3. Using available cutters (Scalpel, Razor Blade, Cutter) to slice the potatoes into 6 groups of 3. slices with semi-even slices. 4. Weigh the 6 groups of potatoes with the Digital Weighing Scale, record the result. 5. Prepare all 6 200ml-beakers, rinse them with water, then fill them up to approximately 200ml. each.
PDF Effects of Potato Submerged in Saltwater to Demonstrate Osmosis
Step 1: cut 4 equal size pieces of potato using a corer of knife. Be sure the dimensions are the same. Aim for 1cm/1cm/8cm, and then record their exact dimensions and weight on a piece of paper. Step 2: Make your saltwater solution. Bring 500mL of water to a boil, remove from heat, and then gradually add salt to the water, one teaspoon at a ...
PDF Osmosis in Potato Slices
Tell them to: Pour the water into the cup with the sodium polyacrylate and stir with a spoon. Observe that all the water is absorbed (forms a gel) immediately. This is osmosis - the water moved into the white powder. Take out about 2 tsps of the gel and put back in to the 10 oz cup. Add 1 tsp salt and stir.

Lab Report: Potato Osmosis
Fill 6 beakers with 200ml of water, and then arrange the beakers in a line with 6 sets of potatoes. Thus, pair the sets of potatoes with each beaker. 3. Then, use a pencil and label the pairs of beakers with the potatoes using molar values (mol) (0.0, 0.2, 0.4,0.6,0.8,1.0) 4. Use a weighing scale 0.01g and weigh each set of potatoes.

Pour the water into the cup with the crystals and stir with a spoon. Observe that all the water is absorbed (forms a gel) immediately. This is osmosis -‐ the water moved into the white powder. Use the spoon to remove about 2 tsps. of gel and put it back into the 5 oz. cup.
PDF Osmosis Demo Lab
In this lab activity you will observe the effects of osmosis on plant cells. In the first part, you will use the weight of pieces of potato to see how much water moves in and out of cells in different salt solutions. In the second part, you will observe plasmolysis in an aquatic plant, Elodea. Materials (for each group)

BIOLOGY LAB REPORT: Osmosis in Potato Experiment. Christabelle Delfiona Taran 10E. Abstract: This experiment investigates the role of osmosis in cells; potatoes. The experiment also determines the changes that occur in the potato, which are; texture, size and color changes after soaking the potato in different 2 kinds of water solution.
In this experiment the semi-permeable membrane is the cell (surface) membrane. Account for the changes - if any - in the mass and length of the strips in water, salt solution and air. Strips in water. Description - Turgid; Mass - The increase in mass of the potato strip in water is due to the movement of water molecules into the plant cells via ...

8. Remove the potato/carrot from the salt solution. Do not stab or poke the potato/carrot with forceps when removing it. Using a paper towel, pat the potato/carrot dry. Measure the mass, and record in the data table. Record any other observations about the potato/carrot (color, texture, etc.). 9. Repeat step #8 with each of the other potatoes ...
Potato Osmosis Lab Report Draft
Potatoes also have large sugars like fructose and glucose that are unable to pass through the membrane by diffusion (osmosis). METHODS: In the experiment, two potatoes stored in different conditions are cored and placed in solutions of different NaCl (salt) concentrations in order to determine if the temperature affects the mass.
Science Experiments on the Osmosis of a Potato
This experiment helps students to differentiate between different degrees of concentration gradients. Make one salt water solution, one sugar water solution, and for the third solution, simply use tap water. Make three thin potato slices — 1/2 cm thick. Place each potato slice into each of the solutions, and leave the slices in the solutions ...
Lab Report Osmosis in A Potato
The lab report summarizes an experiment on osmosis in a potato. Three salt solutions with varying salt concentrations were prepared. Pieces of potato were placed in each solution and their weight measured before and after soaking for 20 minutes. As hypothesized, the potatoes decreased in weight the most in the highest salt concentration due to osmosis, where water diffused out of the potato ...

Place disk B in a separate beaker or plastic cup provided and cover with a solution of 0.9% w/v NaCl. In a third beaker or plastic cup provided, cover disk C with deionized water. Allow the potato slices to soak for 45 minutes. Make sure that the disks remain covered with the solutions during the entire time interval.
