CH 4-3 is not a YouTube video, but the actual narrated Power Point. There is an embedded video on slide #2. To use CH 4-3:

1) Click and open this power point video file.

2) Start the slide show (Slide Show Menu – from the beginning)

3) If a “Security Alert” box opens, select “Enable external content for this session.

4) Power point video will now play. On slide #2 you will be prompted to start the embedded video. After you start that video, move your mouse away from the embedded video picture.
