A SimQuest simulation on the physics topic of moments. Students can change the two forces acting on the persons (F) and the distances to the center of the seesaw
(a) and discover the effect on the moment (M). Support is offered in the form of an assignment that asks students
to explore the balance of the seesaw. Another available cognitive tool is a hypothesis scratchpad that lets students build
expressions from variables (e.g., force F1, distance a1, and moment M1) and relations (e.g., increases) to create
testable hypotheses (e.g., if F1 increases, then M1 increases).
The simulation was taken from a larger Dutch SimQuest simulation "Moment 2 - Balance" built by the University of Twente for publisher NijghVersluys (www.transferw.nl).
It is used as an example in the SCIENCE article by Ton de Jong (Vol. 312, April 28 2006).
