|제목||Masses and Springs Simulation Homework|
|설명||This homework explores the basics of springs and masses with phet's simulation. The homework consists of one problem with multiple questions. This activity was developed in 2003 before most of our research with PhET interviews and before we developed the Inquiry Guidelines. Therefore, the lessons are more directed then we would now recommend. Also, this activity was used in a course with very large enrollment (200+), so many questions are constrained to being multiple choice or numeric for computer grading. Please email email@example.com if you are a teacher and would like a solution key.|
