Lesson Summary

The purpose of this lesson is to introduce students to the concept of magnetic fields and magnetic field lines. Students will also learn about how one species of worm, C. elegans, detects and uses magnetic fields to navigate in their environments. Upon completion of this lesson, students will be able to:

  • define magnetic field and describe common examples of magnetic fields;
  • explain how magnetic field lines are draw and how to use them to determine the relative strength of a magnetic field at different places around a magnet;
  • define polarity and explain how the polarity of Earth’s magnetic field impacts how animals navigate; and
  • describe how animals use Earth’s magnetic field to navigate.
