Students investigate how many paper clips different types of magnets can pick up.
For the Teacher:
For the Student:
Magnet strength is related to the composition of the magnet - not the size. The relative strength of a magnet can be determined by counting the number of iron nails or paper clips that it will pick up and comparing it with the number that another magnet will pick up.
Be sure this activity includes some large magnets that are relatively weak and some small magnets that have a relatively strong magnetic attraction.
Experiment with the number of paper clips that can be held at different places on the magnet. Many more can be held at the poles than in the middle of the magnet. Following investigation, they should conclude that magnets are strongest at the poles, or ends.
Assess student Science Journals using the rubric below to check accuracy in recording predictions, observations, and conclusions.
