1. Slow Ride Challenge Materials  Cardboard Base (42 x 32 cm)  2 Smaller Cardboard Pieces  2 Pages of Construction Paper  1 Pipe Cleaner  10 pieces of spaghetti  1 Paper Towel Square  1 meter of masking tape  2 Glue Sticks (max) - You will also get a glue gun to help assemble your design. Rules -read the fine print! Rules -read the fine print! 1. The time will be started when you release the marble at the top and it will be stopped when the marble reaches the bottom of the cardboard (42cm). 2. The marble must be moving at all times once it is dropped! If the marble stops or gets stuck, your group will be disqualified. 3. The only two forces that can affect the marble’s motion are gravity and friction. 4. You cannot use more than the provided supplies. 5. Any of the supplies can be altered EXCEPT the cardboard base MUST remain at its original dimensions. 6. The marble cannot come in contact with any glue (only the materials listed to the left can affect the marbles motion). 7. Nothing can be attached to the marble. 8. You cannot touch any of the materials once your marble is dropped. 9. Your cardboard base must be free standing with no props outside of the given supplies. 10. Your design must be approved by your teacher to be considered for the contest. 11. Ms. Ryan or Ms. Aaron can make up any new rules at any time :) Objective: Move a marble from the top of the cardboard to the bottom the slowest!

3. Slow Ride Challenge Analysis Questions 1.Calculate the Gravitational Potential Energy (J) of your marble at the top of your board. 2.Calculate the Average Kinetic Energy (J) of your marble. 3.Compare the PE and KE of your marble. In theory, they should be equal. If they are not, give TWO reasons for the discrepancy in your results. 4.Do you see any correlations between your energy calculations and the class ranks for each group? Explain. 5.If you wanted to sell your design to a very serious marble racer who was willing to pay good money for the slowest marble in all the land…how would you convince him to buy your design? Write a well constructed paragraph explaining why you think that your design will get the marble to the bottom of the board the slowest. Use ALL of the following words in your writing to convince them that yours will win. – Mechanical, Energy, Potential, Kinetic, Gravity, Mass, Force, Friction, Velocity, Acceleration, Distance, Time
