PowerPoint projects for this course should be well-crafted and professional, and about 25-30 slides in length, with narration or narrative text as part of the program itself (and not simply presented, for e.g., as presenter's notes in a powerpoint presentation).
the numbers 25-30 slides are just guidelines. You may have more slides if you like.
Your narration can be voice-over or textual
You should have captions where appropriate
The "narration" can be pretty straightforward. It is the "story" that links the slides together
If you look at any of the slide sets from the first part of the semester, there is a set of word slides linking together the various images
(Note, as mentioned above written "narration" should be part of the program itself and not simply presented as off-slide notes in a PowerPoint presentation. That is, the PowerPoint "show" itself should be self-contained. The same priciple is also true as it might apply to a web page presentation.)
To see what the presenter's notes are all about, if you go to your PowerPoint program and click on the "View" tab at the top (usually at the top) you will have the options . . .
Some people sometimes put the "narrative" (the story that links the slides together) on the "Notes Page." But when one does that they can not see the slides and the notes at the same time.
So don't put your "narrative" there
The minimum format should be slides with information on your project, with relevant illustrations. You may, of course, experiment. (But avoid items flying around and appearing randomly.)
