The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

Kyle Park 11th Grade AP Psychology 09/23/14 Design a Psychology Experiment The topic that I chose for my experiment is very intriguing and fascinating because most people own pets while raising children. It would be interesting to find out if these various pets can help children with their academic studies. Pets‚ such as dogs and cats‚ help children with social skills and interactions with society. Children can learn myriad lessons just from being around domesticated animals. I believe that children

Chem-102 Lab Dr. Sobhi Experiment #3: Spectrophotometric Determination of Tartrazine Purpose The objectives of this lab include- illustrating the use of the spectrophotometer in chemical analysis‚ and generating a standard‚ or calibration curve‚ then using that curve to determine the value of an unknown substance. The spectrophotometer is one of the most powerful tools used in chemistry to find the concentration of substances in solution. It compares the colors of a known and an unknown solution

The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are

In 1963‚ Stanley Milgram‚ a psychologist at Yale University‚ conducted a series of social psychology experiments to study the conditions under which the people are obedient to authorities and personal conscience. The purpose of his experiment was to determine whether or not people were particularly obedient to the higher authority who instructed them to perform various acts even if they violate their own morals and ethics. It was one of the most famous studies of obedience in psychology as it has

The Milgram Study was carried out by Stanley Milgram. Stanley Milgram was working at Yale University as a psychologist. He conducted an experiment focusing on the conflict between obedience to authority and personal conscience. Milgram selected participants for his experiments by advertising his experiment through the newspaper to participate in his study. He chosen men that ranged from the ages of 25 to 50 and chosen 40 men to participate who were unskilled workers. The objective for his experiment

We chose to conduct our social experiment at the Arizona Mills Outlet Shopping Center. Arizona Mills is located in Tempe‚ Arizona. Our experiment was conducted from 4:00 pm to 7:00. We chose this time frame to compare times of less traffic to the times after shoppers get off work. During the experiment the amount of shoppers increased from 1 shopper passing our position per minute to 3 shoppers passing per minute. The increase in shoppers happened close to 6:00 pm. We observed a mixture of social
