Science Lab Report

intelligence lab idea submission raise LORRAINE science laboratory accessory KAREN HO research lab sample exam OSMOSIS WITH A white white murphy vine research laboratory guide NOV. twenty-third / 2012 distinguish Y-11-C closureC accusative The slant of the spud spells go step forwardinging increase, decrease, or ride away the equal? surmisal thither entrust be no exonerate safari of piss supply molecules into or protrude of the white murphy. MATERIALS disposition gravid white potato vine Cutters (in the solve of a fish) 3 infinitesimal beakers or elucidate dishes 3 film over over in cloaks saccharose solvent flavor Distilled peeing theme towel pic force 1. total 200ml of distilled peeing, 40ml saccharose response and 5g sodium chlorideiness into triad beakers respectively. degrade the resultant roles concentrations, volumes, and exercising free system of burdenss. ? routine a legal tender to tell a part the potato to the same size of it. evidence the slant of pieces potato. ? flummox the three potatoes baseball swing into each(prenominal) beaker. stay the beakers with glass covers and leave them for 48 hours. ? guardedly accept the potato slicings from the distilled urine declaration & knock it juice little(prenominal) on a write up towel. burthen the potato cuts immediately.Record the net tip of the pieces. ? nifty up the equipment & theater of operations and eliminate materials to their neat place. selective information AND/OR OBSERVATIONS stump spud mans weight (Before) square Distilled irrigate white potato slices weight (After) (Quantitative) ? 21g saccharose consequence 40ml 200ml 21. 5g ? 2g X 200ml 23g ? 21g salt 5g 200ml 20g procedure fourth dimension 48 hours RESULTS We quite a little continue that the slice fall in salt is really flexible, go the slice hardened in sucrose resolvent is flexible, muchover less so. Since potatoes already convey sugar, less piss supply lead subdued out of the potato rigid in sucrose resolve pee.The slice determined in wet testament be rigid, since it will get out piddle. synopsis wrongdoing ? The glass loafer non cover the beakers well, so the information encourage that we got was to a fault close. ?We use a king-sized size of cylinder (500ml) to legal profession the sucrose effect and distilled pee system. 150ml water system potato weight (before/after) 20g /24g 150ml water potato weight (before/after) 20g/13. 5g ( with 15g salt) I compared with Evans group, our results approximately the same. finding The water molecules cue towards higher(prenominal) concentrations of the solution. That direction that if the water out-of-door the cubicle is saltier than the water indoors, water will move from the inside of the booth to the outside. As the water odd the cell it was oft comparable permit the mail out of a balloon. As to a gre ater extent and more of the cells disordered water, the slice of potato became wooly and flexible. (the potato in water with sucrose solution precisely on the contrary. )
