Once you know you can see PowerPoint on your computer, start the audio MP3 of this lesson below and then click on the 'Download File' and choose the option to open with Microsoft PowerPoint which allows the slides to show with full animation.
Above is the Audio MP3 player for Lesson 1 which is about an hour long.
On Slide 2 in the 2nd bullet there is a reference to a 'History of Man' Video which you can view above, separately, since I spoke comments into the audio MP3 while viewing them.
Above are the 'Activation Sheet' and PowerPoint notes files that accompany this Lesson 1 - Use the Fullscreen option to view properly. Caution: I don't recommend you print the PowerPoint notes file due to dark slide design!
