carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head

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

Matthew J. Hornsey; Louise Majkut; Deborah J. Terry and Blake M. 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

The Tuskegee Syphilis Experiment The Tuskegee Syphilis Experiment took place in Macon County between the years 1932 and 1972. The U.S. Public Health Services teamed up with Tuskegee University to study how syphilis would advance when left untreated. A total of 600 African American were joined in the study‚ out of these men 399 were diseased before the study began and 201 did not have the ailment. All the participants were uninformed of what they were actually being treated for. According to the

decreased with time. This happened because the difference in water potential between the inside and the outside of the beetroot time decreased as the experiment proceeded. Osmosis occurred most in distilled water because this contained the highest water potential when compared with the other beakers. Five concentration were used in this experiment in an attempt to try to find the concentration of sugar inside the beetroot. If such concentration was used there would have been neither a decrease an

Experiment: The purpose of this experiment was to test which variables affected the horses sympathetic nervous system leading the horse to stress and drooling. There were multiple variables tested such as the dilation of the horses eyes‚ if the horses ears were up and lastly if the horse drooled. In order to conduct this experiment‚ we had one horse getting honked at by a car and then testing those variables to
