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 purpose of this experiment was to identify which brand of mint gum holds its flavor the longest. The four brands I chose were Orbit, Trident, Ice Breakers, and Wrigley's Doublemint My hypothesis was that Trident brand would last the longest and Wrigley's Doublemint would last the shortest. I did not use any people in my test. I chewed the same amount of gum at a time and the gum was all the same flavor, mint. All the gum was bought at the same time from the same store. I chewed the four brands of gums between periods of time. When chewing, I timed myself with a stopwatch. When I believed the gum ran out of flavor, I stopped the timmer and recorded the time. My hypothesis was incorrect. Instead of Trident, Orbit lasted the longest. However
The first thing I needed to see was how different concentrations affected the weight and length of the potato. So I needed to see each extreme - highest concentration and lowest concentration. I used 0 molar concentrations (the lowest) and 1 molar (the highest.) I then left each test for 20 minutes, but found after that time a slight reaction had taken place - the potato chips only increased or decreased by a very short amount. I then predicted that now I would have to leave the tests for a longer amount of time and use longer potato chips to ensure that there is enough of a reaction to compare
The scientist determined how much caffeine, and sugar was in each liquid. In order from least to greatest dealing with the amount of sugar in each liquid, is Coffee, V8 Splash Tropical Blend, Arnold Palmer, then Coca Cola. From least to greatest dealing with caffeine is Coca Cola, V8 Splash Tropical Blend, Arnold Palmer, then Coffee. As a result, the scientist believes that if the different liquids are placed in different cups with the eggs, and left for a week, then the Coffee will have the biggest effect on the eggs, because it has the most caffeine and sugar. To test this hypothesis, the scientist will start by pouring four ounces of each liquid into four different cups, and an egg in each cup. The scientist will check on the eggs every day for one week to observe and collect any noticeable changes on the eggs. The scientist will then record our data in our lab
In this observation project the results will show and discuss that of a natural observation. When presented with a choice of a snack, such as a healthy option or unhealthy option what will most people choose? In the second half of this observation, A variable will be added in order to change the behavior.
I blended on high to make the potatoes more liquid-like. I grabbed the cheesecloth and placed on the top of the blender. I poured the potato extract on the container and labeled it. I found out that I have to make 1% sugar solution so I grabbed the sugar and measured into 5 grams on the scale. I added 5 grams of sugar on 250 ml graduated cylinder and poured the water into the cylinder. I mixed the sugar with water and poured it into the saucepan. I refilled the water into the graduated cylinder and poured into the saucepan. I turned on the heat of the stove and saw the sugar dissolved. I poured into a container and labeled 1% sugar solution. I repeated the same thing with 1% salt solution by using 1 gram of salt and filled the water into graduated cylinder by 100 ml. I answered question three. In the first experiment, I grabbed four transfer pipets and used it to put solutions into the test tubes by 3ml. I labeled it and placed into the plastic cups so it can stand upright. I grabbed each test tube and poured 2 ml of catalase solution into it. I also tapped and swirled to measure the bubbles by using the ruler. I wrote the numbers into the lab report. In the second experiment, I labeled the room
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
This experiment determined what temperature and what type of chemical had the most effect on the membrane of a beet. It was hypothesized that if the beet was put in a higher temperature, then it would have harm the membrane therefore releasing the most pigment into the water, rather than a cooler temperature. This was predicted because when a substance or particle is placed in a cold temperature, the process slows down and when it out in a warmer temperature the process speeds up. For the different chemicals, it was hypothesized that when the beet was put in acetone, it would release the most pigments because it was the most acidic chemical; if it's strong enough to take off a chemical like nail polish then it would break the membrane of the beet. The hand soap was thought to have the least effect on the membrane of the beet because its acidity was a little higher
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.
Showing from trial to trial what would occur if different quantities of lemon drops impacted the mass of the curd. Therefore, the hypothesis was supported because different amounts of lemon drops did alter the mass of the curd. With some having a heavier density than other trials performed. As used, in the 1st and 3rd trial, more lemon added impacted the mass from the curd by increasing its mass by 1.3 grams. Since lemon has a higher saturated concentration with the saturated fat from the milk its mass could well be varied upon on, which is why adding more or less lemon drops does effect the mass of the
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...
In conclusion, the method seems flawed in accurately measuring the glucose concentration of solutions. To make the experiment a "fair test," three main variables needed to be kept constant. Firstly, the volumes, including all measurements, i.e., the amount of Benedict's solution used and the amount of glucose water solution in each test tube. Secondly, the time that all the test tubes were kept in the water bath had to be the same for all test tubes, including solution X.
In five of the ten choice pairs, one option would be healthy and the other would be junk food (e.g., apples or brownie). Participants would be told that they would receive one of the items they chose, making their choice more consequential. Those in the audience present condition would read that the other participants in the study would have access to their choices and would be asked to form impressions about them based on the choices they made. This would not be true for those in the audience absent condition, who would be making their choices in isolation. The main DV of interest in this study is the total number of junk food items each participant
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
A third of the way through the experiment a problem was encountered. One of the subjects got sick and was only able to provide feedback on the Peppermint lip balm. The experiment than switched over to another subject who completed feedback on the two other lip balms. Another problem that was encountered, was that one of the subjects did not like the
