High School Science Projects (327 results)

Science Buddies' high school science projects are the perfect way for high school students to have fun exploring science, technology, engineering, and math (STEM). Our high school projects are written and tested by scientists and are specifically created for use by students in the high school grades. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, high schoolers can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Science Fair Project Idea
Are you an artist, or do you enjoy the process of making art? What kind of art do you create? Do only humans make art? Not all the time. Robots can create art, too. Robots can be programmed and "taught" to do all kinds of things, such as delivering medications to hospital patients or putting together a car on an assembly line. The Vangobot™, shown in the video below, paints pictures with brushes and paint, and in a distinct, unique style—just like a human artist. Watch… Read more

The sustainability of our planet's resources ultimately depends upon our actions as citizens. How much we drive, what we eat, whether we have pets, and whether we recycle are all individual actions that affect the sustainability of the Earth's resources. Learn how ecological footprinting works and figure out how big your footprint is. How big is your family's footprint? Your school? A local business? Can you propose ways to increase or decrease the size of your ecological footprint? Develop… Read more

Although fractal images can be intriguingly complex, fractals are more than just pretty pictures. In this project, you'll explore the mathematical properties of the famous Mandelbrot (illustration on the Background tab) and Julia sets. You'll learn about how these images are generated, and about the relationship between the Mandelbrot set and the Julia sets. Read more

The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more

Unlocking the three-dimensional structure of a protein is crucial to help scientists understand how it functions in our bodies and how it can cause devastating diseases if it becomes disrupted or interacts in the wrong way. However, figuring out the structure of a protein in three-dimensional space can be very challenging. Proteins are the functional units of our cells, and every protein is made up of a long chain of amino acids. Amino acids come in different shapes and sizes, and they have… Read more

You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use Google's Science Journal app to demonstrate how the data can be picked up by a nearby smartphone. Read more

Safety Notes about Neodymium Magnets: Handle magnets carefully. Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched. Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer… Read more

When an earthquake occurs, seismic shock waves travel out through the earth from the source of the event. The shock waves travel through the earth or along the Earth's surface, and can be recorded at remote monitoring stations. Some of the waves that travel through the earth are blocked or refracted by the Earth's liquid core, which means that monitoring stations located certain distances from the earthquake do not detect these waves. This creates a "seismic shadow" that you can use to… Read more

Time Required Long (2-4 weeks)
Prerequisites This project uses the Global Earthquake Explorer program to download and analyze data from a global seismic network. In order to do this project you will need to be comfortable installing and working with a new program on your computer. This project requires a computer with high speed Internet access. You will also need to understand some basic trigonometry. You should be comfortable with determining the lengths of the sides of right triangles when given an angle and the length of one side. Experience looking at seismograms is useful but not required.
