Rokenbok is a single, continuous system of reusable materials carefully organized into Mobile STEM Labs. Students start with building blocks and, at each stage in their STEM journey, add new engineering elements and design challenges all the way through programmable robotics. Students start with fundamentals like how to make things strong and how to make things move. As students mature, they build on that foundation and explore: mechanical and structural engineering; Computer Aided Design and 3D Printing; the mechanical, programmable, and sensor driven aspects of robotics; and integrated. Its much more easier when you watch a youtube tutorial video or read instructions. This is the easiest way to create a 3D roller coaster.]]> 2017-05-18 19:26:38 UTC https://padlet.com/quintanilla_eri/5qgij57sph8p/wish/172674507 Steps to creating a roller coaster quintanilla_eri https://padlet.com/quintanilla_eri/5qgij57sph8p/wish/172856242
  • Spherical objects such as marbles and ball bearings tend to make the best "cars" for your roller coaster. The size of the marbles/balls needed depends on the type of material you use for your tracks. For instance, while vinyl tubing works well to make tracks that bend and curve, only small objects like B-Bs and ball bearings can actually fit in most vinyl tubing. However, vinyl tubing is probably the easiest material to make tracks with, so we recommend using it for your first attempt at making a roller coaster. Most hardware stores carry vinyl tubing in a variety of sizes, so test your cars to make sure they can move through it before you purchase it.
  • If you use poster board or cereal boxes, cut out long strips to make your track. You may have to build walls or sides to keep your car from falling off.
  • Whatever material you use, build your track so that the cars can run smoothly on it - no cracks or seams that will trip up the cars.
  • Use the adhesives to connect track pieces together as well as connect the track to your support system.
  • Remember the laws and forces of motion when building your roller coaster track. Your first hill must be the tallest to build up enough potential energy to get your car through the track. Adjust hills and loops so that the car will have enough velocity to make it through the course without having so much speed that it flies off.
  • You may want to try several different cars with different sizes and weights to see which car moves through your track the best.
