Engineering flow model

Model shows forces of motion, push and pull. It shows the effects of potential and kinetic energy on an object. The design uses frictional forces to slow down the ball or marble.

Engineering Flow
	Proficient 5 pts	Needs Improvement 3 pts	Warning 1 pts
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.
Product	Proficient The device produced actually worked and completed the desired outcome. All ramps were completed successfully	Needs Improvement The device could actually work and complete the desired outcome with a few major alterations. Some ramps were completely successful.	Warning The device does not work and the desired outcome is not obtainable without restructuring the entire machine. One ramp was successful.
Marble run time	Proficient Marble/ball/water ran through the maze for 12-15 seconds	Needs Improvement Marble/ball/water ran through the maze for 5-10 seconds	Warning Marble/ball/water ran through the maze for 1-5 seconds
