8 How to Start Designing

Things to note:

• Everything is posted on schoolsoft and on the blog: http://www.science8velji.wordpress.com

• The highest point on your roller coaster should be the STARTING point.

As you are working, ask your teacher for help, advice, and

feedback!

What’s the story: Dear IESS Designs, SmileCorp has built a chain of amusement parks across the country over the last 30 years. In order to be competitive we are always looking for ways to keep the rides and attractions at our parks new and exciting! With this in mind we have decided to build a new roller coaster at our largest and oldest park. We would like you at IESS Designs to come up with designs. Each design team should build and test a scale model of their design. A team from SmileCorp will visit IESS Designs to hear a proposal from each design team. The best design will be built and featured at our park. Research from our marketing department indicates that the following criteria are crucial to the success of a new ride: -Thrill factor -Theme However, we don’t have unlimited amounts of money and don’t want to be sued if any riders are injured! Therefore the other criteria that we at SmileCorp consider crucial are also -Ride safety -Construction cost Naturally we will be expecting each design team to address these 4 criteria in their design process and explain their reasoning in their presentation. Materials to build scale models will be provided by SmileCorp. Outside materials may be used but they must be accepted and the cost to the design approved by a SmileCorp representative or the president of IESS Designs. Design Criteria Thrill factor - theoretical and real calculations of potential and kinetic energy and velocity and acceleration Theme -creativity and aesthetics - scale model design Ride safety -must prove that ride will not injure riders Design cost - list and price all materials used (a price list for materials provided by SmileCorp will be provided)

Materials Cost:

Tubing/track (u-shaped:cut in half) 100,000 kr/m

Skewers 30,000 kr/m Toothpicks 500 kr/m Wire 1,000 kr/m Glue stick 500 kr/m Wood glue 100 kr/m Construction paper 500 kr/m Plastic wrap 1,000 kr/m Aluminum foil 5,000 kr/m Pipe cleaners 500 kr/m

What you will need to do:

1. Design a roller coaster (PAIRS / INDIVUDAL) - Make a blueprint / design (ritning) of your vehicle including a scale and a list of materials - You will have 3 lessons to work on your project design.

2. Construct and test your design (PAIRS) - You will have 4 lessons and homework to work on constructing your design and testing it

3. Perform some physics test that find that analyzes the speeds, energy changes, and motion in your roller coaster. (Test in pairs, write up individual)

4. Final Evaluation (INDIVIDUAL)

- You will do a sales presentation (säljargument) to Smilecorps. You can present using a poster, an essay, a brochure, pretty much anything creative and awesome. (See the “story” and the grading criteria) You will need to answer all the parts required by the write up (see the check list)

If, for the write-up, your work is too similar to your partners, I will consider this the same as copying and lower your grade

Checklists:

Design

o Make a drawing / blue print of your model BEFORE building that has:

- Scaled drawing with measurements (G) (pairs)

- Labels of the parts (G) (pairs)

- Description of what materials all the parts of the roller coaster will be made of (G) (pairs) and

o why � scientifically (VG) (individual)

- Description of the design of your roller coaster and why it is that shape � scientifically (G/VG) (individual)

o Bonus cool points for creativity & theme

Prototype

o Make working model rollercoaster (G) (pairs) and a description of HOW you built your rollercoaster (G/VG)

(pairs)

o Build the roller coaster mostly on their own and do it following safety rules (VG) (pairs)

o ‘Test your prototype’ and suggest improvements (VG / MVG) (Write up is individual)

For example, did it go around loops? What did you do to improve your roller coaster? What were some

problems with the roller coaster as a whole? How can you fix them?

Evaluation (all done individually!) o Because a roller coaster is a type of vehicle, talk about the development of the vehicles (fordon) in both the

past and present. Include a short description about the history of roller coasters (G)

o Give some examples of why we needed this technology (G)

- Relate to how have changes in the types of vehicular transport (over time) changed with the development

of society (VG)

- How have changes in the types of vehicular transport (over time) affected society as a whole? Affected the

environment? (VG)

o How realistic/expensive/environmentaletc is your roller coaster (Both positives and negatives) (VG/MVG)

o Improvements or alternatives to parts of your design. For example if your track was made of rubber, is there

an alternative you could have used? Why? (MVG)

P a g e | 7

Physics Tests (Tests done in pairs, analysis and write up are done indivudally) o Shows how long the track is (distance), how long it takes for a marble / ball to run through the roller coaster

(time), and calculates speed of the ball (G)

o Shows how much potential energy and kinetic energy the ball has at different points on the roller coaster

track (G)

o Compares how this energy and speed would be experienced in reality (on a full sized roller coaster) (VG)

o Analyzes the safety of these speeds and changes in energy and discusses how to make them safe and

reasonable (MVG)

o Explains the motion of the ball during the course of the experiment (speed, changes in energy, forces that

would cause it to lose energy and speed, etc). (G/VG)

o Analyzes things that would have caused error during tests (of the physics) and how they can be improved

(MVG)

o Plans further research, experiments, or tests that could be done on the roller coaster (MVG)

All research should have sources / references.

Design a roller coaster When thinking about designing something it helps to first do some sketching and idea exploration. When doing this, try using the following to help guide the design process:

1. What is the purpose of the item? How is it going to be used? 2. What material should it be made from? 3. What is its shape, inside and out and from all angles? 4. Do certain parts of it need to be different? 5. Can the object be made using just my design as a guide? 6. Can my design ideas be used to sell the object? 7. Are my ideas about the design supported by science?

• First take a large page to

record your ideas. Explain in words and pictures what you are thinking about the design of the object.

Next, make detailed design drawings that are to scale.

Labels of the parts of your vehicle

Add a description of what materials all

the parts of the coaster will be made of

(G) and why � scientifically (VG)

Write a description including purpose of

your coaster and why it is that shape �

scientifically (G/VG)

Make sure your teacher sees your design ideas as they take shape.
