2. Title: What Variables Will Allow a Marble to Roll Down a Tube and Travel Only 50 cm. From The End of The Tube?

3. Background: What knowledge do you bring to the problem? What do you know about marbles? What do you know about inclines? What do you know about friction? What do you know about force?

4. Hypothesis: If I raise the tube, then the marble will travel farther and if I lower the tube the marble will not travel as far because the force of gravity will accelerate the marble at greater rates as the incline gets higher. The variables that allow the marble to roll down a tube and travel 50 cm. are the raising or lowering one end of the tube (called the… variable) and the distance the marble rolls as a result of raising or lowering one end of the tube (called the … variable).
