MRI Safety Grand Challenge

Abstract:: This module was written for a first year accelerated or AP physics class. It is intended to provide hands on activities to teach end of the year electricity and magnetism topics including the magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's Law, and Faraday's Law. During the module, students utilize these scientific concepts to solve the following problem: A nearby hospital has just installed a new Magnetic Resonance Imaging facility, which has the capacity to make a three dimensional image of the brain and other parts of the body by putting a patient into a strong magnetic field. The hospital wishes for its entire staff to have a clear knowledge of the risks involved with working near a strong magnetic field, and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks involved, the physics behind those risks, and the safety precautions that should be taken by all staff members. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

Radio JOVE Data Analysis

Abstract:: The objectives of this lesson are to understand the characteristics of the data that is collected using the Radio JOVE antenna/receiver system. Using calibrations for the equipment, one can determine a proper measure of the peak intensity of the output, identify the duration of the solar or Jovian radio activity, and calculate the approximate total power emitted by the source. Master these concepts by completing example problems.
