FINAL PROJECTS

 

Each group should prepare a presentation lasting approximately 20-25 minutes. All group members should be involved in describing the work (i.e. take turns in speaking) and be ready to answer questions. A hard copy of the presentation (or if you want an extended description of what you did) should be handed in to Francesca right before you talk. If you want the pdf file of your presentation to be posted on the class web-site, email it to Francesca the evening before your presentation date.
