I. Before you get started with your roller coaster:
        a.    Communication is very important when working together with group members (in a partnership). You are to keep a journal of all communication and decisions that goes on between you and your group members (in a partnership). 

1. You will be placed in groups of four classmates (partnership). 

2. As a group, you will view a video clip on wiki spaces which is a website in which group members will be using to communicate with each other all in one area without having to send emails all over the place. Wiki in Plain English:This website will allow you to be more organized, responsible, move quickly, plan ahead and make your project easier to work as planned. 

3. Each group member will sign up for an account on Wiki Spaces
II. Researching on Roller Coasters:
       a. Most individuals have been to an amusement park where they went on a ride or saw a roller coaster operate..

Perhaps, you never took the time to stop and analyze everything that goes on when operating a roller coaster. Therefore, before you design and build your roller coaster model, you will do internet research on how roller coasters work, watch video clips, analyze the mathematics and physics concept behind it and test your selves on your overall understanding.

So, how does a roller coaster work?

How a Roller Coaster Works
Physics Glossary

1. In order to get motivated,you will get a chance to play around and know how high, low, round/oval  loops and hills should be build on a roller coaster. In this website, you can get a feel on the Basics of a Roller Coaster
2. These websites give you an idea of different types of loops and hills that can be thought of building.  IDEA   IDEA B
3. The starting point of your roller coaster is very important because that is where the most force is needed in order to make it ex: around the loop, over the hill, down a hill, over a another loop and to the end. This website will help you estimate and get a better look of how high or slanted your starting point should be.

4. When building a roller coaster, it is important to understand the differences between Kinetic and Potential Energy,you will visit Operating Roller Coasters, which gives you input on how they work.
5. It is important to understand the physics of how roller coasters work. You will go a website and click on the second button on the right to take a PHYSICS QUIZ to reassure you are ready to take on the challenge of measuring and building your roller coaster model.
6. It is important you know how to scale your design. This website helps out in giving you insight on how to start designing a roller coaster 

However, you might notice they use units that might be too big for your model. You can scale them into inches or centimeters depending on how big you will build your roller coaster model.

III. Designing your Roller Coaster Model

        a. After researching through the websites that were provided, you should now be prepared and comfortable for taking the next step. You will be sketching your design and use appropriate unit scale (using formulas to get measurements for roller coaster calculations) on a graph or plan white paper.

Note: Keep in mind that your design must consist of at least one loop and two hills.
          Since we are testing with  mass of.01 kg (mouse ball) for your roller coaster model
          you will NOT use "actual" roller coaster cart measurements for its mass. 
          You will use .01 kg as the mass.     
1. Getting started:
You will sketch out on scratch paper various times in order to get an picture idea on how your roller coaster will look.

2. Design and Theory: (It consist of six steps)       
Using your picture idea you will then start to sketch your design professionally on graph or plane white paper.  However, you are to complete your roller coaster calculations by using GPE, KE and CF.

Take a last look at Newton's Laws of Gravity and Roller Coaster Article Topics

You will use this image to guide you through your calculations (Roller Coaster Calculations Guide) you will need to open and save a word document to type your calculations.

Keep in mind that there are five important points: 
A. Starting point.
B. At the bottom of the starting hill.
C. Half way up your loop point.
D. Top of your loop point.
E. Top of your second hill.
(These points will be the theory to prove your roller coaster will work.) 

Find the GPE of the mouse ball at the top if the starting hill (Point A).

Find the Kinetic Energy of the bottom of the starting hill (Point B).

Find the GPE and KE of the following points:
A. Starting point.
B. At the bottom of the starting hill.
C. Half way up your loop point.

Using points C,D,E: You will calculate the velocity at each of those points.
C. Half way up your loop point
D. Top of your loop
E. Top of your second hill

Using points C and D: You will find the Centripetal Force
C. Half way up your loop
D. Top of your loop

Using point C and D: You will find the Gravitational Force
C. Half way up your loop
D. Top of your loop

IV. Building your Roller Coaster Model 

      a. You should be ready to start buliding your roller coaster model. With the help of your calculations and model sketch you will gather all material needed and cut and structure it to meet your original design. History of building roller coasters.
1. Pick an area in the classroom where you can work together throughout your project.
2. Choose your materials: You may research on suggested materials. Several materials such as will be provided in class. However, feel free to bring you own materials from home (must be safe, approved by teacher and at your own cost).

3. Communicate with your group members (using Wiki Spaces) and choose a duty (responsiblity) for each one in order to ensure that everyone is on task, participating and cooperating. 
4. If you will paint your roller coaster, make sure you know which kinds can stay on your roller coaster stationary. Take a look at types of paints and when to use them.
