The Kids' Science Challenge is chock full of inspiring videos, fun games, and downloadable hands-on science activities. In this sports science fair project, you will investigate whether a skateboarder's initial speed affects the length and height of the ollie. Describe how large, hard wheels perform differently than small, soft wheels. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use.

The goal of this project is to design and do experiments that demonstrate which skateboard wheels are best for speed and maneuverability. It is often used as the basis of other more complicated tricks. Your #1 source for 7th grade science fair projects and experiments. Show the data from the two types of wheels side by side under the three experimental categories. Did you detect any difference in maneuverability between the two different wheels in Experiment 3? How is friction important in the push off and in the rolling speed of a skateboard wheel? Let your assistant know the day, time, and place of your experiment. You can find this page online at: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Sports_p055/sports-science/popping-an-ollie-skateboarding-physics. Isn't that how gravity works? What are the forces that affect the skateboarder as he or she rides? 118 Views. Skateboard Extremes: Which Wheels are Best for Speed & Turns? Science Buddies Staff. But I have no ideas what topic, I dont want answers like newtons law or gravity, I want questions or topic ideas. If you were to repeat theses experiments would you get different results using your board, local terrain, and different sets of wheels? [Chris Neal] is starting his hacking career young. The skateboarder needs to skate near a wall or a landmark so that you can use it to make marks and observations. Using a timer function in the digital camera, record the time that you are in flight during an ollie. Rewind the video and read the height of the ollie from the recording. To find out, start by doing some background research on skateboard wheels and the basic physics that describes their spin and speed. The glide you enjoy after initial push off on your board demonstrates, at least briefly, the constant speed or velocity from inertia, and the slow roll to a stop indicates that frictional forces have finally robbed you of your forward motion. You, or someone you know, must already own a skateboard and safety gear, and know how to skate to perform the ollie trick. To reduce error in your measurements, repeat steps 5–7 two more times. Como hacer GUIA DESLIZANTE para SIERRA DE MESA ️ DESLIZADOR⬅️ Cortes EXACTOS - Duration: 14:30. el Rincon de Vicente Recommended for you Those rotating wheels speeding along smooth cement parks or clicking across bumpy sidewalks follow the same laws of friction and rotational momentum as the classic incline plane and trolley in a physics lab. Or should you use some other combinations of wheels? At the same time, the science and art of skateboard manufacturing was being fine-tuned and developing rapidly. Science Projects With Bicycles, Skateboards, and Skates (Score! Do the experiment and find out. The first action is the skateboarder jumping up and off the board. I want to do my science fair project on skatebording. Clearly label each mark with its height from the ground. Were you surprised at your results? Shouldn't the board fall to the ground, along with the skater? For help creating graphs, try this website: Try one of our science activities for quick, anytime science explorations. Learn from the largest collection of how to step-by-step projects anywhere. When a skateboarder decides to perform an ollie, the first step is to crouch down slightly. If there is no friction, then a heavier and lighter skateboard should travel the same distance when they are released from the same point on the inclined plane. Use the meterstick and make the marks every 1/4 m, starting from the ground. The volunteer who is observing how far the person jumps should note the location of the front of the skateboard when it lands. See how high the experienced skateboarder (you, or someone you know) can go, and how far he or she can jump! Were the results consistent between the two experiments? The skater and the board are level at this point and look stuck together. Record the number of bottles that do get knocked over in each run. A larger wheel rotates over a longer surface distance per revolution than a smaller wheel, so larger wheels produce more speed per push, if all other factors are equal. Record all data in your lab notebook. Large area that is free from pedestrian and automobile traffic. Have the person pop the ollie. Let's learn more about this trick. How does the shape of the skateboard affect ollie length and height? https://www.youtube.com/watch?v=eHJoHLUV0aU. You will obviously need a skateboard- it isn’t suggested that you attempt this project if you have never skateboarded before. Record all data in your lab notebook. Total the number of bottles knocked over in Experiment 3, and calculate an average number of "knock overs.". What is really cool to watch is when they jump over obstacles—the board seems to stick to the skater's feet in midair. By definition, the skateboard is a compound machine, as it's a device that includes more than one simple machine. How do large wheels differ from small wheels in surface frictional forces? What is your enthusiasm for science after doing your project? 03:22 What It Takes To Be A Yo-Yo Master. For any other use, please contact Science Buddies. They knew that large wheels are supposed to be faster than smaller wheels, according to seasoned skateboarders and skateboard manufacturers. Make sure that you can see the numbers on the wall clearly on the video camera. showing Jonathan Perez from Circle-A Skateboards ollie over a city structure. Science Buddies Staff. Skateboard wheels have morphed into synthetic, highly engineered structures made from resilient, lightweight and durable plastics that encase sleek metal ball bearings to provide the smoothest and fastest spin. Then the skateboarder presses down with his or her rear foot, sharply, on the tail of skateboard. Set up the area where you will be doing the ollies for the science fair project. ", Michelle Maranowski, PhD, Science Buddies. Yes, I Did This Project! Science Fair Project Idea Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The goal of this project is to design and do experiments that demonstrate which skateboard wheels are best for speed and maneuverability. The first ollie will be performed at zero speed; in other words, in the spot on which the person is standing. Generally, hard wheels mean greater speed, while softer wheels travel more slowly because they interact more with the tiny bumps in the road as you move along. The goal of this sports science fair project is to investigate the effect of speed on the distance and height of the skateboarding trick "the ollie. Price … So how does it work? These designs have come about to large degree from manufacturing engineers applying a solid understanding of the physics of wheels and rotational motion. It is composed of three parts: (1) the board, (2) the wheels, and (3) the trucks, which connect the wheels to the board. Finally, gravity takes over and pulls the skater and the board back to the ground. There are three forces that come into play as the skateboarder rides forward on his or her skateboard. The beginning of the Ollie consists of two basic actions, occurring at roughly the same time. Our Science Careers pages provides resources for future scientists from elementary through college. Tests will be carried out on 5different types of bearings Instructions preview: 1. Overall, how would you rate the quality of this project? The person performing the ollie must wear a safety helmet, elbow pads, and knee pads. If most people got on a skateboard, they would roll forward slowly for a few feet, then fall down and break their wrists. Please enter a search term in the text box. One person will perform the ollies, one will videotape the ollies, and another person will help to mark the length and height of the jumps.
