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 A 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 VOCABURALY WITH THIS ACTIVITY.
