Electricity (6th Grade)

Hello everyone!

In 6th grade we are studying the ELECTRICITY. Let us show you some of the contents learnt:

We know that all objects have electrical charges. Some charges 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:

- But when we approach 2 negatively charged balloons, they repel:

This is STATIC ELECTRICITY.

We also know ho to build an electrical circuit, which carries electrical current:

Finally, we can say if some materials are conductors or insulators after adding them into the circuit. For example:

Wood: insulator.

Pencil lead: conductor.

Pencil lead: conductor.

Salt water: conductor.
