Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
Like poles with repel and unlike (opposite) poles will attract.
What was the point of this activity?
The point of this activity was to show students how everyday items are magnets, even ones we would not suspect. It clears up misconceptions students may have regarding this topic.
Explain how you would introduce this to your class?
I would start this topic by asking what my students already knew about magnetism and start and open ended discussion about it. As a class, i would ask if they though certain items were magnetic or not.
Where do you see a student having difficulty with this?
I honestly do not see much difficulty with this lesson but if there had to be any, some may not understand why some of the items were in fact, magnetic.
What changes or extensions could you do to this activity?
I would give my students magnets and have them go around the school to see what magnetic items they could find.
