Science Fair Project Idea
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… Read more

Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you'll choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more

Have you ever seen a tortoiseshell cat? "What kind of cat is that?" you might ask. A tortoiseshell cat has two different fur colors, black or brown and red or orange. The gene that gives rise to the red or orange fur color is on the X chromosome. And did you know that most tortoiseshell cats are female? That's because female cats have two X chromosomes, while males only have one, which allows the females to express two different color combinations! Try this science fair project to figure out… Read more

Science Fair Project Idea
The Pilobolus fungus has an interesting way of making sure the next generation has a good start on life. At high speed, the fungus shoots a sac that contains spores toward a light source. Why toward a light source? Because that is where it is most likely to find an open area with grass. Once the spore is placed on grass, it is eaten by a cow or a horse, which is a critical step in its life cycle. The spore passes through the animal's digestive track and ends up in a pile of manure. For a fungal… Read more

You are coming into the house after a game of flashlight tag with your friends, but the front porch light is not on for you to see the doorknob! What is going on? Maybe your parents know that turning a light on means moths will gather there, and they do not want you letting moths inside when you open the door. You have probably noticed how moths are attracted to lights at night. They will even fly dangerously close to flames in their journey toward light. In this project, you will learn a… Read more

How do you figure out how to get places? Do you ask for directions, look at a map, or consult a compass? There are many ways for people to figure out how to travel from one place to another, but how do other animals do it? In this science fair project, you'll use real data, collected by biologists, to figure out how migratory birds manage to navigate more than 2,000 miles from their breeding grounds to their wintering grounds.

Do you like drawing or painting? What if you could build a robot friend that creates its own art? In this project you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you have wanted to try building your own robot, this is a great place to start! Read more

In the mid-20th century, people thought of robots as futuristic tools. But in the 21st century, robots are not a figment of our imaginations, but are a part of our reality. Robots even perform tasks that humans can't do. In this engineering science fair project, you will use LEGO Mindstorms to build a robot that is fast, lightweight, and stable. Who knows? You might end up building a robot that does housework or even your homework! Read more
