To begin with, pennies aren't the only coins that cost too much to make. According to Jeff Sommer, who wrote the article “Penny Wise,or 2.4 Cents foolish?” he states “Each

So green apple is green, grapes are purple, cherries are red, oranges are orange, and lemons are yellow. Then I stirred it until it looked good. Then I poured each mixture into their own small pans, make sure they are not glass pans because they will break. Then put the pans into a freezer and wait 4-5 hours or until mixtures are frozen. Then break them into smaller pieces about a nickel's size and put the pieces into the microwave and wait 40 seconds and it should be melted. Now they let the pieces cool and then roll them into balls, and then dipped it into tartaric acid. Let the balls harden.

Some people think that if we don't use pennies that if we get rid of the penny, that its will round

In this video it shows you how you can use the things that are something your children play with and are commonly bought things to create your own electricity. The lady in the video was using two types of playdough’s that she has made on her own. She made a salt dough, and also a dough including sugar rather than salt. When you put the two salt pieces’ together and a sugary piece in between, you can create electricity. The purpose of this video is to tell everyone about how you can conduct your own electricity and to explain how it can be used more simply than you think. It is not all about atoms and all of those substances. You can create electricity with what you have in your own house. She tested the playdough’s by putting an LED light in the salty pieces on the outside. If they touch the light will go out, but if you place a piece of sugary dough in between the two, you can leave the light on and it will stay on.

The play dough that has salt conducts electricity and play dough that has sugar has 150 time more resistance then the salt play dough and that when you put them together they create a circuit. If you put the play dough that has salt together I won’t turn the led

The penny, also known simply as the one-cent coin, was first made about 230 years ago in 1787. The first penny ever made was 100% copper and it was heavier and larger than the usual penny today. The design itself was suggested by the famous Benjamin Franklin ("A Brief History of the U.S. Cent”). Lately, people have talked about the idea of abolishing the penny, but others disagree. The penny should not be abolished.

5. A local grocery store was holding a contest to see who could most closely guess the number of pennies that they had inside a large jar. The first six people guessed the numbers 735, 209, 390, 300, 1005 and 689. The grocery clerk said the jar actually contains 568 pennies.

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.

During the first trial the penny held 17 drops of water. I used a dropper to put the drops of water on the penny very slowly while taking my time. In the next two trials it held 25 and 22 drops. In the last trial it held the most drops which was 30 drops of water. I think the last penny held the most

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”

Everyone has that one item that they cannot part with, even if it is battered and broken. That item has sentimental value. The same thing can happen to a penny. I love pennies and keep them. There is that sentimental value. Now, as many would say, they have no value for the penny, but that’s not true. Everyday there are phrases that are used, and those phrases come from the language. The penny has influenced it, giving us a number of idioms. Source #4 states many examples such as, “a penny for your thoughts,” or “not one red cent.” If we took away the penny these would lose their

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.

Sketch the side view of the penny just before the liquid spills over. (I suck at sketching so I'm doing a written description). First liquid (water) - There were 41 drops of the water. I saw Lincoln large than before I started the activity. Second liquid - There were 27 drops of the stroke alcohol.

Print out the image of a clock and open the spreadsheet called Grapher. You will find both of

First off, wash the lemons clean so there won't be any dirt or bacteria on the lemon. Use the knife and cut the lemon in half so the juice can be easily squeezed out of. If you desire more juice from the lemon, it is a good way to put the lemon in the microwave first for around 10 to 15 seconds. After cutting the lemon and squeezing about 2 cups of juice into the cup or pot, add around 6 cups of water. After adding water to the cup, add 1 and a half-cup of sugar to the juice and water. The most important thing to remember is that the ratio of juice, sugar and water makes lemonade great -- not too sweet, not too tart. I like 6 cups of water to 2 cups juice and 2 cups sugar. Adjust it to suit yourself. Also, don't forget how great hot lemonade tastes in the winter when you have a sore throat. You can freeze the lemon/sugar syrup for later use.
