POTATO BATTERY Abstract a. Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. (Make sure to test your multimeter by connecting its Positive and Negative

those in the province‚ the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of phosphoric acid. B. Statement of the problem This study basically aims to find out whether a potato could be able to produce enough power to light up a bulb. And if it

Experiment #1 Preparation of Ethanol from Sucrose Based on R. Weglein & C.L> Yau‚ CHEM 203 Experiments in Organic Chemistry II Laboratory‚ 5th Edition‚ 2006‚ p29-32. Statement of Purpose: An aqueous solution of ethanol is prepared by the fermentation of sucrose. The percent alcohol is the resulting solution and the percent conversions of the sucrose are to be determined. Introduction: Sucrose is a molecule containing glucose and fructose. http://faculty.tcc.fl.edu/scma/phelpsj/experiments/ethanol

11. Then add the benedict’s solution to the sucrose beaker. Put water in the 400ml beaker‚ and put it on the hotplate to start to boil the water. 12. Then stand the test tubes in boiling water for a few minutes. 13. A color change through green to yellow‚ brown and finally to red indicates the presence of reducing sugar. 14. Repeat 3 times‚ washing the materials each time you finish one cycle 15. Then you have our standard for have a standard for the rest of the experiment. 16. Then you have a standard

Almost everyone that lives in this city knows about this restaurant‚ located in an area called the Quarry‚ because it is in the middle of many neighborhoods. Many people claim that Fleming’s has the finest slices of meat they have ever tasted‚ because at any other steak house‚ the meal is just average‚ along with the service.

of a higher water chemical potential to a region of lower water chemical potential. (Tzahi 2006) To demonstrate osmosis lab‚ artificial cells were made with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The phenomenon being investigated in the lab was how the concentration gradient affects the rate of osmosis

How To Grow A Garden It takes a lot of time and hard work to grow a garden. First you would have to start out small. You don’t want to bit off more than you can chew‚ or hoe. Like ‚ if you plant a huge garden‚ you’ll wish that you didn’t because of the hard work. Next‚ you must choose a location that receive as much sunlight as possible throughout the day. After you have located a spot to grow your garden‚ you should examine the soil. You will want to see if the ground is rich in top soil. Sometimes
