The University of Michigan's educational site called Windows to the Universe (last mentioned in the January 6, 1999 Scout Report for Science and Engineering
) has added many new lessons to their content. Highlights of these include two activities centered around magnetism. Clicking on the links to the Student Activity Sheet and reading the Notes to the Teacher are essential for getting the most out of the activities. To undertake the magnetism lessons, first follow the instructions to make the homemade magnetometer. Then, you can do neat activities modeling real-world uses of a magnetometer instrument, such as exploring Earth's magnetic reversals.
