Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more
