salinity of solutions has on the process of osmosis and net weight gain/ loss by potato cells. This would be done by using similar size potato cubes and covering them with different concentrations of saline solutions (0.5% and 2.0%) in beakers then measuring the change in weight of the potato cubes. If the salinity of the solution is high then the weight of the potato cubes will decrease. Materials • 9 X 2cm2 potato cubes • 3 X

Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials: Test tube rack 4 test tubes Graduated cylinder Beaker 10-15 mL of hydrogen peroxide Potatoes Raw potato Potato soaked in baking soda Potato soaked in baking soda

research project. The purpose of this experiment is to prove that radish extract can be used as an insecticide. The researchers first gathered all the materials needed to complete the experimentation. First washed‚ sliced‚ and pounded the radish tubers using the mortar and pestle. Then the researchers extracted it by using a clean strainer‚ strained and acquired the juice of the radish. After completing the three setups‚ the researchers sprayed it on the insects and observed what happened. They

molecules are randomly distributed throughout an object‚ with all areas having an equal concentration.For this particular investigation I think that the lower the concentration of the salt solution in the test tube‚ the larger the increase in mass of the potato chip will be. This is because the water molecules pass from a high concentration. Therefore‚ I believe that the chips that are in the tubes containing a higher concentration of water than salt will have a larger mass than chips in tubes with higher

duration of 24 hours in varying concentration levels (2%‚ 5%‚ 10%‚ 20% and 25%) of sodium chloride (table salt)? HYPOTHESIS Solanum tuberosum L. final masses will decline as the concentration (2%‚ 5%‚ 10%‚ 20% and 25%) of sodium chloride increases. Potato slices placed in distilled water will have higher mass percentage due to the cells becoming turgid. BACKGROUND INFORMATION Diffusion is the movement of molecules from a hypertonic (high concentration solute) to the hypotonic (low concentration

commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted and towards a stimulus that is favored. Different stimuli which can cause taxis to occur are light‚ sound‚ moisture‚ heat‚ or chemicals. To narrow the possibilities‚ this specific trial will test whether potato bugs favor fresh water environments

SCM3006 Operations and Supply Chain Management Group Project Product: Baked Potato 1. Introduction 1.0 Introduce Baked Potato A baked potato is sometimes called a jacket potato in the United Kingdom. The baked potato has been popular in the UK and French for many years. In the mid-19th century‚ jacket potatoes were sold on the streets by hawkers during the autumn and winter months. In London‚ it was estimated that some 10 tons of baked potatoes were sold each day by this
