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

Prison Experiment Throughout all of history‚ psychological experiments have created controversy throughout the world. A specific example of this argument would be what came from the Stanford Prison Experiment in 1971. This experiment tested whether brutality shown by prison guards was due to sadistic personalities or the environment of the prison (McLeod‚ 2008). This experiment is known for its ethical issues displayed towards the men who were involved in the study. Although this experiment caused

Hypothesis: I think that in this experiment the results of the boiling point of each sample is going be slighly different from what I found on Internet. aim: my aim is to look at what temperature and how long the following alcohol (methanol‚ I-butanol‚ Ethanol and Hexane) reach their boiling point and comparing the results that I found on internet and mine.

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s
