The Effects of Different Salt Solutions on Potatoes Plan My aim is to investigate how different concentrations of salt solution affect the movement of water through a partially permeable membrane (osmosis) in potatoes. Osmosis is the movement of water from a high concentration to a low concentration through a partially permeable membrane. I will add pieces of potato to varying concentrations of salt solution, wait on each solution and then record the results. I will eventually use the
Concentrations of Salt Solution on Potato Tissue My preliminary work involves me preparing for my actual experiment. I will do the experiment and record my findings; however it is merely a practice for the real thing. This will allow me to correct any mistakes that I may make in this task and allow me to change them, if needed, in the forthcoming project. Apparatus list for my preliminary investigation: * Cork borer. * Potato, * Salt solution (0 – 100% solution), * Distilled
Concentration of Salt Solutions on Potato Tissue Title: An investigation into the affect of different concentration salt solutions on potato tissue Aim: .I have to find out the effect of varying salt concentrations on a potato tissue. Also to find out how osmosis occurs with different salt concentrations from very dilute to very concentrated. I will be looking for any changes in mass and length Prediction: I predict that the most concentrated salt solution (1 molar) will be the solution that will
The Effect of Salt Solution Concentration On The Mass Of Potatoes Introduction ============ In my investigation to find out how salt solution concentration affect the mass of potatoes, I will investigate how much the mass of a potato changes if I leave it in a beaker of water with a specified salt concentration for half an hour. I will change the salt concentration after each experiment. Background Knowledge -------------------- Osmosis is the passage of water molecules from
The Effect of Soaking Raw Potato Chips in Various Salt Solutions Aim In my Experiment I hope to discover the possible concentrations of potato cell sap using osmosis. Osmosis is the passage of water molecules from a weak solution into a stronger solution through a partially permeable membrane. We hope to achieve this by doing four experiments using distilled water in one test tube and different concentrations of salt water in the other test tubes. Once done, we will measure the change
Experiment to Find the Reaction of Potato Chips in a Salt Solution Aim: to find a reaction of potato chips in a salt solution. Hypothesis: I predict that the potato will change in mass. The difference will occur in accordance to the difference of concentration of the salt solution each potato chip is submerged in. The cause of this change in mass is called osmosis. Osmosis is the movement of water through cells in plants. I make my prediction on the pretext that water diffuses from
Concentrations of Salt Solutions Introduction: Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water potential to a region of low water potential. It can be affected by several different variables including concentration of salt solutions. When a plant cell is put in pure water it will become turgid and it will not burst due to the presence of a cell wall and a large permanent vacuole and when it is put in a concentrated solution it will be plasmolysed
Investigating The Effect Of Concentration Of Salt Solution On The Mass Of Potato Chips Aim: The aim of this investigation is to see whether the amount of salt solution affects the mass of the potato chip Hypothesis: In the solution below, water will diffuse from the dilute solution into the concentrated solution through the process of osmosis. Therefore the dilute solution level will fall and the concentrated level will rise Line Callout 2: Disapproved (is unable to go through
Osmosis of Potato Cells in Various Salt Solutions Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is not important as Osmosis is
of a Salt Solution Affect Osmosis in a Potato Factors ======= Factors that could affect the experiment: - · Temperature of water · Type of potato · Amount of solution · Amount of time the potato is in the solution Factors that I will change in my investigation: - · Percentage of salt in solution Preliminary Equipment ===================== 7 Beakers (250ml) 7 strengths of sugar solution (100ml of each strength) as follows 1x 0.0% salt 1x 0.5% salt 1x
chips are equally variable. Preliminary Experiment As evidence Label 3 specimen tubes A B and C. Add your name to all 3. Using a measuring cylinder, pour 20cm3 of water in tube A and 10cm3 in tube B. Similarly, pour 20cm3 of 17% sucrose solution in tube C and 10cm3 in tube B. Working on a white tile, cut 6 cylinders of potato tissue out of a large potato using a cork borer. Work in the same direction. Cut all 6 to exactly the same length, eg 50mm, 60mm etc. Trim the ends at 90 degrees
round the osmosis process that takes place in potatoes. Osmosis is the intake of a salt solution through a selectively permeable membrane. The strength of a salt solution can have a dramatic difference on the amount the potato can take in, and how it reacts. Here is an example of a selectively permeable membrane… Salt Solution [IMAGE][IMAGE] Strong Weak [IMAGE] Strong Weak Salt Solution [IMAGE] Variables: An fundamental necessity in my biology experiment
investigate the strength of cytoplasm in potato cells. VARIABLES Strength of solution Weight of potato Length of potato Volume of solution Temperature of the room Type of potato Size of potato WHAT I ALREADY KNOW I know that osmosis is when water molecules move from a weak solution to a strong solution through a semi-permeable membrane. PREDICTIONS I predict that the stronger the salt solution is the more likely the potato will weigh less than what it did at the start
Sewage Treatment Where does the wastewater go? When water goes down your sink or toilet, it travels through small pipes to much larger trunk sewers. The sewer systems are built to the slope of the ground around the Elbow and Bow Rivers. This slope allows most of the waste to go down by gravity, rather than expensive pumps, to one of four plants. To handle low areas, which do not have enough slope, pumping stations have been made. How is wastewater treated? Wastewater treatment in Calgary
Ever since the Roe v. Wade Supreme Court decision in 1973, Abortion has changed its course in society. With the new decision made by the United States, abortion was now legal. Many abortions were performed before the Supreme Court decision, but the settlement made it less risky for the doctors involved. Abortion has caused society to be divided by a pro-choice group and pro-life group. Two groups with struggles that will never end. There are many different types of abortions that can be preformed
viscosity of a non-Newtonian fluid is also dependant on temperature. Cornstarch would decrease in viscosity if put in a boiling pot (it would become thinner). Examples of Newtonian fluids include motor oils, mineral oils, gasoline, kerosene, and most salt solutions in water. The most popular explanation for the behavior of cornstarch and water is that when sitting still, the tiny grains of starch are surrounded by water. The surface tension of the water keeps it from completely flowing out of the spaces
have chemicals inside to store energy. When two different metals that are connected by a wire are placed into an acid, a potential difference (voltage) is produced. This occurs because the metals react with the acid forming Hydrogen acid, a metal salt solution and an electric charge. The charge flows from the most reactive metal to the least reactive metal. Equipment The equipment used will be: · Acids · Metals · Wires · Voltmeters · Beakers · Measuring cylinders · Stop watches · Sandpaper Method
of a solution is a measure of whether it is likely to lose or gain water molecules from another solution. A dilute solution, with its high proportion of free water molecules, is said to have higher water potential than a concentrated solution, because water will flow from the dilute to the concentrated solution (from a high potential to a low potential). Pure water has the highest possible water potential because water molecules will flow from pure water to any other aqueous solution, no matter
This is where a tube attached to a vacuum is inserted into the uterus and sucks out the embryo and all other material. The second type takes place after the 15th week and is called saline infusion. Here, the doctors replace a little fluid with a salt solution. This causes the uterus to contract. The fetus is then expelled. The third type is a hysterotomy. This is a similar procedure to a cesarean section. The only difference is, in this operation, is that the cut is smaller and lower. The fourth type
