Science Lab Report

INTRODUCTION
Egyptians originally created candles in about the year 3,000 B.C. Even so historians have found out that other early civilizations also came to use the candle by using available plant that had wax in them. One of those countries was China. For most of history, white candles have been used and made, because the ancient civilizations did not have the technology to create red, blue, purple…candles. The major thing that people should understand about colored candles is that the only thing that is added to it to make it colorful is food coloring or dye. Candles consist of wax and a wick. For this experiment the colored and non-colored candles should be the same brand, shape and size.
Have you ever been at home and lit a candle that smells so good? Don’t you hate it when it burns out fast? Or are you one of those people that hate the smell and wants the candle to burn down or else you will shut the thing off yourself? Whatever your opinion is about candles, here you will learn what type of candle you will most likely want to use more. In this experiment what is going to be tested is if white candles burn faster than non-white candles. It is believed that both candles will burn at the same rate, because the only thing that is added to non-white candles is food coloring or dye. There is no apparent reason to believe that colored candles will burn faster, because then that would mean that one candle has more or less substance than the other.
THE PROBLEM
What is the effect of white candles burned compared to non-white ones burned?

HYPOTHESIS
If white candles are the same shape and size as the non-white candles, then they will probably burn at the same rate as each other. This is believed because the only difference will be a color, and according to many resources the way to add color to candles it to melt wax completely and then add drops of dye to the candle and find a mold. Because of this, there it is known that if you have the same type of candle, the rate at which it burn will not be affected because the only thing added affects color not how fast it will burn.
VARIABLES
 The independent variable in this experiment is the non-white candle, because it is not the one typically used in most occasions. The dependant variable in this experiment is the rate that both of the candles burn, because we are to testing to see if the fact that it is colored or not affects the way that it will burn at.
 To measure how fast each of the candles burns it would most likely be most convenient to use a stop watch
 The equipment that is needed is the stop watch to measure the exact time at which is burns at and the candles
 In this experiment the control group is the white candles because as mentioned before they are not typically used. Also the Experimental group is the colored candle because they are not usually use and are the cause for this experiment.
 The variables that will be kept constant in this experiment are the brand,shape and size of the candles, the time at which the candle are lit and the stop watch is started and lastly where the candle is lit.
MATERIALS
 3 white candles
 3 non-white candles ( has to be the same brand, shape and size as the white candle for accurate results)
 1 stop watch
 Matches
 Piece of paper
 Pencil and eraser
PROCEDURE
1) First gather all of your materials
2) Then make sure that what ever base you have for when the candle is lit have something like aluminum paper for the wax. Once wax dries it will be very hard to take out.
3) Aluminum foil is not the most resisting foil in the world, but it can resist large amounts of heat for large amounts of time
4) Take out the white candle and place it on the base which you have prepared
5) Before you light the match on the candle, make sure that your hair is far away form the candle and there is nothing dangling from your hands or else it might catch on fire.
6) Also make sure that the piece of paper is not close to any of the candle that will be lit because it will most likely turn on fire
7) You should also make sure that where ever your candle is it will be safe from any water or air that might turn it off
8) Light the match and set the wick on fire
9) Be carful that the flame of the match does not bend backwards because it might burn you then
10) As you light the wick on fire try to start the stop watch at the same time, it is very important to do so because it could change the whole entire out come of the experiment
11) Make sure that while your candle is burning not to leave the room in case that it burns out and you will have no way of knowing how long took to burn
12) You have to wait until your candle is fully burnt to write down what results you have on your piece of paper or else your results will not be reliable
13) Repeat steps 1-7, 3 times for the white candle and 3 times for the colored candle
14) Three times per candle because this way you have more accurate results because you have tested it more than 2 times
15) Every time that a candle is brunt make sure that you write on the piece of paper how long it took to burn and what type of candle it is.
16) In the end you can compare the data that you have collected and see which type of candle in effect will burn faster
17) Since each type of candle was burnt 3 times then when you finish writing your results, you should make an average to see about how many minutes it total did each candle take to burn down and this will give you a good , accurate and easy to see result
VOCABULARY

Wick- Is a string that is inside of a candle and that holds it up. The wick is also the part that is set on fire in a candle.

Letter to Julia Alvarez

Dear Ms. Julia Alvarez,
In my school we have been reading texts by Hispanic authors and identifying the identity traits and the craft in them. Out of all of those texts that I read I specifically liked yours the most. I think this because you made reading a few pages something worth while and entertaining, and also I found many things that automatically stood out to me as something that has to with me and my identity. And so I am writing this letter to explain how much I enjoyed your story and also talk to you about one, that I found some similarities with. This text is called “Barrio Boy” by Ernesto Galarza and is being compared to one of your stories “Names/Nombres”.
In your text I found one important metaphor that seemed to say a lot about your story. “… they were just being curious I knew, but I burned with shape whenever they singled me out as a “foreigner” a rare, exotic friend”(Page4, paragraph5) .One of the things that I think is most important about this quote is how you feel about being singled for your identity, who you are. Also the way that you write this quote tells me your anger for people who don’t understand who you are and how they make you feel secluded. This quote also has something in common with another metaphor in a story called “Barrio Boy” By Ernesto Galarza. “…off the school grounds we were traded the same insults heard from our elders. On the playground we were sure to be marched up to the principal’s office for calling someone a wop, a chunk, a dago or a greaser…” (Page 5, Paragraph 6). I believe that this quote also has to do with being singled out because it is saying that the most that foreign parents could do was use and teach their children insults. But I do think that unlike your quote this one is harder to understand because of the way that he describes how they insulted each other, like he has no feeling or mood in this story.
Some of the main things that I noticed that were different about your text and Ernesto Galarza’s is that, first of all, your text to me is more about how Latin people can be singled out in others countries. Also I got the feeling that what you were trying to do was to try to explain how we kind of can’t accept others for who we are so we try to fix them to be like us, like when you change some ones name from Julia to Judy. I mostly found this form parts in your text like “How could anybody get Elbures out of that orchestra of sound?”(Page 1, paragraph 1) and “At the hotel my mother was Missus Alburest” (Page1, paragraph 1). On the other hand, Ernesto Galarza’s piece is more about what is expected of immigrants. Like in the quote “Off the school grounds we traded the same insults we heard from our elders. On the playground we were sure to be marched up the principles office for calling someone a wop, a chink, a dago, or a greaser…” (Page 5, paragraph 6), he mentions what words were mentioned in the playground, but what it seems like is that the teachers were already trained to makes immigrant kids go up to the principals office. This all leads me to think that one very main difference that I found in both of your texts is that you want to portray how ones identity is the same as ones name but while reading Ernesto Galarza’s piece I noticed that his is more about explaining his life in school than showing his identity.
Also I would have to say that in your text I found certain quotes that relate to me and what I consider my identity. One of those quotes that I found in your text “Names/Nombres” is ““Say your name in Spanish, oh please say it!” I had made mouth drops one day rattling off my full name, which according to Dominican custom, included my middles names, mother’s and father’s surnames and four generations back…”(Page 3, paragraph 6) One thing that you say here that has to do with my name and how long it is. Being from Spain and Cuba my name is, “Sofia Helena Caraballo Frutos….” And so on. I think that it is very interesting because I know that the scene of “Come on say your full name in Spanish” IS repeated a million times. Also in your text I feel that in your text you have mentioned various times how you pronounce your name and the Dominican rrr. These things make me realize how I take all the things like being Spanish and pronouncing the rrr like an everyday thing without importance. So with your details I realized that to the eyes of others I might be considered exotic because I am different.
All in all, I would have to say that in your story you showed your point about how important identity is to you, but also by not making it too tacky. I believe that when I compare you to the text by Ernesto Galarza, I came to the conclusion that you know how to make a text or a story easy to read but interesting at the same time, and that I could easily feel what you felt in that moment of your life, because of the details that you had added. I hope that we get to read more of your stories in the mere future, because they are easy to enjoy and have a lot to say not only about you, but they can even teach us things of other people’s point of view and lifes. Lastly, I would like to say that one of the first things that I noticed when I was reading your story was how real you made it seem, like when you were embarrassed by your family, and how you might have grown out of them. You really made a story written on paper alive scene for every word, sentence, paragraph and page.
Sincerely,
