    2. Make a ramp from the meter sticks.
    3. Cut a small hole in the paper cup.
    4. Put the cup at the end of the meter stick ramp.  Face the hole in the cup
        so that a marble can roll down the ramp and into the cup.
    5. Put a marble at the top of the meter stick ramp and let it roll down the
        ramp and into the cup.
    6. Use the second meter stick to measure how far the cup moved.  Record your data.
    7. Repeat for a total of 5 trials.
    8. Add a second marble to the top of the meter stick, so that two marbles roll down the ramp.  Roll         
        both marbles together. Repeat steps 5 – 7.

        down the ramp.  Roll all marbles together. Repeat steps 5 – 7.
