Conclusion: Compare Trial 1 and Trial 2. The Trial 1 change in mass are 12.5g, however Trial 2 changes in mass is 1.2g. The Trial 1 change in mass is more than Trial 2. And I think the Low of Conservation of Mass violated in the Trial 1 is can be exist. Because the Trial 1 actually the soda with vinegar have Chemical reactions occur and chemical
The scientists will conduct the experiment by taking four cups of water one that is just salt mixed with water, another that is just water, a third cup that is just ice water and finally a forth cup that is vinegar and water mixed. After that the scientists will drop one Alka-Seltzer tablet into each cup and see how long it takes for it to completely dissolve. The scientists will conduct these three times for
Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
The passing of the Sugar Act further intensified the growing resentment between the colonies and England. George Grenville, the Prime Minister of England, passed the Sugar Act in 1764.This act taxed all of America’s imports. He also more strictly enforced the trade laws. The Americans deeply resented the taxation that they felt was unjust. James Otis put the general mood of the colonists into words when he said each colonist had the right to be “free from all taxes but what he consents to in person, or by his
My experiment is elephant toothpaste were foam shoots out of a container or glass. I chose this experiment because I thought it would be fun to see foam shoot out of a bottle. You get to mix curtain substances together to make elephant toothpaste. I thought if I get a small bottle then the most foam should be produced.
Our experiment consists of adding one tablespoon of baking powder to each two cupcakes. There will be ten cupcakes in all and two will be controls, without baking powder. We will figure out which cupcake is the most “perfect” meaning the most fluffy, its circumference and height will be measured. Baking powder contains sodium bicarbonate, dry acid, and cream of tartar. These ingredients chemically changed out mixture into cupcakes.
We had 3 full trials for the Sprite, but only had one full trial for the water and the corn syrup. To get enough data you need to have a minimum of 3 full trials with similar data. Only one of our experiments had the full three, and that’s why we don’t have enough of the
I’m going to talk about other researcher experiment on “How long would it take to get to the center of the Tootsie Roll Pop”. Also my point of view on what I think about their say on their experiment about “How long would it take to get to the center of the Tootsie Roll Pop”. On the Tootsie Roll web page they had three scientific studies that have attempted to determined on how many licks it take to get to the center of the Tootsie Roll Pop. The first one is from a Purdue University where a “A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center”.
7. In this experiment, if the sucrose concentration were increased to 70 g/l would you expect sucrase activity to be significantly higher than the activity at 35 g/l. Explain your answer. No, because based on the results once it reached 30 g/l 35 g/l the results had stayed the same. There, the activity is lessening and coming to what looks like a plateau. 8.
In our mini-lab yesterday, we put sugar cubes in a jar and shook them for three minutes. The first jar had one cube, the second had two cubes, and the third had three cubes. We were trying to find the impact of the shaking on the sugar cubes. Our sugar cubes represented the rocks, and the shaking was an outside force. My group’s hypothesis was that the sugar cubes would break up.
In this laboratory exercise, I chose one peanut from a bowlful and made "identifying observations" about the peanut. Then placed the peanut back in the bowl and return later to try to find it again by using my observation skills. My hypothesis for this experiment is; if I make careful observations of a peanut, I will be able to identify the peanut at a later time. To prove this hypothesis I wrote down the measurements, weight, and unique characteristics of my original peanut (Color: light yellow-brown, Size: 2.5 cm long, Weight: 3.0 g, Characteristics: 1 wave on top, 2 lumps on the bottom, tip on the left side, curved end). After jotting down my observations I then proceeded to place Peanut #1 into the pile and then tried to find Peanut #1.
Shonda Rhime’s hit show Grey’s Anatomy provides ample opportunity to discuss provocative ideas, both within the world of the show and outside of it by the constant usage of the element music. Rhime’s does her best to illustrate provocative ideas by using the element music as a tool to illustrate certain real life scenes for audience members. Grey’s Anatomy is considered to be one of the most influential television shows of popular culture for various reasons. Grey’s Anatomy is a show that illustrates societal norms and values. The drama filled show tells the story of the doctors of Seattle Grace Hospital who deal with life-or-death consequences on a daily basis.
Then the balloon is lifted up so that the baking soda runs into bottle to react with the vinegar inside. Immediately the balloon is inflated by the carbon dioxide formed. The baking soda is kept constant when the experiment is repeated for another different amount of vinegar. Results/Findings When sodium bicarbonate and vinegar mix,
In the experiment, a magician placed down and shuffled three cups on the table with one cup containing a ball. While the cups were being shuffled,
Conclusion In conclusion my hypothesis was right and the wet bread grew the most (and only) mould. I can logically assume that the more moisture the bread has, the more mould it will grow. This was a fair test because each of the bread pieces had equal time to grow. The End In this experiment the conductor finds out that mould needs moisture thus needs to be included to conduct the experiment.
