Powerpoint Presentation

Our math class is doing a project that involves landscaping. We need to create a Powerpoint presentation detailing how we landscaped our school’s grounds. We think that the easiest way to do this is to create a video and show it during our presentation. Unfortunately we have no idea how to do this. We would like to put the video directly on the slide but have it so it would play when we told it to. Please suggest anything that you think would help. Thanks so much!

I did a powerpoint presentation and how do i get video to play on slide when i have the slide on slide show?
