hens produce a very high yield of around 300 eggs a year. Chickens will naturally live for 6 or more years but after 12 months‚ the hen’s productivity will start to decline. This is when most commercial laying hens are slaughtered. BATTERY CAGES In Europe‚ a battery cage typically holds 4 or 5 hens with a legal space allowance per bird of less than an A4 sheet of paper. The height of the cage is only just enough to allow the hen to stand upright. In the US‚ the space allowance per hen is even lower

Make a 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

When an ion gains or loses electrons without becoming neutral‚ its electronic charge is altered in the process. In chemistry the loss of electrons is called oxidation while electron gain is called reduction. The first battery was created in 1799 by Alessandro Volta .
