What is the difference among: lightning, lightning strike and thunder?
--LIGHTNING(RAYO) IS AN ELECTRIC DISCHARGE.
--LIGHTNING STRIKE (RELAMPAGO) IS THE LIGHT PRODUCED BY THE LIGHTNING
--THUNDER (TRUENO) IS THE NOISE CAUSED BY THE LIGHNING.
Lightning is produced by a strong electric current created between the negative charge at the bottom of the thunder cloud and the positive charge or the Earth’s surface.

An atom
Why do the balloon and the can of coke attract?
Electrical charges.
Negative charges can move from one place or object to another.
If an object has more positive than negative charges, it is positive charge
If an object has more negative than positive charges, it is negative charge
If an object has the same number of positive and negative charges , it is neutral.
Objects with opposite charges attract repel Coulomb's law

Do you think all objects have electric charges?
We can have:
-objects with positive charge.
-objects with negative charge.
-objects which are neutral.
When we rub to objects made of different materials, we are creating static eletricity.
