Candy Coffee Filter Chromatography

You can do paper chromatography using a coffee filter to separate the pigments in colored candies, like Skittles or MM candy. This is a safe home experiment, great for all ages. Difficulty: Easy Time Required: about an hour Candy Chromatography Materials Basically, you need colored candies, a coffee filter or other porous paper, and salt water for this project. Skittles or MM candiesCoffee filterTall glassWaterTable saltPencilToothpicksPlate or foilPitcher or empty 2-liter bottleMeasuring cups/spoons Procedure Coffee filters usually are round, but its easier to compare your results if the paper is square. So, your first task is to cut the coffee filter into a square. Measure and cut a 3x3 (8x8 cm) square from a coffee filter.Using a pencil (ink from a pen would run, so pencil is better), draw a line 1/2 (1 cm) from the edge of one side of the paper.Make six pencil dots (or however many colors of candy you have) along this line, about 1/4 (0.5 cm) apart. Underneath each dot, label the color of the candy you will test on that spot. You wont have space to write the whole color name. Try B for blue, G for green, or something equally easy.Space 6 drops of water (or however many colors you are testing) equally distant on a plate or piece of foil. Position one candy of each color on the drops. Give the color about a minute to come off into the water. Pick up the candy and eat it or throw it away.Dip a toothpick into a color and dab the color onto the pencil dot for that color. Use a clean toothpi ck for each color. Try to keep each dot as small as possible. Allow the filter paper to dry, then go back and add more color to each dot, a total of three times, so you have lots of pigment in each sample.When the paper is dry, fold it in half with the color sample dots on the bottom. Ultimately, you are going to stand this paper up in a salt solution (with the liquid level lower than the dots) and capillary action is going to draw the liquid up the paper, through the dots, and toward the upper edge of the paper. The pigments will become separated as the liquid moves.Prepare the salt solution by mixing 1/8 teaspoon of salt and three cups of water (or 1 cm3 of salt and 1 liter of water) in a clean pitcher or 2-liter bottle. Stir or shake the solution until it is dissolved. This will produce a 1% salt solution.Pour the salt solution into a clean tall glass so that the liquid level is 1/4 (0.5 cm). You want the level to be below the sample dots. You can check this by holding the paper up against the outside of the glass. Pour out a little salt solution if the level is too high. Once the level is correct, stand the filter paper inside the glass, with the dot side down and the edge of the paper wetted by the salt solution.Capillary action will draw the salt solution up the paper. As it passes through the dots, it will begin to separate the dyes. You will notice some candy colors contain more than one dye. The dyes separate because some dyes are more likely to stick to the paper, while other dyes have a higher affinity for the salt water. In paper chromatography, the paper is called the stationary phase and the liquid (salt water) is called the mobile phase.When the salt water is 1/4 (0.5 cm) from the top edge of the paper, remove it from the glass and place it on a clean, flat surface to dry.When the coffee filter is dry, compare the results of chromatography for the different candy colors. Which candies contained the same dyes? These are the candies that have corr esponding bands of color. Which candies contained multiple dyes? These are the candies that had more than one band of color. Can you match any of the colors with the names of the dyes listed on the ingredients for the candies? Further Experimentation: You can try this experiment with markers, food coloring, and powdered drink mixes. You can compare the same color of different candies, too. Do you think the pigments in green MMs and green Skittles are the same? How can you use paper chromatography to find the answer?What do you expect to happen if you use a different type of paper, such as a paper towel or a different brand of coffee filter? How do you explain the results?

Difference Between American And Japanese Horror Essay

Since the early days of filmmaking, Hollywood the dominated over the world cinema. American cinema has always drawn inspiration from other nations. In the past, few countries have received more attention from Hollywood than Japan. There be little doubt that Nakata’s Ringu (1998) has much to do with the recent international interest not just in Japanese cinema, but East Asian cinema more generally. (Colette, 2008). In America and Europe horror films tell the story of extermination of evil spirits, Japanese horror films end up with the suggestion that the spirit still remain at large. That’s because Japanese don’t regard spirits only as enemies, but as being that co-exist with this world of ours. (Suzuki, 2005). In this essay I will look at the difference between American and Japanese horror style and discuss the reasons why Japanese horror films are appealing prospect for remake. To do this I need to look at the importance of Roy lee and vertigo entertainment in r emaking films such as the Ring (2002) which is directed by Gore Verbinski. The difference between Japanese and Hollywood horror is that, Hollywood horror is action-ordinated meaning they rely primarily on blood and violence to scare audience in contrast to Japanese horror which relays firmly on folklore, urban legend, and myth (Langford: 2005: 175) and often offer more depth and thrills.

Comment On An Experience In Your Life That Had An Essay Example For Students

Comment On An Experience In Your Life That Had An Essay Effect On Your Life. I was a little worried writing about my mother because I thought it would seem like I was looking for sympathy, but I figured it was a good topic to write about because it had the largest effect on me. My goal became to write an essay that didnt focus on the death or loss but on the change and growth that took place. Being active is something that has always been important to me, and I learned this from growing up with and observing an expert. My mother was more active and involved than anyone I have ever known. She had an endless energy for life, and love for my two brothers and me, and I have tried to be the kind of person that she was. The phrase on her headstone reads: A joyous and boundless energy. My mother was a highly respected kindergarten teacher for twenty years. In addition to working with children as a professional, she was always involved in my elementary school years, as a class mother or President of the PTO. In the summers there were more children, as we would go to sleepaway camp in Maine and she would be in charge of the youngest group of campers. She was always running, playing, consoling, planning, and caring for children. At home, she was just as active. I remember doing homework with her every night and she got so involved with it that she would practically do it for me, which I thought, at the time, was a pretty good thing. We were always going places, visiting friends, just learning, and there was never a dull moment. Though I didnt know it consciously at the time, she was setting an example which I was bound to follow. Over seven years ago, my mother died after a long battle with melanoma. I was ten at the time, in fifth grade, and I suppose I didnt really understand it all that well, or as well as my older brothers did. This essay is not about that loss or death, but on the change that took place. After she was gone, things were so drastically different, because there was so much dull time with nothing to fill it but thoughts. I think I learned from my mom about how to be active and I must have decided, subconsciously, to continue in her path. I saw how happy she and the rest of my family were, and I wanted to perpetuate that. Though it was a small beginning, I began the next year by becoming class president. I joined every club I could and participated in different sports. I wanted to do as many different things as I could. One of my memories of junior high was being busy every lunch period with meetings: the math team, student government, Junior National Honor Society. I was the this little tiny kid, the smallest in my grade, and I was always running around and talking. I remember being scolded many times for what I thought was having too much energy. I was always taught, by my mother, that energy was a good thing, and when it got me in trouble it was very confusing. I continued with this energy and involvement throughout my high school years. I come from a very small school, and that has had a positive effect in allowing me to explore many different activity options. I wouldnt have been able to experiment the way that I did if I had come from a larger school. I found myself involved in athletics, student government and publications, community service, academic competitions, and drama productions. This experimentation allowed me to see what activities I liked the most, and it gave me a good idea of what I want to continue doing. I loved going to my high school and felt close to the 82 other students in my grade. I think I would like to pursue education at a small school which would allow me to continue to participate the way I have. .u0de55f198498d6a6003f2471baf13b7e , .u0de55f198498d6a6003f2471baf13b7e .postImageUrl , .u0de55f198498d6a6003f2471baf13b7e .centered-text-area { min-height: 80px; position: relative; } .u0de55f198498d6a6003f2471baf13b7e , .u0de55f198498d6a6003f2471baf13b7e:hover , .u0de55f198498d6a6003f2471baf13b7e:visited , .u0de55f198498d6a6003f2471baf13b7e:active { border:0!important; } .u0de55f198498d6a6003f2471baf13b7e .clearfix:after { content: ""; display: table; clear: both; } .u0de55f198498d6a6003f2471baf13b7e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0de55f198498d6a6003f2471baf13b7e:active , .u0de55f198498d6a6003f2471baf13b7e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0de55f198498d6a6003f2471baf13b7e .centered-text-area { width: 100%; position: relative ; } .u0de55f198498d6a6003f2471baf13b7e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0de55f198498d6a6003f2471baf13b7e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0de55f198498d6a6003f2471baf13b7e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0de55f198498d6a6003f2471baf13b7e:hover .ctaButton { background-color: #34495E!important; } .u0de55f198498d6a6003f2471baf13b7e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0de55f198498d6a6003f2471baf13b7e .u0de55f198498d6a6003f2471baf13b7e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0de55f198498d6a6003f2471baf13b7e:after { content: ""; display: block; clear: both; } READ: Patriotism EssayI dont think it really matters to me exactly what I am doing.
