I always like making PowerPoint presentations. It is actually something that I really enjoy. I especially enjoy getting the opportunity to make a non-linear presentation. This is not the first time I have made one, but I always enjoy the practice! One “a-ha” moment that I had while making the presentation was I had never really thought about all of the possibilities there are using PowerPoint to teach my future students. A second one that I had was teaching students to use PowerPoint. It expands the mind and uses creativity! The third “a-ha” moment that I had while making this presentation was using Microsoft Office 2007. This is the first time I have made a PowerPoint presentation on Microsoft Office 2007. It was strange getting to know where all of the buttons were located, but I figured it out and now I feel confident using it!
Incorrect! The correct choice is ‘C.’ A meteor is also known as a shooting star.
