April 2012 Science Discussion

<p>Ozone is protection from UV radiation. More UV hitting surface means less hitting ozone, which is less ozone. And if UV creates ozone, UV would be creating the least ozone when it was hitting the surface the most -> still the least ozone</p>

<p>For the passage without any charts or graphs…were there any A’s…i put all A’s down for it!</p>

<p>what about in the ozone passage when it asked would it be more likely to be 4-5 or 5-6</p>

<p>Less ozone = more UV radiation and vice versa
Student 4 was correct for the one question about mass staying constant (he/she said that the liquid decomposed, but didn’t evaporate)</p>

<p>There was a lot more reading on the science that I thought there was going to be.</p>

<p>The last question on the conflicting viewpoints passage was like “if a colorless solid was put into the mixture and the thing turns green, whose hypothesis is supported?” Does anyone remember what they got for that?</p>

<p>@sky i think the question said a colorless solvent</p>

<p>Yeah, it was something like that. But do you remember the answer? I’m trying to gauge how much I failed hahaha</p>

<p>what was the last answer</p>

<p>If it was colorless solvent, then it would’ve been student 2.
The scenario in the question was given the white solid left in the container, we pour a colorless solvent in. Student 2’s hypothesis involved a colorless solvent, white solute changing color b/c of a SSC</p>

<p>@skylimits I think I put 2. I struggled with that one. Do you remember the November, October and some other month chart passage well?</p>

<p>Did you guys think this test was easier then the past ones? What do you think the curve will be?</p>

<p>Do you guys remember the question about independent/dependent variable? What was the answer and why? </p>

<p>Also, for the conflicting viewpoint passage, was one of the answers Student 1 and Student 4? I think it was for the question that had a quote about creating a green solution or something like that…</p>

<p>I would also like to know what everyone’s thoughts were on the dependent/independent variable question. I believe it involved the RH…</p>

<p>RH was dependent, as it was measured.</p>

<p>That was my thought. Just wasn’t sure if the RH was manipulated directly or not, didn’t really read the passage.</p>

<p>The science was weird because I felt really bad about it as I was taking it but in retrospect I believe I did quite well.</p>

<p>@pr0 i said the same. we are right im confident</p>

<p>Wasn’t the number like it was measures by scientist? What number was that question?</p>

<p>Did they use the drying agent to remove H20 from the container?</p>

<p>Yes. They needed to remove H2O so that they could measure the RH of the chemicals themselves.</p>

<p>@Cant What was the question and answer?</p>
