Racecar Unit

The students will be using the 6 step Technological Problem Solving Method to create their very own prototype race car.  Their goal is to achieve the fastest race time.

 

 

Step 1 - Understand the Problem

   

   Students will receive their Design Challenge which is outlined in Unit 1.

 

 

Step 2 - Gather Information

  

   Students will gather information about aerodynamics, drag, and friction.

 

 

Step 3 - Develop Solutions

 

   Students will use the information they gathered, along with the project specifications to to create a solution and design sketch.

 

 

Step 4 - Implement a Solution

    

   Students will build their prototype race cars.  They will use the drill press to drill their axle holes and the scroll saw to cut out the body of their car.  Next students will use a wood rasp/file to finish shaping their cars.  They will use sandpaper to reduce skin friction.  The last step is to assemble the car.

 

 

Step 5 - Test & Evaluate

 

   Students will weigh their cars, check the alignment, and test their prototype race cars on the race track.  The track is 23 feet long and uses compressed air to launch the cars down the track.  Average speeds range anywhere from 20-30 MPH. Students will evaluate their cars performance.

 

 

 

 Step 6 - Redesign & Communicate

 

   Students will look back over the process of creating their car and decide how they would redesign.  Communication is always key in sharing information and results.
