Potato Experiment Essay

After testing the D. magna with alcohol, the results showed a negative effect on the D. magna. After recording the normal heart rate in beats per minute (bpm) before the experiment, alcohol was applied to four different D. magna for each percentage of alcohol. The three concentrations of alcohol used were 5%, 10%, and 20%. Once the differences in heart rate were recorded for each of the D. magna, the averages of the four differences in heart rate for each concentration of alcohol were calculated…

of feelings and emotions just as we humans do. They experience pain, pleasure, agitation, and even sadness.Just as we suffer, as do they. During experiments, mothers are breed repeatedly and then separated from the young. When pain is evident, the same process that takes place in our bodies, happens in theirs as well. For the duration of the experiment, test subjects are required to be put under an anesthetic. Reports show that at least 10 percent of animals tested on do not receive painkillers…

hypothesis was If we poured the water on the tissue then the thickest one will have the least amount of leakage. Which we had believe that scott would have the least amount of leakage but in order for us to figure that out we has to experiment it. Before we started our experiment I had many questions about tissue who made it, what made them want to event it. I had so many questions so me and my team had came up with a idea to find the history or facts about tissue. So we had found the history…

reaction as well as the time it takes for each change to occur and the temperature at which each reaction occurs. The amount of each reagent used should also be recorded and the expected yield should be calculated as well as the percent yield for the experiment. Then an analysis of the final product using proton NMR as well as IR should be performed to determine the purity of the final product (melting/boiling point can also be used) and if possible any possible side products that may have been…

Of Mice and Men Animals are murdered, tortured, and abused every day, but it is overlooked “in the name of science.” The use of animals for experimentation can be traced back to the second century. The first person known to have performed these experiments was named Galen, also known as “the father of vivisection.” Although, the first writings were believed to have originated from the Greeks, Aristotle and Erasistratus were among the first to perform on living animals. Animal testing is not a…

Animals are used for experiments and tests on a daily basis all around the world. Imagine being a lab rat or any sort of animal and your only purpose is to serve for experiments. The test subjects are being injected by drugs, vaccines and going through endless tests until their life runs out. This is a torturous act on the animals that are used. Is this something that people should allow to continue? Each year over 100 million animals are killed due to experiments and testing, most of them die…

replicate the results of the original are discussed. The independent variable was the verb used in the critical question to describe the collision; one condition would be ‘smashed’ and the other would be ‘bumped’. The dependent variable of the experiment was the speed that the participants estimate the vehicle…

What is a dual task experiment? A dual task experiment is a procedure done in psychology that requires an individual to perform two tasks simultaneously in order to compare a performance based on a single task. In David Strayer and William Johnstons experiment, they performed a dual task study that assessed the effects of cellular phone conversations on performance of a simulated driving task. The purpose of this was to determine if driving while on the phone lead to a failure to detect traffic…

The four experiments performed by Bhalla, M., & Proffitt, D. R. (1999) addressed two main research ideas. The first idea was focused on demonstrating that changes in physiological potential in a variety of contexts affect the conscious awareness of slant. The first 3 experiments showed that conscious slant overestimation is increased by the reduction in physiological potential as a result of (1) carrying a heavy load, (2) becoming fatigued by running, (3) being less physically fit, (4) and/or…

The harmful use of animals in experiments is not only cruel but inhumane. Today we can find more than millions of animals which have grieved in the name of animal testing by undergoing ruthless death. Sun (2012) and Jha (2005) found that around 3 million animals were used annually in experiments. These animals were either killed or subsequently euthanized. Animal testing involves the inflicting distress, pain or even death of animals in the name of medical and academic research. Cohen (1989)…
