Conclusion When given a blind test does the substitution of a banana for an egg in a recipe make the dish taste the same? In the experiment five foods were made and each one of them had regular version and a substituted version. The substitution was about a banana for an egg. Then ten people tasted both foods in a blind test and were asked a series of questions. In the end 48 of the 50 comparisons were correct in guessing the correct dish. The experiment could have gone many ways with different possible results. There are a couple of changes that might be made to make the experiment better. One change would be to use something else instead of bananas for eggs. Bananas have a strong flavor, so maybe using applesauce for oil or avocado for
The experiment was not a success, there was percent yield of 1,423%. With a percent yield that is relatively high at 1,423% did not conclude a successful experiment, because impurities added to the mass of the actual product. There were many errors in this lab due to the product being transferred on numerous occasions as well, as spillage and splattering of the solution. Overall, learning how to take one product and chemically create something else as well as how working with others effectively turned out to be a
A sample of children ranging from 4 to 13 years old are going to be asked to watch a Rainbow Brite video. The children will be randomly picked from a childcare center. To ensure that the children are going to be randomly assigned, the children will range in different age groups. The first group will consist of 4, 6, and 8 year olds. The second group will consist of 10,12, and 14 year olds. It would have to be a field experiment because you have to go out and collect the data.
As the hypothesis states the consumption of hot salsa causes sweat to occur, due to an increase in body temperature, experimenting using a different brand or type of salsa containing a greater amount of heat or spice would be effective, as a great extent of spice would support the stated hypothesis and would result in a higher increase in body temperature. Other logical and more effectual aspects of the experiment which can be altered would include, the portions and amounts of mild and hot salsa which are provided throughout the experiment. Altering the portions and amounts of mild and hot salsa given to more massive and larger servings would result in a successful experiment, as the object or motive of the lab is to identify if the stated hypothesis is accurate and

Another error could have been with the short amount of time we were given we could have not allowed the experiment to develop all the way. A lot of possibilities could have happened if we left the dead yeast in the incubator. The amount of carbon dioxide produced could have dramatically increased or decreased. If we would have more time we would have been able to collect more data, but at least we had enough. One last error that could have happened was that the logger pro on the computer might have gave us false data or something happened with the system that would result it to malfunction. An experiment we could conduct do to this experiment is we could have 2 beakers containing the same substances that were involved in this experiment. Then we could leave one beaker out and the other in the incubator. This could result in us asking, does temperature affect the amount of carbon dioxide that is being produced by dead
Fair test: To make this experiment a fair test, I will set out a table
The research our experiment was founded on was that carried out by Taylor and Faust (1952). They carried out an experiment on 105 student’s, which was designed in the method of the game ‘twenty questions’. The students were split into teams of one member, two members and four members. They were then told that the experimenter would keep an object in mind whether it is animal vegetable or mineral was also stated, and they were then allowed 20 questions and guesses to reveal the identity of the object. In there experiment they found that the group of two members performed better than the group of four members in terms of how many guesses and questions it took them and how long it took them to deduce the identity of the object. However Taylor and Faust found that the efficiency did not differ in any significant way.
The experiment was mostly successful because the results were as they were referred on the table. The directions were followed completely as was listed on the board. The instructions were easy enough to follow and perform. There was a list of five tests that were to be done. The indole test was easy to perform and there was no color change on the card. The second test was the Citrate test and the results turned a beautiful blue color in the tube, which showed the results were positive. The Methyl red test was a yellow orange color, which was a negative result. If it was positive it would have turned red color. The Voges Proskauer test resulted in a beige color, which was also showed negative. When looking up the organism E. aerogenes it listed
There is also a small standard error of the mean compared to the size of the standard deviation which indicates some uncertainty in the accuracy of the results. The concentrated solutions used may have been contaminated from the source and therefore all collaborated results would be inaccurate due to the solutions not being of the correct percentage concentration of sodium chloride. The results would be inaccurate as they would not be correctly collaborated to the correct concentration in which they are being graphed for. Another systematic error is that the eggs are not all exactly the same size and effects such as surface area to volume ratio can impact how much water enters or exits the egg at any point in time. There was also still traces of shell left on some eggs which would have affected the rate of osmosis as not all membrane was available to be utilised in the diffusion of water. However, a larger sample size will eliminate the effect of this error. The reaction may have not reached equilibrium in the time frame of 10 minutes and this may be needing to be extended. For an equilibrium to be reached between the water and solute in the egg and in the solution. The strength of the experiment included the efficiency in which the practical was completed placing 2 eggs within a solution each at the one time as well as collaborating results with other experimenters in order to achieve an average overall for a larger sample size. Yet it could still be improved by further increasing the sample size of the experiment to counteract and possibly eliminate the effects of errors on the
To answer the hypothesis the scientists used 5 reagents to test for known nutrients in specific types of food. These five reagents were used to test for proteins, vitamin c, starch, chloride, and simple sugars. Then the ten foods were put in to a food processor with water to become a paste. Ten test tubes were labeled with the name of each food. After that the reagents were added to each test tube of food. To test for fat the food
The experiment’s purpose was to determine whether the rate of reaction was impacted by reactant concentration or temperature. Based on scientific research, it was said that if the reactant concentration was increased, then the rate of reaction would also increase. Also, if the reactant temperature was increased, it was believed the rate of reaction would increase as well due to the increased kinetic energy and speed of the molecules. Based on the results, my first hypothesis was not true. The reaction with the lowest concentration of pea extract had the fastest rate of reaction, while the highest concentrated pea extract finished second. The second hypothesis was found to be both true and false because the warmest temperature reaction
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
Our independent variable is one piece of the type of chewing gum we will be giving each of our test groups: flavorless, mint, or fruit flavor are the three types. We are using three different flavors of chewing gum, including one with no flavor, to see if the increase in intellect has anything to do with the taste of the gum rather than just the movement of the jaw. We will use the results of each flavour to see if maybe a certain flavor s...
All the students were asked permission to use their photograph in the study being done. The students being used had glasses or normal eye sight and had no neurological disorders. The participants had gone through two neurological testing to screen them and see their ability to recognize unfamiliar faces. Once the screening was done there was 44 of the participants who where part of the control group, all the participants had no problem with recognizing unfamiliar faces. Whereas the 14 other participants were the group who had seem to have the most difficulty with recognizing unfamiliar faces. They would be the ones whose scores would be tested more thoroughly.
