    Factors Affecting Osmosis The aim of this experiment is to investigate the factors affecting osmosis. I have chosen to investigate the effect varying concentration of sucrose solution has on the amount of osmotic activity between the sucrose solution and a plant cell. The plant cell I have chosen to use is a potato tuber from which I plan to cut potato chips of equal length which I will place in test tubes filled with varying concentrations at equal volumes of sucrose solution. After a

    The Factors Affecting Osmosis in Potato Tissue Planning In this coursework I am investigating the factors affecting osmosis in potato tissue. [IMAGE] Osmosis is defined as the net movement of water molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell membrane, which lets smaller molecules such as water through but does not allow bigger molecules

    Factors Affecting Osmosis in Potato Tissue Introduction: I am going to design and modify an experiment used to show osmosis in potato chips in different concentrations of sucrose solution. I am also going to investigate on how potato chips change in volume and weight when placed in different concentrations of sucrose solution. I will also conduct a preliminary experiment before my final experiment. Aim: To investigate the effect of different concentration of sucrose solution on potato

    Factors Affecting the Rate of Osmosis Plan Aim To find out if osmosis occurs in a potato, and to observe how different concentrations of a solution affect the rate of osmosis in the potato. What Is Osmosis? Before actually planning the experiment, I will do some research to find out about osmosis, and matters related to it, so that I can make predictions and work out a way to make this investigation fair and safe. Planning ahead would assist me in finding out how to do what, when

    An Investigation Into the Factors Affecting Osmosis Problem. In this investigation I am trying to find the effect of placing potatoes cut into French fries into salt solutions of different concentrations and the subsequent percentage difference in weight between potatoes placed in different salt concentrations. Hypothesis. Osmosis is the transfer of water from a region of high water concentration through a selectively-permeable membrane to a region of low water concentration. A selectively-permeable

    Investigating the Movement of Osmosis through a Selectively Permeable Membrane My aim for this experiment is to see the percentage increase decrease and results of potato tissue's mass difference, when placed in different concentrations of sugar solutions. This investigation would expect to have 3 different variables, Independent, which you can change, the thing that I will be changing in this investigation for the factors affecting osmosis, is the concentrations of the solution that changes

    Investigate the factors affecting the rate of Osmosis Planning Osmosis is the diffusion of water from a lower concentration of solute to a higher concentration of solute, through a partially permeable membrane. In a high concentration of water the amount of solute (e.g. sucrose) is low. This could be called a weak or dilute solution. In a low concentration of water the amount of solute is high. This could be called a strong or concentrated solution. When a partially permeable membrane divides two

    An Investigation of Factors Affecting the Rate of Osmosis Introduction Osmosis is the movement of water molecules across a semi permeable membrane from a region of high water concentration to a region of low water concentration. [IMAGE] A semi permeable membrane is a membrane with very small holes in it; they are so small that only water molecules can pass through them. Bigger molecules such as glucose cannot pass through it. In actual fact water molecules pass both ways through

    proportional to the potential difference (p.d) across it (providing the temperature remains constant). The formula for calculating resistance is: Resistance, R=p.d across the wire (V)/current through the wire (I) R=V/I There are four factors affecting resistance: •length •cross-sectional area •material •temperature Electricity has a lot of different uses. It can: •heat things up •magnetise things •produce light •break down some solutions and compounds.

    An Investigation into Factors Affecting Resistance of a Wire Plan: The possible variables I could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire. I will use cross sectional area of wire and length of wire because I think it will be hard to draw conclusions from the material of wire. I am not doing temperature because it would be hard to get results from and I think they wouldn't be as accurate.
