Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up? The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object. Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling… Read more

Satellite Collision Detection: A Hands-On Coding Experience

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what would happen if two satellites crashed into each other in space? While space may seem empty, Earth’s orbit is actually crowded with satellites and debris. In this project, you’ll step into the role of a space engineer, using real satellite data to model orbits, track their movement, and predict potential collisions. You’ll explore how gravity and speed affect a satellite’s movement and learn how scientists use simple math and code to prevent… Read more

Save Those Spoiling Strawberries!

Science Fair Project Idea

Scientific Method

Fresh strawberries and summer just go together. Walking through the local farmers' market on a warm day, the bright, red strawberries call out to you, beckoning you to buy them and take them home. The next day, as you get ready to savor the delicious berries, you notice that yesterday's juicy, red strawberries are now covered in...eewwww, mold! In this cooking and food science fair project, you will investigate thermotherapy and whether this technique can preserve strawberries and prevent mold… Read more

See Air Currents with Shadowgraphs and Schlieren Images

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more

Light is fascinating! It can look like a wave or a particle; it can be red, blue or any color of the rainbow; you can even mix all the colors together to get white! It travels in straight lines and still appears to bend around objects. It can travel through air, but it does not need the air. Unlike sound, light can travel from distant stars through a vacuum and reach us years later, or it can be sent through fiber optic cables and go around the world in less than a second! Does that sound… Read more

Set Your Table for a Sweet and Sticky Earthquake Shake

Science Fair Project Idea

Scientific Method

Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking. Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more

‘See a penny pick it up, all day long you’ll have good luck!’ – maybe you’ve heard this phrase before, and maybe you’ve even stopped to pick up a lucky penny off the sidewalk. But sometimes those pennies you see on the ground look anything but lucky. They look brown or black, and sometimes they’re so dirty looking that you can’t even tell whether they’re pennies! In this activity we’re going to explore why pennies don’t… Read more

Simple Harmonic Motion in a Spring-Mass System

Science Fair Project Idea

Scientific Method

Many things in nature are periodic: the seasons of the year, the phases of the moon, the vibration of a violin string, and the beating of the human heart. In each of these cases, the events occur in repeated cycles, or periods. In this project, you will investigate the periodic motion of a spring, using a mini Slinky®. You can also measure the motion of your spring using a smartphone equipped with a sensor app. Basic physics will then allow you to determine the Hooke's Law spring constant.… Read more

Our planet recycles and reuses everything on it that is needed to support life. It is an amazing, giant recycling system called the biogeochemical cycle. You can actually model this on a small scale by using a plastic bottle and mud to build what is called a Winogradsky column. In this activity, you will build your own Winogradsky columns and investigate how including different nutrients can affect which soil microorganisms flourish and which fail. Read more
