marble Roll 

PURPOSE: Students will observe and record the amount of work done by a marble rolling down an different height inclined planes and hypothesize about the reasons for the differences. 

OBJECTIVES: 

 Discover the higher an object is raised, the more energy is stored. 

 Measure the differences in centimeters. 

 Compute the average distances. 

 Make predictions, record observations, and create hypothesis. 

 

MATERIALS: 

1 average size marble, inclined plane*, ruler, milk carton. 

*NOTE: The inclined plane can be constructed using a piece of wood and books, boxes, or bricks to raise one end of the wooden ramp. 

PROCEDURES: 

Pre Lab Questions: 

1. Define work? 

2. What is mechanical energy? 

3. Where would the marble have the most mechanical energy? (at the top, bottom, or middle of the inclined plane) 

4. If the marble is located at the top of the inclined plane, would it have energy? Why? 

5. Where do you think the marble has the most PE (at the top of the 50 cm incline or the 25 cm incline)? 

6. Which incline allowed the marble to do the most work? (Hint: look at the distances that the marble pushed the milk carton.) 

Part A 

1. Set up the inclined plane with one end raised 50 cm from the top of the table or floor. 

2. Cut the top off the milk carton to create a basket to catch the rolling marble. 

3. Place the milk carton at the bottom of the ramp with the open part positioned so that the marble can roll into it as it leaves the ramp. 

4. Mark the initial location of the front end of the carton. (NOTE: try to position the edge of the milk carton so that it is aligned with the bottom end of the ramp. 

5. Roll the marble down the inclined plane so that it leaves the ramp, enters the milk carton and pushes it. 

6. Measure the distance that it moves the carton. 

7. Repeat five times and take the average distance. 

 

 

8. Create a data table to record your data for Part A. 

 

Part B 

9. Set up the inclined plane with one end raised 25 cm from the top of the table or floor. 

10. Place the milk carton at the bottom of the ramp with the open part positioned so that the marble can roll into it as it leaves the ramp. 

11. Mark the initial location of the front end of the carton. (NOTE: try to position the edge of the milk carton so that it is aligned with the bottom end of the ramp. 

12. Roll the marble down the inclined plane so that it leaves the ramp, enters the milk carton and pushes it. 

13. Measure the distance that it moves the carton. 

14. Repeat five times and take the average distance. 

15. Create a data table to record your data for Part B. 

 

ANALYSIS: Compare your predictions with your outcomes. 

1. Which incline gave the marble the most energy? Why? 

2. What would happen if the incline was raised to 75 cm and the marble was let go? Why? Try it to verify the prediction you made. 

3. What are some examples of storing and using energy in our environment? 

4. What factor tested in this experiment directly affected the amount of work done on the milk carton?
