How Vines Find Their Spines: Thigmotropism in Morning Glory Tendrils

Science Fair Project Idea

Scientific Method

We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project, you will investigate how plant tendrils respond to touch stimuli. Read more

How to Build an X-ray Machine

Science Fair Project Idea

Scientific Method

When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

The Nose Knows Smell but How About Taste?

Science Fair Project Idea

Scientific Method

Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out. Read more

The Effect of Bridge Design on Weight Bearing Capacity

Science Fair Project Idea

Scientific Method

Build model bridges and then deliberately destroy them? Who'd be crazy enough to try that? Read more

Squishy Robot Simulator

Science Fair Project Idea

Scientific Method

What do an octopus, an elephant's trunk, and an earthworm have in common? They are all squishy, bendable and flexible because they do not have any bones inside. You might not typically think of robots as "squishy," but scientists are increasingly trying to create soft robots that look and move like animals. In this project you will use a "soft robot simulator" to design and race your own squishy robots. Can you come up with the fastest design? Read more

Simple Lie Detector Test

Science Fair Project Idea

Scientific Method

Have you ever watched a great sports player and imitated his or her moves over and over again? Or have you ever felt really bad when someone got hurt or things just weren't going his or her way? If so, you might be surprised to learn that you have been practicing skills closely tied to lying! In this science fair project, you'll discover how your brain gets a workout when it moves from truth-telling to lying, and how you can detect the shift. That's no lie! Read more

Fighting the Flu: How Your Immune System Uses Its Memory

Science Fair Project Idea

Scientific Method

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more

A Battery That Makes Cents

Science Fair Project Idea

Scientific Method

Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. How many coins in the pile will make the most electricity? Read more

When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

Can Every Part of a Plant Regrow?

Science Fair Project Idea

Scientific Method

Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others. Read more
