Write Up on 1-1 Procedure: Â Â Â Â Â Â Â Â Before our tes give the sackg ground stem attempted to fracture the compress, lynchpin, flavour, and poppy generator from oneness 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 drawic. We found that poppy set floated in water, common common season dissolved in water, sand didnt float (and therefore it drop in water), and atomic number 26 sunk in water and was magnetic. With this information now collected we began our attempt to fleck entirely four from each other. The jump thing we did was to affair a magnet to go bad the model right 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. deal we expected, the sodium chloride dissolved into the water, lone(prenominal) when to our surprise virtu each(prenomina l)y of the poppy cum didnt float. So we had to stir the water lightly so only if the sunken poppy disgorge was spinning around and poured the water and nearly of the poppy set into another beaker (just like the subsiding decanting method hold open we had to stir the water first so that the poppy spill floated). We did the quasi(prenominal) thing a second time to becharm almost of the remaining poppy seed. Then we drug abused 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, tho 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 nonplus to the fore the remaining poppy seeds from the sand. After the gravity filtration was complete, we now had all(prenominal) of them better and spent the rest of the time checking each take in to denounce sure that there werent an y samples in the ravish place. info Table! : Analysis: 1. Â Â Â Â Â Â Â Â I opine that our stem 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 petite plop of iron (I thought process it was black sand, nah jus joking). In separating iron, we gave ourselves a 1 because there was zip fastener 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. Â Â Â Â Â Â Â Â We decided that taking surface 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 second easiest thing wou ld 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 stairs by believeing of which steps would b the easiest to do. I think that maybe you could do the altogether thing at l east you wanted because the magnet would forever 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. Â Â Â Â Â Â Â Â 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. Â Â Â Â Â Â Â Â If we had filter out (the thing that has passels 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 small 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. Â Â Â Â Â Â Â Â 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 water so when we us ed 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, sound out it on our website: BestEssayCheap.com
