Penny Battery Observations

Moreover, the demonstration in the article “Energy Story” was, the example shown in the article of what an atom is made up of was very detailed it showed electrons spinning around the nucleus, of atoms, in the same way the moon spins around the earth. Furthermore, the demonstration in “Conducting Solutions” the experiment that the article wrote was astonishing. The articles experiment contained water and salt and it explained how when a table of salt in water would dissolve only because the solution conducts very well because the solution contains ions and the ions come from the table of salt. Nevertheless, the clip ““Hands-On Science with Squishy Circuits” experiment that was shown was she was showing with homemade playdough created an example on how to create a circuit through play dough. Ms. Thomas was also talking about how if you put two pieces of sugar dough it has one hundred and fifty times more resistance than the salt dough she used. If you put a piece of salt dough in the middle than that’s when the led would work because to resistance substances won’t make it work but the one that has less resistance

In this experiment, we are trying to figure out how many droplets of water a penny can hold while face up. Before we began the experiment, we already knew that water molecules stick together as long as gravity isn't stronger than the water. In the experiment we had water, soapy water, and rubbing alcohol.

The U.S. penny has been a standard in our currency system for almost as long as our country has existed as a sovereign nation, but due to inflation, production costs, and the changing times we live in, it is no longer a sustainable unit of currency and only serves to increase our national deficit and waste our time. When the penny was produced for the first time in 1792 by the U.S. Mint, it was made of pure copper, featured a woman with flowing hair, and was inscribed with the words “Liberty”. Since then, the design and composition have changed numerous times to reflect our changing nation. Despite its fading glory, the penny has been kept alive by numerous false lobbying fronts and a stubborn ideology, but

This experiment was performed to observe differences in density based on the chemical makeup of an object. Pennies minted before 1982, pennies minted after 1982, and an unknown metal sample was tested to see if there were any differences in their densities. Ten pennies from each category and the metal sample were weighed using a scale to find mass and the displacement method was used to find their volumes. The masses and volumes were then used to calculate the densities of the pennies (D=m/v). The density of the pre-1982 pennies were 8.6 g/mL while the post-1982 pennies were 6.9 g/mL. The metal sample’s density was 1.7 g/mL. Following the experiment we were given the real densities of each item to calculate the percent error with the formula

The penny,has history, and it can help with charities, people are trying to get rid of the history and more that the penny has made through the 200+ years. Even though the penny costs more than its own value it can change the world. It has made many different communications though the world. Although the penny cost more to make then its price, the penny should stay, to help with charity,A middle school raised over $3000 in a week from a penny drive. The Penny also shows world history because of how long they’ve been around.

The purpose of this experiment was to find, compare, and contrast the mass, volume, and densities of copper and zinc pennies. Information about the pennies was acquired before the start of the lab. The pre-lab research stated that any pennies that were minted before 1982 are composed of pure copper, while any pennies after 1982 are made out of zinc. The densities of copper -- 8.96 grams per centimeters cubed -- and zinc -- 7.13 grams per centimeters cubed -- were also information that was acquired before starting the experiment. With knowing the density of the two metals, this hypothesis was formed: If the mass and volume of pennies made out of zinc and copper are both measured, then the copper pennies will have a greater mass, because copper has a greater density than zinc. This hypothesis was formed because density equals mass over volume and if the mass is greater in an object that has the same volume, then the density of the object will be greater than the other.

Pennies are used by Americans more than they realize. Parents give pennies to their children to throw into fountains in hopes of having their wish come true. Others rely on finding a penny on the ground for good luck. Despite the little value a penny holds, it may impact the economic status of Americans and charities, has importance in the pricing system, and remains as a part of American history.

In this lab we will be heating up substances and use them to galvanize pennies. When you heat up the zinc, and then coat the penny in it, it then galvanizes the penny. Meaning, it helps protect the penny from oxygen and water. Afterwards, you will need to record data such as the mass of the penny. This helps keep track of what physical traits are being changed during this experiment. On part B of this experiment, you will be heating up the now galvanized pennies in order to see what reaction you get. The reaction you should receive from heating up the now zinc-covered pennies is that the pennies will change color.

Money is crucial in many ways or everyday events like for buying food, paying rent, etc. Money has its own value but not all currency is used. Money has its own value but not all currency is used. The penny has the least amount of currency and is found on the sidewalk, sofa, in between car seats because nobody benefits form the penny. It doesn't have enough value to be kept around so lets just end the penny ones and for all.

Different metals have different mass and volumes. The mass and volume of something effect the density of the metal. If pennies made before and after 1982 have different densities, they are most likely made out of different metals. The independent variable is the year the pennies were made. The dependent variables are the density, volume and mass of the pennies. The controlled variables are the number of pennies, the instruments used for measurement and the environment in which the pennies are measured.

Though some parties may claim that the penny holds value to the United States, majority of the arguments presented are invalid or out of date. Examples such as the man who has saved “90 pennies a day” (Source B) are an extreme case that cannot be used to argue for continuation of the penny. In the average lifespan of an American denizen, it is improbable that one will have the time to collect this many pennies. In addition, on order for this man to reach his grand total of $13,084.59 took about forty years, making this argument illogical as the process is time consuming and one can save even more by simply collecting larger denomination coins. In addition, arguments made those countries such as the “EU … and Canada” that have kept their “penny”

Are pennies better clean or dirty? Clean, of course. Clean pennies are probably used more than dirty pennies, but maybe just clean all the dirty pennies with the products: orange juice, coca cola, and taco sauce and see which one cleans the pennies the best, so then just use those. If any of these products cleans pennies, then coca cola will clean the pennies the best. For independent variable it was the products and the dependent variable is the clean pennies. The control group is the coca cola and the experimental group is orange juice, coca cola, and the taco sauce. For this experiment there was only a few steps to do in order to have clean pennies. After all the materials are ready then pour the products into cups and put at least two pennies in each product. Once the products are in the cups then set timer for 30 minutes and repeat this step for three trials. Collect the weight of the pennies after 30 minutes each time and write it down to see which of the products took off most of the dirt on the penny. Collect all the other data that is needed. This is just one way that cleans pennies but

Have you ever had the struggle of having tons of pennies overflowing out of your pockets? Do you just have a mountain of change consisting of mostly pennies gathering dust on your dresser? What if there was a way to stop adding pennies to that useless pile of change? We can work together to make that happen. We can get rid of the penny completely. Even though the penny has large sentimental value in the US, the small, brown coin still costs more to make than it’s worth.

In the book Nickel and Dimed by Barbara Ehrenreich, who is a famous journalist and writer, she explores how low-wage workers survive in America by going undercover to learn for herself. Her project begins in Florida where she worked as a waitress. Her goal throughout the entire project was to manage enough money to pay a second month of rent. Ehrenreich fails at her first job . Ehrenreich then explores Maine where she begins living in a motel. Ehrenreich gets hired as a housekeeper at a nursing home and a maid . By the end of her time in Maine, Ehrenreich exposes who she really is. Ehrenreich then explores her last state, Minnesota. Ehrenreich finds a job as a retail worker and begins doing fine but later begins hating her job. It is to complicated looking at Ehrenreich's success or failure of the whole project because one can not say what one feels about the whole book because it is to long especially because ones paper to write is to short. Criteria is important because it brings satisfaction and it helps create a final decision. Did Ehrenreich show great effort during her project and were her experiences realistic? Although Ehrenreich slightly failed at experiencing

The debate over whether or not the United States should continue to create and use the penny may not seem very important, but it actually is due to cost and usage. Although the penny has a long history in the United States and can be considered an icon, in reality it is just not feasible anymore to continue to make the penny.
