1st Moment: Start the class by asking:

Did you have more than one cell phone? If yes, how many?

How did you do the disposal of the old appliance―sold it, changed it, threw it in the trash?

Do you know of any point of collection/disposal of technological waste?

How long does a cell phone last?

Did you know that up to 80% of the components of a cell phone can be recycled? Do you know that there is the Electronic Junk Law?

- Conduct the dialogue with the students, adding some information and leaving others open for them to discover in the research.
