Biological Sciences A
Includes animal sciences, plant sciences, and microbiology
“Egg”cellent Hatching Hinges on Humidity
In my experiment, I tested which humidity level resulted in the most successful hatch rate for fertilized chicken eggs in an incubator. Using three incubators, set to three different levels, I was able to achieve a 100% success rate with the lowest humidity level in both of my trials.
Are Mosquitoes Afraid of Mosquito Fish?
In a field study, I evaluated if mosquitoes are repelled from cups containing Gambusia fish. I found that, indeed, mosquitoes avoided laying eggs in cups containing the fish but were not repelled from cups containing fish water, suggesting that the repellent effect is visual rather than chemical
Biological Sciences B
Includes behavioral and social sciences, computational biology and bioinformatics, cellular and molecular biology, and biomedical and health sciences
Germs and Hand Hygiene
My project is about Germs and Hand Hygiene. The best hand cleansing technique is using soap and water.
pH Effect on Microorganisms
This project shows off amoeba. How will pH affect their lifespans?
Do You Have the Heart to Taste?
In this project, I studied the effects of beta-blockers (a type of cardiac medication) on the ability to taste sugar and salt in 50 seniors aged 60 to 80. I concluded that the chemical components in beta-blockers significantly diminish the ability to taste sugar and salt flavors, and cardiologists need to work with dieticians to find spice and flavor substitutes that will not negatively impact their patients' heart conditions.
The Effect of Age on Audio Assessment
For my project I chose to test whether background noise or an individuals age could alter their ability recite a sentence. I read a sentence out loud to my participants in silence and asked them to recite it, I then did the same with background noise present.
Includes chemistry and biochemistry
Split Them Faster
In this project, called 'Split Them Faster', I tested the effect of different water temperatures on the amount of hydrogen released from water. My experiments showed that the speed of electrolysis increased with higher water temperatures.
Plants in Space
Plants in Space: Determining the Nutritional Value of Plants Grown for Space Travel was designed to test the hypothesis that if vegetables, specifically kale plants, are grown using methods currently proposed by NASA for the International Space Station, Mars Missions, and Moon Missions, they will contain similar nutrients to plants grown in soil on earth. Plants were grown in pillow pants, hydroponically, and conventionally, and then tested for levels of protein and Vitamin C.
Student(s): Shivali and Srivya
Electrolytes are vital for everyday nerve and muscle functions. We conducted a project to see which commonly consumed beverages had the most electrolytes.
Clay, Silver, Copper Which One is the Topper?
In my project I explored how water changes and is affected when stored in containers made of Clay, Silver, and Copper. I found out that for long term storage of water that silver or copper containers are the best.
Earth and Envirnomental Sciences
Includes earth and environmental sciences, environmental engineering, and chemical and physical energy
Can you Make a Carbon Sink with What’s Under Your Sink?
CO2 is a massive contributor to the greenhouse effect and global warming. I investigated whether it is possible to sequester carbon dioxide with sodium hydroxide using a device I built at home.
How do Different Soils Affect the pH of Water?
Student(s): Ruby and Terra
Our project was an experiment dealing with soils and pH. We took 3 different types of soil samples from the local area, tested their pH and compared them.
How are Water Ecosystems Affected by Pollution?
Student(s): Vedha and Priyal
How are water ecosystems affected by pollution? Our project’s focus is to show how household products contaminating water bodies affects Lemna minor duckweed.
A Plant’s Defense
The purpose of this project was to see if a variety of unused natural resources can make an alkaline fertilizer. This way, I would be able to neutralize the effects of acid rain on our produce while being efficient with our resources.
Like tiny droplets create ripples in a mighty ocean, New Normal is about taking small actions together to help reverse the effects of the climate crisis. With less than 15 years left to solve this issue, everyone has to do their part to ensure that our future is secured.
Includes engineering mechanics and material science
Swamp Cooler With Vetiver
Student(s): Sesha and Siddharth
Our project is an innovation which uses a natural root to cool the air. This means it can serve as an alternative to Air Conditioning Systems which release very harmful greenhouse gases, further increasing the damage Global Warming has already done.
LED Traffic Glove
Student(s): Tanav and Pranav
This LED Traffic Glove engineering project was designed to direct people/traffic during any major event. This is a fully functional LED Traffic Glove that is bright and powerful to gain attention while being light-weight and safe to use.
Tin Can Antenna
My project was building and testing a tin can antenna to improve our wifi. I found that a tin can antenna can be stronger than a stock router as longs you remain in the antenna's path.
Physics and Mathematics
Includes physics, mathematics, and astronomy
Breaking the Surface Tension
Mosquitoes spread many different diseases such as Malaria and Yellow Fever, they also depend on surface tension to reproduce. If we can break the surface tension then we can kill the mosquitoes, preventing spread of dangerous diseases.
The Sun’s Rays
My project is about which of the two main types of solar cells (polycrystalline and monocrystalline) works better at certain angles. The scientific question I answered was- HOW DOES THE ATTRIBUTES OF THE PHOTOVOLTAIC SYSTEM AFFECT THE EFFICIENCY OF A SOLAR CELL?
Understanding the Impact of G-Force
My research project was to see if I drop an object from a height and see if I could use a formula that can calculate the time it takes for the object to hit the ground. I calculated this by using the Gravitational Force on Earth.
The purpose of this project was to determine how the length of a pendulum affects the time it swings for and the period oscillation. I used pendulum lengths of 6", 8", and 10" and determined that the longer the pendulum, the longer the period time in seconds using Huygen's pendulum equation (T=2pi(L/g)^1/2).
There’s More Than Meets the Eye
My experiment (Electric Lights: There’s more than meets the eye) measured the true efficiency of four different types of lightbulbs by determining the amount of energy that was converted to light and heat. My experimental results showed the following relative efficiencies for the tested lightbulbs: LED (55%), Compact Florescent (48%), Halogen (15%) and Incandescent (14%).
Cast Me with Your Best Line
This experiment is to test and see does the weight of the fishing line affect the distance of the cast to see if this helps individuals with limited mobility.
Includes embedded systems, robotics and intelligent machines, systems software
Water me, Please!
I have made an Arduino-based, Automatic Irrigation System. This is used to provide the plants with right amounts of water so it is beneficial for the plant's growth.
