Summit Stock Cars

Design Challenge:

To design and construct a three or four wheeled vehicle. It will be launched down a ramp onto a flat surface, where it will travel as far as possible.

Top distance 81 feet 6 inches (paper wheels)

Top distance 106 feet 6 inches (2 CD, 2paper wheels)

Procedure: 1 + 2

• 1.     Create your race team. (A team can consist of either four or five members.)

• 2.     In your teams come up with a design for your team logo which will be shown on the side of each of the team cars.

Procedure 3

• 3.     Create a racecar ideation sheet, consisting of five possible racecar designs. Keep in mind that it must be possible to create your racecar using the fold out construction method. You must then choose your best design and have the instructor review your design for practicality.

Procedure #4

• 4.     Design a concept sketch of the side of your car. This drawing is to be 1:1 scale. Use a ruler and a pencil. Show the number of grid dimensions that you will be using. You must have a flat (horizontal) line at the highest point of the car.

Procedure 5-7

• 5.     Layout your final design on the graph paper provided, using the vehicle fold out construction method, a ruler, a pencil and a compass.

• 6.     Glue the grid paper pattern to the card stock and cut out the vehicle.

• 7.     Make the appropriate folds that will give you the three dimensional racing vehicle you designed.

Procedure 8-10

• 8.     Glue the folding corners• 9.     Add the wheel and axel assembly.• 10. Add weight to the car and “test and

tune”.

• Test and tune is your chance to experiment with the amount and location of weight to obtain the greatest distance.

• Min/ Max Length 30-36grids

• Min/ Max Width 9-16 grids

• Min/ Max Height 6-12 grids 

     Total of Width and Height may not exceed 48 grids

• Width x 2 = a• Height x 2 = b

a + b = total grids (max 48)

location     Wheel base (how close

the axels are form each other

     Length of axel     Number of wheels

(may have either 3 or four wheels)

Materials

     Drafting paper, card stock

     Plastic straw bearings

     Wood axels

     Teflon washers

     Various glues and tapes

     Weights = metal washers or anything you have 

Race Testing

    Drivers will test their own vehicles for the best performance.

    On race day each driver will have two runs: the best scores to be recorded.

/10 

         This mark is based on a performance scale. The cars that receive the greatest distance will receive 100%. The next cars that roll the greatest distance will receive 90%, and so on. The shortest distance possible will be a default distance of 8-10 feet.   

        Students will evaluate their own car. Learning to be critical and honest about their work is important to the understanding of their mark. This way the students learn to recognize their successes and areas that should have been improved. Note: The teacher then marks the project. (teacher has final say)
