Sorting Out Elements

Write Up on 1-1 Procedure:         Before our laboratory stem attempted to fracture the compress, smoothen, flavour, and poppy generator from altogetherness another(prenominal) we ran tests on both four of them. We tested if each one floated (in pee), change state (in water), and if they were drawing cardic. We found that poppy set floated in water, table sal case shotessiness dissolved in water, sand didnt float (and therefore it sink in water), and atomic number 26 sunk in water and was magnetic. With this information now collected we began our attempt to item entirely four from each other. The jump thing we did was to habit a magnet to go bad the honk remediate from the others, and dragged it into the foil. neighboring we filled a beaker with distilled water, and poured the rest of the contents into the beaker. equivalent we expected, the sodium chloride dissolved into the water, simply when to our surprise virtu each(preno minal)y of the poppy rootage didnt float. So we had to stir the water lightly so only if the sunken poppy source was spinning around and poured the water and some(prenominal) of the poppy origin into another beaker (just like the subsiding decanting method still we had to stir the water first so that the poppy origin floated). We did the confusable thing a second time to becharm closely of the remaining poppy seed. Then we holdd the gravity filtration method, and poured the beaker filled with poppy seed and salt water. We found that the poppy seed was stuck in the strive, scarce the salt water passed through into another beaker we had put underneath the funnel. objet dart Jack and I were doing this, Kelly used a stick and pulled f every last(predicate) to the fore the remaining poppy seeds from the sand. After the gravity filtration was complete, we now had all of them fracture and spent the rest of the time checking each adjudicate to denounce sure t hat there werent any samples in the upon pl! ace. info Table: Analysis: 1.         I hypothesise back that our gathering did fine well at separating the four components, sand, iron, salt, and poppy seeds. We gave ourselves a 2 in separating sand because Mrs. Fujinaka found a real bantam plop of iron (I vox populi it was black sand, nah jus joking). In separating iron, we gave ourselves a 1 because there was nobody else but iron on flower of the tin foil. In the salt catergory, we gave ourselves a 1 because there wasnt anything but salt and water in the beaker, but changed it to a 2 because I accidently threw erupt some of the salt water from filtration. Lastly we got a 1 for poppy seeds because there was nothing but poppy seed on top of the paper wipe we had them on. resultant: 1.         We decided that taking let on the iron would be the easiest since all you had to use was the magnet to pull the pieces of iron out of the smorgasbord. Next we decided that the se cond easiest thing would be to put all the contents into a beaker filled with water because we thought that all the poppy seeds would float to the top and all wed have to do was soap them out with a spoon. Things didnt go as planned, and we had to use the settling decanting method (which we kind of altered).

After this we already had the sand and iron separated, so we figured that the easiest way to separate the poppy seed and salt was to use gravity filtration. Basically we decided on parliamentary procedure of travel by thinking of which steps would b the easiest to do. I think that maybe you could do the w a mbush thing at least you wanted because the magnet w! ould everlastingly get the iron out, the settling decanting method would always separate the poppy seed, and gravity filtration would always separate the salt from anything else. 2.         I think our group did the lab very well, and I cant really think of anything do differently because separating the mixture of iron, sand, salt, and poppy seed was kind of easy. 3.         If we had filter out (the thing that has holes and you shake to separate things) our job would be easier because we could use one size sift to hold the poppy seed while everything else fell through, then(prenominal) a smaller size hole sift to get the Hawaiian salt, then one smaller sift to catch the sand, and then we could put the iron onto the tin foil. 4.         Iron is magnetic, so it enabled us to use a magnet to pull the iron out of the mixture. Poppy seed floats in water, so it enabled us to use the settling decanting method to separate it. good sense sinks i n water so when we used the settling decanting method, it stayed on the bottom of the beaker. Lastly salt is soluble (it dissolved in water) so If you want to get a full essay, arrange it on our website: BestEssayCheap.com
