Mixed Lifesaver

Improved Essays
The problem/question investigated was to see if mixing affects the amount of time it takes to dissolve a lifesaver. My hypothesis stated, If a lifesaver is mixed into water then, the time it takes to dissolve will decrease because by stirring or shaking causes the solute particles to separate from one another and spread out quicker among the solvent particles. My hypothesis was supported. For the mixed lifesaver, at 2 minutes 12 seconds, the lifesaver got smaller and turned the water red, at the final time, 9 minutes 25 seconds the lifesaver dissolved in the water completely. For the untouched lifesaver, it’s started getting smaller at 7 minutes 45 seconds and dissolved at 26 minutes 15 seconds. I noticed that the untouched lifesaver sank to

    For this experiment, a few scientists are researching how different flavors/colors of sports drinks effect the amount of red 40 dye in each drink. The independent variable in the experiment is the flavors of Gatorade (a brand of sports drinks) used, while the dependent variable is the concentration of dye the sports drinks contain. The constant variable is the spectrophotometer, the amount of liquid used, and the same type of cuvette. The controlled variable is only using water. In order to determine which drink would have the greatest concentration of red 40 dye, the scientists must first understand what it actually is.…

    Comparisons: Effect of crushed vs. whole tablet: The crushed tablet reacted faster because its surface area is smaller, allowing the particles to react faster with the water. The crushed tablet also produced frothy bubbles all over the water, whereas the reaction (bubbles) of the whole tablet was primarily around the tablet in the water. Temperature effect: The reaction was extremely slow in the cold water as molecules do not move as fast in cold water.…

    Gummy Bear Experiment

    However when our experiment was finished and we fished our gummy bear out of the salt solution, to our surprise there was no correlation between our results. (As shown in the graphs on the next page). There are many reasons for why our results have no correlation (0g and 5g have the highest weights) ,the first would be while we were attempting to extract the gummy gears from their salt water solution many of them broke apart and we had to coffee filter them out which may have cause lots of variation and discrepancy in our data. Second during our process the gummy bears may have diluted into the water as well (this is common problem found during diffusion related experiments). Finally we may have gotten the results we did because of the fact we used table salt for some of our tests and rock salt for the rest ,this was because what was readily available to us a the moment in time and we did not believe it would cause such…

    Environmental Effects on Pillbug Behavior Catherine Liapes October 14, 2015 AP Biology- Pd.9 Mr. Angus Introduction: Before conducting this lab, I researched information on pillbugs and learned that pill bugs are commonly found in damp environments such as piles of leaves, or under logs. Although they are crustaceous, they can still spend their entire lives on land. They are about ¾ inch in length with seven pairs of legs, and multiple antennae. Pillbugs are nocturnal and mainly consume rotting vegetation.…

    11 out of the 36 mixtures were insoluble and because we found this out by solving the Pre-Lab questions when 10 drops on each solution were mixed and a formation of a reaction was formed the chemical for that reaction was estimated to be one of the 11 mixtures with the precipitate colors. In Lab the test tubes that were used was rinsed with distilled water tree times and put into the bin of used test tube. A new thing that was learned in was was the fact that the test tubes were put in to the used test tube bin and not used after the rinse with distilled water. The second very important thing that was learned in lab was if the test tubes aren’t cleaned well enough then there is a high…

    Analysis Of Alka Seltzer

    • 1720 Words
    • 7 Pages

    Introduction: Alka-Seltzer is a medication used to alleviate ailments such as heartburn and acid indigestion1. The ingredients that the tablet is made up of helps explain the name of the medication, the sodium bicarbonate is used to balance stomach acid, help spread the aspirin which allows the speed of absorption to increase, and reacts with citric sodium which produces carbon dioxide2. One initial observation of the Alka-Seltzer tablet and water is that when the tablet was dropped into the water, it began to fizz and make the water look like a carbonated drink such as Sprite. Carbon Dioxide is the gas that humans exhale and what is produced with Alka-Seltzer and water react, the chemical equation of the reaction is, (H2O + C6H8O7 + 3NaHCO3…

    In this unit of my 9th grade Physical Science, we are learning and experiencing with labs. In this week's experiment, my class did the paper towel lab. Here, we tested the quality of three different paper towel brands, Viva, Up&Up, and Bounty. Each lab group was testing for a certain quality of each brand, such as strength and absorbency. Through different experiments, each lab group came to the conclusion that one paper towel brand had more strength or better absorbency than the other two.…

    CONCLUSION: Two weeks ago, Soundings XVI performed Lab Experiment Number Two. Lab Experiment Number Two was similar to the previous, Lab Experiment Number One. The prompt was to compare the results of pennies dropped in water, versus the result of pennies being dropped into milk, both at 100 mL. The main purpose of this lab was to further discuss more scientific parts of this lab, such as the surface tension when the cylinder was close to overflowing for both the milk and water. Before performing this lab, my group and I created a hypothesis to reflect upon and to state what we believed would dictate the results.…

    The question I investigated is if organisms are more attracted to a strawberry then nothing. My hypothesis was "If one cup has a raspberry and the other doesn't" Then The cup with the raspberry will catch more organisms because They want to eat the raspberry so they go into trap number 2. " My hypothesis was correct because I caught ten more organisms the the one with out a lure. After all this research I could come to the conclusion that organisms like raspberry compared to nothing at all. Some evidence from my expire ment that supports the conclusion is that the raspberry caught about 10 organisms while the empty one caught only 1.…

    The purpose of the bath bomb experiment was to examine the fizz by adding extra cornstarch to the bath bomb recipe will affect the overall outcome. If there is more cornstarch added to the bath bomb, then the bath bomb will be less fizzy because cornstarch acts as a dry filler that controls the reaction between baking soda and citric acid. The experiment calls for two different recipes. The first one was the normal recipe which blue was used as the coloring. The other recipe was the extra cornstarch recipe which red was used as the coloring.…
