Slippery Slopes and Sticking Surfaces: Explore the Forces of Friction

Science Fair Project Idea

Scientific Method

Whoopee! No matter what age, who doesn't like flying down the slides at parks and pools? In this experiment, you might be surprised what you can learn about the fascinating forces of friction while sliding down (or sticking to) those fun, slippery slopes. Caution: only speed demons need apply for this activity. Read more

How Much Weight Can Your Boat Float?

Science Fair Project Idea

Scientific Method

Have you ever wondered how a ship made of steel can float? Or better yet, how can a steel ship carry a heavy load without sinking? In this science project you will make little "boats" out of aluminum foil to investigate how their size and shape affects much weight they can carry and how this relates to the density of water.

What Materials Can Block a Wi-Fi Signal?

Science Fair Project Idea

Scientific Method

Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router. Read more

Build a Jumping Robot

Science Fair Project Idea

Engineering Design Process

Can you build a robot that hops like a frog? In this engineering project, you will learn how to build a simple robot that uses the energy stored in a stretched rubber band to jump. You will use the engineering design process to try to make your robot jump higher and farther. How far can you make it jump? Read more

Are Fingerprint Patterns Inherited?

Science Fair Project Idea

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

How Acidic Waters Make Rocks Disappear

Science Fair Project Idea

Scientific Method

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Deep Knee Bends: Measuring Knee Stress with a Mechanical Model

Science Fair Project Idea

Scientific Method

Are you interested in things like prosthetic limbs and artificial joints that can help people with disease or injury to lead a normal life? Or maybe you're interested in sports medicine or physical therapy? Either way, this project could be a good match for you. Find out how the tension on the knee joint changes as a function of angle by building a simple mechanical model. Read more

Blood Clotting to the Rescue: How to Stop Too Much Blood from Flowing

Science Fair Project Idea

Scientific Method

Have you ever had a cut or a bloody nose that seemed like it would bleed forever? Though it might have seemed like a long time, it probably did stop pretty quickly. This is because different factors in a person's blood normally work together to plug the opening caused by the cut in a process called blood clotting or coagulation. However, some people have a genetic disorder called hemophilia that causes them to bleed excessively. If a person has hemophilia, he or she is usually missing some of… Read more

Build a Robotic Arm

Science Fair Project Idea

Engineering Design Process

Robotic arms have many uses, ranging from assembling things in factories to collecting soil samples on Mars to acting as prosthetics (artificial limbs) for humans. If you have ever wanted to build your own robotic arm, this project will guide you through the basics of designing and building a simple one. You can use this design as a starting point to design your own robotic arm and add your own features. Read more

Focusing Your Flash for 'Freezing' Motion

Science Fair Project Idea

Scientific Method

Here's an interesting flash photography project. With an inexpensive Fresnel lens, you can concentrate the light from your flash. You'll be able to shoot with a smaller aperture and a shorter flash duration. This will give you greater depth of focus and will allow you to 'freeze' motion at higher speeds. The trade-off is that the light will be concentrated toward the center of the frame. This project shows you how you can investigate that trade-off and find out how you can best use your flash… Read more
