Science Fair Project Idea

Engineering Design Process

Drones are small, fast, and maneuverable - this can make them very hard to knock down! Check out this Mark Rober video where he explores both how professional defense companies and some backyard YouTube engineers tackle the problem of knocking drones out of the sky. Can you take this engineering challenge on yourself? What methods can you devise to take down a drone? Which one works the best? Drones can be expensive, and you probably do not want to risk damaging a $1,000 drone for your science… Read more

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? Read more

What's the Fastest Way to Sort a List?

Science Fair Project Idea

Scientific Method

Imagine that you have a list of names of all the people in your class. Someone asks you to put them in alphabetical order. How would you go about doing it? Would you first go through the entire list and look for all the "A" names? Then go through it again and look for all the "B" names, and so on? Do you think going through the list over and over again for each letter would be inefficient? What if you had hundreds, thousands, or even millions of names? How would you ever alphabetize them… Read more

Where There Is Charge, There Can Be Sparks!

Science Fair Project Idea

Scientific Method

Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

Which Wing Design Creates the Greatest Lift?

Science Fair Project Idea

Scientific Method

Have you ever flown in an airplane, or looked up at one flying in the sky, and wondered how such a massive machine can stay in the air? Airplanes can stay in the air because their wings, also referred to as airfoils, generate lift. Engineers use devices called wind tunnels to experiment and test different wing shapes when they design new airplanes. Wind tunnels let engineers make careful measurements of the air flow around the wing, and measure the amount of lift it generates. If you can get… Read more

Why Do Flying Rings Go So Much Further Than Frisbees?

Science Fair Project Idea

Scientific Method

If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out! Read more

Why Winglets?

Science Fair Project Idea

Scientific Method

Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for? Read more

Wire Wilt: How Light-Emitting Diodes Fade As Temperature Increases

Science Fair Project Idea

Scientific Method

What's your favorite thing to do on the hottest day of the year? Dip your toes in an icy river? Hang out by the pool? Retreat to a cool basement? Lie motionless in the shade? You're probably not too eager to move around and put out a lot of energy, like mowing the lawn in the mid-afternoon sun. Well, you're not the only one. In this electronics science fair project, you'll find out that some semiconductor devices, like light-emitting diodes (or LEDs), act the same way. As their internal… Read more

Wood Adhesive Durability

Science Fair Project Idea

Scientific Method

The different species of wood used in construction offer a variety of challenges based on density, porosity, oils in the wood, flexibility, elasticity, etc. The intended use, e.g., structural or cosmetic, presents different challenges as well. The glue must be compatible with the wood, the use, and the climate, so many experiments are possible. For example, you could design an experiment to test the durability of different adhesives using the same wood. Or, you could try different wood… Read more

Write Your Own Calculator Program

Science Fair Project Idea

Engineering Design Process

When you need a calculator, what do you use? A physical calculator? An app on your phone? A web browser? What features does the calculator have? Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more
