= = =THE MOUSETRAP CAR PORTFOLIO =

**OBJECTIVES **
Our main objective is to build a mousetrap car, specifically designed for long-distance travel and design. In doing so, we will also learn about engineering cars and the different systems that it is composed of. Another one of our motives would be to study movement and how certain types of modification can improve the efficiency of our car. Through the processes of building, thinking and exploring, we should not only gain knowledge, but also have FUN. hi! **MATERIALS**
 * The mousetrap is used to power the vehicle.
 * Styrofoam or box will be used for the body of the mousetrap. Styrofoam is light enabling the car to move easily. The box would also be light.
 * The wheels are made of recycled compact discs.
 * The level arm is made of wood chopsticks and glued to the string. String that is light and can easily be adjusted or winded for an easier and smoother car movement.
 * Wheel axles are made of wire and then cut appropriately for the size of the car.
 * For the outer look of the car, we will use decorative materials and different colors of paint.

 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%; line-height: 23px;">we are not too sure which way to put the mousetrap.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%; line-height: 23px;">we may use either a box or wood to make the car.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%; line-height: 23px;">we need to decide on what the level arm and string should be made of.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%; line-height: 23px;">our wheel axles are now made of wood, instead of wire.


 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%;"> we still don't know where to put the mousetrap. in fact, we haven't gotten to that.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%;"> we are definitely using wood for the car.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%;"> we've pretty much got the level arm and string down pat.
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%;"> and the back wheel axle is in place!
 * <span style="color: #fd44c5; font-family: 'Comic Sans MS',cursive; font-size: 120%;"> by the way, the car is rear-wheel drive.
