitter about the ones I missed.

Re: Science quiz linktarding
 

I missed the one about chemical change, but got the rest right.

Re: Science quiz linktarding
 

88% - 7, 11, 25

Re: Science quiz linktarding
 

65%. Woot.

Re: Science quiz linktarding
 

I am a scientist.

I missed the one about meteors. I actually never even knew the difference - you learn something new every day, I suppose.

I also had to take an educated guess about the types of rocks, but was about 65% sure of the correct answer and got it right.

it said what is the velocity as it hits the water, right? there's nothing tricky about that question.

actually it doesn't say that


"A stone dropped from a helicopter takes 10 seconds to hit the sea below. What is its final velocity? (Assume that the acceleration due to gravity is 10 m/s2)"

seems ambiguous to me. actually, since it uses the word final i am much more inclined to think it is asking about its resting velocity. the only thing that makes me think twice is the fact that is would be a pretty trivial question if that were true.

Re: Science quiz linktarding
 

Maybe at some point in the stones life, it is launched into space, where it becomes a meteor/meteorite/comet, whichever term is correct, and thus has no "final" velocity?

ZOMG you blew my mind

Re: Science quiz linktarding
 

"resting velocity" LOL

i think it's painfully obvious that the question is asking for velocity upon impact with the water. otherwise why would it even say it takes 10 seconds to hit the sea below? the whole question is talking about the ball hitting the sea, then it asks for a velocity.. seems open and shut to me that they want the velocity at impact. i mean do we really need to specify what reference frame we're talking about in this question, or is it just implied that we're in the frame of the earth? otherwise you could just extend ANY problem infinitely into the future and say dumb [censored] like

"well who knows what's going to happen to the ball a million years from now! also it's on the earth and the earth is spinning around and flying around the sun, so it's moving pretty fast lol!!"

Re: Science quiz linktarding
 

Got the one about plants losing water to the atmosphere wrong [img]/images/graemlins/mad.gif[/img]

sorry if it seems nitty, but guess i am used to working on well defined problems. i guess its normal in physics (at the introductory level at least) to assume away a lot of factors, even if they aren't always stated.

i automatically answered 0 without a second thought. i wasn't trying to be clever or overly-analytical, it wasn't until after the test that it occurred to me that it could be interpreted otherwise.
