Marble Run Model
Marble Run Model
Science and Engineering Practices: Develop a model to describe phenomena. MS-PS2-2: Provide evidence that the change in an object's motion depends on the sum of the forces on the object (the net force) and the mass. **Project focuses on forces of gravity, friction, and inertia

Design and Plans
Proficient
Marble run design demonstrates an understanding that a change in the object's motion depends on the sum of the forces of the object.
*Model should provide an increase in friction to oppose the marble's motion; shallow ramps to slow the downward pull of gravity; and possibly additional ways to slow the marble down, decreasing the marble's inertia.
Needs Improvement
Marble run design demonstrates some understanding that a change in the object's depends on the sum of the forces of the object.
*Model includes only one way to slow the marble's motion (either increasing friction or working against the gravitational pull of the Earth).
Warning
Marble run design demonstrates a limited or weak understanding that a change in the object's depends on the sum of the forces of the object.
Participation
Proficient
Active participation in the group contributed ideas that were demonstrated in the force concepts included in the design.
Needs Improvement
Participation in group was inconsistent and/or sometimes off topic, but still contributed some ideas that were demonstrated in the force concepts included in the design.
Warning
Participation in the group was limited and often off topic. Little to no ideas were contributed and demonstrated in the design.
