Conclusion My hypothesis for the penny cleaning with the chemicals experiment was accepted. The hypothesis was; “If a penny is placed in salt and vinegar, then it will get cleaner than the other chemicals being used”. The data used from the experiment that supports the hypothesis was that the salt and vinegar chemical cleaned a penny the best it had a 90 out of 100. A lot of things went well in this experiment. This experiment had the same amount of pennies, chemicals, and bowls to put the chemicals in and the pennies. Another thing that went well was that all the pennies got the same amount of time in each chemical. In this experiment no problems occurred. Some experiments that were thought of doing this this experiment was; What would happen
if instead of pennies use nickels with the same chemicals? Some future research that could be done is; Does changing the chemicals affect the pennies? This experiment applies to real life, because some of these chemicals are used to clean household items. This experiment does not really affect the community. Some things in this experiment could have been improved. One thing is that there could of been more chemicals and pennies involved. Another thing is that there could of been more time spent in the chemicals. One last thing that could of been improved is that instead of using pennies, how about using nickels or dimes for this experiment. At the end of this experiment, salt and vinegar cleaned a penny the best.
The experiment began with Milgram placing an advertisement in the local newspaper to recruit volunteers for his experiment. The experiment began with the introduction of the other participant, the other participant being an ally of Milgram’s. Afterwards, each participant would draw straws to decide which role they would take up, the “teacher” or the “learner.” However, the decision was always fixed so that the participant would always end up being the teacher. The learner would then be strapped to an electric chair by the teacher and would have a list of words read to him to be
A: The reaction with water and vinegar was the most useful in this experiment. The physical properties were very self explanatory because the texture of the powders was all different expect icing sugar and cornstarch. Also the Ph levels were very similar of six and seven for corn starch and icing sugar respectively. d) Q: How confident do you feel about your identification of the
I chose to create a collage dedicated to the short story “Penny in The Dust” because personally, I believe that it was the most impactful short story out of the four short stories that we were expected to read and analyze. “Penny in The Dust” is a brief story about a boy and his father’s struggle to show affection in a traditional manner, which can either be shown physically, or vocally. Throughout the story, the boy, now an adult felt a sense of reminiscence while walking through a field which reminded him of the penny that his father gave him. I chose to do this project in a collage format because, I reckoned that it would have been the best method to show my understanding of the story.
For this lab investigation, our question was do pillbugs prefer vinegar or plain water in their environment? Our hypothesis was that if they were given the choice, then they would choose the water side because their natural environment is not as acidic as vinegar. After we tested this hypothesis, the data that we collected over the course of 20 minutes supported our theory. At the end of the first minute, there were 3 pillbugs on the vinegar side, and 37 pillbugs on the water side. Then, after 10 minutes, there were 4 pillbugs on the vinegar side, 30 pillbugs on the water side and 6 pillbugs that were missing. After 15 minutes, 4 pillbugs were on the vinegar side, 28 were on the water side and 8 were missing. Finally, at the end of the 20th minute, there were 3 pillbugs on
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
My action plan for this experiment will be to test three different methods to determine which will be the best at cleaning a rusty penny. I will observe which methods are most successful at cleaning than the others. The method that works best will be determined based on the results of the method with and without salt.
To prove the two hypothesis the researchers present the participants with a series of opportunities to cheat, but then surprise them with an additional series of cheating opportunities. To increase their interest in participating the contributors obtain $.10 for each flip of a coin, but only if the side up of the coin is “heads”. The participants have the opportunity of flip the coin 7, 10 or 13 times, the flipping of the coin happens privately, and they are told not to cheat. The researches then tried to prove the hypothesis in 4
What would happen if there was not the structure and social rules preventing people from acting on the unconscious parts of thought? I think the experiment suggests that we have the capability and do in fact think of all these possible actions to take, without knowing about it until the thought takes hold and we are compelled to take action (or not act).
First of all, we will talk about what uses we have for the penny. The penny is a U.S. symbol in a way, so there is a comfort with keeping the penny. Most people in this country believe it is a useful coin, presents Joseph Carroll. In fact, most Americans are more likely to pick up a penny off the ground if they find one, rather than leave it (Carroll). By some calculations, rounding sales tax to the nearest penny rather than the nearest nickel (every cent rather than every five cents) saves Americans $1-2 billion per year
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.
Even before i have done the experiment, I am in a position to make a
How important is the penny? How many of the little coins are lost throughout the year? Jim Kolbe, a United States Representative, renders the penny coin useless and even introduced a proposition to congress to rid the U.S. of its smallest coin. The penny is often overlooked by the money hungry economy for bigger and better tribute. There are many people who favor the abolishment of the pesky one cent piece for its considered useless and a waste of time at the register. However, little Lincoln is used in the everyday pricing system, is a historical piece in the nation, and the copper coin, even in its small stature, can bring children hope when given to them for a wish.
There were two rumors in the experiment conducted for the rumor assignment. Both rumors were very different in context but both proved the same thing in the end. Rumor number one was first told to the first individual who was standing outside of the classroom with three other students. Person one listened as the professor said the rumor, and then they had to remember it, and tell the next person (person two) outside the classroom this rumor. The central theme of rumor one was there were two men on the subway who started arguing while many people watched near by.
The first experiment that DeVoe and House (2012) conducted was to directly test their hypothesis. The procedure of this experiment was to take 53 undergraduate students (32 femal...
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.
