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

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

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

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

gradient. Hypothesis: Will a high concentration of salt solution affect the mass of a potato chip? Variables Controlled variables: -The sizes of the potato chips. Bigger size of potato chips will weigh heavier and the smaller potato chips will weigh lighter‚ if we don’t use the same size of potato chips throughout the experiment‚ we won’t get an ideal result‚ there will be great differences between the mass of potato chips. -The duration of experiment. The duration of the experiment must be the same

Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

because they lived in forested areas and were usually close to water. In Eastern Woodlands society it was solely the man’s responsibility to hunt and fish. The women were in charge of farming‚ if they did any‚ and gathering various wild berries‚ nuts‚ tubers and other plants to eat from nearby forests. The Narragansett were well organized with central authority. They were governed by eight hereditary sachems each subordinate to the grand sachem who usually resided in the largest village.
