I recently came across this video tutorial below showing how you can use PowerPoint to create engaging animated videos (yes, really). As the video illustrates, it is possible to create some fun, engaging, and impressive animated videos with only the tools and resources built-in to PowerPoint.
This video provides a good idea for a digital project you might have students create in lieu of another assignment format. The video also highlights some free resources that may be good for you or your students to use in the creation of other digital projects.
