  2. Explanation of the Design Challenge The challenge is to create a car out of all edible material. It must be able to roll down a ramp placed at a 30 degree angle. You must try to create the car so that it can travel the farthest distance and win the class competition and later go on to the final compotion and represent the school.

  3. Prototype/Rational I based my design on its weight. I believe that the more weight added will create the most speed. So I tried to make my design sturdy and heavy. I made it out of cookie wheels, pretzel sticks witch are the axils, gum drops for the rims, jelly beans that are tuck together by flower and water. Also a gram cracker is used for the base and mash mellows at the bottom for cushioning. My design was constructed so that is has more speed. I tried to finds foods for my wheels that will create less friction. I made sure that the middle part between the axil and the base was wide enough for it to spin. So my design was created to be fast and create less friction.

  4. Experimental Design Problem Question: What is the Affect of the Weight of the Car on the Distance it Travels? IV: the weight pf the car. DV: Distance the car travels. Experimental Groups: 10,20,30,40,50 jellybeans Constant: Weight (mass) Hypothesis If the weight of the car increases than the distance that the car travels will increase because there is less potential energy.

  5. Materials/Procedures • Procedures: • First place the ramp at a 30 degree angle. • Next place 10 jellybeans on the car using the sugar wax and roll it down the ramp. • Than measure the distance the car traveled. • Than repeat steps 2-3 5 times adding ten jellybeans each trial. • Material: • 2 pretzels • 1 gram cracker • 2 lifesavers(candy) • 2 Marshmallows • 8 cookies • Sugar wax to stick everything together • Jellybeans

  6. Conclusion What is the Affect of the Weight of The Car on The Distance it Travels? I found that the weigh did not affect the movement of the car because it could not move. My hypothesis was if the weight of the car increases than the distance of the car will increase because there is less potential energy. It was refuted because there were no changes in distance. It remained at 0 centimeters.

  7. Final Design Gram cracker base Rational My design was built so it can have speed. I constructed my final design so it can be lighter. When there is more mass there is more inertia. So I created a design so there is less inertia and it can travel a longer distance. Pretzel sticks Cookie wheels Jellybeans

  8. Final Design Data Table What is The Effect of the weight of the Car on the Distance it Travels?

  9. Reflection Question • My design was more affective than my prototype. • That the flour and water does not stick good. • I tried to keep the degree the ramp was placed at. • I would make changes to my final design adding wheels made of squash. • That it could not be created out of whatever food I wanted. • Making the Wiki.
