This week, we discussed forces and charges. We conducted a "magic tape" lab, in which tape would be attracted to a person's hand after being pulled off a table. This occurred because opposite charges attract. In this case, the tape is attracted to the hand because the two are different charges. However, if I was to touch the tape and neutralize it, it would not be attracted to my hand. We also discussed insulators and conductors. Insulators are materials such as wood and rubber that hold on to electrons, while conductors such as metallic materials, do not.
