develop weaknesses that result in malfunctions or breakages. Corroded metal can also not conduct electricity‚ which again can interfere with the functions of that metal. Aim: the aim of this experiment is to evaluate the effect that sodium chloride has on the rate of corrosion of iron. 1. Experiment 1 2. Hypothesis: An increase in the level of sodium chloride in water will increase the rate of corrosion of an iron nail. 3. The independent variable is the amount of sodium chloride

Purpose The reason for this experiment is to prove that objects of different masses‚ when dropped from the same height‚ fall at the same velocity. Apparatus - 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops

in the 1970s to study the effects of prison conformity on a sample group of college students. This study‚ known as the Stanford Prison Experiment‚ was scheduled to continue for two weeks‚ but it had to be cut short to six days due to the horrendous events that occurred during procedures. Although the majority of researchers currently agree that Zimbardo’s experiment was completely unethical‚ it can be said that the lessons learned from the study are extremely insightful as those lesson continue to

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that

McKimmie of the University of Queensland‚ performed two conformity experiments on university students. These experiments were done too measure the influence of group norms on student ’s attitudes. Experiment one involved 205 university students who rated themselves as being pro-gay law reform. The students were given numerous questions that asked them to rate the moral basis for their attitude‚ and what they believed society ’s attitude was. Following the questioning‚ the participants were told

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
