Have adult supervise activity to help with some management problems-like holding the paper tightly. Have all the items for the students to test in one box and all the magnets in another box. Pass out magnets first. Let students choose their magnet and then decide on the material they will use. Students decide who will use the magnet and who will hold the object 4.
Adult encourages discussion and helps to direct student s observations.
Students can change jobs during the activities. Allow enough time for students to use each item.
