<p>This thread is great.</p>
<p>Prideful & Water + Air for me. How could a mesh bag trap CO2?</p>
<p>Prideful: 28
Reliant: 5</p>
<p>Mass:5
Water/air:22</p>
<p>i dont really remember why i had choose water/air. i think it was because i figured they wouldnt have wanted it to effect the results or anything. basically, i just made a guess lol</p>
<p>The mesh bag seems right. Think about a bag, a mesh bag with tiny little holes. What does it remind you of? To me, it brings thoughts of colanders, or pasta strainers. What do those do? They allow excess water to pour through the holes in the bottom, and don’t allow the larger mass of pasta to get out. That was my logic, paired with somewhat intelligent guesswork.</p>
<p>omg *** does water and air have to do with anything? they were measuring to see how much mass decomposed. so therefore mass would need to be able to leave the bag</p>
<p>that part just said</p>
<p>blah blah bla measure carbon something. Mesh bags were used.</p>
<p>The way I interpreted it, they were just describing the procedure, but not necessarily stating that mesh bags were used to measure mass</p>
<p>ok i don’t remember that. and im pretty sure carbon levels were not measured</p>
<p>That was what the part in the passage said, I’m just letting you know. Maybe someone with a photographic memory can recall that whole thing and help us out, lol</p>
<p>I mean, I only put down water/air because i thought it was common sense or something. I just never remembered specifically reading it in the passage why the mesh bags were used. Now, people are saying “it was stated specifically in the passage that mesh bags were used for ____”</p>
<p>But as far as I can recall, that part just said something like: blah blah blah measure something. Mesh bags were used.</p>
<p>hmmm you mite be right, i don’t think i read the passage very cleary cuase i was rushed. i remember some of the graphs measured content and the others mass. And air and water do have mass… hmmm if only someone could find the experiment where they got the question from</p>
<p>Wasn’t the whole point of this experiment was to measure how much mass of the litter there was in the mesh bags after a certain amount of time? That means that the mass of the litter had to be able to move in and out of the mesh bags.</p>
<p>But then again, I might be wrong.</p>
<p>Kangster brought up a good point though, air and water DO have mass, lol. Honestly, I don’t think the litter would be small enough to move through the mesh.</p>
<p>Prideful</p>
<p>Water/Air</p>
<p>It was definitely prideful. 100%</p>
<p>And I put water/air. I read back on the passage, and LaTina is right–it merely mentions that they used mesh bags with the experiment. It was our job to find out why. In other words, it was not directly stated in the passage. The point of the experiment was to find out how much mass of litter would be in the bags after a certain amount of time… so litter might be the correct answer, here. Litter would need to pass in and out of the bags (hence the mesh), and the bags would keep in the litter that didn’t decompose. Either way, water and air would need to be in contact with the litter regardless of the mesh bag. So if you’re viewing the problem from that viewpoint, the answer would be litter. BUT if you look at the problem by mentally comparing a mesh bag with a non-mesh bag (AKA a solid-walled one), then air and water would have validity as an answer. A meshed bag would allow the air and water in, whereas a non-meshed bag wouldn’t. Digging even further, a non-meshed bag wouldn’t let litter out, either, which would be needed in the experiment. I think the question was questionable or even paradoxical, but in the end, I think I’m agreeing with all those “litter/mass” people out there. I’m probably wrong on this one…</p>
<p>^My only problem with the “litter” answer is that by letting litter pass out of the bag, you would also have to let litter pass into the bag as well. Doing so would completely skew the results, which depend upon the weight of the bag after a specific time interval</p>
<p>^ How is litter going to pass into the bag…? Actually, do you guys know how big plant litter is? I really don’t see how plant litter is going to pass in/out of mesh bags anyway. (did they crush up the litter or anything?)</p>
<p>Then again, the experiment was only about the mass of the litter. Why would they want water and air to pass in/out of the bags?</p>
<p>I can see both sides for mass and water/air. I really have no idea which is the right one. If someone brought up the passage, I think we can figure it out, lol.</p>
<p>For the Wright brothers, thanks to SoccerRyan posting the passage, I think most people can see why prideful is the better answer. The people who are arguing for the other choices aren’t looking at what the question is specifically asking for.</p>
<p>Well one of the main reasons I picked mass was because that is what the experiment was measuring, sunlight and water seemed like the best wrong choice because most people would naturally pick that without looking at the purpose of the experiment.</p>
<p>pride
water/air</p>
<p>^^The purpose of the experiment was to examine the effects of heat on decomposition. Could the scientists test this by sticking the soil (along with the heat rod thing) in a steel box and then burying it underground? No. If they had done this, what would their results prove? Nothing, because the soil would not have been in its normal atmosphere under normal conditions- that is, outside, exposed to the elements, including water and air. Without these two, the scientists’ conclusions could not have been supported as they wouldn’t have seen how heat effects the soil in the natural world. This is why I think they used the mesh bag: the bag would expose the soil to the same conditions that the surrounding soil (such as air and water) experiences without letting other matter contaminate the experiment. </p>
<p>That’s just my two cents anyway.</p>
<p>Hmm, seems prideful and water/air are pretty unanimous. Guess we’ll just have to wait until results come out and ask people with 36s on Reading/Science to see which answers they put to truly find out.</p>

<p>The purpose of the experiment was not to test soil, it was to test the decomposition of leaves. *** ARE YOU TALKING ABOUT. Also how the f is burried soil exposed to air. don’t even post if you have no idea about what the passage was talking about</p>
<p>^ Woah buddy, chill out. o_o He never said the experiment was to “test soil”. Read it again carefully before you make a reply.</p>
