Ejs Intro SpringLab Model

This inquiry-based resource asks students to develop a computer model for a mass on a spring. Designed specifically for students with no prior experience in computer modeling, the lesson opens with a hands-on lab where students investigate spring-and-mass systems, record data, and analyze results. Afterward, they use the Intro SpringLab computer modeling tool to build their own model of a mass on a spring. Finally, they compare the results of their computer models with the real-life results obtained in the lab.
Editor's Note: The Easy Java Simulation tool greatly reduces the amount of programming required to develop computer models. Exercises in student-generated modeling are becoming much more widespread in physics education because of the opportunities for students to test and apply their own prototypes to explain and predict physical phenomena. SEE RELATED MATERIALS for a link to the EJS Modeling and Authoring Tool, which students will need to develop their models. This resource also includes a detailed instructor's guide, instructor's notes with solutions, laboratory exercises, and tips for constructing the models. Please note that this resource requires at least version 1.5 of Java.

This resource is part of a Physics Front Topical Unit.
Topic: Periodic and Simple Harmonic Motion
Unit Title: Conservation of Energy and Forces on a Spring Student-generated computer models are becoming much more widespread in physics education because of the opportunity for kids to test and apply their own prototypes. This resource lets them develop a model for a mass on a spring. It opens as a simple simulation for them to explore, record, and analyze data. Afterward, they use the Intro SpringLab computer modeling tool to built their own model and compare results with the real-life experimental results. Resource requires Java. Link to Unit:
