Aerodynamics and Bridge Design

Science Fair Project Idea

Scientific Method

Research the famous collapse of the Tacoma Narrows suspension bridge. What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis. Read more

The Chemistry of Clean: Make Your Own Soap to Study Soap Synthesis

Science Fair Project Idea

Scientific Method

Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more

Encryption

Science Fair Project Idea

Scientific Method

Want to send coded messages to your friends? Can you write a simple letter-substitution encryption program in Python or JavaScript? How easy is it to break the simple code? Can you write a second program that "cracks" the letter-substitution code? Investigate other encryption schemes. What types of encryption are least vulnerable to attack? Read more

Disappearing Act: How Fast Do Different Biodegradable & Compostable Materials Decompose?

Science Fair Project Idea

Scientific Method

Have you ever seen a product labeled "biodegradable" or "compostable" and wondered just how well it decomposes? A lot of different products claim to be biodegradable or compostable, such as food containers, bags, packaging materials, and spoons and forks. Not only do they clearly come in different shapes and sizes, but they are made of different materials as well. Do they decompose differently, and, if so, which decomposes the fastest? In this science project, you will make your own indoor… Read more

Finding the Center of the Milky Way Galaxy Using Globular Star Clusters

Science Fair Project Idea

Scientific Method

The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole 3-4 million times the Sun's mass, is hidden by dust clouds in space. In this astronomy science fair project, you will use astronomical data to locate the center of this galaxy. Read more

Can AI Classify Stars?

Science Fair Project Idea

Engineering Design Process

Understanding the different types of celestial objects in our galaxy is important for astronomers. It helps them study how these objects form and evolve, map the night sky, understand the structure of the Milky Way and other galaxies, and identify celestial bodies that might host habitable environments. In this project, you will create a boosted tree model to classify celestial objects based on their spectral characteristics. Read more

How Much DNA Can You Pack into a Cell?

Science Fair Project Idea

Scientific Method

Have you ever tried to pack a suitcase? If so, you know that no matter how hard you try, there is a limit to the amount you can cram in, which means if you have more stuff, you need a bigger suitcase! Do you think the same principle applies to DNA in a cell? Does an animal with a bigger genome need a larger cell nucleus to store its DNA? Try this science project and find out! Read more

Where There Is Charge, There Can Be Sparks!

Science Fair Project Idea

Scientific Method

Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more

Simple Circuit Logic with Switches: An Electric Puzzle

Science Fair Project Idea

Scientific Method

Here's a puzzle you may have heard before which you can build as a simple electric circuit. First, the puzzle: a farmer is traveling to market with his cat, a chicken and some corn. He has to cross a river, and the only way to cross is in a small boat which can hold the farmer and just one of the three items he has with him. The problem is, he has to be very careful about what he chooses to leave behind at any time. If the cat and chicken are left alone, the cat will eat the chicken. If… Read more
