Warning! In order to complete this webquest, read EVERYTHING. If, after reading everything, you are still unclear about a step, see me. Click hereTO DOWNLOAD THE PACKET.What's the best part of an amusement park? While some might say cotton candy, churros, or water rides, I believe the best part of amusement parks are the humongous roller coasters. The bigger the better!! Why Roller Coasters? Because they're awesome thrill-seeking, scream-provoking, vomit-inducing machines. Even though these rides feel dangerous, they're actually very safe inventions designed to feel as if you're breaking all rules of science. Are they? Of course not, physics plays a huge role in the design, motion, & fun of roller coasters.

Part 1: Physics Research:
Before designing a roller coaster, you need to know the physics fundamentals.

Step A : Terms to know
Remember Newton's 2nd Law? ..Remember acceleration??
............................yeah.... that's what I thought.. :)
Define the following words. PUT in your own words, but you can find the definitions here:
Acceleration: click here
Centripetal Force : click here
G (force) : click here
Newton’s 2nd Law : click here
Kinetic Energy (KE): click here
Potential Energy (PE) : click here

Step: G: Roller Coaster Elements
Batwing ..... Butterfly Inversion ..... Camelback.... Cobra Roll....Corkscrew .... Diving Loop ....
Hammerhead Turn .... Heartline Roll .... Horseshoe .... Immelmann Loop .... Norwegian Loop ....
Pretzel Loop .... Raven Turn .... Sea Serpent Roll .... Top Hat ..... Vertical Loop
use the sites listed below, or just "Google" the terms:

Step: H: Did you know?? Roller coasters use an engine & cable only at the first hill.
After that, no more external energy is added to it! That's amazing!

Design & Planning
There are many different styles of roller coasters. Build yours on line, and answer the questions for part J

Step: J: Build your roller coaster on line: click here / click here
Planning Your classroom coaster: Think about what part of the room you want to build your marble roller coaster in. What kind of special features do you want? Hills? Loops? Corkscrews? Your group will be provided with 6 foam insulation pipes and a roll of masking tape. Jot down at least 5 of your ideas.

Testing: Now go build that Roller Coaster!
