Make A PowerPoint Presentation into a Video
If you are good at making PowerPoint presentations or even if you are not. You could easily make it into a video for YouTube or a future presentation. It would also be nice to make a video of a trip that you took. I made this video and it is very basic but you will get the general idea.
PowerPoint is a wonderful teaching tool. You could use bullet form or special effects. You could make colorful presentations to deliver a more powerful and exciting lesson. Putting a video on YouTube also gives you the option of selecting public or private for your video. If you make it private you could still send the link to someone.
