What do we mean by charge and why do we think it moves?

The video below shows the electric phenomenon explored in the simulation. Experiments like this with different materials are why we think that there has to be something in atoms that moves and "carries" charge.

1. Go to the aluminum can interactive (https://www.physicsclassroom.com/Physics-Interactives/Static-Electricity/Aluminum-Can-Polarization/Aluminum-Can-Polarization-Interactive ) .

2. Explore-Interact-Learn:
Investigate the interaction between a glass rod and a rubber rod and the aluminum can. Play
with the simulation, moving the rods about the screen and observing the behavior of charges within the pop can. Then complete the models below by shading in the areas where electrons tend to congregate most densely.

Conclusion:
Describe what must happen inside of an aluminum can in order for it to be attracted to a
positively-charged and to a negatively-charged object.

Required

Shade in the area that should have the highest concentration (number per unit area) of negative charge. Be sure to think about distance between the rod and the can.
