PhET Balanced and Unbalanced Forces, Net Forces, and Newtons

Balanced and Unbalanced Forces, Net Forces, and Newtons

Small groups of students will perform Force and Motion simulations using PhET programming. These simulations will show the effects of balanced and unbalanced forces on the motion of an object, and correctly calculate the net forces. The students are required to complete each 'Task' simulation and properly use the Science terms in their written answers to demonstrate mastery.

Forces and Motion
	Poor (Unacceptable) (N/A)	Needs improvement (N/A)	Good (N/A)	Excellent (N/A)
Predicted Movement	Poor (Unacceptable) The students did not attempt to predict movement on forces and motion of an object of the Task	Needs improvement The students' written prediction of movement was incomplete or not clearly stated in the motion of an object.	Good The students' prediction of movement was adequate.	Excellent The students' demonstration cleary showed the effects of balanced forces on the motion of an object.
Actual Movement	Poor (Unacceptable) The students did not attempt to perform a 'Task' simulation of forces on the motion of an object.	Needs improvement The students' 'Task' demonstration did not correctly write the effects of Task' simulation of forces on the motion of an object.	Good The students' demonstration adequately showed or wrote the effects of forces on the motion of an object in the'Task' simulation.	Excellent The students' demonstration cleary showed the effects of unbalanced forces on the motion of an object.
Sum of Forces (Net)	Poor (Unacceptable) Students did not correctly calculate the net force in any of their simulations.	Needs improvement Students correctly calculated the net force in only one of the two simulations.	Good Not applicable.	Excellent Students correctly calculated the net force in all 'Task' simulations.
Use of Science terms	Poor (Unacceptable) Students did not properly use Science terms in any of their PhET 'Task' simulations.	Needs improvement Students properly used the Science terms in only one of the two 'Task' simulations.	Good Students properly used Science terms in most of their 'Task' simulations.	Excellent Students properly used the term “Newton” in both demonstrations.
