Building Magnet Stations

• Please form groups of two

Have each person assume the following roles....

• String and ruler cutter
• Data person/questions

After opening the box, complete the following tasks...

• Cut through the “0” marks on both ends of your ruler. The trimmed rulers should end exactly at the “0” line on both ends.

• Cut the string into three equal pieces so each group has one piece.

• CAREFULLY stick the ruler to the top of the board. Make sure that the ZERO on the magnet side is flush with the surface of the magnet.

• Insert the eyehook just a few turns

• Tie a paperclip to the string

• Tie the string to the eyehook so that there is only a little slack when the clip is touching the magnet. (You should be able to make the floating clip fall by screwing in the eyehook)

• CAREFULLY stick the ruler to the top of the board. Make sure that the ZERO on the magnet side is flush with the surface of the magnet.
