3 important things
The first most important things we learned are; how the electron is attracted to diffrent things and surfaces dependingon the positive or negative charge.
The second is how an electron orbits around the nucleus and the overall structure of the atom which is what gave me the basic understanding of what an electron is.
The third and final thing thats important is how electrons are charged with friction and what things conduct and things that are insulators and do not let electrons passthrough.
LAB
The lab that helped me the most was the Vanda graph which showed me how electrons and charge can pass through diffrent objects and the reaction is pretty much instantaneous.
