Nuclear Fission


My project was about the topic of Nuclear Fission, and how its power can be used to generate electricity. I think this is a great form of energy because it does not emit any CO2 gas and can make lots of power. At the beginning of my paper, I wrote about how nuclear energy is great for the environment and how nuclear fission makes it work. I then talked about my experiment and what I would be doing. The next part shows my hypothesis, where I predict what will happen in my experiment. I then have the procedure for the experiment to show how it  was completed. After that, there is the data section that shows tables of my 3 trials and a video of what it looked like. Then I have the analysis portion, which shows my data on a graph. Finally, I have my conclusion. From this project, I learned how to conduct research and perform experiments in the best way.

Can Fast Food Logos Influence Peoples’ Choices in the Places They Choose to Eat? A Quantitative Study.


This quantitative study was done to investigate if Logo influences customers to buy food or choose a fast food restaurant over another. The sample of this study consisted of 100 high school students. The researcher used two pictures of a hamburger and see which image the students will choose. The results demonstrated that 79% of high school students choose the elaborate picture of the hamburger over the simple hamburger picture.

How to Reduce the Amount of Debris in Space


The purpose of this project was to find the most efficient way to extract space debris from earth’s atmosphere. Initially, the hypothesis was that if using a man-made net to extract space debris from a model earth, then the net will extract more pieces of debris than a harpoon can. To find if this was true or not, I created a model earth and stuck toothpicks into it that had pieces of aluminum foil attached. Then, there were two extraction devices made, a harpoon gun and a net. Next, there were 5 trials of each device given 30 seconds to see how many pieces they could extract. With the harpoon gun, the average number of metal pieces picked up was 28.2. All data was higher than the net. For the net, the average was 19.2 and was significantly lower than the harpoon gun. This is the data that was collected. Altogether, the hypothesis was unsupported, but a better way to extract space debris was detected. This information could be applied to scientists when they attempt to extract space debris.

Does the application of UV light decrease bacteria growth?

Recently my teacher sent me an article that stated research was being conducted to see if ultraviolet light could be used to kill Covid-19 viruses. I wanted to test for myself if UV light could be used to slow or stop bacterial growth. To start the experiment we got nine petri dishes and divided them into the three groups, control, UV, and UV and hand sanitiser. I poured melted agar into each petri dish, and then we waited for them to solidify. I then collected bacteria, on a cotton swab, from a door knob and streaked all of the petri dishes. I then streaked the petri dishes that had Uv light and hand sanitiser with seventy percent alcohol hand sanitiser. For the UV and UV and hand sanitizer combined petri dishes I put them in a UV chamber for five minutes each. I then sealed all of the petri dishes with clear scotch tape to eliminate the possibility of possible pathogen exposure. After that I took all the petri dishes to my house and put them in a safe and stable environment, so that they would not be accidentally tampered with and so they would stay the same temperature. When they were all in the safe and stable environment I took pictures of all them so that I could compare the bacterial growth after two weeks.

Food Coloring


This experiment investigates and analyzes the chemical compounds of natural versus artificial dyes and determines whether or not there is a difference in benefits. The effectiveness of the food colorings will be tested by being diluted in a saltwater solution. The food dye is projected to sit in the solution for 30 seconds. Food-coloring molecules are ionic solids that contain ionic bonds. The experiment will effectively analyze which ionic bonds release dye the quickest and boldest.

Appropriation of African American Culture in Disney Animated Films

Over the past 30 years racial representation amongst Disney animated films have changed significantly, becoming more inclusive and diverse. This study aims to understand the cultural accuracies and inaccuracies in Disney’s proclaimed diversification of its animated films. Using the Research of Colin Roedl, Jennifer Barker, Richard Breaux, Megan Condis, Zelda and Sarita Gregory, this project aims to “dig a little deeper” in African American representation in Disney Animated films. Specifically looking at The Princess and the Frog, Soul, and Spies in Disguise. This study aims to answer, “Are African American Leads the Film's Protagonist as promoted, or do they lose focus after turning into an animal? This will be done close examination of the Disney Animated films featuring an African American lead stated above.

Aerodynamics of Paper Airplanes

The purpose of my experiment was to determine whether the length of a paper airplane's wingspan affects its travel distance. The hypothesis was If the airplane's wing is more extended, then the airplane will fly further. To test this hypothesis, 3 different paper airplanes were designed with different wings lengths. Each paper airplane was thrown 5 different times indoors to eliminate the wind factor. The mean of the data would be calculated and then the data would be compared. Paper airplane design one had a wingspan of 3 5/16 inches and had an average travel distance of 608.99 cm. The third paper airplane design had a wingspan of 3 7/16 and an average distance of 945.49 cm. After finishing the experiment I was able to infer that the longer the wingspan the longer the paper airplane is able to fly. The next step in this experiment would be to determine whether a propeller or gliding wooden airplane flies further.

Mother-Daughter Relationships

My original hypothesis was that the disconnect is affected by each person's perception, the type of relationship, and the depth/conservativeness of the conversations. The disconnect may be caused by how each individual interprets what the other is saying. Investigating why daughters blame their parents for their mistakes and everything wrong in their lives revealed that parents aren't the only culprits; social media and peer pressure also play a role. It is critical that mothers and daughters do not try to emulate or compare themselves to the mother-daughter relationships depicted in films.With the rise in mental health issues and the popularity of the terms "daddy issues" and "mommy issues" in the media, it is critical to genuinely evaluate mother-daughter relationships in order to bring both parties to some sort of agreement on their relationship, which could heal it. The research gap is in determining what characteristics make a relationship range on a very unhealthy to very healthy Likert Scale. These responses aided in determining the type of relationship that has the most/least/most impact on the daughter and the disconnect (prove it is depth of conversation). ​

An Investigation of the Relationship Between Salinity, Specific Heat Capacity, and Boiling Point


The main aim of this experiment was to investigate the relationship between salinity, specific heat capacity, and boiling point of water. The hypothesis was if salinity increases, then the specific heat capacity would decrease, and the boiling point would increase and vice versa. The assumption was proved correct. The R-squared found for the specific heat capacity vs. salinity was 0.895, and the slope-intercept was y=-0.376x+4.16, symbolizing that increase in salinity leads to a decrease in the specific heat capacity as a negative slope emphasizes the inverse correlation. For boiling point vs. salinity, R-squared was 0.998, and the equation was y=9.52E-03*x + 100, which shows a positive slope meaning the two variables are positively related. For boiling point vs. salinity, R-squared had the closest values to the line of best fit because it was not observed but calculated. The average cooking time for pasta vs. boiling point had an R-squared of 0.819, and the slope-intercept form was y=-44*x + 4930, which shows a negative correlation. The experiment proved that water with high salt concentration would boil quicker and cook pasta faster. Yet, to observe a significant difference in the boiling point of water and pasta, the salinity had to be enormous. Cooking with such a high salinity would ruin the pasta. Therefore, in cooking, the two properties would not affect the cooking time by much since the salt concentration is too low, making it indifferent whether people add salt or not.

Which grade level works better under pressure, Tenth or Eleventh graders? A Quantitative Study of Which Students Work Better When Put Under Mental Pressure.
The researcher wanted to conduct a quantitative study to test both 10th and 11th graders to find out which students will work better under pressure. The sample of this study consisted of 109 high school students. The students took an online test to evaluate how students work under pressure. The students had to answer 25 multiplication exercises in six seconds. According to the data analysis, the 10th graders worked better under pressure than the 11th graders.

Microplastics

This lab explores the best way to filter microplastics that are found in rainwater. It compares how well a manufactured filter cleans the water to how distillation performs. I hypothesize the best filter to use is the process of distillation. However, while conducting the experiment I found different results. Before testing, the rainwater was not drinkable. After filtering the rainwater through the distillation process, it was 70% drinkable, 45% clean and 1% of microplastics were found. While after filtering the rainwater through the manufactured filter it was 80% drinkable, 60% clean and no microplastics were found. This meant that even though distillation has higher drinkability and cleanliness rates, microplastics were found in the water. In order to understand the data better, I found the mean, standard error, and slope of each filter's data. Conducting this math gives an exact rate at which the water changes from dirty to clean. The filter that best filters microplastics out of rainwater is the manufactured filter. In the end, I learned the manufactured filter was faster, had fewer microplastics, and was cleaner statistically. The quality of these filters are nicer and cleans the water exceptionally. Unfortunately, I ran into a couple of issues like finding personal time to conduct the experiment. I did end up finding a solution to by-step this, by using different equipment. This project taught me many things about plastic in the world, and has spurred a spark in me to continue learning about this field of science.

Coral Bleaching

To understand the effect of certain characteristics on coral bleaching, the researcher plans on observing a variety of traits through data gathered by the National Oceanic and Atmospheric Administration (NOAA). This data will be compiled into a spreadsheet where each factor of coral bleaching can be compared to observe the highest contributors and become aware of any discrepancies.

The Effect of Tsunamis on Coastal and Marine Life


The purpose of the investigation was to find out what sort of barrier would be most effective against a tsunami. The hypothesis was ‘If a man-made barrier is used in addition to natural barriers, then the overall displacement will be lower when compared to no man-made barriers used’. The results showed that a manmade barrier provided the most protection against land erosion and the second-most  protection of aquatic life. The average total displacement of the land was much less than the average total displacement of aquatic life. The hypothesis was partially supported by the data. Some possible errors with the technique may have influenced the project. The project showed that tsunamis are, in fact, uncontrollable. Some future experiments that would be interesting to do are potential ways to ‘freeze’ the ground underwater to prevent erosion.

Is it possible for the relationship between zooxanthellae and corals to be recovered after 
a coral bleaching event?

Coral reefs support the most species per unit area than any other marine ecosystem, and support 4,000 species of marine animals because they can provide food and shelter for them. When corals are stressed due to environmental stressors, zooxanthellae, the algae attached to the coral, will be expelled from the tissues of the coral, and as a result, the coral becomes “bleached” and turns white. I am Almina Kocabas from Brussels American School, in Sterrebeek, Belgium, and my research focused on investigating whether the effects of coral bleaching could be reversed; my mentor, Doctor Shani Bourn and I have been curious about this topic, so I have decided to research it. The current increase of global temperature as a result of climate change is the most prominent cause of coral bleaching. Since pre-industrial temperatures to the 2020s, the oceanic temperatures have increased by more than 1 degree Celsius, resulting in heat waves that cause mass bleaching events of corals all over the world. Without corals and algae supplying nutrients to the ecosystem, entire marine biomes and species will be annihilated leading to a severe loss of biodiversity and of natural aesthetic treasure. Is it possible for the relationship between zooxanthellae and corals to be recovered after a coral bleaching event if the temperature of oceanic water reaches 23 to 30 degrees Celsius. Then the heat-sensitive zooxanthellae could return to the coral’s tissue and begin cycling biochemicals once more, reestablishing coral reef biomes and food webs.

Investigation of Plasma And How to Make a Smaller Generator of it

The purpose of the research project was to figure out a smaller way of creating plasma to allow nuclear fusion to run in a smaller environment. This project was trying to find this because nuclear fusion usually takes up large amounts of space. The experiment the project used was creating plasma with grapes, and other watery objects of similar size, inside a microwave. My hypothesis was “If microwaving one grape (cut down the center), or two watery objects the size of grapes next to each other, then the object will agitate the air around it producing plasma.” This experiment used grapes and strawberries as something of similar size. Another variable introduced in the experiment was a beaker that covered the subjects while in the microwave. The results of the experiment were the grapes having substantially more plasma being produced. The strawberries had very low performance with only one test producing plasma. The grapes with a beaker over them had incredibly more plasma produced. The conclusion of the project was that it is possible to create plasma within small environments, but specific requirements have to be met with the shape, size and structure of the object.
