CO2 Dragsters

To go straight to the students web pages click here......

Every quarter my 8th grade students have the opportunity to create their very own CO² Dragsters. These dragsters are created by using numerous tools and materials. The process takes about 4 to 5 weeks and involves time management, creativity, design skills, wood working, knowledge of drag, wind resistance and how gravity effects a car (or object in motion). When they are finished each class then has the opportunity to time trial their car and be ranked accordingly for the race. Once the race begins each students has at least two chances to race. Even though we do not have the means to do a full double elimination race we do allow each student to race twice.

What follows is the process that the students go through to design and create their cars. After that links will be provided to the students who created a webpage for their car. I encourage you to see some of the creative and innovative cars that are made.

Step 1: Design

The design stage encompasses the first 2 weeks of class. During this stage the students go from 8 thumbnail sketches to a finalized drafted side view and top down view. During this stage the students learn design techniques, patience, and concepts such as drag, how weight can effect their car, and the importance of symmetry.

Step 2: Creation

During this stage of development the students trace their drawing on to a blank bass wood block. After cutting it out on a bandsaw and drilling holes for the wheels the students begin sanding. This process takes about 1 to 2 weeks. Concepts during this stage are, design, basic woodworking, keeping to a timeline and symmetry. See below for sample pictures of this stage.

Step 3: finishing

The third stage involves the painting and applying the components to the cars. The painting stage is very involved in that the students must apply primer coats and roughly 4 - 5 coats of a final color. When all done they clear coat their car and prepare to finish putting it together.

Once the wheels and axles are placed on and the car has its eye screws in place the student has finished their car and is ready to race. The following are only a few of the finished cars....
