= Mousetrap Vehicles =

// Design Brief //
=__ Introduction __= Transportation technologies contain simple machines and energy sources. In this activity, you will be utilizing simple machines and energy to propel a mousetrap vehicle.

__ Problem __
You will design a mousetrap vehicle that uses at least three simple machines. You will be required to produce 5 vehicle designs but you must have //only one// final vehicle for testing. Once you have completed the testing, you will analyze the performance of your vehicle.

__**Materials**__
1 - Victor Moustrap 1 - 3"x8" Balsa Wood Panel 4- Popsicle Sticks 2 - 1 5/8" Dia. Wheels 2 - 1 3/8" Dia. Wheels 2 - 8" x 1/8" Dia. Dowel Rods 2 - Rubber Bands 24" of String 4 - 1/4" x 1/4" x 8" Balsa Strips 3 - 1/4" x 1/4" x 3" Balsa Strips 1 - 12" Brass Rod =__ Design Parameters __= You will be evaluated according to the following criteria. TOTAL - **70** POINTS // See the rubric for an explanation of how the points are assigned //
 * 1) The energy source must be one mousetrap.
 * 2) You must use the mousetrap provided by the teacher.
 * 3) You are __not__ allowed to use any other sources of energy besides the mousetrap.
 * 4) The mousetrap must be transported with the vehicle.
 * 5) You may __not__ alter the spring of the mousetrap (i.e. adding extra turns).
 * 6) You must complete three test runs.

 * 9) Materials list and price sheet
 * 10) Final drawing sheet
 * 11) Testing and calculation sheet
 * 12) Student evaluation sheet
 * 13) Sketches of preliminary ideas (attach sheets)
 * __ Evaluation __ **
 * 1) Mousetrap vehicle 12 pts.
 * 2) Preliminary Sketches 8 pts.
 * 3) Material List 8 pts.
 * 4) Final Vehicle Drawing 10 pts.
 * 5) Testing and Calculations Sheet 12 pts.
