There are a couple of different approaches you could take with your classes. You could go with basic paper and pencil, have some magazines or pictures for the students to add. Or you have them create it using google docs.
I have done both but this year I have my students complete everything online. This allows them to work on it at school or at home, they do not have the excuse of loosing their work, and they can share it with me and I always have them on file online (instead of creating a file at school).
But if you don't have technology have them create one the "old fashioned" way. It's something different for them to express themselves and the students will appreciate the change of pace.
resources for you....
With any project make sure to have a rubric for your students to follow. I've posted one as an example. It probably could improve (and will when I come back to this unit next year) but feel free to look at it and change whatever you need to.
Also, remember that I teach a combination of Tech and Health class so I have a Tech LT's they have to meet as well as health LT's.

Here is a youtube video that explains how to being on online. It's pretty straight forward. I always allow my students to look back at the powerpoint if they need more guidance.
