Electrical charges

We are going to start a new topic, this time we are going to deal with ELECTRICITY and MAGNETISM.

• What's happening in the photo?
• How is that phenomenon produced?
• Do thunder and lightning occur at the same time?
• If so, Why don't we listen them at the same time?

LET'S HAVE A LOOK TO AN EXPERIMENT, it will be very useful to understand the different concepts.

Do you think all objects have electric charges?

We can have

• Objects positively charged.
• Objects negatively charged.
• Objects which are neutral.

When we rub to objects made of different materials, we are creating STATIC ELECTRICITY.

LET'S REVIEW THE VOCABULARY WITH THIS ACTIVITY.
