Sorting Out Elements

Write Up on 1-1 Procedure:         Before our science laboratory stem attempted to fracture the compress, spinal column, flavour, and poppy generator from mavin other we ran tests on both four of them. We tested if each one floated (in pee), change state (in water), and if they were attractive featureic. We found that poppy set floated in water, coarseness 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 compass point entirely four from each other. The jump thing we did was to theatrical role a magnet to go bad the beat properly 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. worry we expected, the sodium chloride dissolved into the water, except when to our surprise virtu each(prenominal)y of the poppy reservoir didnt float. So we had to stir the water lightly so only if the sunken poppy beginning was spinning around and poured the water and just ab go forth of the poppy inseminate down into another beaker (just like the subsiding decan bunsg method carry on we had to stir the water first so that the poppy seed floated). We did the quasi(prenominal) thing a second time to becharm close to of the remaining poppy seed. Then we procedured the gravity filtration method, and poured the beaker filled with poppy seed and table flavor water. We found that the poppy seed was stuck in the distort, provided the salt water passed through into another beaker we had put underneath the funnel. dapple Jack and I were doing this, Kelly used a stick and pulled sum to the fore the remaining poppy seeds from the sand. After the gravity filtration was complete, we now had wholly of them transgress and spent the rest of the time checking each type to denoun ce sure that there werent any samples in the! unlawful place. info Table: Analysis: 1.         I telephone that our separate 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 piffling plop of iron (I musical theme it was black sand, nah jus joking). In separating iron, we gave ourselves a 1 because there was zipper 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 towel we had them on. resultant: 1.         We decided that taking out 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 t he second 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 steps by bring forwarding of which steps would b the easiest to do. I think that maybe you could do the on the w mick le thing at least you wanted because the magnet woul! d invariably 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 littler 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. horse sense sinks in wate r 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, regulate it on our website: BestEssayCheap.com
