This tutorial helps students to turn their side views of the CO2 Dragster into isometric (3D) drawings. Designers must be able to work with both types of views when quickly visualising and communicating using concept drawings. A basic grid is drawn in isometric and is used to construct the dragster in 3D.
STEM Learning Activity – CO2 Dragsters
CO2 dragsters are cars used by miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a 20 metre track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics. Two hooks (eyelets or screw eyes) linked to a fishing line on the bottom of the car prevent the vehicle from losing control during launch. In a race, senors records the time taken to reach the end of the track. Often, the dragster is carved out of balsa wood because of its light weight.
In the Downloads section below you will also find resources to support the CO2 Dragsters Learning Activity.

ME Program Endorsed Pitsco Dragster Classroom Kit
Dragsters are an exciting method to teach metrics and the design process. This Kit provides the key components and resources for you to facilitate the ultimate Dragster program at your school. An illustrated, self-directed student workbook holds the students' attention as they learn step-by-step automotive-design processes. The kit includes everything you require to craft 50 Balsa Wood CO2 Dragsters including the CO2 cartridges and student workbooks plus an array of teaching resources and 4 Dragster paint stands. Assembly requires a drill, coping saw, wood file or rasp, ruler, scissors, finish, and a race system (not included).
