Fold this in half lengthwise. Starting at the lengthwise fold, draw lines 5.5 cm long in the middle crease and the two creases closest to the ends of the paper. Carefully cut the lines you drew making sure that the paper is still folded. After cutting, unfold the paper to show three slits in the paper. Put the two striped strips of paper together so that their labels touch one “START” another. Insert the ends of the strips up through the center slit and then pull “START” them toward the side slits. the ends of the strips into the side slits. Pull the ends of the strips and watch what happens at the center slit. pulling the strips through the slits until you can make the two strips come up and go down at the same time. Data (Table and Observations): Neatly copy the data table below into your lab report. With your strips of paper fully pulled through the center of the colored paper, record the lines of the magnetic pattern into the top row of your data table. Pay close attention to the width of each line. In the second row, state the type of magnetic polarity each line represents normal ─ or reversed. In the third row, record the age of the rocks directly below each line. Left Edge Center Right Edge
