The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

The Tuskegee Experiment In 1932‚ in the area surrounding Tuskegee‚ Macon County‚ Alabama‚ the United States Public Health Service (PHS) and the Rosenwald Foundation began a survey and small treatment program for African-Americans with syphilis. Within a few months‚ the deepening depression‚ the lack of funds from the foundation‚ and the large number of untreated cases provied the government’s reseachers with what seemed to be an unprecedented opportunity to study a seemingly almost

Title: An investigation into the impact of group pressure on an individual’s estimate of the amount of beads in a pot (ginger granules in a jar). IV = Group/Individual DV = Individual beads estimate Abstract This experiment investigated the impact of group pressure on the individual. The hypothesis is that group pressure does indeed impact on the individual and in this case the individual’s estimate of the number of ginger granules in a jar. Participants were asked to make a judgement of

In the sixteenth and seventeenth centaury in Europe there were was a scientific triumph that led to insight and new information of astronomy. Scientist such as Copernicus‚ Kepler‚ Galileo‚ and newton questioned the scientific methods of Ptolemy and Aristotle. These scientists changed the beliefs of their followers to create a more modern way of life. In the sixteenth century‚ the beliefs of Aristotelian-Ptolemaic were accepted by society. The geocentric theory was one of many that was created
