All students have to take exams at some point in their schooling careers and often in overwhelming amounts. With tests carrying great importance, students try to optimize their performance on these tests in a variety of ways. A widely-practiced strategy is eating peppermint or candy during the test in hopes of boosting brain performance. Peppermint has been known to stimulate olfactory receptors in humans. Similarly, acidity is an alternative powerful taste stimulant. Although acidity stimulates taste receptors and not olfactory receptors, taste and smell are very closely related which makes peppermint and acidity have similar overall effects. Since peppermint has shown improved memory and cognition in students, this study will now examine how acidity effects brain performance. This inquiry was investigated by giving 84 local high school students beverages of ranging acidity levels and soon after having them complete a timed, four-function math exam to test their brain performance. With average test scores of 38.62, 36.05, and 40.02 for the highest acidity, medium acidity, and lowest acidity beverage respectively with a control (no drink) average of 39.33, acidity does not appear to have an effect on student brain stimulation (p=.53). In conclusion, there was no statistically significant correlation between acidity and student brain function, but this was only a preliminary study and similar concepts should be further explored in the future.
Maple syrup has been identified as one of the healthiest natural sweeteners by many scholarly sources. Previous research has examined the bacteria growth in syrup samples to assess its antibacterial properties. The goal of this research study was to examine the bacteria presence on locally versus commercially produced maple syrup in Geauga County, where home produced maple syrup options are prevalent. To assess the differences in terms of bacteria growth and sugar content of syrup samples in Northeast Ohio, a quantitative method was conducted where five samples from roadside stands and five samples from mass produced locations sold in stores were purchased. The colonies were counted over a period of six days and the sugar content was measured using a refractometer. It was concluded from this research that home produced samples contained less bacteria than store bought samples, which indicates potential health benefits for consumers to choose the best source of maple syrup production for their health. There was also a slight correlation discovered between the sugar content of the syrup and the number of colonies grown by the end of the data collection period.
Arabidopsis thaliana ecotype Col-0, a model organism in plant physiology, was studied in conjunction with heat wave temperature patterns, here defined as a multi-day pattern of oscillating high maximum daily temperatures and normal temperatures. The study was run with an experimental design, involving the construction of two plant growth chambers, of which one was set to maintain a constant temperature around 23º Celsius. The other was set to vary in maximum temperature according to a heat wave definition based upon climate data from Columbia, Missouri, the native region of the studied ecotype of A. thaliana. Seeds were placed on fertilized soil and watered daily throughout the process of their growth, and they were moved into the growth chambers after sprouting under sunlight. Data was collected regarding each plant's developmental stage throughout plant growth, and biomass data was collected at the end of each individual's growth. Overall, an effect on the plants was found when the control and experimental groups were compared. The experimental group showed increased plant mortality and slowed plant development. This study has implications for the field of environmental science, climate research, and biology in that it may impact both the study of plant growth and planting seasons in agriculture. These results suggest potential for future studies into the genetic differences between plants that thrive under each set of conditions. These results are in agreement with other evidence of the negative effects of climate change on ecosystems.
Music with a mood that does not match the movie scene is a form of film music that has been experimented with and explored over time. It has been recognized to have varying effects on audiences, specifically on mental processes like perceptions and moral judgment. One goal of this research was to explore a more underexplored aspect of this kind of film music: the emotions of the audience. Furthermore, the main goal was to determine if music with a mood opposite to the movie scene would convey and amplify emotions of the audience. To study how emotions of audiences are impacted by music with a mood that does not match the mood of the movie scene, multiple clips from movies with either music that matched or mismatched their original scenes were chosen to have new music edited onto them. This led to two groups: matched and mismatched mood clips. From this point, a survey with questions about emotions felt per each clip was distributed to participants, who watched the clips live. After participants responded about emotions that they felt and the intensities of those emotions, their results were analyzed to determine that music with a mood opposite to the movie scene does amplify the emotions of the audience and can convey new emotions, though results for newly conveyed emotions varied from clip to clip.
This experiment was conducted for the purpose of inquiring how the concentration of antibiotics, specifically Amoxicillin and Cephalexin, would affect the productivity of aquatic microorganisms within Northeastern Ohio rivers. In acknowledgment of the growing concerns over agricultural pollution, the study was devised to increase current knowledge of how the presence of antibiotics could affect aquatic microorganisms other the well-documented creation of antibiotic-resistant bacteria. In order to achieve the research goal, water was collected from a Northeastern Ohio river and then tested with various amounts of antibiotics. Over the following five days, the concentration of dissolved oxygen was measured which was used to calculate the overall rate of respiration of the sample. The overall respiration rates of the samples with Amoxicillin were 0.0369 mg/L·hr (milligram per liter per hour) with no antibiotics, 0.835 mg/L·hr with 250 mg, 1.16 mg/L·hr with 500 mg, and 0.951 mg/L·hr with 750 mg. The samples with Cephalexin yielded rates of 0.963 mg/L·hr with 250 mg, 0. mg/L·hr with 500 mg, mg/L·hr with 750 mg. These yielded R-values of 0.694 and 0.788 respectively.. This means that the null hypothesis was rejected, thus showing a statistically significant correlation. However, the alternate hypothesis was not supported as a positive correlation between the respiration rate and antibiotic concentration was shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
