What's The Best Way to Land a Model Rocket?

Science Fair Project Idea

Scientific Method

What's the best way to land a model rocket? What makes the rocket hit the ground safely at a low speed? What prevents the rocket from drifting too far if it's windy? In this project, you will make your own rockets from paper towel tubes and drop them to test different recovery methods like parachutes and streamers. What method do you think will work the best?

Make a Heart Rate Monitor

Science Fair Project Idea

Engineering Design Process

People have a variety of reasons to use heart rate monitors. For example, patients in a hospital might have stationary, bedside equipment monitor their heart rate and alert medical staff in case of an emergency. Somebody going for a run might wear a portable heart rate monitor to keep track of their workout intensity. Heart rate monitors are not all the same—their appearance and function will vary depending on the intended use. In this project you will design, build, and program your own… Read more

Racing Bristlebots: On Your Mark. Get Set. Go!

Science Fair Project Idea

Scientific Method

Have you ever wanted to build your very own robot from scratch? Bristlebots are a cheap, easy, and fun-to-build robot made from the head of a toothbrush, a battery, and a small motor. Once completed, they buzz along the top of a table like bugs. How can you make a bristlebot go faster? In this project, you will build bristlebots from two different types of toothbrushes, and race them against each other to find out. Read more

Bouncing Basketballs: How Much Energy Does Dribbling Take?

Science Fair Project Idea

Scientific Method

Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a… Read more

Build a Remotely Operated Vehicle (ROV) for Underwater Exploration

Science Fair Project Idea

Engineering Design Process

Have you ever wanted to explore cold or murky water? What about places where it could be dangerous or difficult for humans to swim? Remotely operated vehicles (ROVs) allow humans to take pictures, videos, and scientific samples of underwater life and habitats while safely operating the vehicle from a boat or from shore. In this project you will design and build your own small ROV that you can test in a bathtub, pool, or nearby body of water. Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Have you ever wondered how predators, like wolves, lions, and hawks, are able to find their prey? And what can an animal do to stay off of a hunter's menu? To survive, some animals have developed specific camouflage tactics to fool their predators. One strategy some animals use is to look very similar to other animals that are poisonous or that the predator doesn't like to eat. This camouflage tactic is called mimicry. In this science activity, you will be the hungry predator and you will hunt… Read more

How Does Color Affect Heating by Absorption of Light?

Science Fair Project Idea

Scientific Method

Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more
