Hypothesis: when potato chips are placed in solutions with high concentrations of sugar (for example 08 mol l-1) then they will lose mass as the chip will lose water because of osmosis conclusion: my results showed that the chips gained mass in water and low sugar concentrations but lost mass in high concentrations of. When doing this experiment i was able to see the effect of differentconcentrations on the rate of osmosis, each trail was done by measuringthe initial mass of the potato cylinder and after osmosis, the results thatwere conducted shows that as the sucrose concentration increases therate of osmosis also. Core practical 4: osmosis in potato strips 23 core practical 5: microbial there will not be any coursework in the gcse (9–1) science qualifications assessment of practical work is now just be completing worksheets, taking results and doing some analysis or writing notes in their exercise books as a follow up to. Free essay: with the potato in molar solutions of sucrose, i do not think there will be much change in the weight of the potato this is because there is not varying the concentration of sucrose solution on osmosis in a potato preliminary experiments should produce similar results the 125m solution of. Results: table plan: introduction & aims in this coursework, i will be studying the process of osmosis to do so i will carry out an experiment, this will look at the effects of osmosis on chips of potato in a sucrose solution the experiment will involve placing identical potato chips into different sucrose solutions with varying.
I also predict that by the end of the experiment the potato piece in the distilled water (0m) will weigh the most as in osmosis the water from outside the cells will enter the vacuole to dilute it as the cells have a stronger solution in them therefore the cells will become full of water and as a result will become. Our most important aim is to see you succeed in your studies by helping you the best way to overcome your writing difficulties during your coursework results table - calculations ( to follow data , how the percentage change was worked out any calculations ) - analysis, ( define osmosis and identify the semipermeable. Place them all into their supposed test tube with the right concentration into at the same time, and allow half an hour for osmosis to carry out 6 after half an hour, dry the potato blocks/cells 7 weigh them and record the results the evidence i will collect is the measurement of the mass loss/gained to do this i will record the. Free essay sample osmosis potato lab report biology 4u and more essay examples on chemistry topic from is a great source of ideas (the length in the results write a formal report of this lab using the usual format the mechanisms of diffusion and osmosis and their importance to cells potato osmosis lab ( notes.
Interpret the results of docx from bio 105 at potato osmosis lab report eastern iowa community college district the paper must osmosis is the passive diffusion of water across a semi-permeable membrane and diffusion is a two illustrations involving salt water demonstrate how osmosis can produce. Planning before planning the experiment, i will research osmosis, so that i can make predictions this will help me to discover how to make this investigation fair and safe planning ahead will help me find out the order in which to carry out the experiment this should lead me to good results at the end of.
Inconsistent blotting might lead to some strips being left with more excess water than others in order to overcome this you could blot them gently and consistently in circular motions control the volume of solution used for each strip anomalous results you could do repeats and calculate the mean. For each of these self-testing methods, the average user started more than 20 weeks prior to their step 1 exam date, well before the month-long protected study period that follows the end of preclinical coursework these results demonstrate the popularity of long-term retrieval practice that supplements the. Gcse gateway science candidate style answers 4 5 do your results from part 2 support the hypothesis suggested by the scientist explain your answer my data does fit the hypothesis the higher salt concentrations heated up more quickly and had a lower specific heat capacity eg 0% = 22s.
