Topic and theme presentation

Hello!
This one is our first oral presentation.
Here we expose the topic of our work. We know that we have much that to improve, but to be the first one is not not bad at all.
We hope that you like.
We are a bit nervous and isn´t here a component (Laura).
In the video we are for this order of participation:
- Sara
- Ricardo
- Inmaculada
- Gloria

Bye!!
