INSIDE THIS ISSUE: Bubble Gum by Se Yun 1 Diaper Absorp- tion by Hye Rin 2 Ice Cube Melt- ing by Amira 2 Salt and Egg Floating by Jun 4 Computer Game by Edwin 5 and blowing the gums all on the same day. These proce- dures all helped me really much to make a fair ex- periment and also to keep track of the bubble gums. I think that the feedback that Hayen Kim gave to me helped my experiment a bit because she gave me an idea of lung capacity and also how can I measure the amount of air that people are blowing in. These prob- lems were im- mediately solved when I changed my sample My hypothesis was that Hubba Bubba is capable of blowing the largest bubble. My procedure was to about 10 different types of bubble/ chewing gum and try to blow the bubble with every one of them.My variables are the country that the gum is manufactured in because I think that rich countries will produce better gum. Also, whether the gum is bubble gum or not be- cause I want to see if it matters or not. Last but not least, the quality of the gum because I want to see what makes the quality of the gum good or bad.My sam- ple size is 10 different types of bubble/chewing gum and one person (me) trying to blow them. The reason I chose 10 different types of bubble gums was because I wanted to experiment gums that we could see in our daily life thus types of gums that are popular among people. The reason that I chose to only let one person (me) to blow the bubble was because I had to keep track of air and amount of minute that I chewed. If other peo- ple blew the gum, I can’t measure the amount of air that they are blowing the bubble with thus I also can’t keep track of how good or bad a person is in blowing bubble gums. My hypothesis was supported by my data because Hubba Bubba is capable of blowing the largest bubble. Three things that I did to keep my experiment fair was to chew the gum for a minute before blowing the bubble, using the gum with same sizes, size to only one person doing the whole experiment. In my opinion, I think that giving feedbacks to each other is such an awesome idea be- cause you can share your ideas around the world. Fol- low Up Questions: 1. Will the conclusion change if I used more varieties of people for my experiment? 2. Does blowing a larger gum than others mean that you have larger lung capacity than others? 3. What are some main differences between the chewing gum and the bubble gum?WHAT BRAND OF BUBBLE GUM IS CAPABL E OF BLOWING THE LARGEST BUBBLE?

spoons of salt tofloat an egg. Source of error: First of all, I startedwith the sameamount, and sametemperature of thewater. Secondly, Imeasured theamount of salt per-fectly. Lastly, I usedthe same type of salt(I used a salt that’sreally salty, becauseI thought the weakones couldn’t makethe egg float).Feedback: The
feedback was: Dear Jun Woo,I think that you can add more details in your hypothesis. I
think that different kinds of eggs will have a different amount of salt to float the egg be- cause it can have different weights and the amount of yolk and egg white inside the egg might be different.Feedback from
Denny helped mevery much. It mademe think of a mis-take I made; I usedthe same type ofegg, but I didn’tmeasure if it wasproduced in thesame day, and theegg’s parents; differ-
Hypothesis: I think theegg will float when I put 9spoons of salt.Procedure: First of all, Iwill prepare one cup withnormal water. Next, I willput small amount of saltin the cup and check ifthe egg floated or not. Ifnot, I'll put a little more, and more until the egg floats(When I'm putting the salt in, I will measure by tea-spoons) .Variables: 3 cups of salt ( I think that's enough). Nor-mal tab water.Sample Size: Twice each time (I put the salt in)Question: How muchsalt does it take to floatan egg?Hypothesis: two tablespoons.
Procedure: First of all, Iwill prepare one cup withnormal tab water. Next,I'll start with 6 tablespoon. Then I'll check if the egg floated or not. Afterthat, I'll put 8 table spoon, then add 2 more table spoon(on and on until the egg floats).Variables: 1 1/2 cup of normal tap water. One egg (notboiled) [I put this amount of water, because I thought itwas just enough for this experiment – I thought toomuch water would take a large amount of salt].Sample Size: 2 tablespoons of salt every timeI put it [I thought puttingone table spoon wouldn’treally make the egg float,so I decided to put 2 ta-ble spoons every time Iput them].
Conclusion: My hy-pothesis was not supported by my data, I thought itwould be enough to float an egg by putting 9 spoons ofsalt in table spoon, but I was wrong. I needed 13 table
ent type of chickens.
Follow up ques-tion:
-Does the tempera-ture of the water ef-fects an egg float-ing?-Will different typesof salt change theresult?-Will the type of cupor a container thatcontains the watereffect the result?
