Oscillations 2 Background Information on Simulation Created for Lesson 2: Romeo and Juliet: In Rapturous Oscillation?

CrossCurricular 

The model used in this lesson is structurally similar to the springmass simulation (Lesson 1) and is intended to follow it. It challenges students to apply what they have learned about springs to intangible subject matter. For example, “resistance” from the spring simulation gets recast as “fatigue” to show what happens when one party in a relationship gets tired of the upanddown dynamic. Students should recognize that their own personal relationships include themselves as part of the system; therefore, they do have the opportunity to influence an unwanted dynamic.
Complex Systems Connection: Cause within System. Five interdisciplinary areas are covered in a series of lessons, utilizing a family of models that all generate oscillation. Oscillation in realworld systems is often considered problematic rather than a consequence of system structure. This progression of lessons will help students understand that undesirable behavior can be a consequence of system structure and not a result of outside, uncontrollable influences. In other words, a system that oscillates does so because it has an inherent tendency to do so.

Oscillations 1C Springs Everywhere: Exploring SpringMass Dynamics 

Author(s):

Subject:
CrossCurricular 

The spring simulation allows students to experiment with a virtual springmass system. They can change settings, run the simulation, and compare results. The default simulation behavior is equilibrium, as the spring is initially at rest. By changing the settings, a variety of oscillatory behaviors are generated. This model is intended as an introduction for this series of oscillatory models, although it also aligns with specific math and science curricular standards.

Students explore a simple spring simulation to see how springs behave, given different characteristics. Students can change the springiness, the resistance, a mass at the end of the spring, and the amount of push or pull.

This lesson is a precursor to the Oscillation curriculum created for the Complex Systems Project. Experimenting with a virtual spring will help students gain an intuitive understanding for why a spring oscillates. This knowledge will be reinforced in other lessons in this series.

From CCSTADUS. Six models, accompanied by student work packets, which cover a variety of topics that are either difficult for many students to grasp, or are not usually taught to students identified as AtRisk. The six models are: Basic Coordinate Graphing; The Bathtub: Adventures in Linear Graphs; Changing Slopes; Parabolic Graphs; Exploring Feedback: Reservoir Control; and Population Growth and Renewable Resources. Not designed exclusively for use with identified AtRisk students.

Modeling Physics: System Dynamics in Physics Education 

Author(s):
Horst P. Schecker 
Subject:
Science 

System Dynamics modeling helps to shift the focus of physics instruction towards more qualitative learning. Dynamic modeling requires students to analyze a phenomenon and develop the model, whereby they are introduced into the strategy of expert problemsolvers, i.e. to concentrate on a conceptual and semiquantitative analysis. The modeling system supports the learner both in constructing the model and exploring its physical adequacy through simulation runs. Lead article in Spring 1996 CLExchange newsletter.
