Slinkies as Solenoids
In this activity, students use an old fashion children's toy, a metal slinky, to mimic and understand the magnetic field generated in an MRI machine. The metal slinky mimics the magnetic field of a solenoid, which forms the basis for the magnet of the MRI machine. Students run current through the slinky and use computer and calculator software to explore the magnetic field created by the slinky.

Thrown for a Loop
In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn to calculate the energy of this loop in the magnetic field. Several example problems are included and completed as a class. A homework assignment is also attached as a means of student assessment.

Koch's Crickets: A Study in Etiology
Students apply Koch's Postulates in an attempt to discover the causative agent of "Pink Plague" a disease that has struck a group of commercially raised crickets. During the course of this exercise the students will isolate the suspected pathogen from one of a group of infected crickets. They will then characterize the isolated organism and use it to infect a new group of crickets to see if they can reproduce the same symptoms in the newly infected group. Reisolation of the suspected pathogen fr
