Others Like “Roller Coaster Marbles: How Much Height to Loop the Loop?”

Project Idea
thumbnail If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.

Project Idea
thumbnail Do you love roller coasters and other kinds of exciting rides? Are you a thrill-seeker? Well, this is the science fair project for you! What makes a ride so thrilling that people want to ride it over and over again even though it scares them? Is it the speed, the twists and turns, the vertical drops? In this science fair project, you will build and use an accelerometer to figure out what makes a roller-coaster ride worth standing in line for. Oh, and if Mom and Dad ask what an amusement park… Read more

Safety Make sure that you and your volunteers are healthy enough to ride roller-coaster rides. Always take a break and rest if you start to feel ill. Adult supervision is recommended.
Project Idea
This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. Sure, it's been done before, but if you do it yourself, you can get a firm understanding of these important concepts. Read more

Project Idea
thumbnail Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a… Read more

Project Idea
thumbnail Have you ever been so cold sitting in your house in the winter that you feel icicles could grow off your nose and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner—but that costs money. Still, being cozy or cool doesn't have to cost a lot of money if you use a geothermal heat pump. In this project you will build a model… Read more

Project Idea
thumbnail If you have 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 just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Read more

Project Idea
thumbnail Amaze your friends and family by moving water with just a few turns of your wrist! Nope, it's not a magic trick. It's simply an Archimedes screw. In this science project, you will build a very simple pump, called an Archimedes screw, to transfer water from a low-lying location to a higher location. Read more

Safety Minor injury possible. Be careful when cutting the tubing.
Project Idea
thumbnail You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. Read more
