Marble Roll Experiment

Roll a marble through the tube and into the cup.

Marble roll experiment.

The same principles apply to spheres as well a solid sphere such as a marble should roll faster than a hollow sphere such as an air filled ball regardless of their respective diameters. For this experiment all you need is a ruler with a groove in the middle and some marbles. Long cardboard tube such as an empty roll of wrapping paper to make your ramp. Record the distance travelled from the end of the ramp for each trial.

First we lined up three marbles in the middle and one marble at the edge. Add a ball or marble. The cup should move measure the distance between where the cup ended up and where the cup started out. Tip the container to roll the marble through the filler.

Observe other characteristics of and differences between the fillers and balls. I therefore disregarded the first roll 284 inches and rolled the marble a fourth time and then calculated the average for rolls two three and four. A small marble. Sometimes near the end of a roll the marble would roll sharply to the side or stop and roll backwards.

Add fillers one at a time to the bin. Blackline 2 marble roll experiment 2 record sheet 34 session 7 marble roll experiment 3 what happens if you make the ramp longer. Conduct the experiment. Release a marble from each of the five starting positions listed below.

One uncontrolled variable in my experiment was the floor because it wasn t exactly level. Popular marble experiments help students discover basic principles of. I asked the boys what they thought would happen when i flicked the marble. They thought that the marbles in the middle would roll away.

Set up the following experiment. How far did it go. Blackline 2 marble roll experiment 2 record sheet 34 session 7 marble roll experiment 3 what happens if you make the ramp longer. Carry out four trials marble releases from each starting position.
