This is the process of a cause and effect experimental research test. In a field experiment‚ subjects are observed in their natural outdoor environment so that researchers can study their behavior. Most of the time‚ the subjects are not aware of the researchers and so usually the conclusions are mostly accurate. For example‚ researchers

Animal experimentation‚ also known as animal testing‚ is the use of human substitutes animals for experiments. Experiments on animals began with Greek anatomists. Who are physicians‚ and writers who formed theories on European medicine . During that time doctors had no understanding of the anatomy of humans or any other species. These physicians would perform surgery live on animals to grasp the parts of an animal’s anatomy and their functions. Through the knowledge of dissecting animals many doctors

what many people tend to forget are the millions of animals that are tortured or killed during the process of these painful‚ deadly experiments. Many people seem to misunderstand animal nature and the laboratory procedures and techniques that are executed on the animals. The procedures are cruel‚ unreliable‚ and harmful. I think that the use of animals during experiments should be restricted for‚ many animals are killed or tortured while being tested‚ there are other possible materials that could be

For each variable identified‚ give a specific suggestion for how it can be controlled during the experiment. The independent variable in this experiment will be the time of day that the plant is being watered. The dependent variable will be the plant growth rate. Five variables that should be controlled during the experiment: 1. How much sunlight the

depending on whether or not the five assumptions are taking place. In this experiment‚ students put the Hardy-Weinberg theory to the test. Out of the five assumptions‚ only two were conducted in the experiment‚ Natural Selection and Mutation. For those that do not know‚ the Hardy-Weinberg Equation is used to determine genotype and allele frequencies in a population. After collecting the data from the controlled experiment‚ it is believed that one of the assumptions of the Hardy-Weinberg Equilibrium

If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more accurate and more constant technology. Air resistance would of been a

Limitations Our experiment consisted of numerous limitation and uncontrolled variables which impacted on the validity of the outcome. These limitations include: the lack of repetition resulting in possibilities of outliers‚ inadequate temperature range and limited sample size at each group. The experiment also existed two other uncontrolled variables which are the size of liver and the amount of Hydrogen Peroxide‚ hence altering the authenticity of the practical result. At each of the five experimental

Marion Sims‚ “the father of Gynecology” performed surgical experiments on enslaved African women who were suffering from fistula problems‚ against their will‚ without any anesthesia. That is a very painful procedure to go through with unclean tools and no medicine to ease the pain. Only one out of thirty patients survived. In order to test one of his theories about the
