Students in Maria Nunez’s fourth grade class at Mariposa Elementary are studying magnetism by exploring the properties of various materials that respond to a magnetic field.  As part of their experiment, students were given magnets, a compass, string and paper clips to investigate magnetism. The activity included magnetizing a paperclip by scratching the surface of a magnet, exploring the earth’s magnetic pull by using a compass and watching it point towards the North Pole, then disrupting the needle of the compass by placing a magnet near the device. Students gained insight into what is a magnet and how it works. Pictured are Sasami Bagnall, left, and Kaitlyn Fiske.
