WHO:The electric battery, the most commonly used battery, was invented by Alessandro Voltathe
WHERE:Como, Italy WHEN:1800 |
|
The battery is a portable source of energy used for many electrical appliances. There are two basic types of batteries: the Primary Cell and the Secondary Cell. The most common type of Primary cell is the electric battery. The interior of the electric battery is made up of different liquids, while the exterior is a thin covering of plastic. The most commonly used Secondary Cell is the Lead-Acid Storage Battery, which is used for powering automobiles. The Lead-Acid Storage Battery is very big, about the size of someones head, and has a hard rubber covering. The electric battery, the most commonly used battery, was invented in 1800 by the Italian scientist Alessandro Volta (1745-1827). Alessandro was born in Como He named the term volt after himself. Volta had always been interested in electricity, and gaseous fuel. Around the end of World War II, there was a need for a portable energy source that could transfer energy into an electric appliance. Alessandro Voltas electric battery was an important thing to have for electric appliances or for automobiles. The electric battery was a big hit back then, because it was the first portable energy source. You did not have to plug your machine into an electric socket. |

Silver, metallic, smooth. I clasped the small object in my hand. I could almost feel the fluid rushing through the inside of it. I imagined the genius, Alessandro Volta, who invented such a clever object. I held it up, examining the surface for any scratches or flaws, Its cool texture refreshed my sweaty hand. I could imagine all of the electrically charged particles scurrying about in the battery, And I wondered how it was all possible. |

My Invention: a size D battery
In the fall, every student picked an invention. I picked the battery. We each researched our inventions thoroughly, and now in math, we are finding the volume of our inventions, trying to fit them in a rectangular box, and seeing how many of those boxes would fit in the "Morrison Forum" in the Middle School. Our assumptions for the forum were that we took out all of the poles and other protruding objects, while calculating the volume, assuming that the Forum was a perfect cylinder, with a perfect cone on the top.
Volume of the Morrison Forum= 23,426.22ft3 First, I had to convert the Volume of the forum, 23,426.22 ft3, into cubic inches. 23,426.22 ft3 = 40,480,508.16 in.3 Now all I have to do is divide the volume of the Morrison Forum by the volume of one battery
40,480,508.16 in.3 Number of size D batteries that fit in the Forum= approximately 4,497,834 batteries My estimation was 6,000, so as you can see, I was a bit off.
For the next part of our assignment, we had to calculate the volume of the Grand Canyon. We assumed that the Grand Canyon was a perfect prism, which is certainly not true; also, we estimated the length to be about 277 mi, the average width, 10 mi, and the approximate elevation (South and North rims) came out to be about 1 mile. Now we use the volume of our invention (7.85 inches cubed) and divide it into the total area of the Grand Canyon (2,770 miles3) The volume of the battery,7.85,/12/12/12= .0045428241 feet3 The volume of the Grand Canyon, 2,770 mi, * 5280 *5280 *5280= 407,738,327,000,000 feet3 Finally, I divide .0045428241 feet3 into 407,738,327,000,000 feet3 for my answer of how many size D batteries will fit into the Grand Canyon.
407,738,330,000,000 feet3 Answer= 89,754,373,000,000,000 size D batteries can fit into the Grand Canyon. My Guess, 500,000,000,000 Again, as you can see--I am way off!
