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

Fruit Ripening

Science Fair Project Idea

Scientific Method

Fruit is a strategy some plants use to attract animals to disperse seeds. The animals eat the fruit and disperse the seeds through the digestive system. To attract animals, fruit needs to ripen and develop an odor that acts as an attractant. How much more successful are ripe fruits at attracting animals? Try setting out an over and under ripe piece of fruit, and compare how many many insects are attracted to each fruit. How does ripening occur? You can do an experiment using a very ripe… Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. Read more

Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance

Science Fair Project Idea

Scientific Method

Picture this situation: An elderly woman is rushed to the hospital complaining of severe abdominal pain, tinnitus, and lethargy. Suspecting a drug interaction, the emergency room doctor starts questioning her. The doctor learns that the woman takes no medicines except aspirin for her arthritis. Since she cannot swallow pills well she takes a powdered form of aspirin which she buys in bulk and keeps in a plastic container in her kitchen next to her baking goods. She had just finished a day of… Read more

Lung Capacity and Age

Science Fair Project Idea

Scientific Method

Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more

The Brains Behind 'Where's Waldo?'

Science Fair Project Idea

Scientific Method

What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… Read more

The Cold Wash Challenge: Testing How Well Enzymes Work in Laundry Detergents

Science Fair Project Idea

Scientific Method

What do you think are some of the most common stains on clothes? If you thought of grass, grease, ketchup, blood, or toothpaste stains, you are correct. Everyday activities like eating, playing outside, or doing sports can result in a lot of dirty laundry. Luckily, we have laundry detergents that can get our clothes clean again! Some of these detergents contain enzymes that are intended to boost cleaning power. In this science project, you will investigate how effective biological and… Read more

How Much Current Does It Take To Blow Up An LED?

Science Fair Project Idea

Scientific Method

Have you ever accidentally burned out an LED while building a circuit? What about doing it on purpose—for science, of course! In this science project, you will intentionally send too much current through LEDs to see if they will burn out or even explode! How much current does it take to destroy an LED? How does this compare to the LED's rated current value? Try this project and find out! Check out this page for more LED science projects. Read more

Asteroid! Identify Space Hazards with Computer Vision

Science Fair Project Idea

Engineering Design Process

Space is a dangerous place for astronauts and spacecraft. Earth's orbit is full of potential hazards like meteoroids, space debris, and other satellites that you do not want to crash into! How do scientists detect these objects in space? If you do detect an object, how can you tell what it is? In this project you will make your own computer program that can recognize and react to three different models of objects that can be found in space. No previous programming experience is required!

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
