Ms. Carrera's  Technology Class

Design Process: 

Understand the Problem:  

Create a CO2 dragster following strict specifications to compete for design and speed.

Follow the Dade County Fair and Exposition Rules

Research: 

Science of Speed movie and website

Dr. Zoom dragster design movie and handout

Measure example cars to learn requirements (graded handout)

Whitebox Learning digital car design and tests.

Brainstorm/Thumbnails:

Start a list of ideas. Sketch as you brainstorm. 

Create at least 3 sketches. These will be graded.

Rough Sketch:  

Full size working drawing. USE PENCIL

Measure it against the requirements and change as needed.

Make a copy using the light table:

1. turn in one copy and the measuring handout for 2 grades.

2. cut the other copy and tape to the wood blank. This working  drawing will be used to cut your car.

Prototype:  

Weight your car, decide if more wood should be removed to get near the minimum weight.

Put the test wheels on and test it. Complete the handout.

Sand, seal and paint your car following procedures.

Install your permanent wheels, etc. Your finished car is your prototype.

Test and Improve if necessary:  

We did this with the prototype before we painted it so you could change it easily without having to repaint. Most necessary changes should be done already but test your car again, see if it rolls properly and make any necessary adjustments.

Final Presentation:  

Take a picture of your car and save  it to the class project folder with your name and keyword.
