Go to http://www.docfizzix.com/how_work.htm  and answer these questions:

• What is Doc Fizzix's definition of a mousetrap powered car?
• What does he say the string pull is?
• In which direction must you wind the string if you want the wheels of the car to go clockwise?
• What can happen if the mousetrap is located too close to the drive axle, according to Doc Fizzix?

Go to http://www.docfizzix.com/distance_pics.htm  and answer these questions:

• What is Doc Fizzix's definition of inertia?
• If you build a heavy car, will it have more inertia than a lighter car?

Now go to http://senior.billings.k12.mt.us/mouset/fall98/index.htm  and look at the pictures of mousetrap cars and the distances that each acheived.

• Which distance was best?
• Which was the worst?
• Compare the best and worst cars by giving at least two differences between them.
• Choose the car that you like the best.  Make a rough sketch of it on the blank side of  page1.  Put in any notes that may help you when you design your car.

Go to  http://www.s-hamilton.k12.ia.us/science/m_trap/race.htm  . 

• In this Industrial Technology class, what was the approximate distance that won the trophy? 
• What did these students do to provide traction for their cars?
• Please look at the pictures for ideas.

Go to http://www.faribault.k12.mn.us/startpages/fms/home/team603mouse/ and, on the other side of this paper, draw a rough sketch of the design that appeals to you the most.

Go on to http://www.sdhc.k12.fl.us/~middleton.magnet/yes/mouse.htm  .  On the other side of this paper, make a rough sketch of the car pictured.  Use any notes that may help you in your car design.

Finally, go to http://www.msu.edu/user/fawcett3/Zeeb.htm and scroll down to CONCLUSIONS. 

• What does this student say are the two most important things in making a good mousetrap car?
