Biological Sciences A

Includes animal sciences, plant sciences, and microbiology

“Egg”cellent Hatching Hinges on Humidity

Student(s): Anna-Leah

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?

Student(s): Noga

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

Student(s): Ahish

My project is about Germs and Hand Hygiene. The best hand cleansing technique is using soap and water.

pH Effect on Microorganisms

Student(s): Aiden

This project shows off amoeba. How will pH affect their lifespans?

Do You Have the Heart to Taste?

Student(s): Avery

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

Student(s): Josie

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

Student(s): Ana

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

Student(s): Isabella

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?

Student(s): Dyuthi

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?

Student(s): Sarrah

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

Student(s): Soyu

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.

New Normal

Student(s): Shruti

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

Student(s): Thomas

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

Student(s): Anderson

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

Student(s): Ansh

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

Student(s): Arpan

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.

Swinging Time

Student(s): Benjamin

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

Student(s): Lucy

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

Student(s): Ralee

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!

Student(s): Tanush

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.
