In 6th grade we have studied ELECTRICITY. Let us show you some of the contents learned:
We know that all objects have electrical charges. Some are positive, PROTONS, and some are negative, ELECTRONS.
- 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:
