How does TV affect teenagers??

My classmate Maria Luz talked about the effect of TV on teenagers; she used good and funny pictures and videos in a good way trying to demonstrate the real effects that provoke TV.

Maria Luz asked us some questions related to her topic, for example; what are the negative effects on teenagers?

Obesity, Alcohol, Risk behavior: Sex, Smoking, Stereotype.

We as a teacher how can help our students to watch TV in a healthier way?

In my opinion I think that Maria Luz used in a good way the space in her presentation, she moved around the classroom and she made us participate a lot.
