The Mousetrap Car
** My name is Kao Navapol, and I'm in Grade 7. About few weeks ago, Mr. Dan LK (our computer teacher) told us to make a model of a car which is made from a mousetrap.Mr. Dan LK told us to make a group which were Baneen and Lorand. ** **Bad News: Last Friday ( April 8, 2011 ), Baneen was gone to another school so she will not work with us anymore !**

//__Objectives__//
// The objective is to create a mousetrap car that can travel the farthest //// distance and speed. While we are making the designs, we also wonder how the mousetrap car works, what material do we need to use, how ar //// e we going to make it, and what kind of designs are we going to use. //

// And these are what we come up with: // - Mousetrap - Woods - Thick ropes - Sticks / Rods - Spring - Knot (s)
 * //__Materials That We Need for Model 1:__// **

Talking About "Model 1"
We thought that when the rope was attached to the wheels and the mousetrap, it will move faster because it pushes itself towards. Also we added spring because we thought that it will go faster even more if its hit against the wall.

Talking About "Model 2"
We thought that when the rope was attached to the CDs or the wheels and the mousetrap, it will move a little bit more faster because it pushes itself towards. Also in front of the mousetrap car, there will be a thread which it will give the force to the wheel and the mousetrap.

**Talking About "Model 3"**
We thought that when the rope was attached to the wheels and the mousetrap, it will move faster because it pushes itself towards. Actually, it is the same as "Model 1", but we think that CDs might goes faster than wood. //** - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - **//

**The Description about the Mousetrap Car** **The Mousetrap Car that we made was Model 2, and our work went pretty well. But we will find our way to develop more efforts in it. At first, we decided to use wood as our body / base of our mousetrap; but because of the splinter so we decided to use cardboard instead. Then, we put some sticks in front and back of the carboard so we can attach the mini CDs or the wheels into it, and we also think that we will put some thread between the sticks to use it as the engine of the mousetrap car. To make it stronger, we use some scotch tape. Finally but not least, the mousetrap will be place nearly at the end of the body / base, and use some more sticks to attach the thread to the mousetrap to keep it running. When we push the stick to the plac****e where we put the thread. It will push itself toward and make it running. But there is one condition: It will loses its power quite fast!** ===Finally, we think that "Model 2 " is the design that I am going to choose / make / test. === >
