Science Fair Project Idea
Engineering Design Process
Have you ever wondered what would happen if two satellites crashed into each other in space? While space may seem empty, Earth’s orbit is actually crowded with satellites and debris. In this project, you’ll step into the role of a space engineer, using real satellite data to model orbits, track their movement, and predict potential collisions. You’ll explore how gravity and speed affect a satellite’s movement and learn how scientists use simple math and code to prevent… Read more

Scientific Method
In a survey conducted from 2007 to 2010, the U.S. Centers for Disease Control and Prevention reported that about 49% of people in the United States had taken at least one prescription drug during the past month, and about 22% of people had taken three or more prescription drugs. People are prescribed drugs all the time, but prescriptions can be dangerous because people can have different responses to drugs. These responses largely have to do with genetic mutations. Why are some genetic… Read more

Scientific Method
Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?… Read more

Do you know anyone who is colorblind, or are you colorblind yourself? What if you could carry a device in your pocket that could identify colors for you? Many people already carry around the device they need to do this - a smartphone! Since phones have built-in cameras, you can make an app that uses the camera to identify colors. In this project you will use a program called MIT App Inventor that makes it easy for anyone, even with no programming experience, to design your own mobile app.  Read more

Scientific Method
Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more

Scientific Method
This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more

Scientific Method
Have you ever wondered why silver jewelry that starts out nice and shiny turns brownish-black and dull over time? The brownish-black stuff is called silver tarnish, and it is the result of a chemical reaction on the silver's surface. Luckily, there are many ways to clean tarnished silver and make it shiny again! In this science project, you will explore how to clean tarnished silver using electrochemistry. The electrochemical silver cleaning reaction requires aluminum and a salt solution. Your… Read more

Scientific Method
You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. Read more

Engineering Design Process
Do you think you can win tic-tac-toe against an AI player? In this project, you will explore how the Minimax algorithm makes decisions in two-player games such as tic-tac-toe. This project requires little to no coding skill; instead, you will need an open mind and curiosity. Why not give it a try yourself? Read more
Science Fair Project Idea
Scientific Method
Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.
