Science Experiments Essay

administered to the group. The results from this study suggested that children were able at detecting changes in stimuli of numbers as opposed to letters. Also, change detection, and working memory increased alongside the ages of the children. This experiment gives precedence to the fact that change detection is correlated with age and stimuli type (numbers vs.…

Medical Experiments During the Holocaust Around the time of the Holocaust, physicians and doctors started experimenting on the inmates at concentration camps. These experiments were done without the victim’s consent and sometimes without their knowledge. There were at least 30 different famous experiments done (Seheff, ReduceTheBurden.org). These experiments could result in death, mental distress, or permanent disability. Afterwards, some of the doctors were put on trial. The most well known…

shot at a 45 degree angle and always shot from the lower left corner and what pocket it lands in. Process: I started out by drawing many rectangles with each many different dimensions ( 2*3, 2*1, 4*10, 2*9, etc.) Then i did the actual problem /experiment and counted the rebounds on each rectangle, and each will be shot from the bottom left hand corner.Then when I finished counting the rebounds on each rectangle I made observations on each rectangle to see if there were any rules or…

situations and in even more dire situations. However, this skill can make us miss important information. Previously, many studies that have been done have shown that base rate information is affected with diagnostic information being present. During this experiment, we will also try to replicate the results that previous studies have done in that people will not use logic when presented with diagnostic information The results did show a main effect interaction of the base rate. This finding…

Intriguingly, as the conducted experiments disclose, isobutanol possesses an experimental boiling point approximately 23℃ higher than that of tert-butanol. Additionally, the boiling point of isobutanol appears to be 9℃ higher than that of sec-butanol. The latter had been a surprising, perhaps…

In Mrs. Caushon's Chemistry Class, there are many bright and eager students ready to learn about the wonders of chemistry and the properties of many elements, and in this experiment, the students will be mixing the Metal Sodium with some Water for an interesting chemical reacting, the students we will be focusing on in this story are the two sophomores, Walter Lazee and Jane Dull. "Alright Class!" Mrs. Caushon said in a raised voice. "We are going to be Testing some Chemical reactions today in…

data. The independent variable of this experiment was time, while the dependent variable was the color as the reaction is completely dependent on the duration of time. There were numerous potentially sources of error during this experiment. The seconds between beginning the timer and recording data and the slight overestimation in substance amounts. This experiment could be improved by having precise measurements and using numerous catalysts during the experiment to test the speeds of the…

hypothesized that pill bugs would display a positive hydrotaxis and a negative chemotaxis, but our last experiment supports a reaction to chemotaxis. Since we placed them in a tray with all chemical-filled chambers, we weren’t able to tell if they drift towards diluted solutions because they contained more water. The products of the Chi Square Test told us whether the results of our experiments were significant or not. Our results in Part A and B were significant because the calculations proved…

Researchers are looking into the Closing Time Effect which is the phenomenon that explains the increase in attractiveness throughout the course of a night out. In this study, researchers went to the same Sydney pub on four consecutive nights. They started with a sample of 166 participants that were then narrowed down based on factors in a baseline questionnaire such as drug use that day or an unclear relationship status. As the study was trying to look at this effect as it relates to those in a…

A visual search experiment is an experiment in which an individual's reaction time is tested when finding a visual cue, like a green circle, and determining whether the visual cue is there or not. In the visual field, there also are other objects, called distractors, that aren't the desired visual cue. A subject is tested through two different techniques called a feature search and a conjunctive search. In a feature search, the visual cue would be shown, or possibly not shown, on the screen with…
