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…

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…

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights.

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.…

What happens when a satellite collision in space leads to a chain reaction of more collisions? This project models The Kessler Syndrome: A scenario in which collisions between satellites in low Earth orbit create increasing amounts of debris, eventually making the region too dangerous for satellites or spacecraft to operate safely. By adjusting key variables like collision rates and debris generation, you can visualize how quickly space around Earth could become overcrowded, and explore…

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…

Forces, which we might instinctively describe as pushes and pulls, are acting on us at all times, but we cannot always see them. This hands-on lesson offers a fun opportunity to explore "invisible" forces like gravity and air resistance. Students will build parachutes and investigate how they allow skydivers to safely land.
