Science Fair Project Idea

Engineering Design Process

Companies like SpaceX and Blue Origin are dramatically lowering the cost of space flight by designing reusable rocket boosters that land back on Earth. Getting a rocket to land vertically without any damage - and without using a parachute to slow it down - is quite a tricky physics problem! In this project you will modify your own model rocket so it can land vertically. Read more

Measuring Sugar Content of a Liquid with a Laser Pointer

Science Fair Project Idea

Scientific Method

Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. Read more

If you've ever been shot with a rubber band then you know it has energy in it—enough energy to smack you in the arm and cause a sting! But have you ever wondered what the relationship is between a stretched rubber band at rest and the energy it holds? The energy the rubber band has stored is related to the distance the rubber band will fly after being released. So can you guess one way to test how much energy a stretched rubber band contains?

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

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

Do you like cooking? If you have helped in the kitchen at home, you have probably heated up lots of liquids, like water, milk, and soup. Did you notice that once the solution boils, a lot of steam develops; and have you ever wondered what the steam is made of? What happens to all the substances, such as sugar or salt, that are dissolved in the solution you are boiling? Do they boil off, too, or do they stay behind in the solution? In this activity, you will build a distillation device that… 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

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

Is Thanksgiving one of your favorite holidays of the year? All your friends and family are getting together to celebrate. The table is full of delicious food—a big feast—and there might even be some fancy China and glassware on the table to make the celebration even more special. Who can resist the temptation to make the wine glasses sing? You have probably done this many times before, but have you ever wondered, why the wine glass makes this sound? Do this activity, and you will… Read more
