Since the experiment procedure did not specify how much activated carbon should be added, too much activated carbon was added. This can lead to systemic errors because there was so much activated carbon on the top of funnel that won’t even wash off, which might had came back as contaminates
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 hypothesis made, the density calculated in the experiment will stay the same because the density of the unidentified object will never change, was supported. The results support the hypothesis because in every trial the density always came out to 9g/mL. In trial one the mass was 71.16g, the volume was 8mL, and the density was 8.895g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial two the mass was 71.12g, the volume was 8mL, and the density was 8.89g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial three the mass was 71.14g, the volume was 8mL, and the density was 8.8925g/mL, but when rounded to the proper sig fig came out to 9g/mL. When averaged the mass was 71.14g, the volume was 8mL, and the density was 9g/mL. Errors that could have occurred are, not calculating the density correctly, not completely submerging the unidentified object with water in the graduated cylinder to get the volume, not rounding the sig figs correctly when finding the density, not measuring the unidentified object’s mass in grams, not measuring the unidentified object’s volume in milliliters, and not writing the correct units with the proper number or not the correct unit at all.
In this lab, we soaked a gummy bear in water for twenty four hours to see the effects osmosis would have on it. When we got our gummy bear we would take its measurements and soak it in water. After twenty four hours we would take it out and record the measurements again and find the percent change. The question that we addressed in this lab was, what would happen if you soaked a gummy bear in water for twenty four hours? I hypothesized that after this time the gummy bear would increase in size.
Data Analysis Does the mass of a pinewood derby car affect the speed? If the mass of a pinewood derby car affects speed then the more mass the car has, the faster it will go. The procedures for the experiment were; Go get a pinewood derby track, car, scotch tape, quarters, and a timer. Set up the track. Make the derby car with the instructions included with the kit.
This attempts to explain that the gum is bursting with flavor and is why you should chose this over other types of fruit
3. In this experiment, the percent yield was 90%. This number implies that there was little error in this experiment. However, this result could have been caused by certain external factors.
Between days one and two the difference in mass of the gummy bear was increased by 5.9 grams, having about a 169% increase in mass. (#2) Similarly, the volume of the gummy bear increased by 7.374 cm3 having a 246% increase after soaking in the
The authors attempt to determine the cause for this discrepancy
You Gotta Believe (YGB) is an organization that tries to find permanent parents and families for young adults, teens and pre-teens who are in the faster care system. Being a one of a kind organization in the New York City Metro area, YGB focuses on finding homes for youth age 10 and up, especially those age 16-21. With more than 400,000 children in the foster care system in the U.S. YGB, believes that every child deserves to be part of a stable and loving family. Adoptive parents receive tremendous support from YGB through classes, group meetings and coaching. YGB provides support before the adoptive process, during the process and after the adoption has been finalized.
In this lab, human error could have possibly been that the salt wasn’t fully dissolved or even the Kool-Aid wasn’t fully dissolved. To fix this next time, both mixtures can be stirred a little longer. A third human error could have been when putting 20 drops into the test tubes, some drops were bigger than others causing there to be more than mL of mixture in the test tube. At the end of the lab, a red and yellow M&M were used to do a home material test. I dissolved the color off the shell with warm water and placed a dot of each color onto a strip of chromatograph and placed them in two individual
Some ways to improve the lab are to make sure that the error sources are fixed. Next time, it should be imperative that the table being used is perfectly balanced and that the tape is not placed on the inside
All the experiment was depending on fortune and luck and can not be successful at all because the performers do not have proper direction to perform the experiment. For the experiment, workers should have proper equipment, standardise and should have power to do work their own way. It is also concluded that the quality of production might be great in future by use the present statics and create a quality control chart and solve the problem in specific problems which effects the project. The common wisdom is that if only people did not make so many mistakes, there would not be so many problems. But even with the variation contributed by the people reduced to zero, there are still too many red
Morgan Spurlock did this experiment because two overweight girls were sewing the Mcdonald 's fast food restaurant for making them obese. The girls lost the case because they couldn’t prove that Mcdonald’s food made them obese. Morgan did this experiment to prove if Mcdonald’s food did have an effect on your health after eating only Mcdonald 's. During the experiment Morgan had to follow rules and guidelines. Rule #1 is that when only when asked Morgan must eat Super Sized Meals.
A common debate of the classroom is whether students could chew gum in class. As it turns out, research shows that chewing gum has many positive effects. Students should chew gum because of all the positive benefits. Some benefits of chewing gum are calmed appetites and more concentration. Chewing gum also releases stress.
