Riprap: It's Not Hip Hop But Erosion Stop

Science Fair Project Idea

Scientific Method

Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water. Read more

Weather and Climate in Your Neighborhood

Science Fair Project Idea

Scientific Method

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more

The Wagon Wheel Effect

Science Fair Project Idea

Scientific Method

Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Crossed Up: Does Crossed Hand/Eye Dominance Affect Basketball Shooting Percentage?

Science Fair Project Idea

Scientific Method

Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed).

A Study of Gender Responses to Frustration

Science Fair Project Idea

Scientific Method

Have you ever felt really frustrated? Maybe you were playing a video game and could not easily figure out a particularly challenging puzzle. Or maybe there was something you really wanted but you could not have it for some reason. However it has happened, what do you do when you get frustrated? What about other people — what kind of behaviors have you seen others display when they get frustrated? Do they cry, jump up and down screaming, just give up, or become aggressive? In this human… Read more

The Buoyancy of Balloons

Science Fair Project Idea

Scientific Method

Balloons are a festive addition to many celebrations. You've probably noticed, though, that over a short period of time, helium-filled latex balloons start to lose their buoyancy. So when you're planning your next party, how soon can you buy the balloons in advance before they start deflating? In this science fair project, you will use a simple scale to measure the lift supplied by a set of balloons, and determine the rate of lift decay. Read more

It's Written All Over Your Face: The Science of Facial Expressions

Science Fair Project Idea

Scientific Method

Okay, now you've done it. You goofed off, didn't study for your math test, and didn't do well. Mom and Dad are not going to be happy. In fact, they might even be angry. They don't say anything when they see your test, but you can tell from their faces that they are angry. But how can you tell? How can you tell if someone is angry, or happy, or sad? The answer is that you have learned how to tell someone's emotional state from his or her facial expressions. Are facial expressions of happiness or… Read more

Ring of Fire 1: What Volcanoes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data. Read more

Pencil Resistors

Science Fair Project Idea

Scientific Method

What do you do with your old wooden pencils when they get too short to hold? Don't throw them away; you can use them to make circuits! This project will show you how to use pencils to make resistors, an important part of many electrical circuits, and test how they affect the brightness of a lightbulb in a simple circuit. Read more

Recycling Greywater: Can Plants Tolerate It?

Science Fair Project Idea

Scientific Method

One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more
