Thrill Ride - Roller Coaster

Do you have what it takes to be a roller coaster designer? Let's find out. You can either work by yourself or in groups up to 4 students. Your partners should be people you can get together with on your own either after school, on the weekend, etc. They can be any of 8 th grader from any class. If you have a friend you would like to work with in any other 8 th grade science class, they are allowed to participate. They may see their teacher for specifics about how the project will affect their grade. Here are your guidelines.

Create a roller coaster and be prepared to demonstrate it to the class. In order to earn full credit it must…

  1. Have a starting height of at least 100 cm above its base. (1)
  2. Have the track touch the base at some point during the ride. (2)
  3. Have the coaster end safely at the end of the ride at least 10 cm above its base. (3 and 4)
  4. Have at least three “creative” turns, loops, spirals, hills, etc.(5,6,7)
  5. Work at least 3/5 trials.
  6. Use a standard size marble as its cart or passenger (1 cm diameter glass marble). Check your marble against mine to make sure you have the right size. The marble must be glass so our masses are about the same. (8,9)
  7. The marble must not be forced at the start of the coaster. The energy it receives to complete the track must come from the coaster's design. No electronic or mechanical devices can be used to launch the marble. (10)
  8. Suggestions for materials can include: paper towel tubes, craft sticks, straws, old hoses, yogurt cups, etc. If you buy materials such as tubing, then the cost can be no more than $20 for the WHOLE Group! (Include purchase receipts in journal!) In honor of Earth Day, 50 bonus points will be awarded for projects that use no purchased or recycled tubing. (I can't determine if tubing is recycled or purchase…so No tubing at all for the extra credit.) In other words, the project is made entirely out of regular trash. (11)
  9. No coaster sets can be used to build the coaster. However, Legos, Knex, etc can be used for at least part of your structure.
  10. Entire structure must be able to fit on a standard size piece of poster board (2'x3').
  11. Students must remove their project to keep the grade on it. We simply don't have the dumpster space. If I must break it down and dispose of it then I will “charge” a disposal fee of 50% off the project's score.

2. Your team must keep a journal throughout your project. Describe what you worked on each day, what type of problems you had, what you did to fix the problem, descriptions of testing the coaster and adjustments you had to make. Include any receipts for merchandise purchased for the project, who worked on the project, hypotheses, data, pictures, etc.

Be prepared to explain where on the ride Newton 's three laws are demonstrated. You must be able to identify the potential and kinetic energy throughout the ride as well. (Presentation)

Make a poster illustrating your new ride with Newton 's 3 laws, potential energy and kinetic energy labeled. Also include the average velocity a passenger would travel when riding your coaster.

If your preference is using technology… A PowerPoint that combines the journal, presentation and poster information can be substituted for the requirements 2-4.

You coaster should have a creative name clearly displayed along with the identities of it's designers.

Your project should have a creative theme. This is what makes your project fun!

This is the rubric I will use to score your project. Use it for yourself so you know what to expect when I look at your project!

Journal:

This journal reflects a thorough understanding of the project and the science process skills they had to employ to reach their success. (30 pts)

A complete documentation of the project from start to finish including diagrams, test data, modifications made during the experiment, contributions by all members, and receipts for materials. This journal reflects the science skills they employed to reach success. It may not be as neatly organized or appealing to look at. (24 pts)

Some documentation of the project from start to finish including diagrams, test data, modifications made during the experiment, contributions by all members, and receipts for materials is provided. This journal is somewhat incomplete and lacks clarification of the science skills they used to complete their project. (19 pts)

Poor documentation of the project from start to finish including diagrams, test data, modifications made during the experiment, contributions by all members, and receipts for materials. This journal is incomplete and shows little use of science process. (10 pts)
