The Science of the Spud — a History of the Potato Battery Experiment There are hot potatoes‚ french fried potatoes‚ baked potatoes and scalloped potatoes. There are potato chips‚ potato pies and potato soufflés. Last‚ but not least‚ there’s the potato battery. Who on earth invented the electric spud? Why does it work? For that matter‚ why would anyone want to see if a potato could conduct electricity in the first place? Well‚ we may never be able to answer some of the questions this quirky experiment

original 1M solution of Sucrose. This is therefore the only thing that is going to be altered as I am investigating how different percentage of water molecules affects the weight of the the potato thus the rate and direction of osmosis. Dependant Variable The dependant variable will be the mass of the potato as this is the variable I will be measuring. From this I can see the change in mass(g) and so work out the amount of water that has moved and the rate of the osmosis in a set time. This can

Exchange‚ which started mostly after 1492 when Columbus traveled from the Old World to the New World‚ can be defined as the time when various items such as plants‚ technologies and food were carried from the New World to the Old‚ and vice-versa. The potato is a great example of the Columbian Exchange‚ seeing as how it was carried from the New World to the Old World‚ and had a significant impact on Europe‚ as well as other countries from various continents. Potatoes were first known to be grown in the

tissue would loose more weight the higher the solute factor in the outside solution. When the potato tubers’ where placed in high-‐in-‐solute solutions it dehydrated the the potatoes tissue making it loose weight. The water inside the potato was forced to leave the inside of the tissues cells because of the higher solute

are substances that do not dissolve into a true solution‚ such as large protein molecules. The solution that can dissolve a solute is called a solvent. The concentration of solutes in the body fluids is referred to as the osmolality and the term tonicity referrers to the osmolality of a solution. The cells in the body are exposed to three different solutions classified as isotonic‚ hypotonic‚ and hypertonic. Isotonic solutions have the same osmolality as body fluids. They do not change the size

Calcium can be viewed as the most notable change because of lead’s ability to replace calcium in many of the intracellular regulatory procedures. Calcium is an intercellular mediator that acts either as a signal or a secondary messenger for many functions of the submandibular glands. This decrease in the absorption of calcium is believed to cause the destruction of the mitochondria which causes rapid energy depletion and impedes transportation. This will stop cells from their normal function and

VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass
Premium Concentration Chemistry Osmosis
Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes
