In 6th Grade, we are learning ELECTRICITY.
We know that all objects have electrical charges. Some are positive, PROTONS, and some are negative, ELECTRONS.
Sometimes, the negative charges pass from one object to another. For example:
- By rubbing a pen to a piece of cloth, we pass negative charges from the cloth to the pen.
Now the pen is (negatively) electrically charged. So, it can attract small pieces of paper.
- Or by rubbing a balloon to a piece of cloth, we pass negative charges to the balloon. So, it is attracted to other objects:
This is STATIC ELECTRICITY.
We also know ho to build an electrical circuits. which carries electrical current:
Finally, we can say if some materials are conductors or insulators after adding them into the circuit:
