Mousetraps:

  • You can use as many mousetraps as you like, as long as all are being used.
  • You receive more points if you can devise a way to use over one mouse trap effectively on your car.
  • NO RAT TRAPS!

Manufactured Parts

  • This project should be made of recycled materials as much as possible.
  • You should not spend more than $1.00 on your project. (including the mousetrap)
  • You should not use any parts which were originally intended for use on a car:  wheels, bodies, etc.
Back to Top
 

Improvised Wheels

  • You should try to use additional recycled materials for you wheels.
  • Good wheels can be made from:  CDs (those free AOL ones work well!), records, jar lids, thread spools, cardboard, the sky's the limit.
  •

Extends body shape beyond mousetrap

  • Your car must be made from more than a mousetrap with wheels attached. :)
  • Your car must have a body to which the mousetrap is attached.

Axle Shape

  • You need to have an axle on both pairs of wheels for full credit
  • Axles can be made from pencils, pieces of wire coat hangers, straws... anything which can go through the body of the car and turn freely.
  • You will be attaching the string from your mouse trap to one of your axles so be sure you have a plan on how to do that.
Back to Top

Originality

  • Your need to try to be original.  Think of a theme perhaps.  EX:  If you are really into baseball, use baseballs for the wheels, and a piece of an old baseball bat for the body.  Paint and decorate.
  • Think of an original design.
Back to Top

Decoration

  • Again, choosing a theme will make decorating a lot easier.
  • In the past, students have had problems when they decorated their cars.  They work perfectly before they are painted or decorated and then fail afterwards.  You might want to paint the pieces of your car separately, then put it together.  This seems to keep the failing down to a minimum.
  • Remember the original decoration of the item you use cannot be considered your final cars decoration:  EX: you use Pepsi cans for wheels. You will need to paint them or cover them.  The Pepsi colors cannot be considered the final decoration.

Traction

  • Your car have traction on all four wheels during the car show.
  • The traction can be removed for racing, if necessary.
  • Good things to use for traction include: rubber bands, balloons (stretched over the wheels), other rubber items which you might find laying around the house.
Back to Top

Device for Distance

  • Your car needs to have a device, usually a rod (like a pencil) or a U (often made from coat hangers) attached to the mousetrap.  This device helps the mousetrap go further.
  • The device actually slows down the movement of the trap arm so that you can get more movement out of your wheels without them spinning.  The problem is, if the arm is too long, then it sticks.  You need to play around with it to really see which works the best for you.
  • You can check out the link page: <mousetrap links> or ask me in class to see the examples.

Distance

  • We will be racing outside on the bus ramp.
  • You will need to place you car such that the front wheels are behind the start line.
  • Distance is measured by how far you can move your entire car.  Therefore, the distance is measured by where the back wheels of the car stop.
  • You want to move at least 2 meters for full credit!
  • If it goes over 3 meters, you have an extra 10 pts.!
Back to Top

Rubric

  • Part of your grade is being responsible enough to not lose your original rubric.
  • You will need to turn in your rubric with your car on the day of the car show.
  • Not having the original will cost you 10 points.
Back to Top

$1.00 Rule

  • Your should not have spent over $1.00 on your car, including the mousetraps.  (If, however, you had to spend more than $1.00 in order to purchase more than 3 mousetraps this rule is modified)
  • These small 5 points mean that you can prove you did not spend more than $1.00.  It is usually obvious based on the materials which you car is made from.  You can also get a parent statement if you are using materials which seem new. :)
