The Roller Coaster Project Webquest

Wanted! Roller Coaster Design Team!

Congratulations! You have just been commissioned to design a roller coaster for the Honiss Amusement Park. The Board of Directors feel that a new, thrilling roller coaster is just what is needed to improve attendance and thus increase the profits of the park. They want you to design a rollercoaster that will be the "king of the park".

The Task

Your mission is to design a roller coaster that has at least one Loop and three hills. In trials of a model of your design, a marble placed at the start of the roller coaster must successfully navigate the entire roller coaster with out stopping and/or receiving outside power. In order for your design to be approved by the Board of Directors (your teacher), you will need to submit the following items:

  1. Partner Selection form. Due 1/3/08
  2. A list of roller coaster building materials your group has chosen to use. Due 1/7/08
  3. Submit construction plans, theme, and a sketch of your roller coaster. Due 1/14/08
  4. Journal. Due 1/22/08
  5. Submit photos of your group's roller coaster model. Due 1/30/08
  6. Create a 3-dimensional model of your roller coaster. Due 2/6/08
  7. Create a multimedia presentation to "sell" your design to the Board of Directors (your teacher). Due 2/6/08

The Process

You will need to complete the following steps to accomplish this task:

  1. Meet with your team. Decide what responsibilities each team member will have.
  2. Start a journal to record information, thoughts and ideas. Start with brainstorming ideas about what you already know about roller coasters.
  3. Write a list of questions you might need answered in order to design a "king of the park" roller coaster.
  4. Research the history of roller coasters in America and the various successful roller coaster designs used in many amusement parks today.
  5. Brainstorm ideas about the design you wish to create for your roller coaster.
  6. Decide on a design and create a construction plan and a sketch of the roller coaster. Remember to decide on a theme and a name for your roller coaster. Bring both of these to the General Contractor for suggestions.
  7. Build a 3-dimensional model of your design (Due Feb. 6th - 8th).
  8. Test your model to see if it meets the criteria set forth by the Board of Directors in "The Task".
    • If your model does not meet the criteria, repeat steps 6 thru 8 until it meets the criteria.
    • If your model does meet the criteria move on to step 9.
  9. Plan and create a multimedia presentation to the Board of Directors (your teacher) to "sell" your design.
  10. Present your multimedia presentation to the Board of Directors.

Learning Advice

Working as a Group

You must remember that it is very important to use your time wisely. This is a team effort and it cannot be completed successfully unless all members of the team respect each other and work together to make their project the best. Remember to use the project journal to record all information, discussions, ideas and trials.

Gathering Information

Remember to title each page of your journal. Try to limit the number of different ideas on a page. If you must put more than one idea on a page, separate the ideas with a thick line and title each different idea. Be sure to use a variety of resources. Do not limit yourself to the links provided in the "Resources" section. Use books and interview people about their own personal experiences with roller coasters.

Creating a Multimedia Presentation

Remember to use the principles of good design when creating your presentation. The main purpose of this presentation is to convince the Board of Directors that your roller coaster is the one they should build.


Use these questions to make sure you a complete, well done project:
  1. Do you have all of the parts of the project completed: a name and theme for your roller coaster, your journal, construction plans and sketches, your 3-dimensional model, the results of your trials, and your multimedia presentation?
  2. Is your presentation convincing as to why your design should be picked as the new roller coaster for the Honiss Amusement Park?
  3. Did you explain why you designed your roller coaster the way you did?
  4. Did you work cooperatively with the other members of your team? Did all members of the team contribute equally?
  5. Does your multimedia presentation follow the rules of good design? Is it interesting? Will it catch and hold the attention of your audience?


  1. What was one thing you did during this activity that you think you will remember six months from now?
  2. If you could change one thing about how you participated in this assignment, what would it be?
  3. What are you most proud of in this project?
  4. How did you organize the information you researched? Was it an effective method? What could you have done differently to make it more effective?


In completing this project, you have explored the physics of rollercoasters. Based on this and what you heard from the other presentations in class, what did you learn about how rollercoasters work and what makes a rollercoaster a "king of the park" ride?

    Newton's 2nd Law - Force, Mass, and Acceleration

    Link1. GO TO:

    2. Fill in the blanks:

    If a bowling ball and a soccer ball were both __________ at the same time from the roof of a tall building, which would hit the ground with a __________ force? Common sense tells us that the __________ ball would. We know that _________ accelerates all objects at the same __________, so both balls would hit the ground at the same time. Therefore the _________ in forces would be caused by the different __________ of the balls. Newton stated this relationship in his __________ law, the _______ of an object is equal to its ________ times its ______________. A karate master can exert a tremendous ________ by utilizing years of training, proper technique and focus. Although a human hand and forearm may have a _________ of _________, with proper technique, a karate sensei (master) will be able to use his entire body's __________ in breaking bricks. Combining a possible mass of 70 kg and an ___________ of 50 ______, this master will exert __________ of force, well more force needed to break several bricks. A ___________ bullet and a slow moving ________ both have tremendous force. The force of the bullet can be

    ____________ to its incredible ___________ while the force of the train comes from its _________ _________

    3. Identify 4 other occurrences where Newton's 2nd Law may apply.

    4. GO TO:

    5. Fill in the blanks:

    E = mc2 may be the most famous equation in physics, but Newton's second law ____________ is the most important. The second law ____________ force and acceleration — and incidentally keeps planets in their ____________ around the Sun. Before unleashing the second law, let's make two useful observations. First, it is intuitively clear that a ____________ force produces a ____________ acceleration. For example, two pro wrestlers ____________ on a stalled car will get it going ____________ than just one could. Second, ____________ or mass is somehow involved. Those two wrestlers would need to use more force to push a ____________ than to push a Volkswagen ____________.
    In fact, Newton realized that for a given force F, the ____________ the mass of the ____________, the smaller its acceleration. Thus, ____________ second law can be expressed concisely as follows: ____________.

    7-1 Characteristics of Living Things - Discussion Question

    We have spent the past week learning about the characteristics of living things as they pertain to animals in the wild. What we have not discussed is the fact that humans are also part of the animal kingdom and we have developed certain characteristics that have made us one of the most successful species on earth.

    Identify and explain some of these characteristics. How may these characteristics impact the earth both positively and negatively.

    You may post your thoughts to this question as a response directly on this blog or you may write them down in your notebooks.

    Characteristics of Living Things - 7th Grade


    All living things share certain characteristics. In this activity you will investigate how one particular animal displays these characteristics and how these characteristics help that animal to survive in its environment.


    All living things share the following characteristics. Living things can:
    1. Move
    2. Metabolize (including eating, digesting, and excreting)
    3. Grow and develop
    4. Respond to the environment
    5. Reproduce
    6. Adapt to the environment

    The special way that each organism exhibits these characteristics makes it suitable for a specific environment. Organisms can survive only in certain environments because of their particular characteristics.


    Pick an organism that interests you. Research, using the Internet, Nature or Encarta encyclopedia, and other library resources, how that animal shows the 6 characteristics listed above and how these characteristics help this animal to survive in its environment. Present your information in a PowerPoint slide show.


    Answer as many of the following questions as possible while doing your research, and then incorporate them into your report/slide show. (Note: Each of the topics must be included, at least briefly, in your report.) Feel free to include other things under each topic that may not be mentioned.

    1. Move – How fast does this organism move? Does it tend to move for short periods of time or long periods of time? When is this organism the most active? Does this organism migrate?
    2. Metabolize – What does this organism eat? How much does this organism need to eat? How often does this organism eat? How does this organism’s digestion work? How does this organism excrete waste?

    3. Grow and develop – How long does it take this organism to reach maturity? How long does this organism usually live? Who takes care of the offspring? How do the offspring learn? Does this organism undergo any metamorphosis?

    4. Respond to the environment – What does this organism do when faced with danger? Does this organism have a territory? How is this territory marked and protected? How does this organism protect its young? How does this organism get along with others of its kind?

    5. Reproduce – How long does it take this organism to reproduce? How many offspring are born at once? What kind of reproduction does this organism use?

    6. Adaptations – How do the characteristics that this organism displays help it to adapt and survive in its environment? Does this organism have special features to help it survive?

    7. Extinction – What things could happen to this organism to cause its extinction? Does this organism have special needs that may not be met in the future? Could this organism be moved to another location to help it from becoming extinct? What things would need to be considered if this organism were moved to a zoo or other artificial environment? What precautions should humans take to ensure the survival of this organism?
