Description:

In this activity, students construct a magnetometer from a magnet and a spring balance and use it to locate buried objects in a tray. The activity will reinforce the idea that local fluctuations in Earth's magnetic field can be used to locate underground materials having magnetic properties. Working in groups, they will construct their instruments and use them to survey a large flat container in which iron objects have been buried. Follow-up activities, a student worksheet, and discussion questions are provided.
