NANSLO Remote Lab Activity: Charge to Mass for Physics

This NANSLO lab activity is self-contained and can be used in physics courses. In this activity, a gas discharge tube and a pair of Helmholtz coils are used to examine the motion of electrons in a magnetic field. The lab activity includes background information on how these instruments are used to examine the motion of electrons in a magnetic field and provides equations that are used to measure the ratio of the electron charge to the electron mass by determining the potential difference used to accelerate electrons, the magnetic field strength, and the radius of the circular motion of the electron. The lab activity also includes a pre-lab exercise, lab exercises, data analysis activities, and an optional advanced analysis activity.
Microsoft Word NANSLO Remote Lab Activity: Charge to Mass for Physics uses a gas discharge tube and a pair of Helmholtz coils for investigation of how motion of an electron is affected by the presence of a magnetic field, measurement of the ratio of the electron charge to the electron mass, calculatation of e/m from individual data points, and activities for graphing measurements. It contains a pre-laboratory exercise, laboratory exercises, data analysis activities, and an optional advanced analysis activity for the assigned lab. (191 KB)

Quality Note:
Curriculum experts in this discipline worked with others to define learning objectives needed for this lab activity. Draft activity was shared among faculty. Based on feedback, lab activity was modified prior to distributing as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
