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

by an experiment with potato and glucose/salt solution. The experiment requires putting a piece (or more) of potatoes into glucose or salt solution to see the result of osmosis (a hypertonic type of solution is mostly used as it would give the most prominent visual prove of osmosis‚ as was mentioned in an observation of an experiment). As the potatoes are left in the solution‚ water molecules from the potatoes would move out through the semipermeable membranes to the hypertonic solution surrounding

The “Couch Potato” Lifestyle “Couch potato”‚ a slang term to describe a person who spends most of the time sitting or lying on a couch. However‚ sedentary lifestyle is another term which commonly used as a medical term to describe a lifestyle with irregular psychical activities or exercise. People intend to spend more time sitting‚ surfing the internet‚ working on a computer‚ watching television‚ and other activities that do not require much psychical movement or activities. Hence‚ this lifestyle

Compared to the deaths of the holocaust which would stand at 11 million. 94 million is a to high number‚ when dealing with innocent lives.

different situations: hypertonic solution‚ isotonic solution‚ and a hypotonic solution. A hypertonic solution is when there is a higher concentration of salts dissolved outside the cell and pure water inside the cell‚ the water rushes out of the cell to try to dilute the salt solution causing the cell to shrivel up. An isotonic solution is where the water has achieved equilibrium with concentrations inside and outside of the cell‚ so there is no alteration of the cell. A hypotonic solution is where there

Aquarius(Sports Drink) Background Aquarius is a new isotonic sports drink launched in Asia at the year 2012 by The Coca-Cola Company. Aquarius was introduced in Japan in year 1983 as a grapefruit flavored sports drink as a response to compete for market share with other isotonic sports drinks such as Pocari Sweat‚H2O and 100plus.Aquarius was also the official sports drink for Olympics game in Barcelona in 1992 and 2012.As it’s a new launch product in Asia‚ there’s a need to create awareness to

Using Sucrose Solutions to Determine Osmolarity of Potato Tubers Based on Weight By Thomas Pelikan Biology 200A Section 004 Kimberly Schmidt October 2‚ 2012 Abstract: In this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubating them in solutions of sucrose with varying molarities. To find the osmolarity we took a potato and used a cork borer to obtain seven samples of potato tubers. We then prepared seven beakers with concentrations

Effect of Osmosis on Potato Aim: To investigate the effect osmosis has on potato pieces that are placed in different concentrations of sugar solutions in water. Hypothesis: I believe that the more saturated the solution is the lighter the potato will be‚ and the potato in the clear water will weigh more after being left in the solution over a 24 hour period. This is because the cell membranes in the potato act as semi permeable membranes (meaning that they only allow certain molecules through)
