Teachers may use this as a poster to make whole group predictions of which items will be heavier or lighter than the student's scissors. You may also run individual copies for students to record their predictions.
When we did this whole group, I had two colors of post-its. One color represented students predictions of heavier and the other color represented lighter. Students wrote their name on the respective post-its and placed it on the poster. When we finished the activity, students whose predictions were correct got a smiley face stamp. It was a very good visual. :)
